Seems like you have a problem with rooting the latest Nougat beta (without wipe), not with DevBase itself. Please try to solve rooting/bootloop problems in SuperSU's thread and then flash systemless DevBase if you still want to. I'm sorry, I have no other ideas :highfive:

Hi,

It seems to be a problem with TWRP without wipe - I already posted in their thread but nobody answered yet.
I also tried some more times to install it and always the same problem - so I'd have 2 questions:

1.: Did you also OTA from BTU (MM) or did you flash Nougat Beta 1 and did an OTA to ZPLN? (well same result if I flash Beta 1 and OTA to Beta 5 and flash TWRP)
2.: Will I be able to get OTA if I factory reset, flash TWRP without booting to system and flashing root + devbase or does it have the same effect like enabling modifications at startup of TWRP?

Regards,
Nestade

1. To be honest I have flashed latest "dumped" Nougat beta. Personally I'm not in "beta program" so can't perform OTA in my phone :(

"Supposedly" it was 100% clean, but just noticed it isn't...

If you are 100% sure that you never swiped "Allow system modifications" in TWRP in your current system and never remounted it rw (*) - you can help me to re-produce your issue with rooting latest nougat beta (and find a workaround, if possible).

(*) you can check if you have untouched /system partition by re-flashing ZPLN Stock recovery (from HERE). Flash it, then enter it and see if there is "dm-verity error..." message (or not) at the bottom.

If you do NOT have such error message then GREAT :) please provide me exact dump of your /system partition (use Terminal Emulator from Play Store):

Code:
su
dd bs=4096 if=/dev/block/sda14 of=/data/media/0/system.img

Copy above file to your PC (it will be located in internal memory -> AKA emulated sdcard). Copy also your original (backed up by SuperSU installer) stock kernel - you can find it in both places - /cache and /data (it is named "stock_boot_****.tar.gz, where **** is SHA1 sum). Compress all files using zip or 7zip and give me DL link, please :)

2. Probably your device will not be able to boot (without wipe) if you unroot non-encrypted device but I'm not 100% sure (I never decrypted my /data @ G935F, yet...)

I just tested your dump by flashing it into my phone (via TWRP's Terminal from OTG storage, due to encrypted /data not available under TWRP):

Code:
dd bs=4096 if=/usb-otg/system.img of=/dev/block/sda14
(I used system.img sent by you)

dd bs=4096 if=/usb-otg/boot.img of=/dev/block/sda5
(I used stock kernel image extracted from your attached backup)

dd bs=4096 if=/usb-otg/recovery.img of=/dev/block/sda6
(I used stock ZPLN recovery which I have, as you know)

Phone booted fine without root, with "Official" status, with all my apps and data (these are still encrypted, of course!). In stock recovery there is NO "dm-verity error..." message, finally! :D so it is exact same as yours (verified by recovery) stock ROM

My exact next steps:
- Flashed TWRP 3.0.2.4 via PC Odin and went directly to it (tap "keep read only", of course)
- Flashed SuperSU 2.79 SR2 ZIP (from OTG storage, due to encrypted /data not available under TWRP)
- Tap "Reboot System"

Phone booted fine WITH working root, with "Custom" status, with all my apps and data (remained encrypted, of course! There is no access from TWRP)


In sum - I still can't explain your problem with rooting latest beta.. I'm sorry

Hi,

Well - it's no problem.
By the way - I received the OTA to official Nougat Release.

OT: How can I extract the whole firmware to provide it to other users? (BL, AP, CSC, CP)

Issue with rooting encrypted ZPLN and DPLT confirmed :(

Warning has been added in #1

Let's hope @Chainfire will find a solution soon...
tks for ur warning, i couldn't wait to get my hand on the official nougat update. i've been using ur rom for months and nothing to complain about, battery life is great, phone is surprisingly smooth and fast performance-wise, i don't use xposed or magisk though. i don't even have a single crash since day one. ur approach is just unique, and i love that systemless idea. ur rom simply the best ive ever used since galaxy s5.

In my opinion it's caused by TWRP as it also appears if I only flash TWRP, "Keep read only" and reboot.

You're right... Just tested it - same here..

I skipped this important scenario and draw wrong conclusions ;) WARNING has been edited:

Before:
(!) WARNING (related to rooting latest Nougat - e.g. ZPLN, DPLT): There are confirmed reports that installing SuperSU on encrypted phones causes bootloop. It is not just ordinary bootloop - phone will not be able to boot even if you restore stock boot image! You will need to wipe data to make your device bootable (losing all encrypted data, by the way)! Let's hope @Chainfire will find a solution soon.

