This is a dead easy way to check Redmi Note 3 bootloader status whether it is locked or unlocked. As you may already know it that all recent Xiaomi devices are shipped with locked bootloader to protect the ROM and the phone from being tampered with changes users don’t know. However, this could be troublesome for many users especially when they want to root their phone. Users cannot flash custom recovery and therefore they also cannot flash SuperSU to gain root access. On top of that, they will not be able to flash MIUI Fastboot ROM and do clean install on it.
Now just in case you need this two cents trick especially when you bought a secondhand phone. Do not, and never, try to flash MIUI Fastboot ROM using MIUI Flashing tool without firstly checking its bootloader status. Otherwise you may end up with a bricked device. A bootloader is a code that executes before the main operating system run.
Now let’s find out how to check its status:
Step 1 – Download and install ADB Driver installer and install it on your computer. However you don’t have to do this step if you have either Mi PC Suite or Mi Flash Tool installed.
Step 2 – Download and extract Minimal ADB and Fastboot package into your computer.
Step 3 – Open up Windows Explorer and go to the location of where you’ve extracted Minimal Fastboot and ADB Files.
Step 4 – Hold down the Shift button on your keyboard and right-click in that location. Choose “Open command window from here”
Step 5 – Turn of your phone completely. Now reboot it into Fastboot mode by pressing Volume Down (-) and Power button until you see the Fastboot logo.
Step 6 – Now connect your phone into your computer using its USB cable.
Step 7 – Execute this command (type it and hit enter on your keyboard):
That will list all connected device which in this case is your phone only. You may need to reinstall ADB USB Driver if your phone is not detected.
Step 8 – Finally, issue this command which is the main command to check bootloader status of your phone :
fastboot oem device-info
Step 10 – You will then see either “Device Unlocked: True” or “Device Unlocked: False“.
This method can be done easily using a Flasher Tool for Redmi Note 3.
Step 1 – Download Flasher Toolkit and install it on your computer. Just follow the tutorial explained in the download page.
Step 2 – Grab your phone and its USB cable. Make sure it is turned on (in ON state).
Step 3 – Connect it to your computer using its cable.
Step 4 – Open up Windows Explorer and go to the location of where you have extracted Flasher Toolkit.
Step 5 – Right-click on “Flasher Toolkit v1-03.bat” file and choose Run as administrator.
Step 6 – From here you can simply choose option number #7.
Step 7 – That’s it. The bootloader status of your phone will be displayed instantly.
My bootloader is locked, how to unlock it? You can apply for official bootloader unlock permission or use this guide to unlock it unofficially.
Thanks God, the bootloader is unlocked – Of course you can then easily flash TWRP, get root, and optionally install custom ROM.
