Ok, I had 2.1 going but it was messing up and slow so I wanted to redo it. I restored to 2.1 with itunes that worked fine. Got to the start up screen for emerg. calls. Had IMEI, etc. Then I created the custom file with the ownage tool. Went to DFU and restore and I get error 21 consistantly with all different usb ports. If its not error 21, its error 1600 in restore mode.
What do I do now?
