4G will not restore

[tankcr]

Hey all, I have been trying for 2 days now to get this thing restored. I plugged it into my car deck and it immediately rebooted to the apple symbol and stuck there. Using every tool I can think of I have been able to get it into restore mode DFU mode and pwned DFU mode, but no matter what during a restore out of iTunes it gets to loading the OS and the progress bar stops at 0% Itunes says waiting for device, after a couple minutes the screen flashes white and it goes into the restore mode with the little Itunes symbol and the plug in symbol. I am stuck, and frustrated any help would be hugely appreciated.
