I forget a passcode for my iPad Air (model A1474). After several unsuccessfull attempts to enter the passcode, it become locked permanently and asked me to connect it to iTunes. When I connect it to computer, iTunes says "iTunes could not connect to the iPad “Ilya V. Schurov’s iPad” because it is locked with a passcode. You must enter your passcode on the iPad before it can be used with iTunes." And iPad still doesn't allow me to enter passcode. I also turned off "find my ipad" feature and cannot erase iPad with iCloud.
So I finally decided to use Recovery mode. I followed the official instructions, entered the recovery mode and began the restore/update process. Unfortunately, to proceed, iTunes have to download iOS 10 which is about 2GB. It seems that Apple's servers are overloaded and iTunes says it will take about 24 hours to complete the download (or even more). However, as the documentation says,
If the download takes more than 15 minutes and your device exits recovery mode, let the download finish, then repeat these steps.
Indeed, after 15 minutes iPad exits recovery mode and restarts. The download is then stopped.
It is obvious that the repeating of these step will not help. Any other ideas how to restore iPad in this case?

This constantly happens to me and people I know.

~/Library/iTunes/iPad Software Updatesor~/Library/iTunes/iPhone Software Updatesdepending on device.The ipsw ought to be discovered automatically.
ipsw.me has links to all iOS versions, however generally only the latest is still being signed by Apple & will therefore be the only one that works for a restore.
