I'm using ArrowOS 11 and want to upgrade to ArrowOS 12.1. What do I have to do? Is there a short instruction?

Thanks. Does it work with TWRP-3.5.2-sweet-Nebrassy.img? What did you wipe? Davlik, System and Cache? Do the apps, settings and magisk remain or are they deleted?
You need the newest 3.6.1 TWRP. Wipe Dalvik, Data, internal and system. After that ever Thing is deletet. I am Note Sure about magisk, but I Thing its also deleted.

Hey all :)

- How do I change refresh rate down to 60Hz?

It's very important to me to save battery life.
Plus the whole system is just snappier at 60Hz as well.

I'm sure many other people would be interested too.

Edit: Figured it out. Use SetEdit, and change peak and minimum refresh rate to 60.0, save. Done.

I'm still getting massive battery draining overnight (around 20-30% some days) on lastest ArrowOS 12 and Vantom Kernel. Anyone else facing this? Any fix?

Check any navigation apps etc running in background. I also installed Universal GMS Doze (Magisk module) and it seems helping. You can check: Settings → Information about phone → Running time (if Deep Sleep has some %). Before that my PixelOS was showing Deep Sleep 0%

    Just some information :

    Downloaded ArroOS12.1 Vanilla (RN10P Indian Version 64 MP)
    NiksGapps didn't work ( insufficient storage ) so I used Flame Gapps basic.
    Also TWRP 3.6.2 failed to format data but 3.5.2 worked perfectly.

    Fastboot flash recovery twrp.img
    Fastboot boot recovery

    Now in twrp flash ArrosOS zip
    Reboot to recovery
    Format Data
    Reboot to recovery again
    Flash FlameGapps
    Reboot System

    Edit : Fingerprint didn't work whatever I try, Going to try PixelOS

    It's not polite to demand features in something that is being given away for free.
    OSS or MIUI vendor? People on RN 10 pro using different vendor so it would be helpfull if vendor mention.
    OSS, as all my builds.
