I just got the HP Prime, and after doing a firmware update, I can’t press the combination «shift+matrix» or «shift+List», without the Prime rebooting instantly. I tried to reset my device, but it did not help. I also reinstalled the firmware, but no luck there either.
It is very annoying, and I can’t figure out whats going on.
Before you replied, I tried reset the prime again, and updated the firmware again. Then the list and matrix worked, but instead it it started rebooting whenever I tried to start making a new program. Every time I «check syntax» it rebooted. Also my HP Connectivity kit software on the pc crashed every time I cliked on the calculator icon.
So I uninstalled HP connectivity software from my pc, reset my Prime again, and reinstaled the software on my pc, re-installed the firmware update. Now, it seems to work. But I still have not tried accessing the calculator from the pc-software (purely out of fear for failure), so I do not know if that works yet.
BTW, by reset I mean factory reset (FCO-buttons) via the BIOS and reformatting memory.
