Yes PE have a maintainer for Mi 10T/Pro and last build Is A11, update for A12 I don't know when come out from official maintainer, I ask PE devs for get my work as official and if I can maintain the device, but Say that the maintainer Is present... So I build my-self the rom, and post here, at least I don't use the original kernel and device tree from official PE A11... And today I finally fixed the selinux that now Is in enforcing, and the rom Is build with all Major requirement from PE source... So the unofficial string, Is only a string, from my side. Works all in rom, also GPay... I Mark It as stable.
Everything works fine but when I reboot to twrp it doesn't mount data its shows sdcard storage as 0 mb how to fix this and wanna let u know that this only happens in this rom for me i have twrp 3.6 v1 that supports a12 roms
you can install this rom like other custom rom, wipe all and then flash the zip,
yes you can install which version you will, but I raccomanded the V2 that is with selinux in enforcing,
and is the pixel experience, like an official, with all pixel goodies.
