iPhone 4 V.4.3.3 - Black Screen
My iPhone 4 used to be 4.1 BB 02.10.04, and I wanted to upgrade to 4.3.3 so I installed the sn0wbreeze v.2.7 and I built the custom IPSW and I restore it on iTunes with TU and iReb help and finally I got the file restored then I opened the redsn0w_win_0.9.6rc15 and I picked up the offical apple custom firmware (iPhone3,1_4.3.3_8J2_Restore) then I choose "Install Cydia" and "Allow Boot animation" then I did the same steps but finally I picked up "Just boot tethered right now" then I opened the iTunes and I found my iPhone was restored and detected with the new 4.3.3 version as you see in the picture attached, which shows that everything looks normal but the weird thing that my screen is deadly black and I can't figure out what's the problem although everything on iTunes is normal; I can add apps, pics, sync contacts but finally the screen still black.
to summarize, everything is normal on iTunes only but on the iPhone its completely dead giving a black screen. PLEASE HELP!!!!!ImageShack® - Online Photo and Video Hosting
