I can't unlock my Ipad mini even though I took it off from Icloud find my device, what should I do

Is the iPad disabled, or Activation Locked?

Activation Lock

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, 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 recently introduced a new portal though which you may be able to request release of an Activation Lock:

Disabled

If your iPad is disabled, or you have forgotten your iPad passcode, you’ll need to follow this process:

You’ll need access to either a PC (with iTunes installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS).

AppleID

You’ll need the AppleID and associated password. For which you’ll need the owner to assist. If these credentials have also been forgotten, they can be recovered by the owner 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

Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.

More information about recovery of your AppleID:

More information about recovery of your AppleID password:

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:

https://appleid.apple.com

If you intend to reuse the iPad with a different AppleID, you would be well advised to prepare it properly for reuse - as this will ensure that the Activation Lock associated with the original AppleID is removed, along with all data and other sensitive information:

Kaoki,

If you changed your Apple ID & password on that device, you need to remove the "activation lock" associated with the original Apple ID & password (the ones that were used to set up that iPad).

That's the only way to bypass an activation lock situation.

Shouldn't be this case, contact Apple Support, using this link:--> Contact Apple for help with Apple ID account security - Apple Support, and explain your problem.

What kind of "lock" have you encountered? What error message are you seeing?

Is it a new device, or a second-hand unit?
