I DO NOT have a computer.
I noticed while in recovery mode an option to update via sd card.. I want to update my phone to Android 10 is that possible to do via sd card and no pc?
Also is it possible to flash stock firmware with no pc and no root? How? Not and never been rooted. (dont know how to)
I want my phone back to complete stock whether on Android 9 or 10, all data is backed up already.
If not possible can I root without a pc?
