iPhone 3G 2.2 --> 2.2.1 problem

[d4rklamp]

Hi, I'm having difficulties upgrading my jailbroken iPhone 3G 2.2 to 2.2.1... I have a custom firmware 2.2.1 which preserved the baseband, I've put it on DFU mode and when I try to upgrade, I'm getting the following message... Please help...

Try to enter DFU mode again, reboot your computer, and try a different USB port. With that error it just takes a lot of trial and error until it works.

Ok, it worked... The problem was DFU mode... should let the iPhone 3G connect normally then restore.... Thanks anyway
