You need version 2.00-2.01.

A version 2.02-2.04 means your calculator is using an SH4 CPU.
The fxRemote flashing tool doesn't support fx-7400GII calculators with the SH4 CPU.
And anyway, fx-9750/9860GII SH4 images are bigger and won't fit in your 2MiB ROM.

There is not any flashing tool available? Any one? Weren't we considering graph 35+ OS?

As already said, the only available flashing tool, fxRemote, doesn't support your hardware (fx-7400GII SH4).

Yes but SH4 versions of the Graph 35+OS, thus to be short versions 2.02 and newer, are bigger and won't fit in a 2MiB ROM chip anyway.
