    Hello,
    I flashed my Samsung S7 edge to custom ROM, Later i decided to go with the Stock ROM and done so, but seems still the bootloader is unlocked.
    I want to re-Lock by bootloader again, can some one help on how to do that ?
    Thanks

    curious as to why? There's really no need to re- lock it. plus by rooting, you have already tripped Knox and there is no way to un-trip Knox.

    Thanks for the response, I have an compelling reason to do that, which is my office work profile (office emails) have stopped working because of the bootloader unlock.
    Any help on how to lock back will be very helpful.

    ok snapdragon processor then the guide I kind in my last post should get you relocked using adb and fastboot commands. but also please read the second link as well. it mentions that you need to be on a stock rom before you re-lock the bootloader.

    Seems there is no option for going into fastboot mode in this model (SM-G935FD), I am not sure if I am missing something here

    all phones should have a fastboot mode.......never heard of a phone not having one.

    @ocnbrze Nope, Samsung phones don't have fastboot mode. Furthermore, they don't even have a locked bootloader. Doesn't mean you can just flash anything, but there simply is no "relock".
