Note: The software also comes with an ROM Updater. You can use it to update the HP 39gII to 30/Oct/2013 Rev 19148 ROM.

Once the HP 39gII calculator is connected to your computer, you should be able to browse into the calculator as shown in following screen:

From Start Menu, select HP 39gII Connectivity Kit and then Firmware Updater.  You should see the the following dialog box, which is hunting for the HP 39gII connection. On the HP 39gII, press and hold the ON key and F4 key, and select option 9. for "Start Update.

The dialog box will change to "Initializing..." and the HP 39gII display will go blank with a tiny "hour glass" icon on the top of the screen.  Once it complete the initializing process, the "Start" button will be available. Next check the "Format Data Area" and then click the "Start" Button.  The dialog box will change to...

Wait for the process to complete.  Once completed, the dialog box will disappear and the HP 39gII will reset on its own and prompting the language selection.

Finally, press and hold the "ON" and "F4" keys to check the version of the Firmware. It should read something like "Ver: 30/Oct/2013 Rev: 19148".

    Hi, I can launch connectivity kit but cannot see any calculator content. I'm guessing it finds the calculator because with it unplugged I get a message saying can't find the calculator.
    The updater programme appears to do nothing at all.
    Can you help please?
    I'm using Windows 10, version 1709 by the way.

      I had the same problem (on windows 7). Update succeeded with standalone updater ( Be sure to check the readme file. After update the connectivity kit sees the calc. Good luck!

        Hi Rovamel, Thanks for your reply. I found a Win 7 (64-bit) computer and after many attempts was able to complete a firmware update. At that point the connectivity kit (running under Win 7) could see 39GII content but I could not save any changes to the calc. As the calc was a bit unstable (needed battery removals) I reformatted it. Stability much better now but still unable to save changes to calc content. I went back to my Win 10 computer and now I can change the calc's content and able to do a simple backup/restore, albeit manually! Putting all of the above aside; although I prefer RPN entry I do rather like the HP 39GII OS and programming language. (Reply)
