This error message occurs when you downgrade or upgrade to a different baseband than the firmware your restoring to has. This message does NOT mean the restore failed – it simply means the phone firmware does not match the baseband. Put your phone in recovery mode and then kick the phone into normal mode and out of recovery mode and it will work.
Error 6 and 10
This error message is because of a problem with your firmware – this message will occur most often because of using unsuitable boot/recovery images. Make a new custom firmware to fix this and use suitable boot images or use the standard images that came with the pwnage software.
Error 1603/1604 – 160? something
IF YOU ARE RESTORING TO A STANDARD APPLE FIRMWARE *NOT CUSTOM FIRMWARE”
This error is down to itunes not liking your USB ports on your computer. Use a different USB slot or a different computer if possible. That is the easiest fix!
IF YOU ARE RESTORING TO A CUSTOM FIRMWARE AFTER RESTORING FROM STANDARD APPLE FIRMWARE
IF you have pwned your phone once and then restored back to apple original firmware successfully and THEN tried to restore custom firmware you WILL get an error in iTunes as the apple firmware “unpawned” your phone. You have to repwn it using iPwner and then you can restore using custom firmware.
IF YOU ARE RESTORING TO CUSTOM FIRMWARE AND YOUR PHONE IS STILL PWNED
See “if your restoring to apple firmware” above as it is the same issue.
