The latest (22.x) version of Magisk no longer supports the A/B Retention Script, which I have been happily using for a year or so, whenever I want to upgrade the OS on my A/B device (OnePlus 7Pro - GM-1917).

I am not upgrading Magisk from 21.4 to the latest 22.x because of this.

But at some point, I'll probably want to upgrade to the later version of Magisk, so i am wondering what steps I can take manually -- if possible -- to emulate the very helpful functionality of the A/B Retention Script under Magisk 22.x.

Or am I simply out of luck?

News to me. I had fixed it a little while back for 21402+, but I guess it needs something new again. Can you provide a log of the breakage? I'll take a look. 👍

Oh, I'm sorry. I was just going by the Magisk update log where it said that the A/B Retention script is not supported, so I didn't even try to upgrade Magisk and check it out. But I will check now and get back to you.

I just now tried upgrading Magisk to 22.0, and indeed the A/B Retention Script is available .. and it works fine!

So again, I apologize for my false alarm.

Here's what I did, for anyone else who might be interested ...

I don't have a new ROM for upgrade, so I just went to Settings->System Update->Settings and selected Local upgrade of the current ROM image that I had previously installed a few weeks ago. This could also be done with any new ROM that has been stored on /sdcard ... perhaps via the Oxygen Updater app, if like me, you happen to be using a OnePlus device.

After the Local upgrade completed, I went through the standard A/B Retention Script procedure:
* DO NOT (!!!) reboot after Local upgrade
* Install the A/B retention Script in Magisk
* DO NOT (!!!) reboot
* Select Install next to Magisk on the main page of the Magisk app
* Select Install to Inactive Slot (after OTA)
* Select LET'S GO
* When that completes, do indeed choose to reboot.

In my case, everything ran and came up fine.

Ah, that's not what it says; I believe you're referring to the Magisk Install to Inactive Slot (after OTA) option being unavailable on specifically Virtual A/B devices since it's a different verification process for the new slot which occurs after the reboot and we don't know how to work around it currently.

Oh, I've never learned what a "virtual" A/B device is, and that message about it confused me. I guess it must differ somehow from the way my OnePlus 7Pro A/B device is architected.

Well, in any case, I'm just glad that I can still use the A/B Retention Script.

Thank you for clarifying!

Well I'm really not sure then, I guess your device just has something that conflicts within xbin. My advice would be to uninstall, then use the advanced options file to skip symlink creation during an install by running this command beforehand:

`echo NOLINKS > /data/.busybox-ndk`
@osm0sis I decide to downgrade magisk to 20.4 & there's no problem with symlink. But on 21.x to 22.x I should nolink it.

Yup that's it. Anything else I could provide (boot.img probably), since the boot log won't help much, I had taken it many times & the result was the same as I posted here ?
Well arguably it's something related to a change in Magisk on your device, rather than my module or my installer, since the symlinks should be the same regardless since they're in xbin. 🤔

Can you give me the output of `su -c magisk --path` on 20.4 plus the list of symlinks in the busybox module, and then the same on 22.0?

Magisk path is the same for both, they're in /sbin. Differences are in /sbin/.magisk/mirror, on v20.4 it has folders named system, data & vendor while on v22.0 it adds / includes folders cache, persist & sepolicy.rules. For sepolicy.rules folder I saw it linked to modules folder.
My apology I don't really get what you mean by "symlink in the busybox module". On magisk v22.0 I use nolinks since if I install it directly / without nolinks command it will bootloop my device, inside busybox module folder only busybox file no symlinked applets.
I attached magisk log for symlinked files on magisk v22.0 & 20.4

    They're just whatever the zip reported when it failed. It shouldn't flash "*.zip" though, that's weird. I've never seen that before.

    Can you show me the contents of the directory? And the zip? You should try enabling verbose and logging to see what's going on with the flashing as well, and show me that.
    I attached both.
    Its gettin strange: I deleted the FlashAfterUpdate folder in main storage so only the one in /data remained. Flashed the Rom again, but this time manually (not through updater app). Now it worked. Dont know what caused this.
    What is also strange:
    - the deleted folder was automatically restored
    - in both folders a 'disabled' folder was created automatically (see screenshot)
    [EDIT I just had a closer look at the script and realized the Behavior of the two points above is intentional]
    - although I have a verbose file, too, no output of the zip can be found in it (still empty file) [EDIT I'm attaching the relevant part of orange fox recovery log file so you can also see the output of the zip]

    Well, in spite of the stuff I don't understand, seems that it works now. Thanks for your answer, anyways 🙂👌🏻

    @osm0sis

    I just wanted to let you know that the most recent magisk adb-ndk works perfectly with the fastbootd that's used in Orange Fox and TWRP. I've been able to unlock the bootloader, and flash custom roms on 3 different devices without any issues via OTG. Stock firmware can also be flashed. I haven't had a PC in 8 months and this has been a blessing to me.

