Activation Lock issue on iPad

An Activation Lock cannot be bypassed.

Here are the Apple support pages that outline the Activation Lock - and the only mechanisms by which it can be satisfied:

Activation Lock for iPhone, iPad, and iPod touch - Apple Support

Turn off Activation Lock – Apple Support

As you will discover, unless you are the owner of the Apple Account (previously known as an AppleID) that was last used to activate the device, you’ll not be able to defeat or bypass the Activation Lock. With documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple may be prepared to assist - otherwise they and nobody here will be able to help you.

If you have the necessary documentation, Apple have introduced a portal though which you may be able to request release of an Activation Lock:

How to remove Activation Lock - Apple Support & start an Activation Lock support request.

Apple Account (AppleID)

You may also need your Apple Account (AppleID) and associated password. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:

• Your primary email address mailbox that corresponds with your AppleID
• Any of the secondary/recovery email addresses that should be configured for your AppleID account
• Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID

• Did you submit an Activation Lock removal request with Apple? Is so, was it approved?
• Was this an iPad purchased from Apple or third party?
• Was this your iPad where you forgot the Password to your Apple Account and see your partial email address on the screen?
• What changed to now show the Activation Lock?
