This Samsung phone was given to me. I had no clue about the frp when I reset it. I wondered the easiest way to get past it because I'm like two days into starting to learn this stuff and I'd like my phone back. There are two messages on the recovery screen I don't understand. The first is:
E:ensure_path_unmounted failed to unmount /efs (device or resource busy)
I would also like to add that I did factory reset it once without the sim card in it I'm not sure if that affects anything.
The second message this one is at the bottom (the other is at the top under the menu says):
E:failed to open /dev/block/bootdevice/by-name/misc: No such file or directory
Actually reading through it there are two more similar to these two.
