You may have run into a bug with iOS 12! Remember, iOS 12 is still in it’s early stages, and there are bound to be bugs and issues. Frankly I would just stick with iOS 11.4.1 until November-December wish and then try again.

I would downgrade as soon as possible with the guide below because Apple could stop signing iOS 11.4.1 any day now and when Apple stops signing an OS it is impossible to downgrade to an unsigned OS.

Hopefully it is just a software issue and the bug is patched after a while.

How do you reinstall an older system once a newer one has been instigated?

@mayer Not sure if that was a rhetorical question...

As long as Apple is still signing the older version, you can downgrade. As of right now, Apple is still signing 11.4.1. Downgrade instructions are here.

@refectio Yeah I was wondering the same thing, and thanks for adding the instructions!

@refectio I asked because it is almost impossible to downgrade a Mac system.

@mayer Umm, this isn’t a Mac we are working on here...
