CBR929RRY clocks

[Jerry6219Bug]

Hi,ive got a CBR929RRY that the rpm,lcd display wont work,the lcd has just the backlight on,rpm guage lights, but doesnt show rpm when started,all other lights ,indicators work fine. I hear this is a common problem,possible flash EEprom fault? if so anyone got a working file that i can use to reflash the chip? hopefully keeping the original millage.
Thank you.
