iPad 2 iOS 9.3 can't activate

Hi,

I got the same problem with my iPad 2 WIFI.

I did the 9.3 update when it comes out, and since, my iPad is lock on the activation state.

Here's what I already tried :

1. Delete my iPad 2 from my iCloud.com account
2. Try updating it to 9.3.1 from iTunes (seems to not update at all since iTunes keep proposing the update every time I plugged the iPad)
3. Try to restore it via iTunes in recovery mode
4. Try to restore it via iTunes in DFU mode
5. Try to restore it with IPSW build number 13E237

But nothing works. Each times my iPad reboot, I always get the activation screen where I'm asked to enter my Apple ID.

I don't have any Apple Store near me. Plus, this iPad was bought two years ago, in a store that is closed today :/

I don't know what to do now with this iPad...

Anyone got an idea for me ?

Thank you.
