My Radias doesn't boot correctly anymore. It' display freezes while DRUM module is loading. Checksum Error message is displayed. Do you know any way this can be fixed? Maybe reloading system can help or so...
Any suggestions . I appreciate your help !

I asked michu how the repair happened. This is what they said:

I ordered part from korg (Parts is Parts) long time ago.
It was special order Part No 500320012346.
Korg FLASH (NOR) S29JL032H70TFI020D(X5260)


I replaced flash chip myself on Radias CPU board.
It required some practice in micro soldering and temp control.
Doable if you practice on a piece of old computer hardware.
I'll try to describe it on korg forum when find time for that.
