Recovering a smartphone after a critical failure or installing a fresh version of the operating system often requires the use of specialized software. For owners of Xiaomi devices, the de facto standard is the MiFlash utility, which allows you to perform deep flashing through the Fastboot mode. The Redmi 5 model, despite its age, remains popular, and knowing the process of flashing it can save the device from becoming a “brick”.
This process is fast and requires careful attention to detail, as any error in the connection or file selection stage can lead to incorrect operation of communication modules or complete locking of the bootloader. Unlike the update “over the air”, the method through the computer gives full control over the memory partitions and allows you to roll back to an earlier version of Android if the new one works unstable.
Before you start any manipulation, you need to be aware that you are taking responsibility for the software of the device. Although the risk is minimal if you follow the instructions, there is always a theoretical possibility of data loss or maintenance, and we will discuss in detail each step, from tool preparation to the final launch of the system.
Preparation of the workplace and necessary files
The success of the operation depends on the quality of preparation. You will need a personal computer or laptop running the Windows operating system (versions 7, 8, 10 or 11), as the MiFlash utility is not officially supported on macOS or Linux without the use of emulators. It also needs a proper one. USB-cable, preferably original or certified, capable of transmitting data, not just charging the battery.
The key element is the firmware itself. 5 (codename rosie - you need to download Fastboot ROM, The file will have the.tgz extension, and it's usually about the size of a file. 2–3 Gigabyte. After downloading, the archive must be unpacked into the root of the disk so that the path to the folder is short and does not contain Cyrillic characters, for example: C:\xiaomi\rosie_global.
⚠️ Note: Use firmware from other models (e.g. Redmi 5 Plus or Redmi) 5A) Always double-check the device code name in settings or on the box before downloading files.
Also at this stage, make sure that there is enough free space on the disk where you unpacked the firmware. The process of unpacking and subsequent operation of the program may require a temporary buffer. Do not place firmware files in long-path system folders such as Desktop or Downloads, if the user name is written in Russian - this is a common cause of path recognition errors.
💡
Use it. USB-port built directly into the computer motherboard (back of the system unit), rather than the front panel ports or USB-hubs to avoid power and data transmission problems.
Installation of ADB and Fastboot drivers
The computer must "see" the smartphone in a special diagnostic mode, which requires Qualcomm or Xiaomi USB Driver drivers. Without them properly installed, the Device Manager will display unknown hardware, and the flasher program simply will not be able to initiate a connection. Most drivers are bundled with the MiFlash utility archive, but they can be installed separately.
The process of installing drivers sometimes does not automatically, requiring manual selection of the device from the list. If when connecting the phone in Fastboot mode, a section "Android Phone" with a yellow exclamation mark appears in the Device Manager, then the driver is incorrect. In this case, you need to update the driver manually, indicating the path to the driver folder inside the firmware directory.
- 📱 Download the current driver package from an official resource or trusted source.
- 💻 Run the installer on behalf of the administrator by right-clicking on the executable file.
- 🔌 Connect the smartphone turned off by pressing the volume down button to check for a new device.
- 🔍 Device Manager should have a device called Android Bootloader Interface or Qualcomm HS-USB QDLoader 9008.
Note that in Windows 10 and 11, the security system can block the installation of drivers without a digital signature. If the installation is interrupted by an error, you may need to temporarily disable the verification of driver signatures through the boot parameters of the system.
Downloading the smartphone in Fastboot mode
Fastboot mode is a low-level debugging protocol built into the Android bootloader. It's in this mode that the phone takes commands to write data into memory, bypassing the main operating system. To go into this mode on the Redmi 5 off, you need to press the volume button and, holding it, connect the USB cable to the computer.
The screen will show a characteristic image of a hare in an orange cap fixing an android, or a FASTBOOT sign on a black background, which signals that the phone is ready to take commands. If the screen remains black, the battery may be dead, and the device should be held on charge for 15-20 minutes before retrying.
⚠️ Note: If the phone goes into a cyclic reboot (bootloop) and is not included in the Fastboot by holding the buttons, it may be necessary to disassemble the case and short-term closure of test points on the board to enter the mode EDL, But that's the level of the service center.
It's important not to confuse Fastboot with Recovery. In Recovery, the menu is called by pressing the power and volume button up, and it looks like a text menu. To work with MiFlash, we need the bootloader mode with the image of the hare. Being in the right mode is a critical success factor.
☑️ Firmware readiness
Setup of the MiFlash Tool program
Once you successfully connect your device, run the XiaoMiFlash.exe executable. The program interface may seem ascetic, but it contains all the necessary tools. First, click the Refresh button in the upper right corner. If the drivers are installed correctly, your Redmi 5 serial number will appear in the list.
Then you click select and point the path to the folder with the unpacked firmware. The program automatically scans the folder and, if the file structure is correct, the path will be confirmed. Pay special attention to the firmware selection unit at the bottom of the window, as this determines the fate of your data.
| Firmware mode | Description of action | Data retention | Recommendation |
|---|---|---|---|
| clean all | Complete cleaning and installation | No (all removed) | Recommended for stability |
| save user data | Updating with preservation | Yeah (photos, contacts) | Only when updating the version |
| clean all + lock | Cleaning and locking the loader | No (all removed) | Only for global versions |
The clean all option is the safest and most recommended option, as it eliminates conflicts between the files of the old and new system. The clean all + lock option returns the bootloader to the closed state, which is necessary for banking applications and Android Pay (Google Pay), but you can use it only when you run the regional version on the corresponding region.

Firmware process and status tracking
When all settings are set, press flash. You start a data-recording process that takes 200 to 600 seconds on average. You'll see progress messages in the program log: send 'boot', send 'system', etc. At this point, you can't turn off the cable or interrupt your computer.
A smartphone can vibrate several times or even briefly extinguish the screen — this is normal behavior, indicating that partitions are overwritten. If the process is stuck in one step for more than 5-10 minutes, there is likely an error, but it is not necessary to rush to turn off the device, sometimes the program just waits for a response from the port.
Successful completion of the operation will be marked by the flash done message in the status column and a green progress bar indicator, while the phone can independently restart or remain hanging on the Mi logo, which is also the norm for the first run after complete cleaning.
💡
Interrupting the firmware process during the recording phase of the system or boot partition may make it impossible to turn on the phone, requiring recovery through EDL mode and paid MiAuth accounts.
First start and eliminate possible errors
Once the procedure is complete, the phone can boot longer than usual, up to 10-15 minutes, which is the process of optimizing applications and setting up a new file system. If the device is stuck on the logo, try forcibly restarting it by holding the power button for 10-15 seconds.
There may be situations where the firmware has been successful but the mobile network or Wi-Fi is not working. This may indicate a mismatch between the firmware region and the regional version of the device, or damage to the persist partition. In such cases, it may be necessary to restore the IMEI backup or reflash with another cleaning method.
- 🔄 If your phone goes into cyclic reboot, try reflashing with the clean all option.
- 🔌 Check integrity USB-try another port if the device is lost during the process.
- 💾 Make sure that antivirus or firewall does not block MiFlash.
Remember that unlocking the bootloader (if you have changed region from China to Global) is a prerequisite for changing the firmware type. If the bootloader is blocked, the program will give an error when trying to record the image, in which case you must first go through the official unlock procedure through the Mi Unlock site.
