You dont need to apply for official unlocking and wait for a month or more to get the sms confirmation from xiaomi to officially unlock the bootloader, the problem with the official method is many users have reported that they did not receive the confirmation sms from xiaomi, even if they receive the confirmation sms the unlocking process stucks at some percentage and fails to unlock the bootloader.

After completing all the steps successfully, reboot the phone into the system normally and complete the initial setup without Sim card, the first boot may take a little more time to boot into OS, In case if the phone stuck in boot screen for very long(10+ mins), go to troubleshoot section at the bottom and start over the steps. Otherwise you are good to go.

Connect device to Pc after initial setup completes, now copy the "Root Checker.apk" file to your phone and install it, open the root checker app and click on verify root, you will be prompted by Supersu for root permission, allow it, your root access will be verified. Voila, you have successfully rooted, flashed twrp and installed supersu on your Redmi Note 3 with latest rom installed.

That's it. Now you are ready to rock.

KNOWN ISSUES:

No issues found so far, in case if you find any issues after successfully unlocking using the above method, kindly let me know.

After successfully unlocking your bootloader, incase if you update your rom via official updates, your will lose root access and twrp custom recovery and may end up with locked bootloader again, if you face this situation by some reason, you may start over and follow this guide from step 1 to revert back to unlocked bootloader. Do not update the rom and turn off automatic updates in settings as a precautionary measure.

Troubleshoot:

If your device gets bricked or Stuck in Boot logo, try this,

Reboot your phone into edl mode by following below step.

If you are stuck on bootscreen, you may not be able to enter into edl mode using the normal method above because of bootloop or Stuck in Boot logo, in that case try this method to enter into edl mode from fastboot, download "fastboot_edl.zip" file from the link I provided above, extract the zip file and open the extracted folder, connect the phone to your Pc in fastboot mode(vol down + power), double click and run this file "edl.cmd", the phone will automatically enter into edl mode if the phone's drivers and adb drivers are installed properly.​

Now follow step 6 and follow on from this step.​

If QHUSB_BULK drivers are not properly installed while the phone in edl mode,

If QHUSB_BULK drivers are not installed while the phone in edl mode, your device may not be visible in MiFlash tool(ex:COM10) even after you click refresh button, in this case open the device manager in your Pc, the phone will be visible as QHUSB_BULK with some alert sign, right click on it and select Update driver software. Then click browse my computer and browse to the location of the driver files in path "C:\Program Files\Xiaomi\MiPhone\Qualcomm\Driver" and proceed and when prompted to Install this Driver Software anyway, allow it and complete the driver installation. Now open MiFash tool and click refresh button your device will be detected in MiFash tool, now you can flash the fastboot rom by following the steps above.​
