So how long does the restore take for an iPad? Seems to be stuck for me

Assuming that your device has adequate free space (4GB+ recommended), the time required to perform a system restore will be principally determined by a number of factors:

• how much data must be restored
• the type of restore (restore to Factory Settings, or Restore from Backup)
• the type of backup - iCloud (requiring download) or iTunes (backup stored on local Windows PC or Mac computer)
• Restore to Factory Settings: the available bandwidth of your WiFi network/internet connection
• Restore from iCloud Backup: server load (noting that Apple’s servers are regional) and available bandwidth/speed of your WiFi network/internet connection.
• Restore from iTunes: the speed of the computer’s USB connection and available bandwidth/speed of your internet connection.

Larger downloads, or poor network connection bandwidth, will result is slower update/restore performance. If the restore process is not progressing after several hours, the process may have stalled - in which case it may be necessary to restart the iPad.

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

If you continue to experience difficulties, you may need to seek assistance directly from from Apple Support. You can contact the Support Team using the Support link at top-right or bottom-left of this page. Alternatively, if you have access to another Apple device, you can initiate and manage your support cases using the excellent Apple Support App. If not already installed, the App can be downloaded from the App Store:

You might also visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to assist:
