How can I get a Natural Display on a fx-9750GII running 02.04.0701
« on: May 12, 2015, 01:12:27 am »
Hi, I recently purchased an fx-9750GII with 02.04.0701.  I would like to know if there is any way to get a natural display on this calculator.  I have tried with some flash images from older versions but they have not worked.  Thanks for any help.

Purchased an "Open Box" calculator from eBay...

Original Calculator: Casio FX-9750GII
Original OS: 02.04.0701  (No Spreadsheet, No Natural Display, No Addins support, etc.)

New Calculator (Functionality-wise): Casio FX-9860GII
New OS: 02.05.0201

UPDATE PROCEDURES (This is what I did... Proceed at your own risk... YMMV)

Installed CASIO FA-124 Application (CESG502 driver is required), verified USB communication, then exited program
http://edu.casio.com/education/support_software/

Found this utility to backup Original OS 2.04 (or 2.05)
http://www46.zippyshare.com/d/9f6bSkpF/779727/fxBackup.zip

Connected USB cable to PC, pressed [F1] to start DataTrans and "Receiving. . ." was shown on display
Ran the program "fxBackup_204.exe" and pressed [Backup flash] and typed a backup filename
Backup process was successful, program was exited, and (RESTART) pressed on the back of the calculator

Found this utility (fxRemote v2.0.3.25) "fxRemote.zip" to restore backup OS flash images to calculator
https://tiplanet.org/modules/archives/download.php?id=4484

Found this online discussion forum with loads of good references and links to information on this topic...
http://www.planet-casio.com/Fr/forums/topic9552-50-Transformer-Graph35+USB-en-Graph75.html

Connected USB cable to PC then pressed [OPTN] + [EXP] + [AC / ON] + (RESTART) (on back of calculator using stylus)
Released (RESTART) first and then [OPTN] + [EXP] + [AC / ON] to show "OS ERROR" on the display (contrast was very dark).

Ran the program "fxRemote.exe" and checked the box labeled "Delete storage memory" to make sure storage area was properly cleared
Pressed [Recover flash] and selected filename "os_205_9860g3.fls" and clicked through some dialog boxes to continue process
Restore process was successful, exited program, pressed [F1] to initialize storage area, and finally pressed (RESTART)

SUCCESS!!!

Ran CASIO FA-124 to load some Addins which all work, along with all other functions including Natural Display which is now default

At first was unable to restore original OS backup, but then found this utility that helped fix the issue

  Sorry if you said it in your post but where did you download the new OS for your calculator from?
