DM15 firmware update failureS

[sjthomas]

[Ignore -- All the firmware flashing mucking about I was doing caused the battery in both units to go completely flat. Re-replacing them did the trick. D'OH!]

Hello All,

I have two DM-15’s which I was attempting to update the firmware. I tried one using Windows 7, and the other using Mac High Sierra. Unfortunately, I have run into the same problem with both: The flash process starts, but after 7 lines, errors with the message “Program Too Large — running out of flash sectors.” And although the instructions on the website say “it is not possible to break or brick the calculator,” it seems that is what has happened. I can not get either unit to do anything, not even power on.

Batteries are fresh. All drivers installed on the computers without issue. Using a good quality shielded miniUSB cable.

Would appreciate any helpful suggestions.
