I'm continuing this thread.
I need some help on this from someone that has re-flashed their DM-15CC calculator.
I can't quite figure out what procedures are needed for flashing. I've installed the drivers for the CP210x and got it working on a COM port. I've download and installed FlashMagic as well as the needed hex files. What options need to be selected within FlashMagic and when do you need to press and hold the internal programming button (through the tiny hole in the back of the calculator)?
Thanks,
Katie
