Update Android to Xiaomi Mi Max 2: official and alternative ways

Xiaomi Mi Max 2 is the iconic 2017 phablet with a 6.44-inch screen and 5,300 mAh battery that is still in use by many users. However, with the release of new versions of Android and MIUI, owners face the problem of how to update the system on an outdated device? Official support from Xiaomi has long been discontinued, but this does not mean that your smartphone is doomed to MIUI 9 or Android 7.1 Nougat forever.

In this guide, we will discuss all the current ways to update the Mi Max. 2 (Oxygen and Hydrogen models, including official OTA-packages, manual installation via Recovery and Fastboot, and alternative firmware based on Android 10/11. Particular attention will be paid to unlocking the bootloader - a key step for installing custom firmware, without which most methods simply will not work.

We warn you that the process of updating on outdated devices is fraught with risks. Wrong actions can lead to a “brick” (complete failure) of a smartphone. If you are not sure about yourself, you should consult a specialist or stay on the latest stable official version.

1. Check the current version of the software and compatibility

Before you start updating, you need to accurately determine:

• 📱 The Mi Max 2 came in two versions: oxygen (global) and hydrogen (Chinese). → The phone. → Model or by the inscription on the box.
• 🔢 Current version MIUI/Android — This information is in the same section about the phone, MIUI 9.6.3.0 | Android 7.1.1.
• 🔓 bootloader status - it is locked or unlocked. You can check this with the command fastboot oem device-info (more in the section about unlocking).

The choice of firmware depends on the model:

• 🌍 Oxygen – supports global (Global) and European (EEA) build-up MIUI.
• 🇨🇳 Hydrogen – works only with Chinese firmware, but they can be converted into global.

💡

If there is no Model in About Phone, enter the code ##4636## in the phone app and select Phone Information.

Also check the battery status. It can take up to 30-40 minutes to update, and if the battery runs out in the process, the device will turn into a brick. Charge the smartphone to at least 60% or connect to the charge with the original cable.

2. Official update via OTA (if available)

The easiest and safest way is to upgrade by air" (OTA). But for the Mi Max 2 formal OTA-The packages stopped coming out after MIUI 11 (Android-based 7.1/8.1). However, sometimes Xiaomi releases security patches or minor updates.

2. Click on the three dots in the upper right corner and select Update (if you don’t have one, your version of MIUI doesn’t support it).
3. If you find an update, download it (preferably via Wi-Fi) and install it.

If the system says, "No updates found" or "Your version is current," it means that there will be no official updates for your model, and then you will have to use alternative methods.

Manual update via Recovery (for official firmware)

If OTA doesn't work, but you want to stay on the official firmware, you can manually install the update via Recovery.
