This 3GS was run over by a trailer and I disassembled to try and repair but the first thing I noticed was the logic board is warped! I put a working display on it to test it because the digitizer and LCD were crushed and it’s not doing anything. Is there anyway to fix a bent board also is this what is causing it not to work?
I think you can be sure that if the logic board is bent it is not possible to fix it.
