HP Prime Firmware Update Problem

[Maestro]

Ok, I found where the firmware upgrade was removed from the FTP site, so I should reset to factory default. No problem, but I want to copy my data to the computer first. Since the touch screen doesn't work, I cannot use the send command. Also, the connectivity kit will not allow transferring files (throws an error).

I tried to reassign a button to a custom function ("SEND"), but apparently it doesn't work that way. Maybe there is something I am missing, but the prime just copies the returned text to the control line. I also had the idea that I could write a program on the emulator to send a matrix to a connected prime, but there is no "SEND" program command in HP PPL that I can find. Is there an internal name for the "SEND" soft button? If so, that would be perfect.

Bottom line, I just need a way to transfer data from a broken HP Prime to an emulator or computer. The only stipulations I know of are no touchscreen and no connectivity kit.

Thanks.