    Finally figured out the right method for keeping SafetyNet passing even though the new Virtual A/B slot Incremental Google OTA process needs the updated slot to stay unrooted to pass the post-reboot checks:

    (Note: A prerequisite is you must have Developer options > Automatic system updates turned off. I do this as soon as I set up any rooted device on stock ROM.)
    1. Attempt to Download & Install update via the dialog, it will fail due to the rooted current slot. This is fine and what we want just to have it downloaded first.
    2. Unroot current slot WITHOUT rebooting by restoring the stock boot/recovery images.
    3. Download & Install update again, which will work now, but DO NOT reboot after. Note WiFi must be/stay enabled for this step.
    4. Dump the updated slot's boot/recovery images, then root patch the image needed for your device using the Magisk app, and copy the new magisk_patched.img to your PC.
    5. Re-root the current slot using the Magisk app Direct Install, so in case the update somehow fails you'll be back where you started (rooted on the current slot).
    6. Turn on Airplane Mode, then reboot from the update dialog.
    7. Let OTA finish after reboot, leaving Airplane Mode on, make sure you're on the updated slot, then reboot to fastboot.
    8. fastboot flash the magisk_patched.img to the appropriate partition, then boot the device.
    9. Make sure you're rooted again and still on the updated slot, then finally, turn off Airplane Mode.
    Ta-da! SafetyNet never caught that you were unlocked and unrooted, continues to pass, and Play Store's still Certified and Google Pay still passes Contactless setup checks.

    Still got a few things to do before I update the rest of the thread here, but the Magisk Modules Repo has been updated with busybox 1.32.1. :)

    In the meantime, here's another little one-off simple Magisk module, which I may or may not keep updated going forward. payload-dumper-go ported the original Python payload_dumper into Go, meaning it could now be cross-compiled, so we can now use it to extract payload.bin OTA zips on-device with no Termux/Python overhead! It took some cross-compile hacks and a wrapper to get it working smoothly on-device, but that's all good fun. :cowboy:

    Cross-compile process notes and other builds in the official payload-dumper-go thread here: https://forum.xda-developers.com/t/tool-a-quick-android-ota-payload-dumper.4173271/#post-84721689 (y)

    Only issue I've seen so far is that on a HUGE payload.bin it can run out of memory and fail to extract the largest partitions, regardless of platform, so I believe that's more of an issue with payload-dumper-go itself than my compiles. It certainly works very well to get boot.img and recovery.img, etc. from a Full OTA quickly. Generally I've had best results extracting on my OnePlus 8T, which is a decently beefy device. 🤘

    Forgive me if this is OT (and feel free to delete this post if it is). But since lots of helpful tools and utiltities are discussed in this thread, I'm guessing that perhaps someone here would be knowledgeable about my question:

    I do a lot of testing of different ROMs on my OnePlus 7Pro. Once I get a new ROM set up, I go through a time-consuming and annoying procedure of resetting a lot of the basic Settings to values that I prefer. I'm wondering: is there a utility that will allow me to save a collection of Settings into some sort of file that I can push to my device with a newly flashed ROM, and another utility (or perhaps the same one with a different option) which I can use to install this group of saved settings onto the device, all at once?

    Thank you in advance for any thoughts or suggestions.
    I use to build and flash a LOT of custom ROMs for my previous phones. I found that a LOT (but not all) of the customisations were stored in the android settings. As such, I built the saving off of these settngs, and the generation of a script to reinstate them into my app TeMeFI. You can find these functions under Current State>Settings>* NB: All the script code is available from the app.

    I generate a list once I have my set-up all done, save that off to my PC (a Generate Set All). Then, when I flash a new ROM, I generate its settings and save them off. Then compare the two and selectively re-instate the settings. If you repeatedly re-flash the same ROM, you can create a script file to reinstate as much as you can. But, different ROMs may have different settings, so you need to review the differences. A lot of ROMs kang the features off each other, so use the same setting.

    excuse my lack of knowledge; is this good for 'magisk install'? i'm on your 'busybox for android ndk' 1.31.1(13123).
    No, you should probably wait for me to push the stripped release builds to the Magisk module repo.

    Not long now... 😎

    Or (for Google devices) grab both the full OTA and the Factory images. Set airplane mode. Reboot to recovery. Adb sideload the OTA. (If you have a modified kernel you may need to restore the original boot image for signatures to match.) Allow the update to boot. Extract boot.img from the factory image and patch it in the phone using Magisk. When the OTA updates have completed, flash the modified boot.img in the bootloader. Boot up and disable airplane mode.

    The key thing is not allowing the phone any access to the net whilst it's modified and unrooted.

    osm0sis' Odds and Ends -- Misc./Batch Tools, Flashable Zips, Scripts, etc.

