After I gain root and flash kernel via fkm it bootloops... Then I have to manually flash the full Ota and re-root... Using magisk 24.307 and may update. Am I doing something wrong last update April worked without a issue
I can tell you there were no issues using FKM to install kernel. I'm updated to May factory image and using Magisk 24.3 stable.

Hi folks, here comes the monthly update, this month is a HUGE one since i decided to merge kernel common into Google's stable source.

Highlights on this release:
Built on top of Google's MAY 2022 12L source
merged linux stable kernel up to 5.10.101
merged android12-5.10 branch from https://android.googlesource.com/kernel/common
update to latest google clang 14.0.6 prebuilt version
added multi-gen LRU
source clean up (removed various drivers and superfluous commits)

Like always download link and detailed changelog in op.

Enjoy!!!!
So after updating to the May build and flashing 1.1.5 it bootlooped on me. I just re-flashed the May build that was patched with the latest Magisk build to get booted. Is Magisk 24312 not compatible?

Seems like there is a problem with using Magisk Canary with a non-stock kernel. Freak told me "Magisk changed the way verity is handled during the canaries and that's why things will change."

I was hoping that this Kernel might work with Magisk Canary, but that does not look to be the case.

Again, the problem has nothing to do with any of the kernels itself.

On pixel 6 devices flashing a custom kernel involves flashing 4 images to your device. boot.img, dtbo.img, vendor_boot.img and vendor_dlkm.img.

Simplified explanation:
Essentially with vbmeta flags for verity/verification enabled on your device, if you flash a source built boot.img, which contains an exact replica of the zImage from the "stock" boot.img the device will fail to boot due to verity not matching the original boot.img from the stock firmware.

Initially when the Pixel 6 just released, magisk did not have the "ability" to work around this check. So everyone that wanted to root their devices needed to disable this check (this is what disabling the vbmeta verity/verification flags does), as patching a boot.img with magisk alters the boot.img so it´s no longer a "stock" boot.img. Additionally with vbmeta flags disabled you´re able to flash other source compiled images to your phone, that are not stock which would trip the vbmeta check otherwise.

Then Magisk added the ability to disable that check by patching fstab. That enabled users to no longer having to disable the vbmeta flags when rooting their devices via a patched boot.img. As a side effect, this also enabled users to flash other non stock images to their devices without tripping the verity check if rooted with magisk. (this is the current state in magisk stable 24300)

Recently magisk was reworked and no longer patches fstab to work around verity. So while you´re still able to root pixel 6 devices without disabling verity flags by just modifiying the boot.img via those recent canaries(by magisk patching it), flashing a custom kernel will no longer work with vbmeta flags enabled while running canary, as it involves more partitions than just the boot.img. (this is the current state in magisk canary)


I´m not sure if Magisk considers this an "issue", as magisk in itself is not impacted in any way by this change.
It´s a very unfortunate change for anyone that wants to run a custom kernel and now kept vbmeta flags enabled over the last months. So essentially this might require falling back to the original method of keeping the vbmeta flags disabled each month if not other easy workaround this found.

    Latest June for Raven, Magisk 25

    No problems with latest 1.1.9!

    Will this run okay on Android 13 beta?...


    Well since no one wants to answer the question, I'm going to take that dive. I'll be right back ladies and gentlemen.

    Anyone tried it with Android 13 Beta?

    It's clearly stated at op and thread's tittle, no need to be answered by anyone, people just need to read a bit and NO it's not a good idea to flash it on A13.

    */





    hi XDA community, i'm here to share with you my little project, my primary goal is to provide a stable and fast kernel without compromising battery life plus some cool features that i find useful for the day to day usage.


    Current Features

    General List:

    Compiled using Google's environment for GKI kernel build for maximum stability but using latest google prebuilt clang 14.0.7 and fixed all code errors caught by the compiler

    Packed with Anykernel3 with ability to preserve magisk root, thanks to eng.stk and osmosis for bringing this to Pixel6 series

    Works on both devices (Pixel6 and Pixel6PRO)

    Merged linux stable kernel up to 5.10.110

    Merged android12-5.10 branch from https://android.googlesource.com/kernel/common

    Franco Kernel Manager update system support ( Copy/paste link for auto updates )

