IPhone :: 2G Gives Error (23) With Recovery And Error (1600) With DFU

I have a friend's iPhone after he seemingly bricked it by using blackra1n and then wanting to unlock it so he used blacksno and then he said he got something called buetbunueter and he thinks he hit a wrong button and screwed it all up.

I started off by trying a simple restore of the iPhone as that is basically the only thing that will come up consistently. Unfortunately I get error 23 and the phone cannot be restored. I've tried 1.1.2, 3.1.2, and a custom 3.1.2 from Pwnage.

I then went into DFU mode and tried all 3 firmwares again, but this time I got error 1600. So, yet another failure.

I've tried iRecovery and that doesn't seem to help and I've tried using blackra1n again but it just seems to hang on the logo when it is supposed to be rebooting.

Anyone have any ideas or tips, I've been googling for about 2 hours and have seem way too many blogs.
