How to update Xiaomi Redmi Note 6 Pro: Full Guide

Owners of the popular Xiaomi Redmi Note 6 Pro smartphone often wonder about the relevance of the software, because the device was released several years ago. Despite the age of the model, periodic installation of security patches and optimizations can significantly extend the life of the gadget. The process of upgrading the system does not always go smoothly, so it is important to understand the differences between automatic and manual methods.

There are several proven ways to install the new version of MIUI, each with its own features. Automatically upgrade through the settings menu is the easiest way, but it is not always available if the phone is sourced from China or unlocked by the bootloader. In such cases, manual methods come to the rescue, requiring a deeper dive into technical aspects.

Before you start taking action, you need to evaluate the current state of your Redmi Note 6 Pro. Check the device model, firmware region and battery level, as these parameters critically affect the success of the procedure. Ignoring basic requirements can lead to malfunctions in the operating system.

Preparation of the device for the update procedure

Any interference with system files requires prior preparation to minimize the risk of data loss. The first step should always be to create a full backup of important information, including contacts, photos and messages, and you can use built-in MIUI tools or third-party cloud services to do this.

Make sure that the battery is at least 60% as the process of writing new data is energy intensive, and check for free space in the internal storage, as the installation file can weigh between 1.5 and 2.5 GB.

It is important to know the exact modification of your smartphone, as the firmware for the global version will not work for the Chinese version and vice versa. You can find this information in the Settings → About the phone section, where the full version of the software and the type of device are indicated.

⚠️ Warning: Attempting to install firmware from another model or region without first unlocking the bootloader is guaranteed to lock the device.

Automatic updates via OTA

The safest and easiest way to get a new version of the system is to use the built-in OTA (Over-The-Air) mechanism. To do this, go to the settings menu and select About phone, then click on the logo of the version of MIUI. The system will contact the server itself and check for current packages.

If you find an update, you will see a download button, and then you will click on it and you will start downloading the archive, and depending on the speed of the Internet connection, this process can take anywhere from 10 minutes to an hour, and after you download it, the system will prompt you to restart and start installing it.

💡

Use a stable Wi-Fi connection to download OTA-updates to avoid communication breakdown and damage to system files.

In some cases, automatic search may not yield results, although a new version already exists, often due to the phased deployment of firmware by Xiaomi servers, in which case you can try to change the region in the settings or use a manual method.

It is worth noting that OTA-updates usually come in small portions to fix specific bugs. Major Android updates on older devices like the Redmi Note 6 Pro via OTA They may not be available if support for the model is officially discontinued.

Manual installation via Recovery Mode

If the automatic method did not work, you can use manual installation through recovery mode. To do this, you need to download the Recovery firmware archive (usually with the.zip extension) from the official website or proven resources.

To enter Recovery mode, turn off your smartphone completely, then press the up volume and power buttons simultaneously. Once the Mi logo appears, release power, but continue to keep the volume until the menu appears. Choose the language (usually English or Chinese) and go to Install update.zip or the like.

The system will check the digital signature of the file before installation, and if the signature does not match the region of the device or the version older than the current one, you will see a validation error, in which case you will need to clean the data or use Mi Flash.

⚠️ Note: Manual installation via Recovery often requires Wipe Data formatting, which will result in the complete removal of all files from the phone.

Once installed successfully, the device will restart and the initial setup will begin, and the first run may take longer than usual, as the applications and cache are optimized.

Firmware via Mi Flash and Fastboot

The most radical and complete method is to use the Mi Flash utility on your computer, which allows you to install a clean version of the system, ignoring the limitations of regional locks, but requires an unlocked bootloader.

To get started, download and install the ADB and Fastboot drivers, as well as the Mi Flash Tool program itself on your PC. Download the Fastboot firmware archive (.tgz extension), unpack it into the root of the C disk so that the path does not contain Cyrillic or spaces.

adb reboot bootloader

Transfer the smartphone to Fastboot mode by clamping the volume reduction button when connected USB-In Mi Flash, select the path to the unpacked firmware and press the Refresh button to let the computer see the device. Select Clear all mode and press Flash.

The firmware process will take 200 to 600 seconds. Once completed, the phone will automatically restart. If the bootloader status is not changed to Unlocked, the process will end in error.

💡

Using Mi Flash is the only way to change the firmware region (e.g. from China to Global), but it requires unlocking the bootloader.

Solving common mistakes

During the upgrade process, Redmi Note 6 Pro users may encounter various errors such as "Can't verify update" or endless reboot. Often the problem lies in a corrupted firmware file, so it is recommended to recheck the checksum of the downloaded archive.

Another common cause of failure is version incompatibility: You can’t roll back to an older version of Android without completely cleaning up the data and special manipulations with anti-rollback, and an error can occur when there is not enough free memory.

If the device is stuck in a bootloop, try entering Recovery mode and resetting the settings (Wipe Data/Factory Reset), in the worst case, you will need to flash through the Fastboot with a full partition cleanup.

If you have an error "Error 7" when installing through Recovery, most likely, the version of the bootloader does not meet the requirements of the new firmware, in which case only the transition to an official service center or the use of Mi Flash will help.
