    i have a redmi 3, and still waiting for my unlock request to be approved by Xiaomi, I NEED TO ROOT my device, is this tutorial something that i can do to root my device without unlocking bootloader ?

    • farieznur

      No, you will still need to have account granted to unlock your phone’s bootloader

  • Nathaniel

    will this rom support fingerprint

    • farieznur

      I believe so. Because it doesn’t alter many settings of default image

  • Nathaniel

    pls tell fast

  • Alwyn Zhang

    Hi, I’m kind of new to rooting and stuff. After i’ve repacked and gotten my new boot.img file, what next? how do I flash it over to the phone?

    • farieznur

      use the newly created boot img (place it inside image folder of extracted fastboot ROM) then use MiFlash to flash the ROM.

      • Alwyn Zhang

        thanks! Does it have to be a fastboot ROM? Can it be a global stable rom? I’m using the Redmi Note 3 Snapdragon 650

        • farieznur

          Fastboot rom for either Global Stable or China Stable but not Recovery ROM

  • Den Goh

    Dear Sir,

    I want to request you to please give me a step by step instructions to repak boot image and install it via mi flash. The problem is that I have downloaded the fast boot rom from the above given link for my redmi note 3 which is currently on MIUI 7 Global 6.5.19 Beta .. and got the bootloader unlocked officially.. when I extracted the fast boot rom zip I did not get any folder named “image” in it .. just get to see a disk image with some other few files and two three folders. I repack that disc image and .. when tried to flash it.. via mi flash.. it said that…the repacked rom is missing some 0000*0000 file..

    • farieznur

      Fastboot rom always has .tgz extension. The one you downloaded (.zip) is recovery ROM. You have just used the wrong ROM 🙂 Try it again
