If your iPad has the Home Button, perhaps you're not using the correct procedure (see point #1 AND point #2 at section: "Remove the passcode on an iPad that has a Home button" in the support guide I posted).

Try again.

If the issue still persists, contact Apple Support:--> Get Support

Your iPad2 is so old that it’s unlikely to be worth fixing. When (if) you recover your iPad, it will be wiped of all data and installed Apps.

As you may be aware, Apple ended update support for iPad2 in September 2016; iPad2 cannot be updated to iOS 10 or later versions, as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS.

Many App Developers have also dropped support for older devices and iOS versions preceding iOS11/12 - and some, for technical reasons, have dropped all support for versions prior to iOS/iPadOS 13. App Developers often withdraw older versions of their Apps from the Apple App Store - and following withdrawal, such Apps cannot be (re)downloaded or (re)installed. Loss of App Support for older models of iPad is making their utility and usefulness significantly more limited. 32-bit devices, such as iPad2, are effectively obsolete - with very few Apps remaining in the App Store.

If Apps that you need to use now have higher minimum iOS-version requirements than your iPad and installed version of iOS can support, your only option is to replace your iPad with newer model. Of current iPad models, even the basic iPad7 supports current iPadOS 13.x - and has hardware specifications that will vastly outperform your old iPad2.

I hope this is helpful to you
