Hello. Recently I bricked my phone to point that it only show a black screen, and the notification light when connected to a power source; I got there by flashing a ROM that was intended for another regional model of the phone (I didn't know at the time).
Now, I know that this questions are morally wrong, but I want to know the answer prior to hand the phone to the technical service provided by the warranty:
Can they know that I flashed a different ROM even if the phone is in a "hard-bricked" state? This is important to me because the warranty covers the fix if they can´t prove that it was an user fault.
The other questions is, are there any non-user faults that could get a phone bricked, similar to a bad flash?
