4.0.1 Errors! Post here!

No errors. No problems. iPhone 3G. Update from 4.0 to 4.0.1 went smoothly start to finish. Took a while to download, but it worked fine.

Y'all might restore to default (after backing up, of course) and then reinstall the new update. Let it run its course.

It appears that my phone has successfully restored. I did NOTHING differently than before, but simply tried again.

I wish you all the best of luck.

Is it likely to be server issues then?

It does appear to be server issues

Were you experiencing error code 9?

I'm having the same problem everyone else is reporting with the upgrade timing out 2/3 of the way through. I've tried all the things recommended on the Apple site, from deleting software, trying another computer, etc. This is very frustrating and yet another black eye for Apple.

I'm using my Macbook and Mac Mini to try and upgrade.

I'd recommend people hold off on upgrading to 4.1.

Anyone had any luck at an Apple store?

Error 9: This error occurs when the device unexpectedly drops off of the USB bus and communication stops. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB isolation troubleshooting, using a different USB dock connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

I've been trying for ages. But this last try has worked. Have done nothing different. I'm sure it's a server issue.

Hope everyone gets theirs sorted soon.

No errors here. It took an hour to download the update, then everything was fine. Exactly what is the update supposed to do, though? If it fixes the bars, then I'm out of luck; I have no bars on 3G,showing just dots.

I'm back from the store.

"Ed" diagnosed the Error Code 9 issue as "Stuck in Endless Restore Loop."

New iPhone 4 in my hands. (and yes, the front is a lighter shade of black... very noticeable.)

I don't think the issue has anything to do with USB, regardless of the code it threw. If you read the log, you see it hangs on contacting Apple servers... so I agree, it may just be a server issue.... but I was not taking any chances. Too much stuff going on right now to not have a phone for a day.

Thank you to Ed at the Maine Mall store.

Connect the phone to a USB port on the computer (preferably in the back), not an external hub or keyboard port. Disable all firewall and antivirus/spyware apps.

If the phone has ever been jailbroken or hacked to unlock, all bets are off. Say hello to your new paperweight.
