1 iPhone not powering up non responsive
iPhone 4s A1387 will not power up after being dropped. Not externally damaged on the screen. I have removed and inspected the internals. Battery connection good, no water damage, doubled checked all connections are seated, plug into wall charger and nothing happens, Charge port is clean and clear, all buttons function.
Have you tried DFU mode?
What happens when it is charged for 3 hours and then plugged into a computer?
