--original uses the ramdisk it split from the .img which is why it's literally identical with no changes. Still not sure why normal repacking doesn't work for your device, obviously something's going on in the ramdisk that not even unpacking/repacking as root on Linux can resolve, which is a new one.

My best suggestion is to look into the build process that created the original ROM .img and see if there's anything extra in there we're missing. If it's only that signing then perhaps the bootloader's more strict than previously on your device and doesn't allow unsigned at all anymore.

Edit: Hey @arter97, I see you build a Note 5 kernel.. Any ideas what we're missing here that's causing a hung boot with a "kernel not seandroid enforcing" message after an unpack+repack with no changes? Thanks for any help you can provide! :)

Hilariously this has been his kernel that we have been trying to take apart the whole time. I reached out to him and another kernel dev with no response. I believe they are afraid of giving information to potential competition. His kernel is amazing and I had no intentions of releasing a rom with his kernel, it was just for personal use.

I was trying to edit a script in the kernel which is building Knox folders on each boot. I wanted to just take one line out of the init.d script to fix it. That's all I was doing.

Being that I am typing this from my brand new nexus 6p I'm not sure how much more energy I will have for the note 5. But I will try to test if possible.

@seh6183, seeing as you had an issue with your flash of --original originally, and were mistaken, can you double check that my root repack (attached on the previous page) actually doesn't work? Thanks in advance.

hi. sorry for replying here as a noob but i have a question
i flashed android 6.0.1 beta rom to my s6 edge... and still there isn't twrp that be compatible with new sboot so is there anyway to edit ramdisk of twrp 2.7.8.1 that is compatibe with my device in android 5.1.1 and old sboot, to be used in 6.0.1 ?

Don't quote the OP. The magic from file can make Linux file binary angry. I thought I'd removed all the troublesome entries since I had it working on my Ubuntu VM..

You're using v2.0?

Okay. Please edit your post to remove the quoted OP.

Then edit AIK-Linux/bin/magic and go to line 1293 and remove the entire "# Android Backup archive # From: Ariel Shkedi" section that line is a part of. Let me know if AIK-Linux/unpackimg.sh executes correctly after.

If you want to do it as root, do: ./unpackimg.sh --sudo boot.img

Bugfix/maintenance releases up! These add support for devices with pre-header data greater than the original arbitrary unpackbootimg seek cutoff of 512KB; I have raised this to a reasonable 4096 which is the highest I've seen on an image. I went ahead and sync'd up everything else to AOSP master and the CM13 branches. :good:

Android Image Kitchen v2.4:
- Update mkbootimg, unpackbootimg and mkbootfs binaries from my repos.
- Update to the latest Cygwin binaries and libraries.
- Fix slimmed magic file (from file 5.25) for certain file binaries.

AIK-mobile v2.1 + AIK-Linux v2.1:
- Update mkbootimg, unpackbootimg and mkbootfs binaries from my repos.
- Update busybox binary (still 1.24.1) with the latest official patches (AIK-mobile).
- Fix mounting/installation and improve systemless root detection/support on CM Simple Recovery (AIK-mobile).
- Fix slimmed magic file (from file 5.25) for certain file binaries.

More on my own build changes in the commits here: https://github.com/osm0sis/mkbootimg; https://github.com/osm0sis/mkbootfs.

Installation information and details on each edition can be found in the OP for Win32 or the AIK-mobile and AIK-Linux initial release notes.


If you are reporting a problem with your device, please clearly state your device name and model/variant as well as provide a link to the image file.

Sorry I reflashed this 2 days ago but forgot to tell you. Still doesn't work sorry. Certainly did not make any mistakes. During the flashing process all readouts display on screen as if nothing is wrong and then it fails to boot.

This tool doesn't compile at all, it only allows you to edit the ramdisk. Since you're using LG G3 my guess is you need to "Bump" the resulting image file before flash. Google that and you'll find the extra tools required.

What little free time I have is pretty much already spoken for with my various projects, so I can't really be taking on everyone else's. Research/test more and ask in the bump thread.

Hi all! Help me please, my phone is HTC 326g, don't work recovery after compiling this tool, even unpack and pack files without changing the tool is still not working. Sorry for my bad english, i'm from Russia.
Всем привет! Не работает recovery на HTC 326g после сборки с помощью данной программы, даже если распаковать и заново запаковать с помощью этой программы всё равно не работает, помогите!

