software problem

I am not able to either switch it on or switch it off. There is one message displayed i.e. support.apple.com/ipad/restore and one image of laptop and one image of data cable. I have tried to updatefrom iTune by connceting the ipad to a laptop. However it couldn't be updated and error is being displayed "The iPad couldn't be updaed. An unknown error occured (4013)". Pls help me.

iPad, iPadOS 15

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.
