RE: HP prime and HP39gii connectivity kit
The HP Prime and the HP 39gII both come with separate connectivity kits. The latest one (i think) for the HP 39gII is available at HPs FTP site - HP39gii Files. Do not install the HP39gII kit together with the HP Prime one on the same computer.

The kit includes a firmware updater (with a 5-page manual). The updater doesn't seem to work with WIN10 64-bit (Neither does the kit itself, it does not recognize connected calculators).

If you have the chance to get access to a WIN7 (32-bit preferred) computer, i recommend to use that for format and update.
  • Do not connect the calculator
  • Start the firmware update tool
  • Switch off the calculator
  • Connect the calculator while holding [ON/C]
  • The tool now hopefully detects the calulator and "Initializes..."
  • Mark the checkbox for "Format"
  • Start
  • Sit and Pray

I created a virtual machine with WIN7 and after several tries i managed to update my HP 39gII. It worked only after enabling USB2.0. With USB1 the "Initializing..." took ages and ended with "Please connect a device"
