I am trying now since 5 over 5 hours to get stock OS for my 7T (hotdogb) with LOS 20 back to stock OS cause of safety net not working as well as some other stuff which i want to reset… But i am unable to install neither TWRP nor default stock OS. I am stuck with LOS recovery and cant install stock OS cause LOS is newer, and it would be a downgrade, letting it fail the upgrade via ADB. I tried with payload dumper and there the partitions are locked even tho oem is unlocked. I ran out of ideas, anything I can try?
Regarding TWRP: i tried both stock and other rom version, it did not work.
