This method will supposedly stop working after April 26th, so do this while you can.
Write up on how this works from https://gist.github.com/dhinakg/035dc585a0de54b6a34cf72a2a36016e
If you futurerestored your device after Jan 26, 2021 to get to iOS 14, this method will most likely NOT work for you and you may see the “not connected to the internet” error. It appears this does not work on A14 devices
