Xiaomi Mi 5 firmware: official and custom methods with unlocking the bootloader

Xiaomi Mi 5 (codenamed gemini) may be required to upgrade to the current version of MIUI, install custom firmware such as LineageOS or Pixel Experience, or to restore performance after a failure. Despite the fact that the model was released in 2016, its hardware (Snapdragon 820 processor, 3/4 GB of RAM) is still supported by enthusiasts, and official firmware from Xiaomi is available to version MIUI 12.5 (based on Android 10).

However, the Mi 5 firmware process has nuances: you need to unlock the bootloader, choose the right firmware version (global, Chinese or EEA) and take into account the features of the model - for example, problems with anti-rollback (backward protection on old versions). In this article, we will analyze all the current methods of firmware - from official updates via MIUI Updater to manual installation through Fastboot and TWRP, and also consider typical errors and their solutions.

If your Mi 5 is stuck on the logo, doesn't turn on or is unstable, firmware is often the only solution, but it's important to understand that wrong actions can turn your smartphone into a brick. So before you start, check the version of the current firmware (in Settings → About phone) and the status of the bootloader (unlocked or not).

1. Firmware Preparation: What to Do Before Starting

The first step is data backup. The firmware, especially through Fastboot, erases all user files, including photos, contacts and messages. Use Mi Cloud or third-party tools like Titanium Backup. Note: backup via adb backup may not recover on the new firmware due to changes in the Android API.

Check the bootloader version. The Mi 5 uses anti-rollback protection, which blocks rollbacks on older versions of MIUI. You can find out the current version in Settings → About Phone → MIUI version or via the command:

fastboot getvar anti

Make a backup copy of the data|Check the version. MIUI and anti-rollback|Download the correct firmware (global / Chinese)|Charge your phone at least to 50%|Install drivers ADB/Fastboot PC-only-->

Also prepare the tools:

• 📱 USB-cable (original, without damage).
• 💻 Computer with Windows/Linux (for Fastboot).
• 🔧 Mi Flash Tool (for official firmware) or Platform Tools (for official firmware) ADB/Fastboot).
• 📁 Firmware in.tgz format (for Fastboot) or.zip (for Recovery).

2 Unlock the bootloader on Xiaomi Mi 5

The official firmware through Fastboot requires an unlocked bootloader. Xiaomi allows unlocking, but the process is tied to the Mi Account and takes up to 720 hours (30 days) of waiting.If you've already unlocked the bootloader before, this step can be skipped.

Instructions for unlocking:

1. Link the device to your Mi Account in Settings → Xiaomi Account.
2. Activate USB debugging: Settings → About Phone → MIUI version (click 7 times), then Settings → Additional → For Developers → Debugging over USB.
3. Install Mi Unlock Tool from the official website.
4. Connect your phone in Fastboot mode (click Volume Down + Power) and follow the program instructions.

If you have a "Couldn't unlock" error when you unlock, check:

• 📅 Waiting Date (if you have previously tried to unlock).
• 🔄 Mi Unlock Tool (should be the last version).

3. Ways to Firmware Xiaomi Mi 5

The choice of method depends on the purpose:

• 🔄 Official updates - through MIUI Updater (without unlocking).
• 📥 Manual firmware - via Recovery (requires an unlocked bootloader for custom firmware).
• 🛠️ Recovery – via Fastboot (the most reliable way to crash).

Let us consider each option in detail.

Through MIUI Updater (official update)|Through Recovery (manual installation) ZIP)|Through Fastboot (complete flashing)|Custom firmware (TWRP + LineageOS)-->

Firmware via MIUI Updater (without PC)

The easiest method, but it only works for official updates, which is fine if the phone is turned on and connected to the Internet.

1. Go to Settings → About the phone → System update.
2. Click Update Checker.
3. If the update is available, download and install it.

If the update is not available, try downloading the full firmware package (.zip) from MIUI Downloads and installing it via Select the update file in the same menu.

Firmware through Recovery (manual installation)

This method is suitable for installing official firmware in.zip or custom format (if TWRP is installed).

1. Download the firmware (for example, from here) and rename the file to update.zip.
2. Move the file to the root of the internal memory.
3. Turn off the phone and press Volume Up + Power to enter Recovery.
4. Select Install update.zip to System (for official firmware) or Install (for TWRP).

⚠️ Note: Installation of custom firmware through TWRP It requires the recavery itself to be pre-installed. TWRP 3.7.0. Don’t use older versions – they may not support data encryption!

Firmware via Fastboot (full flashing)

The most reliable way, especially if the phone doesn't turn on, requires an unlocked bootloader and PC.

1. Download Fastboot firmware for gemini from the official website (choose the version of Fastboot).
2. Unpack the archive in a folder with the Mi Flash Tool.
3. Connect your phone in Fastboot mode (clip Volume Down + Power).
4. In the Mi Flash Tool, select the firmware folder and click Refresh → Flash.
5. Wait until the end (the process will take 5-10 minutes).

If the Mi Flash Tool is an error "flash_all_lock.bin", remove this file from the firmware folder – it is designed for blocked downloaders.

💡

If the phone is stuck on the logo after Fastboot, try resetting it via Recovery: Wipe & Reset → Wipe All Data. This often solves the problems with the first run.

4. Install custom firmware (LineageOS, Pixel Experience)

Custom firmware gives the Mi 5 a second life: an updated Android (up to 12-13 versions), no MIUI ads, and better optimization. However, installing them requires an unlocked bootloader and TWRP.

Step-by-step:

1. Install TWRP via Fastboot: fastboot flash recovery twrp-3.7.0-gemini.img fastboot boot twrp-3.7.0-gemini.img
2. Download custom firmware (e.g. LineageOS 18.1) and GApps (if you need Google services).
3. In TWRP, run Wipe → Advanced Wipe and mark Dalvik, Cache, System, Data.
4. Install firmware, then GApps (if needed).
5. Reboot.

1. Charge the battery (plug it into the ROM for 30 minutes).
2. PC Connection – Is the Device Manager Defined Device Device as Qualcomm HS-USB QDLoader 9008 (if yes, firmware is required through the EDL-regime).

• 🛠️ Set up productivity: in Settings → Battery → Select Performance Mode "High Performance" (for games).
• 📸 Install GCam: for Mi 5 suitable modification Arnova8G2 or BSG.
