This is a continuation of this question, but here are the facts: I have a rooted Samsung Galaxy J1 Ace SM-J111F running the stock ROM in Android 5.1.1. I used this XDA-Developers guide to root it. It suddenly got bricked via FRP lock so I tried to unroot it using the stock boot binary.
Here is an Imgur album containing screenshots and images of the phone during the unrooting process.
Description of images:
- The phone is set on Download/Odin mode.
- Odin is ran as administrator and is loaded with
boot-stock.tarprovided by this XDA-Developers guide.
- The settings of Odin.
- This shows that the flash has failed.
- The custom binary is blocked by FRP and I have to restart the phone to flash again.
I tried downloading from www.samsung-firmware.com and www.sammobile.com but all downloads have failed. It stops midway and asks for a HTTPS certificate and the archive becomes corrupted between 20 to 70 percent.
I therefore decided to wipe the data using the stock Android system recovery. However, after rebooting it, the binary is still blocked via FRP lock. I've wiped the cache as well.
What caused this issue and how do I solve this?
