How to return to former kernel, if I don't like yuki kernel?
If you want to return to kernel built in rom, the easiest way is to dirty flash the rom, will overwrite the kernel too.
Other possibility is to extract from rom zip the boot.img and dtbo.img, then flash in recovery (never tried...).
Making backup before try any of this, is a smart idea...

(Joyeuse or curtana) if u have Joyeuse go HERE Xiaomi eu page scroll down when u see date: Edit October 23, 2020: LR.TWRP 3.4.1B 0530 read this instruction and get this Twrp and install or if u have working good TWRP unroot ur device and Root with magisk . stock miui roms dont like normal super su root. and maybe this is problem why LMK killing ur apps

Hey, That is last update for Miui Rom i think 2020-11-29...
there will be some update for miui or only just for a nasty AOSP.​

The miui kernel will be updated until xiaomi releases Miui R for all devices.
I have no plans to install MIUI soon and if I do it would be to install the version of miui R for the firmware.

Hello guys, I want to flash yuki kernel while I have another kernel in place... So how should I flash yuki kernel? Should I dirty flash it or should I start from scratch?
remove any magisk module installed by your old kernel or ypu will have problems with yuki kernel
after installing make wipe cache

Hi, just a question. I'm running latest version on fluidos, is it normal that selinux changed to permissive after flashing the kernel? Everything running great though! Thanks!

Thanks

(?) the double tap to wake is handled by the power hal if it is propper configured it works
also 3finger screenshot is handled by the system so it should work too

All of them works on xperience rom.

I just flashed yuki on Curtana (RN9P - India). I have a couple of questions if anyone can answer it would be a great help. I am using FKM since I purchased it some time back. Please note that FKM does recognize Yuki Kernel is installed.

1. Manthilla governer is not shown in FKM, has anyone experienced this before? If so, have you found any workaround / fix?

2. The automatic update JSON is not working in FKM for me, it returns an error code " The JSON url seems unreachable with error code-1" Any suggestions on this?

Note: My ROM - Pixel Experience (Android-R) by XRPDigital and blackman01 for Curtana. Yuki Kernel file flashed - 4.14.231-Yuki-Kernel-Redmi-Note-9s-Pro-AOSP-R-2021-04-23.zip (23-04-2021 build from Miatoll folder)

Thanks in advance.

Q version for Android 10
R version for Android 11

MIUI version should be Android 10
android 11 has been released for joyeuse officially about a month ago, new version of miui is 12.0.1.0.RJZMIXM, previous version was 12.0.3.0.QJZMIXM which was on android 10. that's why i'm asking since it was developed when android 10 was the latest on joyeuse at least, and it hasn't been updated since

    @TeamMex This is a very fine kernel. I am currently working with using it (compiled with clang-11.0.4) as the kernel for OrangeFox Recovery, and it is looking very promising. :highfive:

    • Xiaomi (MiCode) for kernel sources
    • Code Aurora Forum for kernel changes
    • Google for easy access to PSI Pidfd changes

    hey @TeamMex ! great to see you developing for our device. I remember your Xperience Rom was one of the first roms i flashed back in the day on the original moto G lol. looking forward to trying this kernel :)
    Nice :D

    Yesterday, I installed yuki kernel on my joyeuse phone, it was really strong but after flashing I haven't been able to use my hhd hard drive
    My device didn't recognize that
    So I forced to flash stock boot

    fixed!

    It is possible to update
    new curtana branch?

    Because aosp has a newer branch

    Rebased over LA.UM.8.9.r1-10600-SM6xx.0 (AOSP variant only)
    Merge Tag 'LA.UM.8.1.r1-16200-sm8150.0'
    Wifi, LA.UM.8.9.r1-10600-SM6xx.0 audio tag applied

    I would like to check if galileo and dual gps work.

    Because cortana has this kernel there is no galileo and dual gps.

    I do not have a lag system
    check the miatoll core to see if it can detect galileo indual gps

    I am also joining the request

    Not needed to switch to new branch i merged it

    What about fix TTL feature?

    It should be working on the latest version.
    let me know if not.
