As you can tell, I've been banging away at this for a little while. It's not working. When the shift+restores fail to update, I get white screened on my iPhone 3GS. I can't bring my phone back to the original settings, I can't update it.
I've restarted my computer in here a few times, switched USBs etc. Any advice as to what I'm doing wrong?
*EDIT*
Note, most of these errors occur on verify with Apple, the shift+restore to 4.2.1 fails while preparing.
