Hi, here we are again, now defeating the security measures of Nav5 devices !

The driver looks unsigned, which means windows is blocking it. as it doesn't allow unsigned drivers. A fix would be to go into windows test mode or try the Linux edl.py that was mentioned in the guide.

I really don't have an answer for this, it seems that Qualcomm drivers are there, check in device manager COM3 port comes out when you connect the device in EDL mode and that in the EDL folder where you run the .bat to make a backup copy there are all the files.

Hello everyone.
I have a problem with a tomtom go camper. Everything went as planned, the patch works perfectly, but the problem is that there is no truck attribute in (choose a type of vehicle). Has anyone already had this problem. Is there a solution.
Thank you so much.

Here are some pictures for more clarification.
