Disabled ipad

You need to be aware that we are seeing frequent reports of issues affecting (re)activation of 9 year old iPad2 devices when recovering from being disabled. If affected, and restart of your WiFi Router fails to resolve an activation issue, you will need to seek assistance directly from Apple Support. However, being so far out of support, you may hit difficulties.

Returning to your immediate problem, if your iPad is disabled, or you have forgotten your iPad passcode, you’ll need to follow this process:

https://support.apple.com/en-gb/HT211078

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).

You’ll also need your 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

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:

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:
