And I get confused about model lock again. When a device(not in that table) downgraded to its factory firmware, can I update a firmware that older than what is shipped with but newer than the factory one? If the answer is no, I understand the lock clearly. If yes, why not packaging images like Amazon? Just don't care about S/N, same device, same signed firmware.
People are far too human for that to work, even if it where technically possible.
Even the best of them can not be trusted to read and follow the directions.
Go look in the mirror for a handy example of that.

"Model locking" refers to the MODEL of the device, if it referred to the firmware version of the device, it would be called: "Version locking".
Technical English is funny that way, it means what is written, not what the reader desires.

You should NEVER try to install a firmware version older than what the model originally shipped with.
Amazon spent those $$$,$$$ developing the first firmware version for a specific model for a reason.
If they could have shipped the device with a version they already had, they would have done it.

WE DO package images like Amazon.
Amazon packages are model locked.
Our packages are model locked.
Amazon packages are cryptographically signed. (with their key)
Our packages are cryptographically signed. (with our key)
Both Amazon packages and our packages for years where both installed by the same Amazon provided installer (until the day MrPI became required).

For consumer firmware builds:
Just try to use an Amazon update package for a PW3 on your KV and see how far that gets you.
The package not being intended for the device will be deleted.
The only thing that will happen is you will have wasted your time and some electricity.

The "Factory-use-only" firmware builds are an exception.
They where built to be used only on the production line, for product testing.
They should NEVER have leaked out of the factory (but they did).
