i managed to resolve 2:503, but i still get 2:004 and 2:101, i can't flash the truck type, i downloaded the parameters from another truck and there is par 1001, value 2, but here 1001 is grayed out, so i flashed the parameters from another truck, and still the same, the 1001 and all the factory parameters are greyed out, and can't be changed, but on the working truck parameter 1001 is not greyed....

and one more thing,the clock isn't going, it is as i left it, not counting the minutes...i think something is wrong in the MCU.
