I regurlary took nandroid backups on my pc with TWRP (adb backup --twrp) of my phone, one day i needed to restore one and i found out i wasn’t able to, the restore would stop midway and i needed to completely reset my phone…
Probably the corruption could have happened because i originally took the backups on a PC with a Ryzen processor, that’s what i managed to figure out.
Anyway now i wanna make sure to have safe and healthy nandroid backup, is there a way to check this without having to try to restore on an emulator every time?
If you search it online you can find that people have some issues with computer running amd ryzen processor and the adb and fastboot commands, i don’t know if it’s the case, but i couldn’t find any other reasons on why a TWRP nandroid backup that was completely fine when i took it and didn’t prompt any error couldn’t be restored.
It’s not a disk image, it is a particular type of compression that packs up different parts of the system (system, data, vendor etc…).
I also tried to enter the backup by using a tool that converts .ab backup in .tar, but i didn’t manage to do it.
Anyway i don’t really care if i lost that particular backup, i just want to avoid it to happen again
