Upgrade Graph 25+Pro/35+/85 / fx-7400GII/9750GII/9860G/GII

Unread postby critor » 08 Feb 2017, 19:38

Preliminary checks and steps :
  • P0) Supported models :
    Check you have one of the following Casio models :
    • fx-9750GII
    • Graph 35+/35+E/75/75+/75+E/95/85(SD)
    • fx-9860G(SD)
    • fx-9860G Slim/AU/AU+
    • fx-9860GIIs
    • fx-9860GII(SD)
    • fx-7400GII SH3
    • Graph 25+Pro SH3
    If it's the case, you may upgrade it by installing an OS targeting a superior model in this same list ! :bj:

    If you have an fx-7400GII / Graph 25+Pro, check its processor type.
    :warning: SH4 fx-7400GII / Graph 25+Pro models can neither been upgraded nor updated. :#non#:
  • P1) Choose your OS upgrade :
    Recommended and compatible OS upgrades :

    If your model name appears in both last columns, then you have to determine its processor type.

    About the different exam modes :
    • French exam mode : no expiration, elapsed time cannot be checked, PRGM application not disabled
    • Generic exam mode : 12 hours expiration, elapsed time can be checked with
      ALPHA
      (-)
      , PRGM application disabled

  • P2) Elements needed :
    • a PC running Windows XP or newer
    • the right calculator to computer link cable :
      • if your calculator has an USB port, usually on the top-left corner as pictured, its USB(A)↔mini-USB(B) cable
      • if not, you'll have to use the mini-Jack 2.5 on the top-right corner, and will require a compatible USB(A)↔mini-Jack2.5 interface
        (for example, http://www.util-pocket.biz/catalog/prod ... cts_id=424 )
  • P3) Computer setup :
    If not already done, download and install the FA-124 linking software.
    This is going to install the calculator drivers too.


A) Get the OS upgrade image :
Get an image of the OS you'd like to upgrade to either from the Internet, or from a real calculator already running it.
In the later case :
  • borrow the calculator running the OS you'd like to upgrade to for some time
  • choose and download the appropriate backup tool :
    If needed, check your Boot Code.
  • right-click the downloaded zip file to extract its content to a real computer folder, and go into that folder
  • launch the right tool
  • connect the borrowed calculator to the computer
  • put your calculator in OS Error mode
  • click the Backup button in the tool window, type the file name and confirm
  • once the backup has completed, press the restart/P button on the back of the calculator


B) Patch the OS upgrade image for your model :
  • download the polyOS tool
  • right-click the downloaded zip file to extract its content to a real computer folder, and go into that folder
  • drag and drop your OS image on the polyos.exe file in that folder
    This should create in the same folder :
    • if supported, a file with the 2M suffix for an fx-7400GII / Graph 25+Pro/25+E calculator
      In that case, the OS being bigger than the model ROM, the tool may prompt you for the non-english languages you'd like to keep on the calculator.
    • a file with the 4M suffix for all other calculators


C) Prepare the computer to flash :
  • download and choose the appropriate fxRemote 2.03 flashing tool :
    • fxRemote2M4M if you are attempting to upgrade a fx-7400GII / Graph 25+Pro calculator
    • if not, fxRemoteE205 if your have an SH4 calculator with Boot Code 2011.0531.1709
    • for all other cases, the original fxRemote
    If needed, check your Boot Code.
  • right-click the downloaded zip file to extract its content to a real computer folder, and go into that folder
  • if your calculator has an USB port, now just run the right fxRemote
    if not, you need to identify your interface cable COM port :
    • start by listing your currently available COM ports :
      • be sure your interface cable is disconnected from the computer
      • launch the right fxRemote tool
      • in the cable zone, select the 3Pin option
      • if the option is greyed out, then your currently have no COM port
        if not, note the available COM ports in the then appearing drop-down menu
      • close fxRemote
    • now connect your interface cable to the computer
    • relist the now available COM ports :
      • relaunch fxRemote
      • in the cable zone, select the 3Pin option
      • note the available COM ports in the then appearing drop-down menu
      • close fxRemote
    • you should have found 1 additional COM port - that's your interface COM port, just select it
  • if you are attempting to upgrade a fx-7400GII / Graph 25+Pro calculator, check the "Recover Main memory backup area" option


D) Prepare the calculator to be flashed :
Put your calculator in OS Error mode.


E) Reflash the calculator :
  • in the fxRemote window, click the Recover button, and specify the right 2M/4M postfixed patched image.
  • Confirm the process.
  • Once and only once the process has completed and that the calculator has restarted and is back to the applications menu, press the restart or P button on its back.

Annex :
CPU type check :Go to top

  • type
    MENU
    , then go into the SYSTEM application
  • type
    F4
    to get the system version
    You should have the version string displayed as XX.XX.XXXX, with a digit in place of each X.
  • Look at the last digit, thus the 8th one with this format :
    • If it's a 0, then you have an SH3 model.
    • It it's a 1, then you have an SH4 model.

Thanks! I was actually writing a tutorial because I couldn't find one in English. Do you happen to have 2.09 for Slim?

Thank you. :)

2.09 is SH4 only and so won't work on the fx-9860G Slim.
You need an SH3 OS.

Ok. 2.08 hasn't been patched for the fx-9860G Slim different keys matrix.
You'd need to RE the currently available 2.04 patch and adapt it for 2.08.

Anyway, 2.04 is better than 2.08.
2.08 is removing the vectors support added with 2.04 (to comply with IB regulations), and thus is similar to the old 2.01. :P

No, not yet. I'm very busy this week. Believe it or not, I haven't changed anything to ControlX 4.4.1 since last week-end.
Even this Casio tutorial + the required polyOS v2 tool are just things already developed weeks ago.

Still, a notice to distinguish SH3 (SH7355/SH7337) from SH4 (SH7305) models would be nice ;)
