Hello guys. I have been trying to understand more about Launch devices. It seems the license.dat file is being sent to the device when you try to run a brand. And the device itself decode the hash and check if the license is valid for this brand.

I have chatted with some russians and they seem they have un common one thing. If they have a license file for any brand like EOBD or any, they know how to create a license for different brands.

I guess this information was shared on some forums which i can't find.

Does anyone of your guys know how to do this?

Thank you
