Does this mean that this is the only working method of obtaining certain information?
It is the guaranteed method
Only the sailors may know for sure now. And they might miss this topic here or be late to notice due to forum flood.
Looking at it is called Jolla 2, I suppose that it is going to have locked bootloader as Jolla 1. Other wise it will be C3.
No, it means that nobody even thought that somebody might ask such a question, and not accept the logical (even if guessed) answer.
Don’t bother to reply to me.
But ultimately that’s an Android term and I have no idea how the technicalities behind that term translate to SFOS on SFOS-specific hardware.
I already know it’s pointless, just after reading something like that. It’s not only an Android term, bootloader protection, safe environment, trust zone, and so one, all this things are security features supported by modern hardware, I assume any mature OS supports it and that means bootloader should be locked for default. And the question in main topic asks for possiblity of turning this thing off to get full control over device for any reason. So if you don’t know the answer it’s ok, I can wait for update from someone else which knows technical details.