    General Information


    In a nutshell, I just wanted a single thread to gather links to some of my other, larger projects, but also serve as a spot I could put some smaller scripts and zips I've created that I don't think merit their own separate threads. This is partially for my own sanity and will hopefully make it easier for others to find some things as well. A lot of the stuff here was developed with the GN, N5, N7s or N5X, OP5/T, OP6/T, OP7Pro/T or OP8Pro (my devices) and Windows in mind, but could generally be applicable to most devices either out-of-the-box or with some slight modification. If you see something that inspires you, go ahead and mod it, just let me know and give me some credit somewhere. If anyone would like to know the specifics of what's in a particular script that I haven't already linked to more information on, just let me know and I'll post that in here as well.

    Note: Older zips with a "cwm-" prefix are NOT only for the now-defunct ClockworkMod Recovery, the prefix was used to denote a flashable zip before I adopted Chainfire's "UPDATE-" prefix. Please use a currently maintained recovery, like TWRP, for all zips to ensure the best compatibility/results.

    My development work on my many projects comes out of my free time, so if you enjoy this project or anything else I've done on xda, please consider sponsoring my ongoing work using my GitHub Sponsors profile. For a one-time donation you can hit the donate link from my profile. Thank you for your support!


    Misc./Batch Tools

    • AnyKernel3 (many devices) - link
      AnyKernel was a simple template for an update.zip that could apply any kernel to any ROM, regardless of ramdisk to reduce the chance of any issues arising from the custom kernel pairing. The drawback to this is that some kernels require modifications to the ramdisk to enable/set up kernel features, and in the old AnyKernel format there was no way to do this. AnyKernel3 pushes the format even further by allowing kernel developers to modify the underlying ramdisk for kernel feature support easily using a number of included command methods along with properties and variables to customize the install experience.
    • APK-Patcher (many devices) - link
      A proof-of-concept, simplifies APK modification to make it easier for modification creators to keep creating. Using JesusFreke's brilliant bak/smali and iBotPeaches' excellent apktool, modified to run on-device along with the various binaries required, allows on-the-fly APK modifications to be applied via recovery, to whatever ROM APK is present, taking the constant update burden off of the modification creator. The zip is smart and automated, using the APK name to run all the various parts involved for complicated patches and is extensible to any number of APKs in a single zip.
    • Android Image Kitchen (many devices) - link
      A collection of Windows/Android ports of the necessary Linux utilities for Android image (kernel+recovery) mod work, and my own automation script to unpack, edit and repack the ramdisk. Other guides/scripts exist but none of them are universal for target device, compression and/or developed for Windows/Android. Now also Linux builds to bring my improved featureset back to where it came from, recently extended to macOS as well. Has been extremely useful for me in my messing around with kernel ramdisks.
    • ADB Screenshot (many devices) - attached
      Take screenshots while in recovery. Useful for development of recovery apps or error reporting. Original method had lots of different threads around with the general method for various devices but I figured out a couple tricks required for getting it working on the Galaxy Nexus and then automated the process. Tested and confirmed working with both pixel formats of CWM and TWRP. More information in this GN Q&A FFmpeg thread. New method uses fb2png and should work on all ARM devices.
    • ADBsync sdcard Backup (many devices) - attached
      Backs up the entire sdcard so that you can have a complete snapshot of your device when you make periodic backups, and be able to restore things exactly as they were. Automates the sync process of Renate NST's great adbsync utility which makes only newer files get pulled, significantly decreasing backup time for the sdcard compared to "adb pull". Original version posted in the old adbsync thread. Defaults for devices with /data/media/ internal sdcards (Nexus devices, etc.), but is easily customizable to backup other mountpoints or backup via ADB over WiFI.

    Flashable Script Zips
    • TWRP A/B Retention Module script (many devices) - link
      We need an interoperable root ecosystem again. A/B and system-as-root were a big setback to the root community in this respect. To help alleviate this issue, this atypical Magisk script zip "module" will keep TWRP installed to both slots when flashed from Magisk Manager after an A/B OTA has installed in the background, but before you use Manager to install Magisk to inactive slot.
    • Nexus BootUnlocker script (GN, N4, N5, N7 '13, N10) - attached
      I don't know about everyone else but sometimes I find I've rebooted into the bootloader only to realize I've forgotten to unlock it in segv11's excellent BootUnlocker App beforehand. Well, I decided to make a BootUnlocker Script for my Galaxy Nexus so I could just boot to recovery quickly, unlock, then adb reboot-bootloader (or use my Reboot To Bootloader script below) to get back without having to fully boot the OS to make the change. Also extremely useful in the case you aren't able to boot. As with the app there is no data loss like there would be with fastboot, allowing you to relock for safety. Originally posted in the GN EDIFY Scripting thread. Modified for the newer Nexus devices and combined into a single Nexus BootUnlocker zip with tamperbit reset support added using information from the BootUnlocker App Dev thread. For newer devices using Factory Reset Protection (N6 and later), the BootUnlocker Script can't directly toggle the lockstate due to new security tokens, but it does now toggle the ability to use "fastboot oem unlock" without needing a booted device.
    • N7 BootUnlocker script (N7 '12) [creation guide] - link
      The Nexus 7 2012 is a special case. Per-device encryption of an entire partition makes it impossible to support the N7 '12 in a simple root app, or flashable zip as above, however using my guide and included script you can now create a working BootUnlocker Script Zip for your specific device. As with the above scripts there is no data loss like there would be with fastboot, allowing you to relock for safety.
    • sdcard Fix Permissions script (many devices) - attached
      A little flashable zip script to fix ownership and permissions of files and directories on the sdcard to what they would be if Android OS had put them there itself, since some apps can't access pushed files that have root.root as owner/group. This is useful when restoring to your sdcard backup, as with my ADBsync sdcard Backup batch script above, since generally, pushed files get root.root from adb shell and higher permissions than usual. Also a solution for a bug where sdcard files get lower permissions somehow, resulting in similar access problems. Currently written for devices with /data/media/ internal sdcards (Nexus devices, etc.), but could easily be modified for other mountpoints. No longer required on Oreo since it fixes these itself at boot.
    • SUmount script (many devices) - attached
      Another tool for the toolkit of anyone using Chainfire's SuperSU or topjohnwu's Magisk systemless root, this simple flashable zip script toggles the mounting of the su.img, magisk.img and magisk_merge.img while in recovery to allow easier access to the /su, /magisk and /magisk_merge filesystems, simplifying manipulating it via ADB shell, AROMA Filemanager or TWRP's terminal/file manager. Especially useful to anyone who uses su.d/post-fs-data.d scripts or can't boot due to some issue with a user addition in /su/su.d, /su/bin or a Magisk module.
    • unSU script (many devices) - link
      While experimenting with Chainfire's brilliant SuperSU systemless root, I discovered that uninstalling the older style system-modifying root through his app (<2.60) didn't restore all of the modified system files correctly, so I wrote this script to do so and aid in people wanting to unroot from recovery. Expanded to support uninstallation of Koush's SuperUser, phh's Superuser, SuperSU Systemless (su.img and BINDSBIN), Magisk, LineageOS addonsu and custom ROM su binaries.
    • Adreno Systemless Installer script (N5, N6, N7 '13) - link
      For use with Qualcomm's official updated preview GPU drivers packages for Adreno 3xx/4xx-powered Nexus stock images, this is technically a script and not an installer because it is only a different frontend to take whatever device zip from Qualcomm is in the same directory as it (also searching /sdcard) and unpack it then install it into the SuperSU systemless root /su filesystem instead of the usual /system, or Magisk if detected.
    • Kernel MultiROM Injector script (many devices) - attached
      Intended for use in Chainfire's excellent FlashFire app to automate re-injecting the current boot image ramdisk with Tasssadar's brilliant MultiROM's trampoline bootmenu; this avoids having to do this as an extra step in MR-TWRP following an OTA, ROM Delta or SuperSU update. Should work for all EMMC devices with MultiROM installed.
    • GN PIT Editor script (GN) - link
      Dumps and alters the Galaxy Nexus' Partition Information Table (PIT) to reclaim unneeded space from the /cache partition and add it to /system to allow for larger ROMs and GApps packages to make continued support for Lollipop+ easier. The resulting file is byte-for-byte identical to those created by external tools like PIT Magic, so that it may be flashed back to the device in Odin Mode to complete the repartitioning.
    • Kernel Emergency Reset script (many devices) - link
      Basically a go-to cure-all for custom kernel users experiencing issues after an upgrade due to old settings left over in a kernel control app (eg. franco.Kernel updater, Trickster, etc.), or problematic init.d/userinit.d scripts. It's also useful if you just want to make sure you're running clean defaults without conflicts.
    • Reboot To Bootloader script (all devices) - attached
      Those who prefer using CWM may have noticed a couple of things missing that the other popular custom recovery, TWRP, has built-in. One of these is a file explorer/manager, which is answered by amarullz' brilliant AROMA Filemanager. Another thing I found myself wanting is a way to reboot back to the bootloader once I'm in recovery, so I created this very very simple flashable zip script. (No longer required on CWM >=6.0.3.5). Note: Once in the bootloader, "Start" will boot you back to recovery. Not sure why, but it's not a big deal, just reboot normally from recovery at that point.

