Upgrading firmware, which changes code, and trying to keep prior settings that were for an older firmware is a recipe for problems.

Nope, they shouldn't need to do that. Their firmware is on another device different than the 4g flash part. What they have done is not be backwards compatible with their flash format change.
What they could do, is recognize the change in format and convert all the files to the new flash format when they boot. This could get nasty if the user powers off the device while the conversion is happening, but the worst thing that could happen is that they have to re-format (or simply invalidate) the whole flash part which they are already doing.
I've successfully done this sort of thing on more than one device that I've worked on. Not rocket science at all.
