Question: iphone 3gs wont restore error 21

Hi

tonight I updated itunes to the latest version 9.2, then I check to see whether my actual iphone software needed to be updated. it said the new version available was the 4 one.

once it went to finish installing it said it couldn't be installed properly due to error 21. so after several times trying to get it to work I decided to restore.

but now it wont even restore cause the same error 21 keeps coming up. once I clicked restore it looks like its about to finish but then the error comes up then stops, now my phone is stuck with the itunes logo with the usb

cant get onto my phone at all and cant restore it dont know what to do, can someone help me out please or if anyone else had this problem could they advise me what they done

thanks
lindsay

Hi

I went into the apple shop in town they tried to do what I done last night and restore it but couldn't achieve it either and said it shouldn't he doing that and must have had a software problem there was also someone else in the store who had the same problem even tho my iPhone is only 3months old they replaced it and gave me brand new one! Try and go onto store I know you have to book a appointment but because it's a phone and they understand you need your phone they put you in a standby appointment

I waited 10mins and was seen. Hope that could help understand.

I've got exactly the same problem (error 21, won't restore), its really lame. Now I don't have my phone.

Reinstalled iTunes, nothing. Did all the stuff suggested, nothing.

Only plugged it in to have a look at the LP feature thing with the Chem Bros new album - now wasted a whole night and no phone, just cause I thought to update the OS.

Got a solution, on Windows Vista with 3GS phone.

I created a new user in the control panel, restarted, then logged in as the new user.

I then opened iTunes, which installs for the new user and then connected the phone. It then went through the OS software update no problems.

I stopped it at registering/setting up and switched back to my original user profile and it automatically restored from the back up.

Hope this helps - amazing how lost you feel when your phone packs in :-/

My friend, you are a legend!! Had my 3GS lock up after the 4.02 update. Was, after 3 hours, ready to pack it up and return it but after one final web search i found your golden nugget of advice and it worked a treat!!!

Thank you!!

Thanks a bunch. Just had the same problem as y'all after trying to update to the latest version of os 4. Came upon your tip pretty quickly so didn't spend too much time surfing the web but I assume I will still need to reload all the non-app content (i.e., music, video, pics etc.) which will take time but not as much as I would have sent so thanks again.