After:
(!) WARNING (related to installing TWRP @ Nougat - e.g. ZPLN, DPLT): There are confirmed reports that entering TWRP on encrypted phones running Nougat causes bootloop (even if you just enter TWRP, tap "Keep read only", do nothing else and then tap reboot!). You will need to restore both - stock recovery and stock kernel (if you e.g. tried to flash SuperSU or other ZIP which might modify the kernel) to make your device bootable. In case of encrypted devices we need to wait for a solution..

I temporarily can't perform any physical tests as I broke display in my S7 edge :crying: I sold it for spare parts due to high price of screen replacement in the authorized Samsung service...

I'm going to buy next S7 as soon as possible but I'm not going to root it immediately (I need to test it some time to exclude hidden defects)

Hi,

Is it still possible to flash the files manually with flashfire?
If yes, will I lose my app-settings etc./root/devbase?

v0.55 shouldd work well with nougat (see changelog in #8):
https://forum.xda-developers.com/general/paid-software/flashfire-t3075433

i upgraded to nougat today with decrypted data and supersu 2.79, however i couldn't flash the dev-base file, it gave me "required files not found" on both csc and safe debloat feature. any idea?

I can't re-produce issue due to above "sad introduction" ... ;)

Does this issue occur in both - TWRP and FlashFire?

EDIT: Check if you have physically required files, e.g. /system/csc/others.xml. I suppose that you flashed firmware via odin and then went to DM immediately after ROM flashing (WITHOUT performing all action from /cache by stock recovery). If I'm right - files in /system/csc/* really not exists (then it is NOT DevBase issue)

edit: pls disregard, you're right, i overlooked one of the step you mentioned above, i didn't boot the phone after wiping the data, hence the problem occur, all goods now :)

its sad to know u broke your phone. fyu, i flashed the firmware using odin, boot the phone normally, all bloatware are installed, i then installed the dev-base and got that error. reboot the phone and all bloatware still appear.

guys, been running dev-base with nougat for almost 3 days, it's been working flawlessly for me so far. since i enabled google assistant through build.prop and have fitbit app installed in favour of shealth, i found no need of svoice, sheath services and shealth app. i'd like to remove those. is it safe to do so? would it cause any prob with stock rom?

Shealth works fine on a rooted phone. Just update following strings in build.prop

ro.config.knox=0
ro.config.tima=0

thank you, but i think you misread my question. i meant to remove those apps, i don't wanna use shealth and svoice, based on @_alexndr suggestion from here. i'm wondering if there is any side-effects if i disable those apps, because it's known to deeply integrated into touchwiz

Yeah I got what you mean. But I guess after making any change in system you would lose the systemless feature and might not receiving OTA. Instead you can add all your unwanted apps in enforceskippingpackages.txt of the devbase.

    Hello :)

    Do you remember my custom ROMs for older devices? Do you remember my "DevBase" and its idea? If not - please read hidden content below:

    >> [ROM] DevBase for Note 3 (SM-N9005) <<
    >> [ROM] DevBase for Note 4 (SM-N910F) <<
    >> [ROM] DevBase for S5 (SM-G900F) <<
    >> [ROM] DevBase for S5 Duos (SM-G900FD) <<

    Since I created these custom ROMs - many things have changed. Main idea of my previous work was the ability to flash these ROMs over stock ROM without wipe data - to let users simply jump between official ROM and DevBase with most necessary modifications for advanced users. It was relatively simple to implement until Samsung introduced both: dm-verity's boot prevention + forced /data encryption (starting from S7/S7edge series). What does it mean? If you disable /data encryption - you are able to use TWRP like in older devices, you are able to flash custom ROMs available in this section, but you are not able simply switch to official stock ROM. Since I bought my S7 edge I realized, that the most reasonable way is to go in the "systemless direction".

    Are you tired with traditional custom ROMs?

    Do you miss custom ROMs but do not want to decrypt your device (for privacy/security reasons)? (!)

