How to Fix Bricked Mi Max on MIUI 8 with Locked Bootloader

miui 8 mi max flashing

For whatever the reason is, there is always a possibility that your Xiaomi device becomes bricked or may be in the bootloop state making it unusable unless your bring it to life again. There might be many ways to fix it but the one and the finest solution is by reinstalling its OS which in this case is the MIUI ROM. In many cases, reflashing MIUI ROM on your phone can be the first possible solution when your phone is bricked (as long as not a hard bricked). Softbrick is a state when your Android device is damaged in terms of its software and not hardware.

This article will show you a step by step guide on how to fix Mi Max either 32GB (Hydrogen) or 64GB/128GB (Helium) variant by reflashing MIUI 8. This method works on both locked and unlocked bootloader.

Usually we always suggest you to firstly take backup before flashing but you can’t do that in the case of a bricked device. Hence, we can only pray that you created a backup before your device got bricked. You should take regular backup of your phone whenever possible as a precaution if such situation happens. Backing up all important data and files from your phone is really a good practice.

How to Flash

Step 1 – Disable Windows Drivers Signature Enforcement on your computer. How to do it? Simply follow these sequence. You can do that by pressing Windows button + i on keyboard to reveal the Settings page. From there you can choose Update & Security >> Recovery >> Advanced startup >> Restart now. Wait a moment for your computer to restart.

Step 4 – Now you have to firstly boot your phone into Emergency Download Mode (EDL Mode). You can read and follow my previous guide : How to put Mi Max into EDL mode. Alternatively, you can also try this one :

  1. Turn off your phone completely.

  4. Now grab your phone.
  5. Press and hold Volume Up (+) as well as Volume Down (-) buttons all together and then plugin another end of the USB cable to your phone while the buttons are still pressed. Alternatively if that also didn’t work: Press and hold Volume Up + Volume Down + Power buttons all together, connect it to USB cable (which still connected to PC), and then release the Power button at the first vibration. Wait for the device to vibrate for the second time and release both Volume buttons.

EDL Mode Alternative #2:

    This would have been the perfect solution for my situation, but every time I try to start flashing, I get “Error: Can not read from port” in MiFlash after a few seconds. Any advice, ideas, maybe even a solution? 🙁
