Custom Restore Problem iPod Touch 4G won't boot up

[lmvienna]

I used a method to downgrade without SHSH blobs and the guy on the video says to use redsn0w to boot tethred after the custom restore but the iPod gets stuck in a white screen while RedSn0w gives an "Unexpected error" after the reboot part. I tried everything: reboot my mac mini, hard reset the ipod, windows, everything! What can i do?

HELP PLZ!!!!!

Put your ipod into recovery mode then restore using itunes.

Which software are you trying to downgrade too? Also, if you want to downgrade, open iTunes, and hold shift hit restore, browse for your firmware, and restore. When you get the error, download a program called iReb, and hit exit recovery mode. Then your device will boot up like normal, and you will be able to sync it with iTunes. However, you will not be able to restore to your latest back up, because your firmware that you have downgraded to will be too old.

If you cannot find your firmware go here
For the iReb download go here
Good Luck!
