I get an error: no successful firmware download after 60000ms!! Giving up. Do I need to download something that I didn't?

Are you absolutely sure you're running iOS 4.2.1 and you didn't update to 4.3?

I had that error, first time round on an iphone4,just hard reseted to get back to springboard, on second attempt it happened again, I left it connected as I was gonna go googling, but suddenly it just restarted and completed the process.

Make sure you have a good, non-proxied internet connection on the computer you're running GP on.

Make sure you have the latest iTunes installed.

Delete the 2 payload files from the previous GP attempt. They'll be in the folder GP is in, named iBSS.nXXap & kernelcache.release.nXX.

On a Mac they will be in

Run GP again.
