Hi all, A root newbie here. I'm rooted with twrp recovery. I have it read only mood I think. I made a nandroid with efs. Now I have the phone set up the way I want with couple of changes in build.prop etc. Now I want to back up an image in a way that down the road after flashing a different factory image or something like that, I can just restore this backup to have the phone the way I like. I hope I explained it OK. Please advise and thanks.