    Boeffla's wakelock blocker

    BBR TCP set default and a lot more others to choose

    Enabled power efficient workingqueues on various drivers

    Fsync on/off support

    TTL spoofing support enabled

    Usb fast charge option

    CleanSlate Features from @tbalden, all credits for the features to him (s2s, notification booster, battery saver, flashlight notifications. Note that rootless features like kadaway are not implemented here because we need root for other features to work properly with my tree)

    Dirty pipe exploit fixed

    Tie mechanism to prevent frequency spikes caused by small tasks into powerhal from kirisakura kernel

    Added Multi-gen LRU driver

    Added DAMON driver but disabled by default

    Source clean up (removed various drivers and superfluous commits)

    Other stuff that is boring to write, take a look at my github for detailed information



    NOTE: I'm shipping now the full gki kernel which means that no matter what kernel you were previously everything will get overwritten by flashing this via autoflash apps

    ONLY COMPATIBLE WITH APRIL AND MAY and JUNE SECURITY PATCH ROMS A12L

    [ RADIOACTIVE KERNEL INSTALL ]

    DOWNLOADS HERE


    First of all download the kernel zip of your choice, there's a flashable zip that can be flashed with your preferred kernel tweaker app and a FASTBOOT labeled zip with the necessary images to flash in fastboot if you want


    Radioactive Kernel fastboot images flashing instructions:

    NOTE: If you want to stay rooted patch the provided boot.img in magisk manager prior to flashing it via fastboot.
    You need to adjust your command to flash like you did when rooting the device.

    Flashing manually:

    vendor_dlkm.img need to be flashed in fastbootd, while the other images need to be flashed via fastboot/bootloader.

    How to boot to fastbootd?
    From running phone:
    adb reboot fastboot

    From fastboot/bootloader:
    fastboot reboot fastboot

    Once in fastbootd:
    fastboot flash vendor_dlkm vendor_dlkm.img

    Boot from fastbootd to fastboot/bootloader to flash dtbo.img and boot.img:
    Either select Reboot to bootloader option via buttons
    or type:
    fastboot reboot bootloader

    Now in fastboot flash boot.img and dtbo.img
    fastboot flash dtbo dtbo.img
    fastboot flash boot boot.img
    fastboot flash vendor_boot vendor_boot.img

    Reboot either via buttons
    or by typing
    fastboot reboot


    Flashing using authomated flash script:

    Run flash-RadioactiveKernel.sh in linux
    or
    Run flash-RadioactiveKernel.bat in windows

    NOTE: If you want to stay rooted if you gonna flash the fastboot images you MUST patch the provided boot.img in magisk manager then rename the magisk patched file to boot.img or modify the script with the correct boot.img name

    Enjoy!!!!



    Instructions using Ex kernel manager or any other app with autoflash support:

    * Flash Kernel Zip

    * Reboot

    * Enjoy!!!

    I'm also providing a similar magisk module like kirisakura kernel does but it's slighty modified and adapted for my tree all credits to Freak07 for the original idea, it's bundled into kernel zip, AK3 Helper Module , i higly advice to not remove it for better experience with the kernel

    AK3 Helper Module:
    Set ro.debuggable to 0 to avoid dev options fc
    Restrict maximum CPU-Freqs during screen off/ idle to 1.1GHZ for all clusters to save power thx to Freak07
    Tie mechanism to prevent frequency spikes caused by small tasks into powerhal


    Thanks and Credits to developers:

    Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:


    * SultanXda

    * Ordenkrieger

    * LordBoeffla

    * zx2c4

    * Freak07

    * osmosis

    * kristofpetho

    * tbalden

    * Chainfire

    * BitOBSessiOn

    * nathanchance

    * Yaroslav Furman

    * eng.stk

    * Flar2

    * joshuous

    * dabug123

    * franciscofranco

    * RenderBroken

    * moludo

    * Lozo2010

    ... I just hope I did not forget someone. If so, please let me know and I will add you of course.

    Thanks to all of you for your great work

    I also want to say thank you to my friends and testers and to those who donated me a beer or two;)

    Hi folks, here's the January update, a bit late lol but i wanted to make sure that everything is adecuate for my quality standards, i don't like to push half backed stuff nor untested software that can potentially be dangerous, so i made sure that everything is running flawesly before the release, hope the wait worth it.

    This build have the January source merged and tried to make the overall ux experience smoother also switched to clang14 because why not? Hope you'll enjoy it as much as me and my testers do.

    Like always download links and detailed changelog in op.