    You are in the right place! :cool: I present you SYSTEMLESS DevBase - an SYSTEMLESS equivalent of my previous work (see hidden content above) :cool:

    SYSTEMLESS DevBase is developed and physically tested on S7 Edge (G935F). However, it should work on ALL UNLOCKED SAMSUNG DEVICES running Android 6.x/7.x/8.x. Exynos? Snapdragon? NO MATTER !!! :cool:


    Prerequisites:
    - Samsung device running stock or stock-based Android 6.x or newer (7.x/8.x)
    - Rooted device - Magisk v12+ or SuperSU v2.76+ installed in SYSTEMLESS mode (!)
    - Stock, untouched /system partition (not mandatory, but recommended for OTA)

    (!) WARNING (related to installing TWRP and/or rooting Nougat - e.g. ZPLN, DPLT or newer): There are confirmed reports that installing TWRP and/or rooting encrypted phones running stock Nougat causes bootloop (even if you just flash TWRP, without rooting). You will need to restore both - stock recovery and stock kernel (if you e.g. tried to flash SuperSU or other ZIP which might modify the kernel) to make your device bootable. You need to remove stock encryption (by formatting /data after rooting). If you need data encryption - you can easy re-encrypt already rooted device (by setting "KEEPFORCEENCRYPT" flag to "true" before (re)flashing Magisk or SuperSU).


    SYSTEMLESS DevBase v2.0:

    1. Benefits / main features:
    - Works with encypted /data partition (**) (!)
    - Working official OTA updates! (see Tips & Tricks - post #4)
    - Does NOT perform any phisical modifications in /system
    - Does NOT perform any additional changes/patches to the kernel
    - Removed KNOX warnings (systemlessly removed SecurityLogAgent)
    - It contains SYSTEMLESS BusyBox (bionic, the most stable and respected release)
    - It allows you to easily modify most of files & apps in your /system - SYSTEMLESSLY (see Tips & Tricks)

    2. Systemless Safe De-Bloat (more info below):

    What does it mean and why is it called "safe"?

    - ONLY apps available in stores will be systemlessly removed from the ROM, so you can easily (re)install any of these app if you like
    - ONLY pre-installed system apps are will be systemlessly removed, DevBase installer never touch any updated app nor app installed manually from store

    Thus, the following conclusions can be drawn:

    1. If you install my SYSTEMLESS DevBase directly over working stock ROM - in most cases almost all these apps will remain untouched, because almost all apps have been updated already (stored on /data). But then you will be able to remove any useless app using the "Application manager" -> [Name_Of_App_To_Remove] -> MORE -> Uninstall updates. NOTE: App will disappear arter reboot and will be visible even in Titanium Backup! :cool:

    2. If you perform "Wipe data" directly before installing SuperSU and my SYSTEMLESS DevBase (before you let to install app's updates) - then all apps listed below will be removed. If you would like to use any of these apps - just install it manually from appropriate store. Installed manually app will not be removed during the next DevBase update or re-install.

    Removed apps list (depends on the device, should cover all devices starting from Galaxy S5):

    ChatON
    Chrome
    Drive
    Dropbox
    EditorsDocs
    Evernote
    Excel
    Facebook
    FB Messenger
    FB Pages Manager
    Flipboard
    Google+ / Photos
    Group Play
    Hangouts
    Instagram
    OneDrive
    OneNote
    PEN.UP
    Play Books
    Play Games
    Play Movies
    Play Music
    Play Newsstand
    PowerPoint
    Skype
    Smart Remote
    WhatsApp
    Word


    NEW! Safe De-Bloat feature automatically detects and systemlessly removes apps not listed above, but present in your CSC package :cool:

    3. Systemless CscFeature MOD (enabled some built-in, hidden features):
    - Added shutter sound menu in Camera app
    - Sending/receiving MMS without data on
    - Show SMS/MMS sending time instead of receiving
    - Added "Exit Internet" option to stock browser
    - Added call button in Phone Logs (**)
    - Added "Call/Message block" option in Settings
    - Added symbols as secondary keys in Samsung keyboard (**)
    - Added 4G/3G network support (master/slave SIM card - applies to Duos variants)
    - Call Recording (added "Record" button, auto record calls - starting from Nougat)
    - Enabled "Recent App Protection" feature

    (**) may not work starting from Android 7.0 Nougat


    Installation:

    1. TWRP recovery:
    - Tap "Keep Read Only" on the Welcome screen [extremely important for working OTA!]
    - Open file using "Install" option (use extSdCard or OTG storage in case of encrypted /data)
    - Confirm flash by swiping right
    - Tap "Reboot System" (DO NOT wipe /cache after flashing in case of encrypted /data!)

    2. FlashFire app (***):
    - Open file using "Flash ZIP or OTA" option
    - UNTICK "Mount /system read/write" [extremely important for working OTA!]
    - Tap "FLASH"

    NOTE1: One additional auto-reboot may be performed at first boot. It is not a bug (may be required for systemless build.prop support - see Tips & Tricks for more explanations)
    NOTE2: Do not worry about red "mount /data failed..." messages displayed in TWRP in case of encrypted /data (installer will do the work anyway!)