    Flashable Installer Zips
    • Flashlt Installer (many devices) - attached
      Installs my Flashlt script to allow easy flash and dump of boot, recovery and radio/modem (possibly others) EMMC or MTD partitions while booted, and trimming of null characters from files. Also installs a script zip that makes flashing boot.img (kernel), recovery.img, and radio.img/modem.img (baseband) files via recovery simple. It aims to save the average user the hassle of repacking their own image zip, or using the command-line or fastboot to flash it. Place an appropriately named file in the same directory as the zip and flash away! Should work on all devices with normal partition naming ("boot", "recovery" and "radio" or "modem") which accept Android standards-compliant images (including a/b slot devices like Pixel). Extremely handy when used with amarullz' brilliant AROMA Filemanager, and/or my Android Image Kitchen: Mobile Edition (linked above).
    • Busybox Installer (all devices) - attached
      As a byproduct of building my own static busybox compiles in all supported Android architectures for my AIK-mobile package I figured I might as well offer them up separately as well since there weren't any providers making Android x64 builds when I was researching. The installer detects what architecture (ARM/ARM64, x86/x86_64, MIPS/MIPS64) your device uses and installs the correct busybox binary accordingly. It then cleans up any symlinks from a possible previous installation in the same directory and generates new symlinks directly from the output of the installed binary. Detects and supports "systemless" root via SuperSU/Magisk installation as well. Please read the release post about applet inclusion and special features.
    • nano Terminal Editor Installer (many devices) - attached
      A simple installer to push my own static Android ARM build of the nano editor binary to /system/xbin/ along with the required files in /system/etc/terminfo/, and a wrapper with optional parameter to choose your terminal. Detects and supports "systemless" install via SuperSU/Magisk as well. It can then be used from Terminal while booted from that point on. Each time you flash it also temporarily enables use in recovery by pushing a script to /sbin/nano with the required environment variables, so you can then trigger it from recovery shell or the console in amarullz' brilliant AROMA Filemanager. Makes it extremely easy and worry-free to tweak and mod on the go, knowing you can edit the faulty build.prop or init.d script if something goes wrong.
    • adb + fastboot Installer (many devices) - attached
      Marshmallow removed adb from the /system/bin directory. For those wanting this functionality back, here's a simple installer to push static compiles of adb and fastboot to /system/xbin and uses a command wrapper to point adb to the correct HOME directory and set TMPDIR for compatibility. Detects and supports "systemless" install via SuperSU/Magisk as well. It can then be used from Terminal while booted from that point on.
    • Nexus Media Installer (many devices) - attached
      Custom ROMs often don't include the Google ringtones/notifications/system sounds and bootanimation, instead including numerous, terrible sounds and often less-than-desirable visuals. This zip installs the Nexus media for recently-retired Nexus devices, using the zip name (also reading from /data/.nexusmedia) to allow user choice, systemlessly installed (SuperSU and Magisk supported) or with an addon.d script to survive a ROM update or dirty flash.
    • mtd-utils Installer (many devices) - attached
      mtd-utils (flash_erase, nanddump, nandwrite) are necessary for mod work on a number of Android devices using mtd/char devices instead of the more standard emmc/block devices, and where the busybox versions have been less reliable in the past (especially where it doesn't include flash_erase), using the official suite is preferable. The older ARM builds available on XDA were about a decade old, so I worked out how to configure and cross-compile from the latest source. Detects and supports "systemless" install via SuperSU/Magisk as well. It can then be used from Terminal while booted from that point on.
    • ZipSigner + Zip Installer (many devices) - attached
      Signing zips and APKs on-device has always been a tricky proposition due to memory requirements of the old SignApk.jar, running a jar on an Android device, and other complications for script-based zips. Android has always been missing a zip binary (for unzip see my Busybox Installer). ZipAlign is also handy if you do APK work. To remedy this once and for all, here's a simple installer to push my dexed version of topjohnwu's brilliant zipsigner.jar and static ARM compiles of zip and zipalign to /system/xbin and uses a command wrapper to run zipsigner with Android's own dalvikvm. Detects and supports "systemless" install via SuperSU/Magisk as well. It can then be used from Terminal while booted from that point on.
    • odex Script Installer (all devices) - attached
      Based on the great work and binaries from this thread, a simple installer to push my odex script along with the required dexopt-wrapper and zip binaries to /system/xbin and set the appropriate permissions. Automates the procedure to odex any apk or jar from the commandline to potentially improve performance. Dalvik runtime (KitKat and below) only. Also uses cut from busybox.
    • N5X/6P BLOD Workaround Injector (N5X, N6P) - link
      When, unfortunately, my Nexus 5X was recently stricken with the abominable Bootloop of Death, I looked into the well-publicized workaround and turns out it was all contained in the ramdisk and cmdline of a Android image. This is the perfect application of AnyKernel2, so I made an AK2 add-on zip to patch both the current boot and recovery partitions with all the current workarounds to help others afflicted by this issue to hopefully regain their data/device as easily as possible. Linked is the Nexus 5X thread, the Nexus 6P thread may be found here.
    • GN Synapse Support Injector (GN) - link
      This AK2 kernel add-on for the Galaxy Nexus injects support for the Synapse tweaking app into the current boot partition ramdisk, including all the Synapse interfaces for the GN I've maintained since the Franco Kernel and DirtyV Kernel days.
    • GN Recovery Color Correction Injector (GN) - link
      The aging screen on the Galaxy Nexus was looking pretty rough in recovery until I discovered the recently added new OMAP kernel color correction was also present in the most recent TWRP recovery versions. So this add-on zip uses AK2 to patch the current recovery partition ramdisk to add the command to reduce that green/yellow SAMOLED nastiness.
    • Kernel init.d Support Injector (many devices) - attached
      An experimental proof-of-concept. Following from great ideas by Captain_Throwback in my AnyKernel2 thread and using script from my Flashlt script above, this AK2 zip will inject basic init.d bootscript support into any kernel ramdisk on any emmc device with normal partition naming and using the Android bootable image standard, without having to bloat a ramdisk using a busybox binary. This zip is also signed, so could potentially be used with non-Nexus stock recovery on a locked bootloader.
    • CMSetup Fix for GApps Installer (many devices) - attached
      Installs a su.d script fix to work around the CyanogenMod/LineageOS 13 ROM issue of a broken Quick Settings pull-down when CMSetupWizard is removed as part of a GApps installation. Removing CMSetupWizard is useful because it allows Google's SetupWizard to grant apps default permissions, so the workaround automatically executes the only required command at the appropriate time following first boot. Requires a SuperSU/Magisk installation (for su.d/post-fs-data.d support). Flash after the SuperSU/Magisk zip and your GApps.
    • Dev Team init.d Pack Installer (all devices) [see "950iosettings, etc." below] - link
      A simple installer I wrote to create the /system/etc/init.d/ directory, extract the latest init.d scripts as published by the "Franco's Dev Team" tuning collective (of which I was a member), then set correct owner, group and permissions to the entire init.d directory. If you are a developer and would like to include these tunables/scripts in your kernel or ROM please provide credit. A lot of time and effort has gone into this project and that's all we ask.

