I need some assistance, fellow /e/OS enthusiasts. I need a software/technique to fully back up the phone OS, before installing /e/OS, in case I need to revert to the original firmware/OS. (not just the apps, contacts and settings, but the whole firmware)
My first phone was upgraded to /e/OS without such a backup and now I cannot revert it back to its original Android flavour.
I’m sure this topic must have been extensively covered somewhere in this forum, but for the life of me, I just can’t find the right thread or the right doco.
Can somebody point me in the right direction, please?
