Is there any way to prevent the Prime from formatting when something crashes it?

UPDATE 2: There was actually nothing wrong with the calculator. The same problem reappeared. So, I started installing app by app, backup and restore. I think I've found the culprit.

For some reason, even though the Control Systems app by Hata installs fine, if you back up the calculator with the app installed and then try to restore, the calculator crashes. This doesn't happen on the emulator. I hope others can try it and confirm.
