Restore Errors/10xx

Error 1002
Error when restoring.

Error 1004
This is caused by a failure to match the Baseband Nonce currently in memory to the nonce returned in the Baseband Firmware SHSH blob. This happens if you edited the hosts file (Saurik's Server) or you are using TinyUmbrella. Use TinyUmbrella and "Kick Device Out Of Recovery" to boot. 1

Error 1011
This is caused by recovery mode being in userland (1.1.1 firmware). The file iTunesMobileDevice.dll is damaged or updated.

Error 1013

 * iPhone 4
 * This means that the baseband did not get updated. Either remove the gs.apple.com entry from your hosts file and let the baseband upgrade or if you want to preserve the baseband just jailbreak at this point to boot it up.
 * Other Devices
 * Restart computer; change computer; reinstall system, if the device is always in restoring mode: XP users can jump from restoring mode with ibus; MAC users can use iNdependence. (usually on the iPhone 2G with 1.0.2 firmware downgraded from 1.1.1)

Error 1014
This occurs when you try to downgrade your device's baseband.

Error 1015
This error is common when downgrading iPhones and 3G-enabled iPads. The problem occurs when the device's baseband has a higher version number than the baseband in the firmware you restored to. Just set auto-boot true in iRecovery or use iREB/TinyUmbrella/RecBoot.1 In case this is not working use Pwnage Tool to create a custom firmware WITHOUT the iPad baseband, put your device in pwned DFU mode and restore via iTunes.
