I think that the update files are generated for one VIN number, so I am thinking about changing the VIN number in the car to the number of the donor or for which the USB flash drive is generated during the update. Change the number in the modules during the update and restore the original module...
The car whose VIN I wrote down is no longer complete, it was dismantled for parts. I bought GWM and APIM from this car, along with the installation, and I want to connect them at home and update them. I have a UCDS cable and it supports FRDS.
