I have a 3G 2.2.1 trying to unlock with PwnageTool in Expert mode, made the partition to 600mb and even tried 1GB...
I created iPhone1,1_2.1_5F136_Custom_Restore.ipsw and when it goes into DFU mode, iTunes opens and it gives me error "an unknown error occurred (2001)" and it thinks it's and iPod, so I take the iPhone off DFU by turning it on.
It shows up into iTunes, I use the restore with the option key down, it extracts the image and right when it's about to restore with custom, I get an error message, "The iPhone "iPhone" could not be restored. An unknown error occurred (21).
At this point the only way to get the iPhone back to normal is by restoring it to the original Apple image.
Any help will be greatly appreciated, thank you in advanced.
