Casio has released OS 2.01 for the FX-9860G and FX-9860GII a few days ago. It features enhancment of polynomial and discontinuous function calculation. According to cfxm, it also apparently fixes (http://www.casiocalc.org?s=&showtopic=5606&view=findpost&p=51501) an issue that was present on OS 2.00, but not on the PRIZM. (Let's hope it doesn't introduce the Locate glitch from the PRIZM...)
Apparently it is also possible to install this OS on a Casio FX-9860G Slim too, using SimonLothar's Slim GII Mod tutorial (http://casiokingdom.org/modules.php?name=Forums&file=viewtopic&t=1459). Normally the Slim can only run OS'es from the 1.x branch, as there are no OS 2.x available on Casio server for that model.
OS 2.01 was also released for the fx-9860GII/fx-9860G Manager emulator series.

I tried to update my 9750gii hacked into a 9860gii and it wouldn't send... :(
I'll try it the old way, creating the OS error that hacked it up originally.
EDIT: can the os be extracted from the new update, like said in the hack PDF (http://casio.bank.free.fr/modules/archives/downloads/G35PUSBupgrade.pdf)?
-
Wait I thought you managed to do it with OS 2.00 a while ago? ??? Is it just with 2.01 that you got problems? Maybe once you hacked your calc, there's no way to update anymore?
-
The OS update is in an exe, which casio uses some method to send. What I would need is a way to isolate the file or whatever the hack uses.
-
Oh ok. There might be some info about this in the Prizm section, but this might not necessarily apply to the older models.
-
I guess I'll just abide with 2.0 until one of the casio leets finds this thread :P
So...
It features enhancment of polynomial and discontinuous function calculation.
What exactly does this mean? I'm not too strong with math terms :P
-
polynomial function is the function that has x^n terms and discontinuous function is i think that the function that doesnt connect in graph.
So DJ, does that mean that Prizm doesnt connect the discontinuous graph unlike some old TI calc?
-
Nice to see that Casio still updates the fx 9860g. Even better that these are real OS updates that fix bugs and aren't like what TI does with 84+ 2.53 and 2.55. Unfortunately Casio hasn't fixed any of the Prizm bugs or really done anything new at all there since January.

Normally the Slim can only run OS'es from the 1.x branch, as there are no OS 2.x available on Casio server for that model.
If I'm not mistaken, a 2.00 OS for the fx-9860G Slim had been released on Casio server and then removed...
It's on Casio-Bank:
http://casio.bank.free.fr/index.php?mod=archives&ac=voir&id=128
But it's very similar with the fx-9860G 2.00 OS.
So you won't get the GII features like that.
-
Can someone explain how one who turned their 9750gii into a 9860gii (http://ourl.ca/8784) would be able to upgrade to 2.0.1? I tried sending it using the application available on Casio's website and it said "model not supported."
-
If it works anything like chameleon, you'll need a custom OS, like you probably used in the tutorial. Are these OSes signed? That would be my first guess as to why it fails.

Oh ok. I wonder why they did remove it ???
-
Maybe they found out a fatal flaw in it, and decided to fix it.
BTW, did OS 3.2 nspire actually fix the boot2 problem? or is it just Lua removal?
-
Yeah, but OS 2.00 was out for 2 years. It means it has been gone for a loooong while.
As for OS 3.0.2, it fixed the boot2 issue, but it added an anti-TNOC downgrade breaking protection, meaning once you got OS 3.0.2 installed, you'll never be able to downgrade again, even after using TNOC. It also adds encryption so only Lua files from OS 3.0.1 can be ran on 3.0.2, not ones generated by computer tools.
-

Lua files from TI also work, but I think we expected that. :P
-
Yeah true. They definitively either wanted to make Lua only available for full use by them, not us, or they want to release a paid SDK to make money from us...

The way it happens is you cause an OS error, and send the desired OS using special link software or something (it's been a while). The hardware is the same--with the update it's just used, when before some things weren't. The trouble is, the update from the Casio site is packaged together with pc-calc linking stuff in an exe, and the OS has to be isolated iirc.

You need Simon's updater available here: http://www.casiocalc.org/?showtopic=5606
Oh ok. I wonder why they did remove it ???
As far as I know, there was some trouble with Asian countries, because OS 2.00 has features which are not allowed there and as Asia is the Slim's main market, they had to remove it.

I downloaded 2.0 for Slim from here http://casio.bank.free.fr/index.php?mod=archives&ac=voir&id=128
I clicked on "Telecharger" Is this the (magical) file I need? (OS 2.0 string support and cool random number functions)
And is this file in English?

Absolutely yes! :)

Yay woo! Now to get string support and fun stuff on my calc! :D

Awesomeness. Will do.
EDIT: would it be legal to attach the .fls to a post here or something so people don't have to wait through the so-called rapidshare?
EDIT2: done! I had to do the trick here (http://www.casiocalc.org/index.php?showtopic=4959&view=findpost&p=49614) then send it through pfxrecover, but it worked!
:w00t:
EDIT3: fixed link in edit2, went to wrong post :P

Good job! Especially because you do not own a slim. Respect.
-
Wow nice to hear.
I wonder if Casio has plans to ever make OS 2.01 available for the Slim in the future?
-
A bug in the Slim GetKey routine was discovered and fixed.
All people shall update their Slim again.
-
New update is awesome, btw. MP-style input in the equation solver and Y= screen ;D

Cool to hear it was spotted and fixed :)
