Title: Upgrading a fx-9750GII to have nautural display
Post by: Cait Rob on April 12, 2013, 03:20:46 am
I have a casio fx-9750gII calculator with the version 02.02.0701
I was wondering if someone could give me the links and directions to make it so my calculator could have natural view.
I saw some people in my calc class have it and it seemed to make their lives easier and decided to try get it too. I saw a video about it on youtube but i cannot get the links anymore.

Yeah, the links seem to have been taken down when some websites were switching around. :/
(I'm assuming you mean this (http://www.youtube.com/watch?v=S2gVq4J2vdA)?)
I think I might still have the translated version of the instructions somewhere, but the links will need some digging. That or it might be on TI-Planet..idk.

Edit: don't have it anymore, sorry
Edit2: Stefan found this: http://tiplanet.org/forum/archives_voir.php?id=4489
Might have to google translate it yourself, but the links are updated so they should work. :)

yeah that was the youtube video i saw,
i downloaded the casio FA-124 but i couldn't find a place to download the flash file.
The video that we both saw said that it'll only work with version 02.00.0700, will the download from the website you showed me work with the version i have?

Post by: Cait Rob on April 12, 2013, 07:31:47 am
i tried downloading the links and installing the files onto my calculator but it says my calculator model is not supported.
is this because it is version 02.02.0701?

Maybe a help too? He says he has your version, so I guess it works with yours too.

i got to this step here

flash images
this step is important, and decides whether your calculator lives or dies. there may be sorts of error prompts.
enter “BIOS” screen for the calculator; connect the calculator to a PC with the usb driver; better kill the FA_124 process (or close FA-124); run the tool.
“backup” means saving the current system as a file on your computer, for restoration later. “restore” means to flash a system image into the flash storage of the calculator. i suggest to first backup your current system, then flash your own system image back. if everything goes fine, and your calculator (hopefully – ) did not die, carry on and flash an appropriate fx-9860 system image. choose the .fls file, whose name corresponds with your calculator’s version. for example, my calculator has the version 02.02.0701, which starts with 02.02, i simply choose the tool “fxRemote”, and eventually flash the “2_02_0201_sh4.fls”
 from http://blog.easoncxz.com/?p=25

but i can't find where he got the flash files from.

I remember the files used to be hosted on Casiocalc for a while, but then the admin took them down because the package or files themselves included copyrighted material. I sadly can't help much, though, since I only got the old 9750G+ from 2003.
Title: Re: Upgrading a fx-9750GII to have nautural display
Post by: Darl181 on April 12, 2013, 06:57:56 pm
Iirc you get the .fls off of the calc with pfxrecover, and use one of the programs (PolyOS?) to patch it.

Post by: Cait Rob on April 12, 2013, 07:24:49 pm
sorry Darl i don't really understand what you said, but is there a way for me to download this 2_02_0201_sh4.fls flash?
Title: Re: Upgrading a fx-9750GII to have nautural display
Post by: Darl181 on April 12, 2013, 08:00:39 pm
Not as far as I can tell. :/ Looking at it closely this guy just translated an already-existing document without the links..

What does your calc say on the front? Does it say "USB Power Graphic" under the screen or "USB Power Graphic 2"?
Title: Re: Upgrading a fx-9750GII to have nautural display
Post by: Cait Rob on April 12, 2013, 08:06:58 pm
USB power graphic
Title: Re: Upgrading a fx-9750GII to have nautural display
Post by: Darl181 on April 12, 2013, 08:22:50 pm
With no 2 after it? And yet it's the newer version..this is strange.
Best I can think of atm is what you've already done, asking the guy in the blog post to send the files like he said and hoping he sends it. :/
Title: Re: Upgrading a fx-9750GII to have nautural display
Post by: Cait Rob on April 12, 2013, 08:25:36 pm
yeah it the Casio fx-9750gii the one with the blue surrounded by white design,
I don't think  i will get a response from the person who wrote the blog though,

it's also different from the person who made the youtube video because it's version 02.02.0701

"Try to backup your calculator – this ensures that the tool is working, and also to get an image of your stock system. Try restoring your stock image – this ensures that the restore function is working. At last, restore an fx-9860GII image that comes with the tool and has a filename that corresponds with your version."
from http://blog.easoncxz.com/?p=25
it says there's a verison of the new calculator's flash already loaded with the tool but i can't seem to find it.

Post by: Darl181 on April 12, 2013, 09:09:42 pm
I can't seem to find it either..the one version of fxremote I can find doesn't have the other files.
Looks like the topic containing the downloads originally was taken down. Maybe try contacting the developers to see if they'll send you a copy? Idk if it'll be possible beyond that, unless you find someone else with the files and get them to send it.
Title: Re: Upgrading a fx-9750GII to have nautural display

It means flashing the fx-9860Gii 2.02 operating system thanks to a 3rd party tool.
2.01 operating systems and older won't work in your case.

