Apple logo shows briefly, then disappears when connecting to power.
I replaced the screen and case of my iphone 5s, and now it won't boot anymore!
When I connect my phone to the power, it turns on, shows the apple logo for a brief moment, and then turns black until I disconnect and reconnect the power again.
When I connect it to the PC, iTunes detects the phone, and wants to to a recovery, but fails when trying to reset it to factory settings, or load a backup.
What defect can cause such a reaction?
I read that it can be caused by a faulty battery, so I replaced that as well, but it still wont boot.
I hope it is not a faulty U2 IC, because I don't have the skill and equipment for micro soldering.
Another info: My Home button is broken, so I cannot perform any operations that require that button :(
I thank everyone already for their help!
Edit: I just saw that it actually restarts, after some time, and displays the logo for not even half a second again.
Is this a good question?
