"Unknown Error"

**blackmyke20** · 07-13-2008, 08:17 PM

Ok I just bought a unlocked iphone last night. Well not really thinking or knowing anything about them. I updated it and now its locked. I finally find out everything I have to do and look at all the youtube videos. I get to the part where I hold the shift button and press restore. I select "iPhone1,1_1.1.4_4A102_Restore" and press open. It then loads up and says "The iphone "iphone" could not be restored. An unknown error occurred (20)"

Anyone can help?

Thanks

I have the exact same problem, so frustrating! Tried all the walkthroughs but after accidentally bumping my iphone to 2.0 at 4am I have been able to get it going for a bit but it wouldn't unlock my sim, so I went back to 2.0 and now can't get it to downgrade. Keeps bounce my error 20, can anyone help?

Should I have a specific version of itunes? Anything lower then 7.7 doesn't recognize the iphone but 7.7 errors on me everytime
