Thank goodness, too! But yes, I managed to revive it by re-writing the entire ROM region.

The data abort message indicates there was an old newRPL version installed, which was properly detected (did you have newRPL or 2.15 before?), but somehow RAM memory was corrupted and the routine that verifies if your variable directories are consistent is having trouble to interpret the contents of your RAM (shouldn't, that's a bug I intend to correct, it should verify that pointer is valid before attempting to read from it).
The fact you cannot flash back 2.15 indicates the RAM is indeed corrupted, as even the bootloader relies on a few bytes of RAM to tell it what to do on boot. This is used by the calc OS (Hp one) to enter the diagnostic mode, etc.

I did have an older version, but had since restored to 2.15 for some time. I'll try to re-flash again.

Awesome! Many thanks for such an awesome project!
