    SM-G973W is a specific CSC – only for Canada.

    The bootloader for US and Canada is permanently locked and the “OEM unlock” is not going to be available in the “Settings -> Developer options”.

    That makes all of the above instructions pretty much fake 😉

      It does make it fake. Why even have it posted. I have a 973w and have tried everything in the book to get “OEM” TO SHOW UP IN SETTINGS. It can’t be done. I’m so,so,so disappointed in my Samsung S10 to the point that I don’t think I will ever spend the money on another Samsung device. Ever. I spent over $1000.00 Canadian dollars on a phone that I can’t do anything to. I love the looks and feel. The quality of the device. You can’t beat it. But what a let down when it comes to making it your own. Whats the big deal. Can’t they find a way to still take our
      Money with a customizable phone. We all know it comes down to the almighty dollar. OK. Thats enough, I’ll never buy another Samsung device until they give their heads a shake. I don’t expect it to happen soon. Thanks for selling me a phone that just upsets me when I stop to think about it.

      Samsung is a crap, they trace everything that you do, as the others. I don’t like them start pushing you to use their own software.
