Is it possible to restore an iPhone to a newer version of iOS that is not the latest? I would like to install iOS 11 on my iPhone 6 that has iOS 10, but the only possible update that I can see is directly to iOS 12.4.6. Can I update to a newer version that is not the latest?
The way I found is:


Download the desired image from https://ipsw.me/
Put the iPhone in recovery mode.
Open iTunes and Option + click (or Shift + click on Windows) on Update.
Locate the image and follow the instructions.
