So I have an iPod Touch 2G with 8 GB. I had jailbroken the 4.0 GM with redsn0w 0.9.5b5-1 earlier. I have Windows 7, so I had kept getting a black screen on my iPod once the jailbreak was done and so it never finished. So I had redsn0w run under compatibility mode with Windows XP and it worked. Fast forward to yesterday when the new redsn0w was released and I wanted to update so I could use iBooks. Problem is... the black screen returned. - Tried restoring to GM... didn't work - Tried restoring to official 4.0... didn't work - Tried running under XP compability mode... didn't work - Tried running as administrator... didn't work - Tried running my computer under safe mode with networking... didn't work - Tried doing a completely fresh restore... didn't work - Tried using the earlier beta to point to the GM while I was on the final 4.0 firmware... didn't work I tried every solution I could find via Google, YouTube, and this forum. The worst part is... now I can't jailbreak it at all. I can't jailbreak my 4.0 GM with the earlier redsn0w beta anymore either. So as of now I'm stuck with the official public 4.0 release, and I can't jailbreak it for some reason cause I can't get past the black screen to finish the jailbreak. Anyone know what I can do? I would GREATLY appreciate it! I just want 4.0 jailbroken with multitasking and homescreen pictures, and iBooks working.
