The key factor here is an unlocked bootloader, without which installing custom builds is impossible. If you are willing to take the time to study the nuances, you can significantly extend the life of your device.
Preparing the device and workplace

Make sure the battery charge is Xiaomi is at least 60% so that the process is not interrupted due to a sudden power outage. You will also need a high-quality USB cable that can transfer data, not just charge the device. A defective cable often causes a breakdown in the connection between the computer and the phone at the most crucial moment.
- 🔋 Charge your device to full level or leave it on charge during the process.
- 💾 Make a complete backup of all important files to your computer or cloud.
- 🔌 Use an original cable or a high-quality analogue with data transfer support.
You need to install the correct drivers on your computer to work with the firmware tools. Without correctly installed drivers, the Fastboot or ADB utility will not be able to recognize your Redmi Note 5.
⚠️ Attention: Deleting data when flashing firmware via Fastboot is irreversible. If you don't back up your photos, contacts, and messages in advance, it will be nearly impossible to restore them.
Unlocking the bootloader
The Bootloader is locked by default by the manufacturer to protect against unauthorized intervention. To install a custom kernel or third-party firmware, you must obtain rights to modify system partitions.
The procedure requires account authorization Mi Account and linking it to the device through the developer menu. After submitting an unlock application, you will have to wait from 3 to 7 days, depending on the current account status and user region.
- 🔓 Enable the “Unlock Bootloader” mode in the developer settings.
- ⏳ Wait until the waiting period expires after submitting your application.
- 🖥️ Use the official Mi Unlock Tool on PC for final unlocking.
After successful unlocking, when you turn on the phone, you will see a corresponding warning. This is normal and indicates that the system's security has been compromised. Don't be alarmed by this message as it will appear on every device with an unlocked bootloader.

Official firmware via Mi Flash Tool
The most reliable way to restore the system is to use the official utility from the manufacturer. This method allows you to completely wipe your device and install a clean version of MIUI suitable for your region.
Download firmware only from trusted sources, such as the official MIUI website or specialized forums. It is important to choose the version Fastboot (files with the .tgz extension), and not Recovery, since Mi Flash Tool does not work with archives for recovery through the menu.
The process of unpacking the archive with firmware requires attention. After extracting the files, you will see a folder with the name of the model and many files with the .img extension. This is the directory that needs to be specified in the program.
☑️ Preparation for Mi Flash firmware
Installing custom TWRP recovery
For advanced users who want to gain maximum control over their device, installing a custom recovery is a mandatory step. TWRP (Team Win Recovery Project) provides advanced capabilities for backing up and installing modified assemblies.
The installation process requires finding a recovery image that is compatible with your board revision Redmi Note 5 (Japanese version is different from global version). An error in selecting a file will result in system inoperability.
After installing TWRP, you will be able to create full images of partitions (Nandroid backup), which allows you to roll back the system to any point in the event of unsuccessful firmware. It is the most powerful tool in an enthusiast's arsenal.
⚠️ Warning: Installing an inappropriate TWRP image may result in loss of data encryption or inability to boot into stock MIUI without a full flashing.
Secrets of working with TWRP
In TWRP, you can not only flash ZIP files, but also mount partitions like a flash drive, change the slot size, and even transfer the system to an SD card if it supports the A2 standard.
Selecting and installing custom firmware
If the standard MIUI seems heavy or slow to you, custom builds based on Android come to the rescue. Popular projects such as Pixel Experience or LineageOS turn Xiaomi into a pure Android smartphone without unnecessary software.
Before installing any custom build, you must double format the data (Format Data) to remove encryption and avoid errors when writing files. This action will destroy all internal data, so make sure you have a backup.
- 🌐 Download the latest stable firmware from the official XDA Developers forum.
- 📦 Transfer the firmware file to the device memory or to a memory card.
- 🔄 In the TWRP menu, select “Install” and specify the path to the archive with the firmware.
After successful installation, be sure to clear the cache (Wipe Cache/Dalvik) to avoid conflicts between old and new system files. The reboot may take longer than usual as the system optimizes applications on the first launch.
Before downloading custom firmware for the first time, disable automatic reboot in the TWRP settings so that you have time to see possible console errors if they arise.
Version and model compatibility table
Understanding the differences between device versions is critical to successful flashing. Smartphone Redmi Note 5 has several revisions, and the firmware files for them are not interchangeable.
| Model | Codename | Features | Compatibility |
|---|---|---|---|
| Redmi Note 5 Pro | whyred | Snapdragon 636 processor | Pro version only |
| Redmi Note 5 (Global) | kenzo | Snapdragon 625 processor | Traveler (Note 5) |
| Redmi Note 5 (China) | rosy | Snapdragon 625 processor | Only for Chinese version |
| Redmi Note 5A | ross | Snapdragon 435 processor | Not suitable for Note 5 Pro |
Using the firmware for the model kenzo on the device whyred is guaranteed to lead to a “brick” of the smartphone. Always check the codename in the developer settings before uploading any files.
Troubleshooting common errors
Even if you follow all the instructions, problems may arise. The most common mistake is getting stuck on the Xiaomi logo after flashing the firmware. This often happens due to incompatibility between the Recovery version and the installed firmware.
If the device is not detected by the computer in Fastboot mode, try changing the USB port to another, preferably USB 2.0. Sometimes drivers conflict with new standard ports, especially on older motherboards.
Errors during installation via Mi Flash Tool are often related to file permissions. Run the utility as an administrator and make sure that the path to the firmware files does not contain Cyrillic or spaces.
The most common cause of a “brick” is an attempt to flash the global version on a Chinese device without first changing the region via ADB or using specialized tools.
⚠️ Attention: If the phone does not turn on and does not respond to buttons, you will need EDL (Emergency Download Mode). Entering this mode often requires a special adapter (EDL Box) or opening the case to complete the contacts on the board.