    Well well, it's been a very long while, (roughly the age of a toddler 😛)... let's do things a little differently this time so people can have something hopefully of use until I get all the features and platforms complete... 😉

    Here is the first of likely a number of WIP AIK snapshots I'll do as things progress towards my release checklist. As it is a work in progress, expect some things could change before final, or possible regressions, but that I'm fairly happy with what I've got for the features implemented at this point. 🤠

    It's arm64 AIK-mobile only for now, zipped directly off of the device I'm currently writing it on. The other prerequisite is that you know what you're doing enough to have installed AIK-mobile v3.8 already and can unzip my attached zip over top of it, into /data/local, and know how to help figure things out if something goes wrong in your testing. 🙌

    AIK-mobile v3.9 WIP 20240416:
    - grow ext4 ramdisk.img to 192 MB for unpacking larger ramdisks (AIK-mobile)
    - add latest (1bbcd66) AOSP avbtool.py for AVBv2 signing support (QPython app install required on AIK-mobile)
    - retain and allow modifying important AVBv2 hash footer argument values
    - update loop mount logic to reduce errors (AIK-mobile)
    - update busybox binary (1.36.1) with the latest patches and fixes from my repo (AIK-mobile)
    - support detecting and adding any SEANDROIDENFORCE string before AVBv2 signing

    Lots more to come! 😎

    See the Mobile Edition (AIK-mobile) initial release notes for the specifics on the native Android version.
    Likewise for the Linux/macOS Edition (AIK-Linux) initial release notes.

    My original intent was to have this package dependency-free, but as you can see, I did have to include Cygwin. Initially just for mkbootimg since the huaixzk standalone version wouldn't work (it wasn't loading the kernel as binary, thanks trevd); then I discovered that using the GNUWin32 cpio to unpack somehow didn't play nice with repacking the ramdisk in a usable state, so at that point I decided I might as well go Cygwin across the board. As it is, I've included the latest Cygwin-dependent executables and required libraries from their repos and built my own custom Cygwin image and ramdisk utilities built from the latest sources.

    Originally only for Google Pixel/Nexus/AOSP standard boot.img files, built-in support has now expanded to Google Pixel/AOSP vendor_boot.img files, Android Verified Boot (AVBv1)/ChromeOS/SignBlob signed boot.img files, Barnes & Noble Nook "Green Loader" signed boot.img files, Samsung/Spreadtrum DHTB header signed boot.img files, the Samsung/Marvell PXA1088/1908 board boot.img variant (AOSP-PXA), Loki patched boot.img files, amonet patched boot.img files, Sony SIN signed/packaged kernel.elf extraction, Sony ELF kernel.elf files, Intel OSIP Android image files, DENX U-Boot uImage files, Rockchip KRNL signed ramdisk image files, MTK headers for kernel/ramdisk, and LG Bump/Samsung SEAndroid footers for boot.img.

    The main advantage here is you don't need Cygwin shell or PERL scripts. Other guides exist but none of them are universal for target device, compression and/or developed for Windows, Android ARM/x86/MIPS + ARM64/x86_64/MIPS64, and now macOS. With this universality in mind I've automated the whole process with batch/shell scripts.

    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!


    Instructions

    1)     Unzip.
    2) Either use the command-line "unpackimg <image-filename.img>", or simply drag-and-drop the image. This will split the image and unpack the ramdisk to a subdirectory.
    3) Alter the ramdisk as you like.
    4) The repackimg script requires no input and simply recombines the previously split kernel with the newly packed modified ramdisk using all the original image information (which was also split and saved).
    5) The cleanup script resets the folder to its initial state, removing the split_img+ramdisk directories and any new packed ramdisk or image files.

    There are a few optional, advanced command-line arguments for repackimg: "--original", which will cause it to repack using the original split ramdisk instead of repacking, this is useful for testing or trimming dumps; "--origsize", which will cause it to repack then pad it to the size of the original image, this is useful for repacking dumps to then be fastboot flashed; "--level" with 1-9 and possibly 0 allows changing the compression level used to repack to more closely match the original; "--avbkey" with (optionally path and) a keyname allows changing from the default AOSP verity key; "--forceelf" to attempt to make an older unpacked Sony ELF file repack as an ELF.

    All scripts also allow unpacking/repacking with the current directory instead of the AIK directory if "--local" is the first command-line argument.

    Supported ramdisk compression formats in the *-ramdiskcomp file are gzip, lzop, lzma, xz, bzip2, lz4, lz4-l (for lz4 legacy), cpio (for uncompressed), and empty (for no ramdisk).

    Usage is similar for the Android and Linux versions, again, just review the release notes for them.

    Hopefully this is some help to someone. It's been extremely useful for me in my messing around with kernel ramdisks, which is why I created it in the first place.

    Enjoy!
    Questions, comments and feedback welcome.


    If you are reporting a problem with your device, please clearly state your device name and model/variant, attach a log, as well as provide a link to the image file.

    AIK should be universal for Android devices that accept AOSP, ELF, OSIP, U-Boot and KRNL format images in theory, but there is always a chance it doesn't work for your device due to image packing differences, etc. Here is a running list of confirmed working and questionably/confirmed not working devices. If your device isn't in either list odds are that it will still work fine.

