Here's how to install MIUI 12 update on Redmi Note 9S right away

There are several Xiaomi devices that are yet to bag the MIUI 12 update and among them, the Redmi Note 9S, also known as Xiaomi Redmi Note 9 Pro in India.

While the wait is still on for the Redmi Note 9S MIUI 12 update, a Mi Community moderator is suggesting users to go for the Redmi Note 9 Pro MIUI 12 India ROM.

For now, there’s no ETA. You may unlock the bootloader and flash the Indian Fastboot ROM as suggested above, else wait for the Global release.

There are two ways to manually install a MIUI ROM on a Xiaomi device. So, let’s see how you can install the MIUI 12 update on your Redmi Note 9S.

Unlocking the Bootloader

This is the most important part as it is not possible to manually install or flash a ROM without unlocking the device bootloader. Here’s how to go about it:

1. Download and extract the Mi Unlock Tool on your PC.
2. Enable Developer Options on your Redmi Note 9S by heading over to the About Phone section in Settings and tapping seven times on MIUI version.
3. Now, head over to the Developer Options under Additional Settings and enable USB Debugging and OEM Unlocking.
4. Select the Mi Unlock status option found under Developer Options itself.
5. Tap on Add account and device to link your Mi account.

NOTE: If you are getting the error 86012 then you should wait for a week before trying again as multiple attempts might lead to temporary blocking of your account.

Also, if you are facing the “Connect to the network & try again” error then logout from your Mi account on the device.

Now, directly sign in from the Mi Unlock status page using the Add account and device option and the error should get fixed.

6. You will now get the “Added successfully. Mi account is associated with the device now” message.
7. Reboot the device in fastboot mode by pressing and holding the Power and Volume down buttons simultaneously.
8. Once in the fastboot mode, connect your Redmi Note 9S to the PC through a USB cable and launch the Mi Unlock Tool with admin privileges.

9. Click on Agree and login with your Mi Account ID. When you see the Phone Connected status, click on the Unlock button.

NOTE: If you get the “Current account is not bound to this device” error then repeat Step 5 and try to bind the account again. Also, you’ll have to wait till the given time in case you get the “Couldn’t unlock” error.

10. After the specified time, the Phone Connected status page should show the “Unlock will erase user data” message which means that the device bootloader can be unlocked now.
11. Click on the Unlock button to unlock your Redmi Note 9S.

Installing MIUI 12

MIUI ROM can be installed on a Xiaomi device either through the Mi Flash Tool (fastboot method) or Updater app (Recovery method).
