AC Question
I had to root my brand new Galaxy J7 (SM-J710FN) to restore my previous data backed up with Titanium backup. I have my data back so i decided to do a nandroid backup as well with TWRP. However, the backup always failed stating this error "E: Failed to mount /data". I am not well versed with android and its commands and whatever little I know is only because of my consistent internet searches.
I decided to give up so I unrooted the phone and flashed the stock firmware. Now I want to check if the boot loader is locked. I am listing whatever problems I am facing right now.
1. Whenever I boot into recovery I always get “installing system updates” message and then I get to the recovery mode.
2. After selecting the option “Reboot to bootloader”. The phone gives an” E: Failed to mount /data (Invalid Argument)” error and restarts normally.
3. I have adb and fastboot installed on my pc. ADB works fine but fastboot commands draw a blank.
As of now I do not have any problems with the phone since its working as it should. Can some please explain the errors that I am getting in my phone?
Thank you!
