my ipad 2 (older version) said if I connected my ipad to my computer I could use that to update my ipad.

The following has instructions on what to do after you connect it to the computer: If you see the Restore screen on your iPhone, iPad, or iPod touch - Apple Support

HELP!

Your iPad must be restored:

If you see the Restore screen on your iPhone, iPad, or iPod touch - Apple Support

These support pages outline the available methods to restore an iPad - either from a backup, or to Factory Settings:

Restore your iPhone, iPad or iPod touch from a backup – Apple Support

Restore your iPhone, iPad or iPod to factory settings – Apple Support

Restore all content to iPad from a backup - Apple Support

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).

Download and use iTunes for Windows – Apple Support

Update to the latest version of iTunes – Apple Support

Use of a PC or Mac computer is unavoidable. If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP) will be delighted to assist.

Note that the website I gave in my previous reply is where you are taken in you enter support.apple.com/ipad/restore into your browser.

If the other instructions in that support site don't work, see the Get more help section near the bottom of those instructions.
