I can not update the firmware to the latest version. Conn. Kit and Virt. Calc. download and install OK but when it comes to updating firmware it gives the message "No firmware to update" even though the new firmware is unzipped in Firmware dir for Conn. Kit. This is the first time I have this problem.

Now nothing is works. Con. Kit stopped updating in the middle and hanged up waiting for connection. I think it is problem with a USB driver but I checked in Win 8.1 Device Manager and there is no conflicts. I do not see any HP USP driver either. Calculator boots but stops on the way so it is nonoperational. C-F-O, ON+SYMB, pin reset did not work and calc hangs when booting. I removed the batteries and hope this helps.
