Hi!

Updated to iphone 4.0.2 and yes, i failed, entered into DFU mode, trying to restore and it just doesn't work at all anymore..

just keep getting errors back.. says it's successfully installed onto the phone but when i plug it back in it says "itunes has detected iphone is in DFU"

Try on a different computer. Download the 4.0.2 file directly on that computer.

If you don't have a different computer download the file again on the current computer. Maybe the file is corrupted.