    (***) As far as I know - FlashFire is the only flashing tool with full access to /data during flash in case of encrypted devices (!). It is also the only tool which allows you to perform full backup/restore of partitions, including encrypted /data (!). It does NOT require custom recovery to work!

    Note:
    Check MD5 sum BEFORE flash (useful TOOL), because flashing damaged or incomplete ZIP files can lead to issues! Correct MD5 sum is shown on the AndroidFileHost website while downloading.

    Tips & Tricks

    1. OTA updates:

    - Basically, the only thing you need to take OTA update is to perform "Full unroot" in the SuperSU app. However, a better way is to use "unroot2ota" terminal command, because this will not remove DevBase boot script from /su/su.d and the only thing you will need to re-activate SYSTEMLESS DevBase (and all your systemless MODs) after performing OTA update is just re-root your device with CF-Auto-Root.
    - If you flashed custom recovery like TWRP - it is mandatory to restore your stock recovery (otherwise OTA will not work). You can do it using FlashFire app (the easiest way) - just open recovery.img file (extracted from your original FW) using "Flash firmware package" option, disable "Preserve recovery" option and then tap "FLASH". EDIT: Starting from version v1.2 there is a new "unroot2ota" feature which allow you to restore stock recovery using /system/recovery-fromm-boot.p file. There is no guarantee to perform it successfully (even if there is no error message) but in most cases it works well (tested on Nougat beta). Please go to recovery before you try to get OTA to check if you have stock recovery already after performing "unroot2ota" (if not - you need to use PC Odin to flash recovery.img packed in tar file).
    - It is recommended to temporarily disable "Auto-update apps" in Play Store settings before you unroot your device. It will prevent updating applications covered by Safe De-Bloat list, as there apps will temporarily appear until you re-root the phone after performing OTA update.

    Note (devices which use dm-verity): You should never allow /system modifications in TWRP, never allow to remount /system r/w in any app (e.g. Root Explorer, FlashFire, etc.) and never flash a ZIP file which could modify your /system or remount it r/w. Failure to follow these recommendations will break dm-verity verification and will cause, that your device may not be able to boot with the stock kernel (you will need to re-flash your original FW using PC Odin to make your device bootable).

    UPDATE: Due to the fact that installing TWRP and/or rooting encrypted phones running stock Nougat is not possible without format /data - the above described advantages applies to stock ROMs based on Android up to 6.0 :(

    2. Making your own modifications:

    - You can systemlessly replace any existing system app by modded one. Just put modified app to /data/devbase/system/app or /data/devbase/system/priv-app and then reboot your device
    - You can systemlessly replace jar or apk in /system/framework. Just put modified one to /data/devbase/system/framework and then reboot your device (NOTE: framework support has been added for advanced users -> there is high risk of bootloop if you do something wrong!)
    - You can systemlessly add or override any line in /system/build.prop. Just put (only new or changed) line to /data/devbase/system/build.prop and then reboot your device (NOTE: one additional auto-reboot may be performed if /data/devbase/system/build.prop file has been added, modified or removed (SuperSU case). It is not a bug - it is required for the changes in /data/devbase/system/build.prop to take effect!)
    - You can systemlessly replace any existing file in /system/csc and /system/etc (but NOT in subdirectories). Just put modified copy of a file to /data/devbase/system/csc or /data/devbase/system/etc and then reboot device

    Limitations: original app or file MUST physically exist with the same name in /system, you can NOT add a new app or file this way!

    Example 1 (Ad-Blocking): Download the latest Ad-Blocking ZIP installer from THIS thread. Extract "hosts" file (placed in /system/etc inside ZIP file), then copy it to /data/devbase/system/etc, set rw-r--r-- (644) permissions and then reboot device

    Example 2 (modded SamsungCamera6): Create "SamsungCamera6" directory in /data/devbase/system/priv-app and then put modified "SamsungCamera6.apk" file into it. Set rwxr-xr-x (755) permissions to "SamsungCamera6" directory, rw-r--r-- (644) permissions to "SamsungCamera6.apk" and then reboot device

    Example 3 (De-Bloating a bit more): You can just create empty directories in /data/devbase/system/app (or priv-app) corresponding to applications in /system/app (or priv-app). Alternatively (more advanced method), you can add an app to modded enforceskippingpackages.txt file (you can find it in /data/devbase/system/etc or /data/devbase/system/csc_contents, depending on the original location in /system) and increase number in the 1st line. Second method should not be used by beginners (without a basic knowledge related to UNIX text format)

