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
AOSP R version will work on MIUI R but not all wil work like led

It does not seem to be working on xiaomi.eu miui 12.5 ROM port for Redmi Note 9S. It remains stuck on the Redmi logo but does not go into a bootloop. I'm on build 21.6.2 of the ROM. Any help would be appreciated.

It's ok, I've installed Havoc OS 4.6 on the phone. I have a question though: Would you recommend the kernel for better battery life? Performance is good on Havoc but the battery life is quite average.
I'm sorry but normally I am not interested in having a thousand hours of battery life.
And maintaining good performance without hurting the battery is not so easy or causes abnormal operation or lags.

I see. I guess long battery life is kind of redundant now with fast charging and all that. Anyways, I flashed your kernel on Havoc and it's working great. The idle drain at least seems to have improved a lot. So, thanks for your work I guess xD

    @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:

    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.
