Hi, I am currently using regular LOS (no microG) and I’ve started to think about moving back to /e/. My question is regarding OS reinstallation. Should I firstly use TWRP to clean up the phone’s disk fully, or it would be enough to
go to LOS recovery
delete all data
restart the phone to recovery
install /e/ os zip file
just use /e/ (+ plus I am not sure if in this way I would have /e/ recovery mode on the phone.
On most devices, you can’t install /e/OS over a too much recent LOS because the related security patch date (2023.01.05 for e-1.8) have to be newer than the already installed one.
Then I think you will need to format data partition (not just wipe) and wipe system. All your user-installed apps and data will be gone unless you are able to create ar restorable external backup
