Anytime you perform a flash type operation to an electronic device, you run the risk of bricking said device. I used to go through this all the time as an IT professional. When we had to do BIOS upgrades on various components of say a server, router, firewall, switch, etc, we would chant in a halfway joking manner, "Please don't brick, please don't brick...."
That said, it's not the tune itself either. My buddy who is a BMW dealer tech told me when the upgrade kits came out for the 2G BMW Assist systems, he ran into a problem with the F chassis upgrade kits where the process of coding the new components were bricking things. It got so bad, BMW required the techs to connect up the systems to allow someone from BMW HQ to do the updates.
This is why dealers don't just upgrade DME software on your car unless there's a specific problem they're chasing which can be solved with a firmware update.
