Hi everyone
I have a Casio FX-9860G AU and its displaying some kind of OS issue.
I have attempted to update it and it just hangs at 100% on the computer screen and says updating on the calculator.
I have run a diagnostic test via the service menu and the OS comes up as a NG, I have tried flashing at both the standard on screen and via the emergency flashing point, both seem to do the same.
Can anyone shed some light on this?
Any help will be appreciated.
Thanks
Scott
