HP prime and HP39gii connectivity kit

[olr]

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"
