After press download and install update not start..!

I understand that you were attempting to update your iPhone and you could not get the update to begin the download process.

Make sure of the following-

• Connect to a WiFi Network
• Charge your iPhone to at least more than 50%
• Do not use a VPN Network
• Low Power Mode must be OFF

Try the update again after making sure that all of the above steps are verified.
