A simple build guide for AOSP-based ROM on cezanne is in Wiki now!

A buildable device tree for the Redmi K30 Ultra (codenamed "cezanne") written by beginners, borrowing a lot from the RMX3031, chopin, atom and the original cezanne device tree. It may contains many non-standard commits, Just ignore these please :P

💖 Thanks a lot to

RMX3031: @ManshuTyagi ,
chopin: @Yuyuko ,
atom: @HuaLiMao-AQ , @Jale Shaw ,
cezanne: @Xayah , @nzlov , @ZhcnPanda , @Raspberry Kan
and others contributed to it.

Known issues

• Volume adjustment when taking a call
• Deep sleep (Only takes up half of the standby time) and no deep-sleep time when AOD is on
• SELinux: Permissive
• Maybe more...

NOTICE

Before starting the build, make sure you have commented out the third line in device/custom/sepolicy/common/private/property_context
