    you can restore to 3.1.3 again but if you relied on an unlock you are probably out of luck unless you have one of the really old 3g's with the 5.8 bootloader since the baseband doesn't get downgraded with the restore, you can use forecast from ih8sn0w to determine the bootloader, if you have 5.8 you can use fuzzyband to downgrade the baseband as well

    Use iReb to dismiss the error.

    1015 use Recboot to kick phone out if recovery. That's just an error for a baseband downgrade failure, no worries tho, your phone has successfully been restored.

    ^Unfortunately, no unlock for 5.14.x ... for now.

    Keep an open eye for a new ultrasn0w. Rumors are it may come after 4.2 is released.

    Where can I find Recboot?

    TinyUmbrella and iReb both kick the phone out of recovery mode.
