Initially the Windows 10 machine did not recognize the calculator in boot mode so I tried it on Windows 7. I think it may have been that I was either pressing reset too long or wasn't pressing the buttons consistently.

I like the idea of flashing the newest 12C for a dedicated 16C, all of the US shopping sites I checked, including hp.com, seem to have photos of older 12C versions. I know the Calculator Store has new 12Cs, does anyone know of a source in the US?

I initially had quite a time getting Windows to SEE the cable... After a while I figured out that that I was not actually in programming mode per se, so kept trying things after finding this forum and the post above. Eventually, Success! I hope my findings helps someone... though it seems most all of you did fine

Following the instructions provided on TCS, was my confusion...

Quote:Now, let's put the calculator in Programming Mode.
Put the calculator on (this is not required but helps to see if you are doing well)
To do that, press and keep pressed the ERASE button in the cable. Then press and release the RESET button. Release the ERASE button. ... The calculator screen should be off, but you should be able to see the device in the Device Manager of your computer. You should be now ready for the next steps.

The part that tripped me up was turning the calculator ON first...

Leaving the calculator off, and very quickly holding erase then pressing reset then release both fast did the trick...

Maybe break it out into two steps? "Step 1: In order to test that you are holding the buttons correctly, turn the calculator ON, [do the button steps], verify calculator turns off; then turn calculator on, see pr-error, turn off", "Step 2: ... generally as above", but point out that calculator won't mount/be recognized as a com device...?"

On my PC i also had to turn on "show hidden devices" under view; after that, I could see it, though it also shows up automatically in the SAM-BA app.

Otherwise, glorious, thanks TCS! (José)
