Ipad Pro 2nd gen disabled despite all attempts

Okay, the last available recovery method is a DFU Restore.

Entering and using DFU mode with iPad requires a computer with iTunes, a USB cable, and any iPad with a HOME button. Here’s what you need to do:

1. Plug the iPad into your computer
2. Launch iTunes on the computer
3. Hold down the Power button and the Home button at the same time
4. Keep holding both of these buttons for 10 seconds
5. After 10 seconds pass, release the Power button but continue to hold the Home button for another 3-5 seconds
6. iTunes will notify you that it has detected a device in recovery mode, you should now be able to restore.

IMPORTANT: When in DFU mode, your iPad screen will stay completely black. If you see an Apple logo or otherwise you did not enter DFU mode, so you would need to start over again. If you see an Apple logo or iTunes logo, you probably entered Recovery Mode which we tried earlier.

In DFU mode the screen remains black.

If this doesn’t work for you, I’m out of ideas and you’ll need to contact Apple Support. As you purchased the iPad from eBay, I have no idea if Apple will provide free support or not. If help is available, you may be charged.

You’ll find the link to Contact Support at top-right of this page.

Your additional comments would perhaps lead to this procedure:

Critically, ensure that your PC has the latest version of iTunes installed.

Check and verify all these steps:

Have you attempted the restore to factory settings procedure linked in my last reply?

So the problem is now resolved?

Purchasing a used device from anywhere other than Apple is fraught with risk - but assuming that the device was correctly prepared for reuse prior to its resale - we need to establish what is locked/disabled and move from there.

If you device is disabled because you have either forgotten or successively entered the incorrect passcode, you’ll need to follow this procedure:

However, if your iPad is indicating that it is Activation Locked and you have forgotten your AppleID or password, you’ll need to recover them:

More information about Activation Lock and associated procedures can be found here:

If, by chance, the iPad was not prepared correctly prior to resale to you - and the AppleID corresponding to the Activation Lock is not yours AppleID, then you’ll need to secure the cooperation of the previous owner - as only they will be able to release the Activation Lock. In this circumstance, if the previous owner cannot be contacted, it’s “game-over” as there is no way to bypass the lock.

Good. If the Activation Lock is not an issue, you may be in a relatively good position to resolve any issues. If the iPad was successfully “activated” using your daughters AppleID, all recovery steps should be within your control.

Remediation of an Activation Lock, by a third-party, is only an issue if the iPad was not properly prepared and released from the account of the previous owner - as so often happens.

Ignoring the references to Activation Lock, if the other procedures did not resolve the problem, I recommend starting again. A full system restore will wipe the device, load a fresh copy of the highest version of iOS/iPadOS supported by the device, and reset to factory settings:

After running this procedure, you will effectively start again from scratch. As you believe that activation was previously successful using your daughters AppleID, you will encounter the Activation Lock - but have the means to provide the necessary credentials.

I hope this is helpful in resolving your problems.
