I have this old motorola razr xt910 that still works just fine. LineageOS now has a rom for it so of cause I want to see if it's better then the older cyanogenmod. But back in the days of the razr, we ran safestrap because the bootloader was locked and motorola didn't release an unlock for my region or not at all. Lineage wiki page states to unlock the razr by official means or a third party. This got my thinking, if the bootloader is encrypted with an unknown key, how can third party software unlock it? There is no way I believe a simple local laptop can brute force it, so what else can such software do? So from a PC point of view, I would simply delete the partition and make a new. Now I know very little about android, so this might be blatantly obvious to others but why not just delete the bootloader partition and flash the one we want?