    Confirmed Not Working Devices
    • Blackview BV4000 - some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature. While present on multiple MTK devices, it only appears to be enforced by the bootloader on some. See this post.
    • HTC Desire 326G, Huawei Honor Bee, Huawei MediaPad T1 7.0 - some newer Spreadtrum devices use special image signing that adds a "SPRD-SECUREFLAG" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool. See this post.
    • Nibiru V05-A, Pipo Max - some RockChip (RK) devices use a variant of the AOSP image format with extra checksums and hidden sections with extra data. There is not currently an open source tool that can handle repacking these. See this post.
    • Samsung Galaxy S (Advance, Captivate, Vibrant), Samsung Galaxy S2, Samsung Galaxy Note & Samsung Galaxy Tab - contain zImage (kernel) + ramdisk (possibly within the zImage) but are the "headerless" Linux kernel blob format and require a full cross-compiler to repack correctly. See this post.
    • Samsung [various] - the image and SEANDROIDENFORCE footer are followed by a signature that, while present on many Samsung devices, only appears to be enforced by the bootloader on some. See this post.
    • Skyworth 50G2A TV - some newer MediaTek (MTK) devices use special image part signing that adds a 256-byte checksum/signature to both Image.gz-dtb/zImage-dtb (kernel) and ramdisk.cpio.gz, so images will unpack/repack but most likely won't boot unless run through their internal signing tool. See this post.
    • Xiaomi Mi Box 3S, ZTE B860H STB - some newer Amlogic devices use special image signing that adds an "AMLSECU!" signature within the header and appears to encrypt the ramdisk, so the image itself will unpack/repack but cannot be re-signed, and the ramdisk cannot be unpacked or modified.

    Note: For devices requiring Loki patched images (e.g. LG G2, AT&T Samsung Galaxy S4), your device's aboot.img dump must be in the script directory to Re-Loki. (Thank you to jeboo for the original one-way Lok2Img Workaround's binary source, used prior to the official Loki Tool gaining un-Loki support).

    Android ARM/ARM64, x86/x86_64 + MIPS/MIPS64 version of Android Image Kitchen! Now you can easily modify ramdisks on the go! :D

    AIK-mobile:
    - Almost complete feature parity with the Windows/Linux version, including compression support, --original to repack with the original ramdisk, --origsize to pad the repacked image to the size of the original, --level to change the compression level of the repacked ramdisk, --avbkey to change the key used for Android Verified Boot (AVBv1) signing of the repacked image, and --forceelf to make an older unpacked Sony ELF file repack as an ELF. The only thing missing is --local since AIK-mobile's ability to unpack/repack while booted in Android is too complex to easily allow moving the unpack/repack directory around.
    - The flashable zip installs AIK for your Android architecture (ARM/ARM64, x86/x86_64, MIPS/MIPS64) to /data/local/AIK-mobile/ and a helper script created at /system/xbin/aik (alternately /su/bin/aik or /sbin/supersu/bin/aik if SuperSU systemless root is detected, or, /sbin/.magisk/img/aik-mobile/bin/aik or /data/adb/modules/aik-mobile/bin/aik if Magisk is detected).
    - Type "aik" in Terminal Emulator to automatically go to the install directory and get a root prompt, then use, eg. "unpackimg.sh boot.img" to get started.
    - Running su -c "/data/local/AIK-mobile/bin/aik --restore" will recreate the aik helper script in the appropriate place (see above), e.g. after a ROM flash with su.img SuperSU or magisk.img Magisk removed.
    - "aik --uninstall" should be self-explanatory, and "--help" is also available for all included scripts.

    Now also possible to run entirely from a file explorer app, see this post for details!

    To run from TWRP (recovery shell), follow the instructions in this post.

    Originally all but busybox were compiled natively on my Nexus 7 2013 using a KBox2 build environment, now cross-compiled with the NDK on my PC and my own AIK Build Farm. :cowboy:

    Notes: You may delete /data/local/AIK-mobile/bin/busybox if you want to use your ROM's busybox instead.


    Linux will be next on the list, and should be pretty easy since I did all of the shell script leg work with the Android version. ;) (y)

    Another longtime request. New Linux version of Android Image Kitchen up in the OP! Bringing my updated binaries back home! ;)

    Now also supporting macOS out-of-the-box (i.e. no Homebrew or MacPorts addons needed) with v3.0+!

