Q: iPad 2 won't activate and the solution offered doesn't work for me!!

I have a problem with activating my ipad 2 and I have tried the solution from the Apple website If you can’t activate your iPad 2 (GSM model) after you update to iOS 9.3 - Apple Support

but it didn't work for me, such as:

1. When I force restart my iPad, the screen didn't show the iTunes symbol on screen (and yes I restarted it while i was connected to iTunes)

2. This is what happen when i tried to connect my iPad to iTunes.

3. I tried to update it using "check for updates" and of course i chose "Update"

4. Finally this was happening when i chose "Update", I have tried to uplugged and reconnect my device, restart both my macbook and my iPad and no change whatsoever..

can anyone help please? this is so frustrating..
