Xiaomi Redmi Note 8: How to reflash and restore the system

The Xiaomi Redmi Note 8, released in 2019, is still a popular device due to its balance between cost and performance. However, over time, the software stops updating officially, there are system failures or accumulated software errors that cannot be corrected by a conventional reset, and it is in these situations that the owner faces the question of manually reinstalling the operating system, which allows you to return the gadget to a second life or install custom firmware.

The process of flashing Xiaomi Redmi Note 8 requires care and preparation, as incorrect actions can lead to data loss or software failure. Unlike the more simple models, this device is based on the Snapdragon 665 processor and has specific requirements for drivers and connection modes. We will look at all the steps from unlocking the bootloader to installing the global version of the firmware through Mi Flash utilities.

Before you start technical manipulation, you need to be aware of the risks and prepare the workplace.

The success of the operation depends on 90% of the correct preparation of the environment. You will need to download and install specialized drivers ADB and Fastboot, which allow the computer to communicate with the phone in the back mode. Without these components, the system simply will not see the device in the desired state, and the firmware process will not begin.

The next step is to choose the firmware itself. The Redmi Note 8 has a variety of versions: Global (global), China (Chinese) and EEA (European). The global version usually contains all the necessary languages and services of Google, which makes it preferable for most users.

After downloading all files, unpack the firmware archive into the root folder of the disk, for example, C:\rom\, so that the path to the files does not contain Cyrillic characters or spaces, which can cause an error in the operation of the scripts. Check the integrity of the downloaded files, comparing their checksums with those indicated on the developer's website, if such an opportunity is provided.

Unlocking the Bootloader bootloader

Xiaomi’s official policy is to have a closed bootloader, which blocks third-party firmware installation and superuser rights. You need to get permission to unlock to get started. This is not an instantaneous process: you’ll have to wait 7 to 168 hours after you apply in the Mi Unlock Tool app, and ignoring this step will make it impossible to install custom recovery or global firmware on the Chinese version.

The procedure begins with the binding of the Mi Account in the smartphone settings. You need to go to the Settings menu. → The phone. → Version. MIUI and click on the logo several times to activate the developer menu. Then, in the advanced settings, look for Mi Unlock Status and link the device to the acca.--->

Installation of drivers and login to Fastboot mode

Computers running modern versions of Windows (10 and 11) They can automatically install the underlying drivers, but the correct operation of firmware tools often requires manual installation or updating of drivers through the Device Manager (COM and LPT)" or "Other devices" appearing on Android or QHSUSB_BULK with a yellow exclamation mark, so the drivers are installed incorrectly.

For the correct connection, switch the phone to Fastboot mode (Loud Down buttons) + Power, connect the cable to the port. USB 2.0 (preferably behind the system unit), avoiding USB-Hubs and front panels of the case, which can give voltage drawdowns.

Firmware via Mi Flash Tool (Official Method)

Mi Flash Tool is the main tool for installing official firmware in Fastboot mode. This method is the most secure and preferred for returning the device to a factory state or transitioning from the Chinese version to a global one. The program interface may seem minimal, but it contains all the necessary functions to control the process.

Run the program on behalf of the administrator. Press the Select button and point the path to the unpacked firmware folder. It is important to choose the folder where the image file and the script are located. flash_all.bat, After choosing a path, the program will analyze the structure of the files and determine the model of the device.

At the bottom of the window you will see three options for firmware:

• 🧹 clean all: Completely clean all data and partition re-marking (recommended).
• 💾 Save user data: Attempting to save user data (may cause errors when changing region).

Once completed, the phone will automatically restart. The first download can last up to 10-15 minutes, do not panic if the screen stays black for a long time or the logo hangs.

Installation of custom TWRP Recovery

For advanced users who want to gain full control of the system, a customized recovery such as TWRP (Team Win Recovery Project) is required, which allows you to install modified firmware, make full system backups and obtain Root rights.

It is necessary immediately after executing the command in the terminal to pinch the combination of buttons Volume Up + Power before the appearance of the MI logo.

Solving errors and problems in firmware

Flashing can cause various errors that are displayed in the program log, and one of the most common is Error: Flash all except data storage, or connection timeout. USB-Try reconnecting the cable to another port, preferably a cable or a port. USB 2.0 and use another wire.

Another common problem is the Can't find md5 or Miss matching image error, which indicates that the firmware files are damaged when downloaded or unpacked. Check the integrity of the archive and make sure that the path to the folder does not contain Russian letters. Also make sure that the antivirus does not block the work of the firmware scripts.

If the phone is in a deep reboot cycle and does not respond to buttons, you may need to enter EDL (Emergency Download Mode). For the Redmi Note 8, this often requires disassembling the case and closing contacts on the board (test points), since the program input to the EDL on new versions of the bootloader is blocked.
