Chosen Solution
Hello All, So I replaced the screen to an AT&T iPhone 4 and the phone will only go as far as booting up to the Apple Logo and does not do anything else… The Apple logo stays on for about 30 seconds, the screen goes black and then the Apple logo comes back on for about another 30 seconds and continues this process….
I think you have damaged the battery during the install. Try another battery and see if that sorts it
discconect your phone from the computer, wait for it to power off again, then hold the home button down and plug it in, hold the home button until itunes asks for a restore, then let me know how it goes, I have this problem with a 4, might be the battery or a loose connection are my suspects so far, Keep on rocking in the free world.
