I made update with my IPAD 2 GSM ( IOS 9.3 ) and was locked on "Server update" ...
My IPAD was absolutly lock !
Every test by ITunes or ICloud did'nt not solve problem.
But for IPAD 2 GSM, I tested this solution and it's OK !! :
If you can’t activate your iPad 2 (GSM model) after you update to iOS 9.3 - Apple Support
Hope for You.
Best regards.
iPad 2, iOS 9.3
