iPad stuck at activation

[Wronger007]

I have 16g iPad air 2 WIFI+ Cell with broken screen, I was trying to sell it, so I logged out from iCloud and started resting and formatting it, after that finished, I found out the iPad couldn’t be activated saying " your iPad couldn't be activated because the activation server cannot be reached".
I tried restoring or updating it by putting in recovery mode but no success, I have a log for the iTunes error

You need to contact Apple support to see why it's not talking to the server. You are connected to WiFi when you are trying to do this correct?
