iPad crashed during OS update and now iTunes can't restore

I tried to update the OS on the iPad today and about 10% of the way into the installation, the installation failed. Got an error screen saying I would need to do a restore. I was also referred to a help site at support.apple.com/kb/TS1275.

Even more disturbing is that the info in iTunes for the iPad shows "n/a" for the name, capacity, OS version, or serial number. This information showed when I first got the iPad.

I tried a restore and it went through the following steps:
extracting software
verifying iPad restore with Apple
Checking with Apple
preparing for restore
waiting for iPad
a progress bar shows on the iPad but in a few seconds I got the error of iPad could not be restored because of an unknown error of 9

subsequent restore attempts get to the progress bar, but then tells me the device can no be found

I have tried the 2 button restart of the iPad but that has not helped

I have made a copy of my last good iPad back up and have it in reserve if/when needed. Fortunately I do daily syncing of the iPad

Is there a forum solution or is this an Apple solution?

After 10 attempts to restore and 5 restarts, I finally got the iPad to be found and respond. I am now trying to get everything arranged back the way it was. iOS 4.3 got installed and the capacity, size and serial number are back.

Which apps were loaded, and their arrangement is NOT restored and this can be very tedious. Everything was unchecked in iTunes.

Not happy, but i am the road back to where things were.

An additional observation after another updater failure. Do NOT update on a shared USB port. I have a USB dongle to let let multiple USB devices be on one port. This will not work. Plug iPad directly into a USB port or it will probably fail. This is probably the same reason you can't plug into a keyboard USB port as not enough power to run the operation.

I just solved my problem here.

IPad 2 was frozen with the apple logo and progress bar, during iOS5 update, using Windows 7 64bit.


I pulled the cable - that's when I started looking around for solutions.

Hard Reset the iPad - press and hold power and menu buttons for about 7 seconds. Fortunately it worked, going back to factory settings (awaiting to be plugged to iTunes)


Updated the iTunes SW.


Entered my Firewall suite settings (Avast 6) and disabled both firewall and real-time shields.

Plugged the iPad to a single USB port (not a hub).


This time iTunes recognized it, restored the backup and applied the update.

All good.
