  1. I’m sorry, doesn’t OEM unlock have to be enabled BEFORE you can flash firmware? I don’t understand how Method 3 is even possible.

    • Yes you can certainly flash any Stock ROM on your device, bootloader unlocking is not required for that. Bootloader unlocking is required if you only need to use custom ROM or custom kernel.

      Thanks for the notice, method 3 will be updated.