Hello, sorry for kinda bumping this old thread.
I just bought an fx-9750gii and it only says "USB power graphics". However if I check the version number in the calculator it says I got version: 02.04.0701
I've been trying for a while now with upgrading the calculator so that I can get the natural display that I really cannot live without.
I've managed to find two files from some guy’s dropbox account with the names of:
2_04_0200_sh4.fls
2_04_0200_sh3.fls
Those files should be the right ones, right?

But still every time I use fxRemote.exe to update I get the following message on my calculator:
Code: [Select]
OS not identifiable!
Start bootcode
OS update
manually and try again.
I also get these logs (see picture) and fxRemote crashes.

However I think my problem could be rooted in the following step described on the blog linked before in this thread:

Quote from: blog.easoncxz.com/?p=538
This step is both tricky and necessary.
in order to let the tool acccess the flash memory of the calculator which stores the system, sort of a BIOS screen is to be entered. check that the RESET button is functioning before proceeding. turn off the calculator, and press the following key sequence. “+” means press and hold, “-” means release, “()” means at the same time, ”     ” means wait for half a second or so:


Code: [Select]
+RESET+F2+4+AC-RESET-(F2+4+AC)+×   -×+9   -9now the screen should have a contrast error, and show the words “OS error. Please update OS.”. this is the “BIOS” screen. with this screen showing, and with the calculator being connected to a computer with the usb driver properly installed, and with the tool run as administrator, the tool can read or write the calculator’s flash storage in which the system lies. sd

Is my problem merely that I’m just to unskillfull or/and dumb to be able to successfully enter that code? Do you guys have any tips for entering the code successfully?

Thanks in advance.

Stop all upgrading activities.

We need to backup this OS first because it is new and we don't have a copy yet.
However, this is a bit more complicated and I will let you know when we have a clue how to do it.

If there is any way I can help, please tell me!
Maybe you guys could guide me in backing up my OS (v 02.04.0701) so that I can upload it too you guys.


Also if there is any need for these files:
2_04_0200_sh4.fls
2_04_0200_sh3.fls


They can be found in this dropbox link (can be found in comment section), posted by +Julio Molero (https://youtube.com/user/jcmolero71?feature=hovercard), on this youtube clip (Search for: Casio fx-9750gii to fx-9860gii OS upgrade by DanoninoBG).

He aqui los archivos del 2.04: redacted
el SH3 para toda la familia fx-9860G (menos slim) y el fx-9750GII con SH3
el SH4 para el fx-9750GII con SH4 únicamente
el slim aun queda pendiente
usar ùnicamente con el fx_mod.zip de la descripción, el fxrecover no los leera, de hecho aconsejaria usar unicamente el fxremote para todo ya que puede usar las prmeras 9860 tambien (la mia es la mas vieja segun la fecha de estampado visto en el documento de fxremote, 2005.0511.1748)


Unfortunately I can't read Spanish, especially not this comment due to myself being a noob on the topic. Maybe you guys can understand it better when in i'ts context.


I've scanned the files and they seem to be safe.

Hi,

Please remove these links - they are not allowed in this forum.

The OS 2.04 cannot be easily backed up as Casio has disabled some functionality. But we are working on this.
Could you send me your email address via PM? Thanks.

Very unlikely. You are the first person who I know of that reported a preinstalled OS 2.04 on an fx-9750GII. We didn't even know whether Casio had compiled such OSes.

Yep, you're right, those .zip's didn't contain the backup of fx-9750GII OS v2.04.

Contents were as following:

Code: (fx_mod_orig_os.zip) [Select]
fx-9860G slim 2.00.bin
fx-9860G(SD)1.05.bin
fx-9860G(SD)2.00.bin

fx-9860GII(SD)2.01.bin

Code: (fx_mod_slim_by_cfxm.zip) [Select]

If any of that is interesting, just throw me a PM.

If you guys want a copy of the OS 2.04 you should be fairly quick about it.
I'm gonna turn in my fx-9750GII for another graphing/MAT calculator with natural display later this week.

I think it's so saddening that the fx-9750GII doesn't have natural display, or that I can't seem to upgrade mine because of this new OS release, because I really prefer the fx-9750GII over the more advanced series of calculators. I really prefer both the aesthetics and the button-layout of the fx-9750GII over the more advanced ones. It's slim and not so bulky and has nice colors and button-layout. I've always had the FX-82ES Plus, which I've just loved, mostly because it's natural display and layout. I choose the fx-9750GII because of the similarities and the fact that I don't really need the more advanced functions. However I'm not going to live without the natural display so I guess that's just how it is.

What do you guys think? Which one do you recommend, or should I keep my fx-9750GII for a little bit longer while waiting for a fix?

Upgrading your fx-9750GII should still work with some small modifications, but I won't tell you what these changes are until we have a copy of the OS and this still requires some amount of work to be done.

Hi all,

Sorry to bump an old thread, but I have too fallen in to casio's lack of natural display trap.
I'm running the fx 9750gii @ version 02.04.0701 and on the front it reads usb power graphic; it's the blue one with the White case.
I'm desperate to get the firmware swapped out on it to one with the natural display. I believe that someone has done it, and I really need them to help me.

Please contact me if you know anything. I can't live without natural display!
