Ok, working on an iPhone 5c for my cousin. He said before he gave it to me that the battery went dead and would not take a charge. So, i have another iphone that i put his battery in, charged it up, and moved it back into his phone. It still is not responding. Ive tried hooking to itunes. Nothing. Tried holding home and power button. Nothing. Changed out the charging port. Nothing. Im guessing it has to be hardware related. Does not seem to have any water damage. What else can i try?
