Hey everyone. I'm having major problems here. I've tried nearly everything but no luck. I started out with an iPhone Jailbroken with the Pwnage Tool for 3.1.2. I then created a custom firmware for iOS4 and when i put it in DFU mode and restored it it appeared to be fine but it hangs near the 98% both on my mac and on the progress bar on the iPhone. I left it for an hour or so and no luck. I removed the iPhone and put it in DFU mode again and tried several times and no luck then i gave up on the jailbroken firmware and tried to install just the normal iOS4 and now that won't even install it always hangs. I tried installing on my Mac and a two PCs and no luck. I was able to go back to 3.1.2 once, but only after several tries. I really want to go to iOS4 because of all the new functionalities. If I go back to 3.1.2 it will have been a waste of 8 hours of my life trying to upgrade. Anyone have any suggestions?
