So, Android 8.1 Oreo with Xiaomi’s official MIUI version 9.5 already available for the Chinese variants of Redmi Note 5 Pro. It is still not available in other countries. Specifically, if we talk about India, recently the developer builds of this ROM is leaked and publicly available for the Redmi Note 5 Pro users. So, now, anyone can install Android 8.1 Oreo-based MIUI 9.5 ROM on their Redmi Note 5 Pro.

The installation process is quite simple. Because you are not going to install any other custom ROM, it is officially made for the Redmi Note 5 Pro. So, let’s dive into the complete process.

#1. Submit Bootloader Unlock Request

To install the Android 8.1 Oreo ROM on your Xiaomi Redmi Note 5 Pro device, the first thing, you have to do is Unlock the Bootloader. For that, you have to send the request to Xiaomi to unlock Bootloader of your device which takes around 3-4 days.

To begin the process head over to the Xiaomi Bootloader Unlock Request site, where you have to sign in using your Mi account. Once you will sign in, you should get the screen like I have attached screenshot below.

Write your name, mobile number and write the actual reason in the last tab to submit the request to get the permission for Bootloader unlock. When Xiaomi will accept your request, it will send the text message to your mobile number. It will say, your permission is granted for the bootloader unlocking.

#2. Unlock Bootloader

To unlock the bootloader, follow the steps.

  • Once you get the permission to unlock your device Bootloader, head over to the Xiaomi website to download the Unlocking Tool.
  • Download it and extract it.
  • Open extracted folder. Inside the folder, you will find the Mi unlocking driver (Mi Unlock app). Open and install that on your computer
  • Shut down your phone manually, and hold Volume down key and Power button to enter Fastboot mode.
  • Connect your phone to PC using the USB cable.
  • Open that Mi Unlock App and sign in with your Mi Account.
  • The Unlock app should automatically detect your device. Once your device detected, hit on Unlock button.
  • That’s it. It will load the progress bar on the screen.

*Some Cases: There are some cases, where the user get an error after the 99% of progress and gets the message, “Current Account is not Bound to this Device.” If you are one of them, that means still, Xiaomi has not internally approved your request. You have to still wait for 4-5 days. Just check daily. It will work.

#3. Install TWRP Recovery
