I've read and re-read forum postings (including responses to my own) pertaining to unlocking the boot loader. From these postings, it seems to me that the locked/unlocked state of the boot loader is not captured in the images in the various partitions that can be backed up, e.g., using fastboot. Basically, even the most complete backup that you do of the virgin phone, including the ISP's variation of the OS, does not include the locked/unlocked state of the boot loader. Can anyone please confirm the correctness of this understanding? Thanks.
