"Could Not Be Restored - Unknown Error Occurred (2001)"

I'm receiving a similar error. It seemed to brick my phone once but I was able to restore to 1.1.4. I tried the update again and now my phone won't even restore. At least the first time I was able to make emergency calls. Now nothing . . .

Yep, I have the exact same issue. Any help would be great-I can't even restart my phone...

The good news is the problem is not your phone or the software but Apple's Servers.I have your exact problem. The bad news is you won't be able to fix your situation until enough traffic is off of Apple's servers. Apple is not sure when these issues will be resolved. I actually got through to Apple tech support earlier today and was advised not to try to update my phone till Saturday or Sunday at the earliest. They were very, very apologetic but Apple took on to much by launching the new iPhone and 2.0 software update worldwide all on the same day.

I was speaking with tech support today. The servers are flooded with users upgrading itunes to 7.7 & iphone to 2.0 software. I was getting the error messages: could not be restored - unknown error occurred (9) and also (13). I tried once again and either I was just lucky and got thru to the server or my recovery path really worked.

Here's what I did: I was able to restore by turning off the iPhone by holding the "Sleep/Wake" button for about five seconds. If your iPhone is already off, there's no need to turn it on and then off again. Once it's turned off, press and hold the "Home" button and plug the iPhone into your Mac or PC. Keep holding the "Home" button and it will show a dock cable pointing to the iTunes icon. You can now release the button.

Open iTunes (if it's not already open) and you will be told that "iTunes has detected an iPhone in recovery mode". Click "OK" and you will be taken to the iPhone pane. Click restore and while restoring, do not touch any buttons until it's completed. Depending on the extent of your iPhone's ills, it may take some time to do a full restore. My iphone now works. I hope this helps.

I get the same message every time I try to restore either an unknown error occured 13 or 6. Maybe I just need to wait and try later

Got it to work after same problems in the end - unpug all your usb items, dont use the iPhone dock.

That didn't work for me; did it work for anyone else?

Thanks.

I kept getting error 13 or 6 when trying to restore but finally the sync and upgrade went through probably after maybe 30 tries over a period of 1 day

Just helped a friend with this exact issue. The key is make sure CLASSIC IS TURNED OFF. Just turn it off under system preferences (no need to restart) and run the iPhone update again.

THIS WORKED FOR ME!!!

I can't believe that I've gone without a phone all weekend when the solution turned-out to be so simple...THANK YOU!!!

I have the original iphone and after installing 2.0 software an error message came up -1426 unable to restore also a message stating that it could not be synced because the required file could not be found. I lost all my music playlists, my videos my iphone camera photos and my ring tones. Also I am not able to restore anything including playlists, photos videos and ringtones. Can anyone give me an idea of what happened?

I'm having this same problem and am looking everywhere for an answer. Hate to ask such a dumb question, but what do you mean by "make sure classic is turned off"? Are you talking about something in iTune preferences or something somewhere else? Thanks.

*Thank you!!!*

Wow, I never would have expected Classic to interfere with an iPhone update. I'd love to know how you figured this one out.
