Is doing an OTA the only way that your bootloader can be changed? I currently have bootloader 10.01 because I have not chosen to do the OTA from a month or two ago. I went from 2.1 to 2.3.9 leak to RubiX and then Apex ROM. Of course I currently use the 2.1 sbf when needed. I was just wondering if a sbf's can touch the bootloader? For instance, if I were to use the 2.3.15 sbf, would it update me to 2.3.15 OTA and change my bootloader to the 10.03 version with security keys, just like doing an OTA? Or would it give me 2.3.15 stock and bootloader 10.01? Or would the 2.3.15 sbf not work because in trying to flash it, RSDLight would see that I have the 10.01 and not the matching 10.03 bootloader? I am not planning on trying this to test it out, but I am curious about what might happen if I did. Also, is there any possibility of using a ROM based on newer android operating system versions changing my bootloader from 10.01? Since Apex is based on 2.3.15, I am quite sure the answer is no to this, but thought I would ask the question. Thanks in advance !
