HP-48/49/50 emulation on iOS

[jburns]

Like everyone else in this discussion I was horrified to find when I upgraded from an iPhone 7 to an iPhone 12 that m48+ is no longer working.

I upgraded phones because I changed service providers, and they will give me $530 for my old phone that is only worth about $50. I have to turn in the old phone in just a few days. I have used iMazing to do a full backup of the old phone and have saved m48+.imazingapp. What else should I do before sending in the phone? I would like to eventually be able to recover my configuration of m48+.

I also have m48+ on an old iPod.

From reading this discussion it appears it is not possible to use these old files to install on my new phone. Am I missing something?