    Scripts
    • 950iosettings + 875mntsettings + 925vmsettings + 975experimental init.d scripts (all devices) [with Franco's Dev Team] - links
      Also available bundled in an installer. The scheduler tunables have already gained a bit of attention/adoption on various devices and kernels, but this is the init.d script I wrote to set the new custom scheduler tunables values as "default" by an independent loop, sleeping in the background and detecting each time the scheduler is changed. There is no effect on idle drain or deep sleep. The settings included are the complete work of the "Franco's Dev Team" (or "Team Franco") tuning collective, of which I was a member. We strove to perfect the scheduler, vm and various other settings for the smoothest and fastest experience available. The collective was: malaroth, osm0sis, joaquinf, The Gingerbread Man, pkgnex, Khrushy, shreddintyres. If you are a developer and would like to include these tunables/scripts in your kernel or ROM please provide credit. A lot of time and effort has gone into this project and that's all we ask. Lollipop(+) updated versions now also available through the continued excellent work of pkgnex.
    • 999-flashafterupdate.sh addon.d+addon.d-v2 script (many devices) - attached
      For ROMs that don't have "Flash After Update" support built into their delta/update process. During an upgrade, this script will flash zips from an sdcard directory, with several options (listed in the script header) for displayed output, after all other addon.d backup/restore actions have completed. This can be used to flash SuperSU and then an AnyKernel2 kernel on LineageOS, for example. Only zips that specifically support addon.d-v2 can be supported on A/B devices. See this how to for instructions for use with A/B devices. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 98-twrp_ab.sh addon.d-v2 script (many devices) - attached
      Allows you to keep TWRP installed in a boot partition through A/B OTAs with Magisk installed by copying the TWRP ramdisk from the current slot to the updated one, before Magisk's addon.d-v2 script patches it. Requires a current Magisk installation since we need the tools and Magisk's the only way to ensure a working addon.d-v2 environment across ROMs at the moment. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 97-dumpbootimage.sh addon.d+addon.d-v2 script (many devices) - attached
      For ROMs with boot.img inside an OTA payload.bin or otherwise inaccessible, it dumps the updated boot partition before further modifications (TWRP, Magisk, etc.), saving it to /sdcard/Download/boot.img or to/from other customizable locations at the top of the script. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 00-omnirootfix.sh addon.d-v2 scipt (many devices) - attached
      OmniROM appears to include 69-gapps.sh automatically in its /system/addon.d directory despite not shipping with any GApps; when not rooted this doesn't appear to present a problem, but really this is only because the script doesn't have enough permissions to run how it's supposed to since Omni's sepolicy doesn't let addon.d-v2 work correctly. Once Magisk is installed, providing more privileges to the addon.d-v2 update_engine, Omni's 69-gapps.sh would remove important system files during an A/B OTA when no GApps were installed, so this script will simply prevent that for those wanting to run Omni minimally and with root. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 00-resizesystem.sh addon.d script (many devices) - attached
      One common solution for aging devices is to resize the /system partition so that it can hold newer, larger ROMs and, of course, GApps packages. On devices where the /system partition has been resized to hold larger GApps packages, but the ROM in use has system.dat format zips with no resizing functionality, the extra space would get lost in a ROM delta flash, breaking things when GApps attempted to restore. This script will resize the system partition to its maximum before the GApps restore occurs on EMMC-based devices with standard partition naming. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 10-extract-lineage-kernel.sh addon.d script (many devices) - attached
      Nowadays with systemless root and other boot.img mods out there, it's good to have a backup of your ROM's unmodified boot.img handy in case you want to do a clean flash of your boot partition. Since LineageOS moved their update zips to a /data/data subdirectory that made this harder to get to, I automated the procedure as an addon.d script so that the newest gets extracted on each update. The output directory may be changed by editing the script. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions.
    • 999-customkernel.sh addon.d script (many devices) - attached
