Very interesting post, thanks for writing it!

So the protection should be at the code / firmware level only, right? As all units are supposed to receive the same firmwares (either on the factory, before leaving to retailers, or when doing an OTA upgrade) - how come some seem to be downgradable while other aren't?

What about 5.8.9.0.1? The protection isn't enabled at all on this one?
