Casio Calculators / Re: Upgrade fx9750GII to fx9860GII problem
« on: December 28, 2012, 10:36:42 pm »I had this same problem. When you get that error message, press the F2, AC/on, 4, and RESTART (on the back) buttons. Then release them. Next, press and release the 9 key, and press and release the x key (multiply key). Then try recovering the flash. Also, your calculator could be the new model (Power Graphic 2). Try recovering with the "2_02_0201_sh4.fls" file.
Thanks!! It's finally working =), I didn't know how to enter to the manual update!