      Addon.d is awesome at restoring your GApps, root app, and other things after a ROM Delta, update, or dirty flash, but of course this can leave a lot of stuff out that you'd also have to re-flash (see below for a personal addon.d script you can modify to cover anything else you want to save). This script aims to help remedy the issue for custom kernel users on EMMC-based devices with standard partition naming by dumping the current kernel as part of the addon.d backup process, and then restoring it after the ROM has flashed its included kernel. Remove the .txt extension once downloaded and place in /system/addon.d/ with rwxr-xr-x (755) permissions. This is deprecated by my FlashAfterUpdate addon.d script, above.
    • logohack.sh (GN) - link
      Galaxy Nexus bootloader image replacement hack script. Inspired by bitdomo's brilliant imgdata tool and replicating the functionality of Ezekeel's abandoned, broken paid Logo Me app, this script improves upon the app version by working on all Galaxy Nexus bootloaders and on-the-fly, to allow replacement of the Google logo and lock images within the sbl partition. Remove the .txt extension once downloaded and place in /system/bin/ or /su/bin/ with rwxr-xr-x (755) permissions. It can then be run from the Terminal.
    • flash_image (many devices) - attached
      MTD devices require a little extra finesse when flashing partitions from the command prompt and multiple commands, versus MMC devices, for which we can just use the dd command both ways. I wrote this little script to simplify the process for myself in my MX Box tinkering. It parses /proc/mtd so you only need to enter the partition name. It requires _n0p_'s excellent MTD-Utils compiled for Android, and uses grep and cut from busybox. Remove the .txt extension once downloaded and place in /system/xbin/ with rwxr-xr-x (755) permissions. It can then be run from the Terminal.
    • getprio (all devices) - attached
      Android doesn't allow you to check the priority (or "niceness") of a process with the getpriority command as you would with normal Linux, and busybox doesn't provide this functionality either, so I wrote this reasonably simple script to allow you to check the niceness of a process. Some kernels have been experimenting with increasing the priority of com.android.systemui for smoothness, so this command can be used for testing different levels and whether the renice command set it correctly. Remove the .txt extension once downloaded and place in /system/xbin/ with rwxr-xr-x (755) permissions. It can then be run from Terminal with either the pid (default), class or a class name search string. Uses pidof and pgrep from busybox.
    • gappsintegrator init.d script (many devices) - link
      ROM GApps Auto-Integration of /data/app GApps into /system, complete with libs (unlike Titanium Backup), for Jelly Bean through Marshmallow. It should process things early enough in the boot that afterwards Dalvik will immediately do the cleanup ("Android is upgrading..."), much like following an OTA. An initial GApps installation is one requirement and there are some important notes for support of Lollipop and above. Intended for ROMs with a busybox installation. Can also remove libs from and zipalign the integrated APKs if those binaries are present in the ROM.
    • lmkwhitelist init.d script (all devices) - link
      Users running ROMs or kernels with extremely aggressive custom lowmemorykiller (lmk) driver settings may notice their launcher redrawing frequently. Some kernels/ROMs also include an exclusion for this by making stock (or the included) launcher unkillable, however that still leaves all the 3rd party launchers out there that people use. I wrote this init.d script with a community created list of the most common launchers to make whichever one is installed unkillable. This also has instructions for how to set up init.d scripts. If your launcher isn't included in the list, you can modifiy it by adding the application class name (from the Play Store URL) to the list within quotes, separated by spaces. Also part of the 975experimental Franco's Dev Team init.d script, linked above.
    • dalvik2cache init.d script (all devices) - link
      Bind mounts the dalvik-cache directory to the cache partition. Useful on devices where the cache is sizable and unlikely to be used for OTAs (custom ROM, etc.), and the data partition is not. Every little bit counts!
    • settingsdump.sh (all devices) - attached
      In comparing vm settings from various kernels and ROMs to see what's out there, I wrote this script to generate a list of the values of all the relevant sysfs files and directories. Now expanded to cover cpu and governor as well. Remove the .txt extension once downloaded. To run it, assuming you just put it in /sdcard/, open Terminal Emulator and type: "sh /sdcard/settingsdump.sh" (without quotes). It will output the file to /sdcard/r*-output.txt where * is the revision of the kernel you're running. This makes it easier to compare what's changed between different nightlies, for example.

