firmware problem

I put a new firmware on my Vectrix VX-1, cause I have the temperature light flashing and then unable to charge the batteries, but I have put new firmware on batterie charger and motor controller and ICM, I'm able to bring back the original version 3001 to the charger but unable to bring back the REV7-68 on motor controller and REV 1008 on my ICM. Can you help me to solve that probleme, and resolve the light temperature probleme.
