iPhone 4 - Error 9 during Restore

I have the same issue, had the latest install of iTunes, the phones is literally 2 days old.
Plugged it in to my MacPro for an update and getting the error.

Running a restore now, not really happy about this.
One more stupid issue like this and I'm grabbing an Android.

I Don't need the hassle.

I had this problem on 4.0.1 and 4.0.2 during the firmware upgrade process. Each time had a different error message, but my solution was similar in both cases.

I am behind a firewall, so to troubleshoot:

The first time I jumped onto a "guest" wireless network, and was able to complete the update right away.

The second time (error 9) I added exceptions to my (Astaro) firewall allowing the URLs provided in apples article TS1275.

Point being, if you can access a different network (maybe without a firewall), you might have the same luck I did.

The error 9 threw me off, and I was swapping USB cables, trying different PCs etc.

Good Luck

I had the same errors. I changed usb ports on the computer and it worked.

I got this going too. Failing in the same spot during "Restoring iPhone firmware" a few times now. I turned off the firewall, changed cables and changed USB ports and so far no luck. Error 9 and error 31something. Would be strange if it were my PC after a hard boot, port and cable change especially seeing as the firewall is off. But, thats about all thats left so I'm off to try another PC.

This is EXTREMELY frustrating. Same issues here.

Have tried with the computer the 16GB iPhone 4 is synced with, both USB ports, 4.0, 4.0.1, and 4.0.2. Error 9. Rebooted twice. Still nothing.

Ditto for my own Core i5 MBP, which I used earlier this evening to update my own 32GB iPhone 4. Reboots, different USB ports, iPhone on/off...error. Status bar underneath the Apple logo gets about 60% of the way there, then either Error 9 or no information at all.

So that's 2 Macs, 4 different USB ports, 2 different downloads of 4.0.2, and I have a brick stuck in recovery mode.

Of course AppleCare's closed. Guess I'll have to schedule a Genius appointment tomorrow. This *****. Why would the update work just fine with one iPhone 4 and not the other?

Well Applecare's open HERE (western Pacific). Our calls go thru to Singapore. Went thru first level tech, no go. Second level tech tried a few other things, but couldn't get the update to go thru. Asked for iTunes updater logs and System Profile to be emailed to them.

Clearly some issue related to the updater. Always a worry when Apple has to do anything quick.

Same problem here with a Mac. Since it is late in the day I've made a Genius Appt for tomorrow early afternoon. I've done all the troubleshooting tricks I can think of (complete R&R of iTunes, mobile support stuff, changed cables, changed ports, removed backups, etc.). It always gets to the same firmware update point and punts.

Seems I had to do one restore when going to iOS 4.01 .. so I'm now wondering if it's the phone hardware (since I've done a complete swap out of my MacBooks iTunes-related software.

But I'll keep trying: I really don't want it to be the phone, which is great in all visible and operational respects.

I know I won't be updating my wife's iPhone 4 until I get this resolved.

OK, finally worked, but to be honest i'm not sure what made the difference. Tried a different USB cable and port and rebooting my iMac etc. I thought i still got the error but then it took me to the "set-up as a new phone or from backup" screen in iTunes. Thank the gods!

Problem SOLVED...for me.

Went over to my 2nd choice when troubleshooting Mac/iPhone/iPod issues, MacRumors.com. In their forums, I found a link to a "RecBoot Exit Only" application bundle. I followed the instructions in the iPhone Forum section of the MacRumors.com 'site, and am good to go.

The 16GB even shows 4.0.2. Looks like 4.0.2 can't get out of Recovery mode or whatever it's in, but that app did the trick.

Tried the "RecBoot Exit Only", per your suggestion.

Didn't work.

Gosh, am sorry. Was really hoping it would do the trick for folks with issues.

Does anything work, ive been trying to "restore" my 1 day old iphone 4 for like 2 hours now, i keep getting error 9... has anybody had luck after receiving this **** error!! Man, apple is really dropping the ball here seriously!!

Hey there, just wanted to inform you that I had the same issue. Finally figured out with the help of customer service, the my Verizon Family Protection software had to be disabled. DISABLE ANY protection type software. Then re-enable when you are done.
Hope this helps!

That worked for me when this happened with the 4.0.1 update. I thought for sure they would fix this issue before the next update, but apparently they pushed 4.0.2 out the door a bit hastily. I'm about to try RecBoot again if this restore attempt doesn't work.

Let us know what worked for you. Disable all protection for the time being... Do some reboot, change sync cable and usb ports...
