-IF it can be unbricked/fixed, I don't care if it's difficult but I need to know if it's possible first.
-if the above is possible then what procedures should I follow
I'm probably asking for too much, sorry, but from what I tried to investigate it looks like it has more than one single problem so im not sure if all of them have a solution.
What the seller said:
The old owner sold it with the bootloader unlocked, I didn't knew that, so I updated via OTA (in the phone) and ended like that.
Looks like it can't have an unlocked bootloader if OTA updating, I don't even know please help me.
*since I still don't own the phone I can't test anything, I just need to know if those errors shown above have a solution, or at least are not a death declaration so I can still try something if I buy it.
Sorry for the bad quality of the images but that's what the guy selling it uploaded.
