I have a customer’s phone and the device keeps flashing the apple logo. I’ve tried to enter recovery mode but its unresponsive. I’ve tried replacing the battery but either the phone wont turn on or the problem continues. To be clear, the apple logo shows up for 3 to 5 seconds then will turn off for another 3 to 5 seconds then repeats. When i connect the phone to the computer it isnt recognized. Anyone have any leads?
Sounds like a battery issue to me. The logic board is fine, but newer iPhones won’t boot, if there’s no battery power connected, even when the Lightning dock is. Watch out, keep playing that way, and you’ll fry the u2ic iPhone 5c Battery Replacement iPhone 5c Battery