The main thread remains locked and can be subscribed-to for those wanting notification only when there's a new GApps release, and the Q&A functioned as the main discussion thread where people can help each other. Much of the script is the same from PA GApps but TKruzze has added some impressive new features, made many fixes and revamped a large portion of the documentation. I also continued as an adviser and submitted script when needed.
    • Nexus Louder Audio Improvement Patch (GN, N4, N5, N7 '12, N7 '13) [with Misledz] - link
      One of my earliest forays into EDIFY scripting, I wrote the flashable zip install/revert scheme for this great volume boost mod by Misledz. The scripts check to see if the mod is already installed and if so recommends you flash the version-specific revert that goes with it. More on that in the Intelligent EDIFY thread. During install the script also backs up the ROM files it replaces so that you don't need to reflash your whole ROM if something goes wrong, just use the revert to restore the backups. I eventually rewrote this completely in shell script with a Universal install/revert, that detects which files to backup and leaves a list for itself to revert. I also wrote automation batch scripts for Misledz as the "Louder Build Farm" to simplify his work for all the versions of the mod he maintains for various devices, linked in the knowledge base below.

    AOSP's BootSignature.jar for AVB v1 was relatively simple to run on-device for boot.img modifying flashable zips like SuperSU and AnyKernel2 but avbtool for AVB v2 is written in Python, so that makes things a bit trickier.

    New addition to the OP. ;)

    Busybox Installer:
    As a byproduct of building my own static busybox compiles in all supported Android architectures for my latest AIK-mobile v2.0 package I figured I might as well offer them up separately as well since there aren't any providers making Android x64 builds, at least not for all of them when I went hunting (to try and save myself some time). The installer detects what architecture (ARM/ARM64, x86/x86_64, MIPS/MIPS64) your device uses and installs the correct busybox binary to /system/xbin accordingly; it detects and supports "systemless" root installation as well, installing to /su/(x)bin instead. It then cleans up any symlinks from a possible previous installation at that location and cleverly generates new symlinks directly from the output of the installed binary, so they always match.

    My busybox configs and patches are available here: https://github.com/osm0sis/android-busybox-ndk

    I've got a patch submitted to the official busybox mailinglist to resolve some API 21 compatibility, so that will probably be added in a future version to save people time and make it easier for more providers. Anyway, hopefully I got all the applets most people want working. :good:


    Edit: Now the zip will also clean up an installation made to /su/bin and then install to /su/xbin. :good: :)

    Edit 2: New special zip features
    You may add keywords to zip filename or in a file at /data/.busybox-ndk:
    1) system or System or SYSTEM to force a system installation.
    2) uninstall or Uninstall or UNINSTALL to uninstall busybox from the zip's detected target location (/su/xbin > /magisk/busybox-ndk/system/xbin > /data/adb/su/xbin > /data/adb/modules/busybox-ndk/system/xbin > /system/xbin, unless system forced per above).
    3) nolinks or NoLinks or NOLINKS to opt out of symlink creation and only push the busybox binary.

    For those curious, I automate bundling my busybox binaries directly with builds from my AIK Build Farm using the following script.

    Bash:
    # also this

    Here we go again!

    Gotta say, I'm pretty gobsmacked at the 16,252 downloads of my busybox zip in the last month and a half (and that's not counting via Magisk), the 20,966 downloads of my sdcard Fix Permissions script zip and then there's the 158,506 downloads of unSU! :cyclops:

    Thanks for the continued support all! I guess I should sit down and figure out how to write an app or something, huh? ;)

    I work on these projects in my limited time off, so if you like the progress I'm making, or enjoy anything else I've done on xda, please do hit the donate link from my profile. Thanks for your support!

    AnyKernel2 has also seen some improvements in the last few weeks, and GN Synapse Injector AK2 zip has been updated accordingly. If your custom kernel of choice uses an AK2 zip or you have ever enjoyed a kernel packaged with it then please go thank my AnyKernel2 thread OP, it's still not even on my member profile's Most Thanked threads, despite being my most known project. :):good:
