The steps are:
- downgrade FW from 0396 to P380;
- flash X381 firmware with Component Protection active/ static;
After removing Component Protection, I obtained Public key A6 2C 69 and activated:
- 10009006 MRR package 6: ACChigh (basic ACC) + FrontAssist incl. CityANB
- 10009301 AWV function extension package "EmergencyAssist"
(with 10009205 AWV pronunciation "AWV1,2,3, vFGS, vRFS" came from the factory).
Now I have errors on Engine, ABS and Auto Dist. Reg that I can't solve.
I don't know how to code ABS for ACC/ nor the cause of the errors on ACC (probably wrong coding)?
