Method #1: Using Updater App

This method will only work if you have a previous MIUI stable version installed on the device. If you have a developer version, custom ROM, or TWRP installed then look forward to the methods below this one.

Start by downloading the MIUI 9 Stable ROM for Mi 5, 5s, and 5s Plus:

Mi 5: miui_MI5Global_V9.1.1.0.NAAMIEI_c91be5fdc5_7.0.zip

Mi 5s Plus: miui_MI5SPlusGlobal_V9.1.1.0.NBGMIEI_425a5cf0ce_7.0.zip

Connect your Mi device to the PC and transfer the recovery ROM package to the internal storage.

Open the ‘Updater’ app from your device’s homescreen.

When the Updater app opens up, tap on the 3-dot overflow button on the top-right to open the menu.

Then select the ‘Choose update package’ option.

Now, browse through the internal storage and select the recovery ROM zip file (e.g. miui_MI5SGlobal_V9.1.1.0.NAGMIEI_3e22d133b8_7.0.zip).

Once selected press on ‘Ok’ to start the process and install MIUI 9 Stable ROM on Xiaomi Mi 5, 5s, and 5s Plus.

When the installation process is complete, the device will automatically reboot into the update MIUI 9 OS.

Method #2: Using MiFlash Tool

Now, if your Mi 5 device is running on Global/Developer/China ROM, then you can use this method to install the update using MiFlash tool. Before you head to the instructions to install MIUI 9 Stable ROM on Xiaomi Mi 5 devices, make sure to download and install the MiFlash tool on your PC.

Download the Fastboot ROM zip for your device:

Boot your Mi 5 device into Fastboot mode:

Power off your phone completely.

Press and hold the Volume Down + Power button simultaneously to boot into Fastboot mode.

Now, connect your Mi 5 to the PC and launch the MiFlash tool.

Click the ‘refresh’ button in the MiFlash window to make sure that the device is being recognized properly.

Extract the downloaded Fastboot ROM (.tgz) file to an easily accessible location on your PC.

In the MiFlash window, click on the ‘select’ button and select the folder where the files have been extracted. For example, we have extracted our ROM to C:\MIUI\ROM.

The flashing process should be complete in a few minutes. During this time, make sure to leave the PC and the device undisturbed to avoid any problems.

Method #3: Using TWRP Recovery

If your Mi device has TWRP recovery installed on it, you can simply use it to flash the Recovery ROM zip to install MIUI 9 Stable ROM on Xiaomi Mi 5, 5s and 5s Plus.

Now, boot into TWRP recovery:

Press and hold the Volume Up + Power button until you see the Mi logo on the screen.

Then, release the Power button and keep on holding the Volume key until you see TWRP recovery mode.
