Been REALLY busy lately so late to the update group
My beta model, which is my in use calculator updated via the Quick Update procedure very easily.
My production unit which was last updated to 3.12 will not update via the Quick Update procedure.
It connects correctly becoming a USB disk on my laptop. I copy the 3.15 code to the root directly as in my Beta Unit. I disconnect and follow the flash firmware from FAT steps.
At this point the calc just freezes with the flash firmware from FAT screen.
Only a reset works which resets to the 3.12 firmware and the 3.15 firmware resident in the root directory.
new battery,
Connected and not connected
Delete and recopy to root via USB
Just stops at the flash firmware from FAT screen .
Any ideas or do I have to do this the old fashioned way?
Cheers
P.s. the beta calculator flashed perfectly following the above procedure:
USB
Firmware to root
Execute “flash firmware from FAT screen.
(Probably missing something blindingly obviously
