When everything will be ready.
Let's switch directly to February one.
Reflash clean one.
I have to check about Security patch, i've heard (don't know yet if its true) PE team dropped support for A11, so probably December its the lastest security patch (have to check).
Error 1 of twrp tipically its (if i remember correctly) related to wrong device recognition. Clean flash or change recovery and retry (try with pre-latest twrp release)
I can’t wait for android 12 after the screen, that you send on telegram. Do you have a release date?
