[tj_ben]

Hi, Im new here and new to the world of Android Hboots and stuff.
Well I have this problem, I just bought in a pawn shop a used HTC Desire 510 (Virgin Mobile) with no battery, when I purchase the battery and turn it on, I notice that has a locked patern screen, I already tried to do a factory reset but it does not let me.
Here is what I am dealing with.
