Restored my iPhone 4 from iOS 4.1 and now it's stuck in a reboot loop. If I put it into DFU mode with iTunes and click on restore, it never actually gives iTunes the chance to restore my phone. It is constantly rebooting itself. Please help anyone.

Followed the download link you provided, downloading the firmware (4.2.1 GoldMaster, right?) now. Hope this works!

Still didn't work for me, like I said before, the phone kept rebooting itself once the recovery process started.

you phone should be in warranty, visit near apple store.

Even when the device is put into DFU mode, it allows me to click on restore, but once iTunes starts to restore, it goes back to the reboot loop again.

Interesting

The same thing happened to me, I solved it by restoring it by using another computer, try it to see if it works for you too.
