Xiaomi Mi5 has been around for a long time, but thanks to its high-quality hardware and system optimization, it is still capable of performing most everyday tasks. However, to keep the device running smoothly and open applications correctly, you need to keep the software up to date. Many owners wonder whether it is worth spending time looking for new versions of the firmware, because official support for the model has long been discontinued.
However, enthusiasts and developers continue to release custom builds that breathe a second life into the gadget. System updates are not just about changing numbers in settings, it is about fixing critical security vulnerabilities and improving compatibility with modern software. In this article, we will discuss all the available ways to upgrade the software for Xiaomi Mi5, from standard methods to advanced installation through Fastboot.
Before taking action, it is important to understand the risks. Any interference in the system partition carries the potential threat of data loss or turning the device into a “brick.” The official latest version of MIUI for the Xiaomi Mi5 is MIUI 9 based on Android 8.0 (Oreo), further updates are possible only through custom firmware. Therefore, careful preparation and backup are mandatory steps, ignoring which can lead to irreversible consequences.
Preparing the device for update
Begin with careful preparation, make sure that the battery is at least 60%, or better fully charge the device, interrupting the firmware process due to battery discharge is the most common cause of fatal failures, after which recovery takes hours or requires soldering.
It's also critical to make a full backup of all your data. Use the built-in Mi Cloud or third-party services like Google Drive. Remember to copy your contacts, photos, instant messengers and documents to an external medium or computer. After flashing, your internal memory is often completely cleared.
☑️ Preparation for firmware Mi5
Check the memory space. It takes several gigabytes of free space to download and unpack the firmware archive. If the memory is full, the system may fail to start the upgrade process or fail to do so. Delete unnecessary applications or transfer media files to the memory card if the model supports this format, although the Mi5 lacks a microSD slot.
Official Update via OTA
The easiest and safest way is to use the built-in OTA (Over-The-Air) mechanism, which allows the system to independently check for new versions and download them, but as mentioned, official servers may no longer offer updates to this model, but it is worth checking first.
To do this, go to the settings menu and select About Phone. In the window that opens, click on the MIUI version icon. The system will contact the server and check. If a new version is found, a download button will appear.
- 📱 Press the Download button and wait for the process to end.
- 🔄 After booting, the system will prompt you to restart for installation.
- 📂 The firmware file will be saved in memory, which is useful when re-installation.
If the system says no updates, it means you are on the last version available for your region, in which case the automatic path is closed, and you will have to use manual methods of installing archives.
Manual installation via Recovery
When OTA doesn't work, Recovery mode comes to the rescue, which requires you to pre-download the firmware archive with the.zip extension. It's important to choose a file labeled "Recovery" rather than "Fastboot" because they have different structures.
Copy the downloaded file to the root of the device's internal memory. Then go to the update menu (the same as the OTA check) and click on the three dots in the upper right corner. Select the firmware file and specify the path to the downloaded archive.
⚠️ Note: If the system gives an error "Can't verify update", it means that you are trying to roll back to an older version or change the region (from Global to China or vice versa.
Once the selection is confirmed, the verification and installation process will begin, the screen will go out, and the Mi logo will appear with a progress lane. Don't touch the device at this point. The entire process takes 5 to 15 minutes depending on the memory speed.
What if Recovery doesn’t see the file?
Firmware through Fastboot mode
For advanced users, the Fastboot firmware method is available, which allows you to install the system cleanly, fixing file system errors and removing system debris, and this requires a Windows computer with ADB/Fastboot drivers installed.
Download the firmware archive with the.tgz extension and unpack it on your computer. In the unpacked file folder, find the executable file. flash_all.bat (Connect the smartphone to the PC by holding the volume down button.
fastboot devicesType this command in the command line. If the computer sees the device, it will give you a serial number. If not, install the Xiaomi USB Driver drivers. Once you successfully connect, start the firmware script. The whole process will take a few minutes, at the end the device will reboot automatically.
| Parameter | Recovery ZIP | Fastboot TGZ |
|---|---|---|
| Type of installation | Update on top | Complete cleaning |
| Data retention | Yeah (usually) | No (all removed) |
| Difficulty | Low. | Tall. |
| The need for a PC | No. | Yes. |
Installation of custom firmware
With official support for the Xiaomi Mi5 (codename gemini) complete, the only way to get a fresh Android (10, 11 and above) is to install custom firmware. Popular options include LineageOS, Pixel Experience and Xiaomi.eu (port).
To install third-party software, you need to unlock the bootloader. This is an official procedure from Xiaomi, requiring application and waiting from 3 to 7 days, after unlocking, a custom recavator, such as TWRP, is installed.
- 🔓 Unlock the bootloader through the Mi Unlock Tool utility.
- 💾 Install. TWRP Recovery via Fastboot.
- 📥 Download the custom firmware zip file and install it through TWRP.
⚠️ Warning: Unlocking the bootloader automatically resets all data on the device and may result in a loss of warranty (though for the first time ever, the bootloader will be able to reset the data on the device). Mi5 Some banking applications may also stop working without further manipulation (Magisk).
💡
Before installing custom firmware, be sure to make a backup section EFS/NVRAM through TWRP. That'll keep yours. IMEI and MAC-Addresses that will make it impossible to connect to the cellular network.
Solving problems and mistakes
There can be unforeseen complications in the process of updating, and one of the common problems is the bootloop, where the phone is endlessly rebooted on the logo, most often solved by a full reset (Wipe Data) via Recovery.
If your computer doesn’t see your phone in Fastboot mode, try replacing it. USB-cable or switch port on the motherboard (for PC) USB-Hubs often cause an unstable connection when firmware.
Another mistake is the region mismatch: you can't just go from the Chinese version to the global version without unlocking the bootloader and completely cleaning it up, and trying to do that with standard methods will lead to a verification error.
💡
The main problem when updating old devices is the incompatibility of new versions of Android with an outdated modem driver, which can lead to poor network reception.