    3. How to manually maintain the newest ROM version:

    If you do not care about OTA - you can manually update your device to the newest ROM available @ Sammobile, keeping your original CSC (you need multi-file original FW, I mean separate files for BL/AP/CP/CSC). You need to download 2 ROMs: ROM with the newest changelist and the latest ROM containing your original CSC. Extract both and open in PC Odin BL/AP/CP files from the ROM with highest changelist but open CSC file from the ROM containing your CSC (I recommend to use HOME_CSC_* file to avoid auto-wipe-data). Flash such "mix", re-root and enjoy :cool:

    Optional MODs

    I put some of my favorite MOD's. These modifications I have done personally using (bak)smali tools - these are NOT "borrowed" from other custom rom, nor from someone else's thread (thanks to @majdinj & @tdunham for their excellent modding guides). All files are FlashFire / TWRP flashable ZIPs.

    These MODs are compatible with SYSTEMLESS DevBase - installer will try to detect if your /system has been moddified (or not) already. If the installer will not detect any popular /system modifications like SuperSU / busybox / Xposed (installed to /system) then will try to install app systemlessly to /data/devbase/system/(priv-)app

    1. Modified Camera app:
    - Full functionality of the Camera app in low battery

    2. Modified Messages app:
    - Disabled SMS delivery notifications (*)

    (*) If you long press a message you can still check if the message has been delivered or not, we do not need to see and hear notifications for every sms. It's annoying to me!

    >> MODs for G935F (Marshmallow) << (**)

    >> MODs for G935F (Nougat) << (**)

    (**) Original apps come from stock ROM for G935F, but these MODs should work on all S7 flat & edge variants (Exynos based) :)

    In case of MODs installed to /system - you can restore original apk using backup stored in /data/alexndr/backup

    Changelog

    v2.1:
    - Fixed potential "Google Play services" FCs in case of S8 or newer device(s)

    v2.0:
    - Initial support for devices using /system/omc CSC location (e.g. S8 / S8+ / Note 8)
    - Added support for /system/preload as app location
    - Other improvements & optimizations in the installer

    v1.15:
    - Added support for BINDSBIN mode (required by latest suhide) in case of SuperSU as root solution

    v1.14:
    - Added possibility to bypass all systemless mods by creating /cache/.disable_devbase file. It is usefull option especially for encrypted devices (without access to /data from TWRP) in case of you experienced bootloop due to placing a problematic MOD in /data/devbase/system/.. If /cache/.disable_devbase file exists then all systemless mods in ../app ../framework & ../piv-app will be moved to /data/devbase/system/.backup
    - Backup all mods (to /data/devbase/system/.backup) instead of delete in case of major Android update has been detected

    v1.13:
    - Fixed bug with combination Magisk v15+ & SYSTEMLESS DevBase if we are trying to install one by one directly after wipe/format data

    v1.12:
    - Improved compatibility with Magisk v15+

    v1.11:
    - Fixed issues and improved compatibility with Magisk v14.5+

    v1.10:
    - Fixed not working /sbin support after clean installation of Magisk v14+, then SYSTEMLESS DevBase

    v1.9:
    - Improved/tuned compatibility with Magisk v13+ (which has been re-built from the scratch)
    - Updated Magisk's binaries (e.g. resetprop function is now an applet available in magisk binary)
    - Systemless BusyBox will be installed even with Magisk (since it has been removed from Magisk v13+)

    v1.8:
    - Fixed unroot2ota script to work while busybox is NOT in the $PATH (typical Magisk's case)

    v1.7:
    - Added support for /sbin via /data/devbase/sbin (you can only add a NEW item, e.g. script/binary/executable file). It can be an interesting feature for advanced users which would like to add custom commands, because /sbin is in the $PATH
    - resetprop & unroot2ota now are placed in /sbin, in result unroot2ota command will natively work even with Magisk (without SuperSU)

    v1.6:
    - Improved/fixed Systemless Safe De-Bloat - now it should work in any case (even if enforceskippingpackages.txt file does not exist in your stock FW)
    - In case of SYSTEMLESS DevBase update or re-installation - installer will not remove your custom entries in /data/devbase/system/build.prop and in *.xml files placed in /data/devbase/system/csc
    - Added new features to Systemless CscFeature MOD: Allow 3G network mode in case of slave SIM card (Duos variant); Enabled "Recent App Protection" feature

    v1.5:
    - Added full support for MagiskSU as root solution. SuperSU is no longer the only available prerequisite
    - Improved build.prop support in case of SuperSU as root solution, without magisk installed (seems like we can't rely on resetprop binary @ Android N)
