So first uninstall itunes

Next, create a new account with Administrator access

SIGN OFF the original account (Make sure you are logged off or this will not work)

Sign into the new account

Download and install itunes

Put you iDevice into DFU

Restore and update your device

Once completed, delete the new account and reinstall iTunes on your original Account

If yu need to ever restore the same device that you had trouble with, follow these steps or it will fail again.

Hi,

I've had the same problem with my iPhone and iPad. This helped me! (i found it on a supportpage wich i can't remember because i tagged it in my iPad, wich is currently being restored)

1. You don't need to reboot Windows.

2. Leave your iPhone connected to your PC then:

3. Quit iTunes

4.1 In task manager click "show processes from all users", sort by description and kill everything "Apple".

4.2 Also kill the process with the image name AppleMobileDeviceHelper.exe

5. (xp) Click Start > Run > in the Open text box copy & paste the following - with the quotes - "%ProgramFiles(x86)%\Common Files\Apple\Mobile Device Support\AppleMobileDeviceHelper.exe" and press OK.

6. (win7) start> accessories > run > in the Open text box copy & paste the following - with the quotes - "%ProgramFiles(x86)%\Common Files\Apple\Mobile Device Support\AppleMobileDeviceHelper.exe" and press OK.

7. Open iTunes

Good luck!

i get error -1 😟

I got error on windows.I followed the below steps.

Kill all Apple process in Task Manager

Right click the ittune application.

Choose run as administrator.

It worked like charm

Exactly the same thing happened to me today in an Apple Store in Munich... they offered me a 30% discount + a 81€ discount... I refused this offer as I didn't do anything wrong: Apple suggests an update, you do it... and my perfect working iPad 2 is now a chopping board. It's like if I take the car to the mechanic cause he suggests to check the oil level, and I get it back not working...! I'm super unhappy... I'll try to call the Apple Care and see what they say, as it wasn't my fault.

any update for Ipad 2 the ipad "ipad" could not be updated. an unknown error occurred (-1), because until know I can't use my Ipad 2.

Please share the solution for this problem.
