    Casio fx-9750GII

Posted 04 March 2015 - 11:24 PM

I have just got a Casio FX-9750GII and was disappointed (like many) to find that there is no natural display option so wanted to flash a FX-9860 image. 

 

Firstly am I correct in believing that an OS Version 02.04.0701 means I have the GII-2 model and should be flashing the SH4 image.

 

Secondly I tried to "Backup flash" in fxRemote 2.0.21 and get "Error 04: Overwrite impossible/requested file does not exist. Backup is supported by Link/receive-mode only!" I am pretty sure that my drivers are working as I can copy programs to the calculator so does anybody have any idea what I could do to remedy this? (I could just flash the new image but I would like to make a backup before hand)

 

Here is the output from fxRemote:

00:00:00.002:FStart in
00:00:00.103:start...
00:00:00.103:...waiting for answer!

00:00:00.135:Flash transfer request...
00:00:00.135:...waiting for answer!
00:00:00.159:...waiting for answer!
00:00:00.160:...failed!

(Also I am completely new to the world of graphing calculators so please explain the specifics of things if possible, thanks (: )

    FX-9750 GII upgraded to FX-9860 GII

Download the fls file from here:

It's not working because you're using OS 2.04 and you're probably trying to update using the OS 2.02/2.01 files.

 

 

"Backup is supported by Link/receive-mode only!"

I think this is because you are just connecting the USB to your computer without putting it into the bootcode screen.

 

This is how to get it into the bootcode screen btw:

 

(**) Start bootcode OS updater: (GII models only)
- Press F2+4+[AC/on]+RESTART at the same time
- Release the RESTART button
- Release F2+4+[AC/on]
  * The display will be blank
  * for about five seconds and
  * then the OS should boot.
  * During this period:
- Press 9 and release it
- Press × and release it

 

Just use the files above with fxremote and put the calculator into the bootcode mode and then it should upgrade properly.
