Thanks. Maybe you're right, but I don't think I'll rollback to those older versions. I use Migrate for backing up apps and it doesnt require custom recovery, so I'll live without TWRP... At least until I get bored with stock and go for crDroid againHi Lord Sithek
As i said before i think it is to do with compatability between the rom version, magisk version and twrp version. If you get lucky with all the versions working together then all works otherwise frustration.
My TWRP version was 3.4.0-2-gts4|wifi
BUILD NUMBER QP1A.19071.020.T720XXU1BTG3
this might be helpfull if you ever try again.
I have also got a twrp backup of a clean instal of android 10.
All the best ExTall
