Well thats a nice theory but do you yourself give guarantee to all models that they will keep working after such potentially destructive 'hack' ? I don't think so. Its trivial for manufacturer to make it stop working because of ie some security blah and just having a big warning on the screen to go to the repair shop.

So a typical internet advice - don't listen to it uncritically, or not at all.

Pull the fuse during your test drive maybe.
