how to open the activation lock for ipad

Hello:) You will not be able to activate iPad if you do not have the Apple ID and Password of previous owner. Sorry.Take a look below and return for a refund if you can.

Check for Activation Lock before you buy a device from someone else

Before you buy an iPhone, iPad or iPod touch from someone other than Apple or an authorised Apple reseller, make sure the device has been erased and is no longer linked to the previous owner’s account. Follow these steps to check if the device is ready to use: 

1. Turn on and unlock the device. 
2. If the passcode Lock Screen or the Home screen appears, the device hasn't been erased. Ask the seller to fully erase the device by going to Settings > General > Reset > Erase All Content and Settings. Don't take ownership of any used iPhone, iPad or iPod touch until it's been erased.
3. Begin the device setup process.
4. If you're asked for the previous owner’s Apple ID and password, the device is still linked to their account. Hand the device back to the seller and ask them to enter their password. If the previous owner isn't present, contact them as soon as possible and ask them to use a browser to remove the device from their account. Don't take ownership of any used iPhone, iPad or iPod touch until it has been removed from the previous owner’s account.

You will know that a device is ready for you to use when you're asked to "Set up your iPhone", "Set up your iPad" or "Set up your iPod" the first time you turn it on.
