Is it okay. Ive always wondered if nv backup will be good and im guessing since im doing from recovery that would be good aswell. I have way too many files and I just want to wipe and format . So is it safe. Any downsides. ? Thanks
Wipe and Format would be like wiping and formatting an External SD Card. If you have any information on the internal that is needed make sure to back it up. You may need to setup the phone again like doing a factory reset.
