I installed the OS update for fx-9860G(slim) when my calculator was actually just the fx-9860G (NOT SLIM). this caused my screen display to turn upside down and the functions of my calculator's buttons to be entirely messed up. anyone knows how to solve this??

Hello rikrik97 and welcome to UCF! You should introduce yourself.

Can you install the OS update for the regular fx-9860?

[rikrik97]

no i cant,the screen is upside down, and when i try to connet to pc it says that the batteries is low, but the batteries is new (sorry for my english)

Your english is fine, don't worry.

You may want to call Casio about this since it is really their fault, the updater should check to make sure the proper calculator model is connected.

yeah but i dont think that i use a legal programe to update (fxRemote) i saw a video on youtube how to upgrade the os, and it works in fx 9750GII but in the fx 9860g sd, occured that error

Oh...


Well, then maybe cfxm or SimonLothar knows how to fix this.

Try posting about this on http://casiopeia.net, since that is where they can usually be contacted.

i saw this method and it works in the casio fx9750GII you know how to do this in casio fx 9860G SD?

"hold restart
+
Release restart
wait ~5 seconds
release +
Press
press "

that should also work on the FX9860, but if the keymapping is messed up, then you will have to figure out where the OS thinks those keys are.

[rikrik97]

yeah and i know where the os think the keys are, but this code doesnt work in this calculator

[flyingfisch]

hmm, i'm not sure. It's supposed to work when you do that, maybe the slim OS is different?

[rikrik97]

maybe, anyway thks for the help