    AIK-Linux:
    - Complete feature parity with the Windows/Android versions, including compression support, --original to repack with the original ramdisk, --origsize to pad the repacked image to the size of the original, --level to change the compression level of the repacked ramdisk, --avbkey to change the key used for Android Verified Boot signing of the repacked image, and --forceelf to make an older unpacked Sony ELF file repack as an ELF.
    - Unpacks as root by default to maintain full control over all repacked ramdisk file ownership/permissions, --nosudo argument available to attempt unpack/repack as user if possible.
    - All scripts allow unpacking/repacking with the current directory instead of the AIK directory if --local is the first command-line argument.
    - "--help" is also available for all included scripts.
    - Unpack with "tar -xzvf AIK-Linux-*.tar.gz" in your home directory then you can go to AIK-Linux and use, eg. "./unpackimg.sh boot.img" to get started.

    Most included binaries were compiled using my patched crosstool-ng i686 and x86_64 Cygwin to Linux cross-compiler toolchains, now as part of my own AIK Build Farm. :cowboy:

    macOS compiles built with osxcross. Instructions available via my Build Farm post.

    I'm not going to interfere with anyone's Linux installations, nor needlessly bundle a ton of commonly available binaries, so if you need extra compression support you need to have those packages installed. In my Ubuntu Server VM gzip, bzip2 and xz/lzma all seem to come pretty much by default, and "apt-get install lzop bsdmainutils" handles lzop and hexdump. Java depends on your setup, but openjdk-8-jre will be what most will want if not already included. lz4 would be the only one that would have to be built from source on many distros, so I have considered it an exception, built it and included it myself.

    Thanks to shoey63 and talich for testing. Cheers! :)

    It's been a busy few weeks!

    After a Herculean effort to get the DENX U-Boot utilities to build with the NDK, which required me firing up my Ubuntu VM (for more than testing for once) and then hacking both the NDK toolchains and tool sources, say hello to U-Boot support! It's a *nix standard, and pretty rare on Android but it does exist (e.g. LG Optimus 3D) and I'm extremely pleased to add support for this completely different type of image format to AIK! :cowboy:

    I then added support for the Samsung/Marvell variant of the AOSP standard for their pxa1088 board, which I've termed "AOSP-PXA", by updating a modified bootimg tools fork to continue the excellent work done by @ketut.kumajaya and @akuhak. There aren't a lot of known examples of these either (e.g. Samsung Galaxy Core Mini 4G, Samsung Galaxy Tab 4 7.0 & Samsung Galaxy Xcover 3) but it was pretty straightforward and removes another entry from the "Confirmed Not Working" list in the OPs. ;)

    Next up, Sony SIN packaging/signature unpack support, thanks to the brilliant research and development of @munjeni for his closed-source kernel_dump binary, of which he also supplied the builds.

    Last but not least, it turns out the signatures I identified on the Pixels last month almost immediately went into enforcement after my release.. and it turns out we misunderstood the nature of these signatures so I have reverted the unpackbootimg patch that was originally submitted to me for the Xioami Mi MAX where these signatures were first found; while reappending the original signature was reported to have worked for the Mi MAX, the Pixel bootloader appears to be enforcing it even more strictly and so they must be signed correctly. Luckily, thanks to the great and ongoing work of @Chainfire we've got a cross-platform working signing tool, but it does rely on a Java-like VM - Java Runtime Environment (JRE) 8+ for Windows/Linux to run correctly - and we can use the Dalvik VM on Android without any issues drawing in part from my previous experiments in this area.

    Since the original AVB signing OEM keys are naturally unavailable this presents a bit of a problem and there are numerous keys already floating around including SuperSU, ElementalX and a few custom Pixel ROMs. To be sensible we the modding community should all try to use the same keys for interoperability, to make sure different mods stack correctly and avoid any possible problems with encrypted devices, so I have generated the required extra certificate for AVB signing from the usual AOSP testkeys and would encourage all other boot image modifying projects to use them; they are available for use on my GitHub. They are the default for AIK, but a user may specify --avbkey on the repackimg commandline to force the use of other keys. The keys may be placed in the main AIK directory and specified without path with only the base name of the files (e.g. --avbkey supersu for supersu.pk8 and supersu.x509.der) or with a path, but still omitting the file extensions to keep it simple (e.g. --avbkey /path/to/ex for /path/to/ex.pk8 and /path/to/ex.x509.der). Hopefully that'll cover all the bases and some other projects will come around to using the testkeys.

    Per usual, the AIK Build Farm has been updated accordingly. Enjoy! :)

    NOTE: Downloads have switched to being hosted on the XDA DevDB Project Downloads page since AIK-mobile now exceeds the 20mb zip attachment size limit.

    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!


    Android Image Kitchen v2.8:
    - general cleanup using if/else and absolute paths wherever possible and removing hidden hideErrors option for simplicity since it's no longer needed
    - add detection if running directly from a command prompt and do not pause if so
    - add error catching for unsupported/unrecognized formats on repack, and compression formats on unpack
    - update unpackbootimg and unpackelf binaries from my repos
