Q: ipad2 failing to activate after udpaditng to IOS9.3

There seems to be an issue, especially with older devices. And I would guess that it's on Apple's end since it is affecting so many.

You can try to use iTunes to restore your device from backup

Or you could just wait it out and see if Apple fixes things.

Same thing happened to me, iOS 9.3 bricked my iPad2.  Will restore the device and post if it is a successful fix.

I would wait and see if they fix the problem.  I bet they will.  Because if you do not have a backup some where, you will not be able to restore your iPad.  The way things are right now, you have to restore your iPad to the factory settings and then restore your backup from iCloud.

The full restore process worked, iPad2 came alive again.  I had also a recent backup.  Happy again.

I have been able to finally get my iPad back.  I restored to my last back up on iCloud, but it is taking forever for all my apps to install.  I think someone's comment earlier might be the case.  Apple may be trying to get us all to purchase new iPad's . 

I cannot even get iTunes to recognise my iPad to do a restore.  It just tells me it cannot verify my device.  Did you get that and find a way round it?

This from another thread seems to be working...

Ok, that was a nerve wrecking day, but I managed to recover.

I restored my iPad with this procedure:

1. connect iPad to PC with iTunes
2. hold home and power button simultaneously for a long time. iPad switches off, switches on, Apple logo appears, and then finally the recover screen appears. Now you can release both buttons.
3. choose your recovery method. I chose full recovery, installed iOS9.3 and went for a blank (factory default) iPad.

Procedure took in total 30 minutes, including iOS download, reinstall and start-up iPad. But I have a fast internet connection. I can imagine it can take hours as mentioned in other posts if you have slow internet.

Phew !

Is your iTunes up to date? The drivers for the new iOS are included in the most recent iTunes update. That might help.

Apple just recently has offered this possible solution.

A solution for Activation Server Lock on iOS 9.3.
