Logic board works in antoher Ipone 4
I have an Iphone 4 that was, what i thought, completly dead. The cause was probably water damage. I tried everything to get i going but it seemed "fried". However I got an idea to try the logic board i another working Iphone 4 that i´ve got and to my surprice it seems to work fine. I then tried the functional Ipone´s logicboard in the busted chassi and it too didn´t work.
What could be the reason for this? Could it be some flex cabel that is busted or some grounding problems?
