iPhone 4 iOS4.2.1 Stuck in recovery mode

**llinxx** · 02-03-2011, 05:52 PM

So my iPhone was working fine and I decided to change the font using Bytafont. The phone crashed and wouldn't re start so I turned it off and went to boot tethered from my PC.
However, the phone got stuck with the pineapple on the screen and wouldn't boot no matter what I tried.
So I put it into pwned DFU mode and tried to restore it using iTunes, but I keep getting error codes! I have no clue what to do.
Now when I try to boot from tethered the pineapple appears, then the apple logo appears, then I get the USB/iTunes screen.
Any help would be greatly appreciated!

Once dfu is done, run itunes : shift + restore to cfw of 4.2.1
Run redsn0w again , choose install Cydia and tether boot after restoring to cfw of 4.2.1 ( in your PM box )
