I replaced my IPhone's LCD screen. When I put it back together I got the black screen with the apple logo. I waited for it to boot but eventually it would display a clocking circle on the apple. After a while it would turn off then on and do the same thing again. I turned it off by holding down the two buttons. Then restarted it and I got the same thing. So I tried doing a restore by holding down the circle button and connecting it to my compute with ITunes 9 to put it in recovery mode. The recovery completed and it told me to leave it connected to the computer and wait as it would shut down and restart the phone. The phone restarted, however it resumed with the same restart sequence as before with the apple logo and clocking. At this point I tried anyway to restore the my phones backup from Itunes 9 onto the phone. It didn't complete as the phone kept restarting and displayed a message saying there was an error. Then my computer froze so I restarted and tried again. To my surprise it started syncing the phone with all my programs and files. However the phone still will not boot up or go past the apple logo screen. Any ideas why this would happen or how to get it to boot?
