I posted this on other forums, but please answer here too.

I have been having some troubles with my iPhone lately, so I decided to restore. When the custom firmware that I usually restore with didn't work, I restored to the default and wanted to jailbreak it with iLiberty+ for Mac. After it said "Preparing for jailbreak" for over 30 minutes, and with my iPhone still being in restore mode I decided to quit the application. Bad idea.

When I turned the iPhone on again, I saw the scrolling white text on the black screen that you usually see when jailbreaking your phone, but my iPhone wasn't even plugged in anymore. Now when I try to restore my phone, I get error 2001. I'm out of ideas, what do I do? Thanks.

pwned?

DFU mode, then restore.

That didn't work, but then I found a combination of things to do that would make my phone work. It works now. Thanks anyway.

Do you still have Dual-Booting iPhone?, maybe that's why DFU didn't work.
