activation lock screen bypass

Your options are somewhere between limited and none...

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

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 AppleID that was last used to activate the device, or unless you can secure the cooperation of the previous owner, you’ll not be able to defeat or bypass the Activation Lock. Without documentary evidence that you are the original owner (such as sales receipt showing the serial number), Apple won’t assist - and nobody here will be able to help you.

Basically none unfortunately.

"Activation Lock for iPhone, iPad, and iPod touch" is a security feature, in part to deter re-selling of stolen devices. To learn more click here --> http://support.apple.com/HT201365

An activation lock can only be removed using the log-in information for the account that applied the lock. If you know this information click on the link to read how to "Turn off Activation Lock." --> https://support.apple.com/HT201441

If you do not know the Apple ID and password and you are not the original owner, get the owner of the account to remove the lock or return the device for a refund. The device is otherwise useless to you. If the owner has not provided contact information as a message showing in the login screen there is no way to contact the owner unless the person who gave you the device knows them.

No, it's not possible. I'm afraid you have a paperweight.
