Xiaomi bootloader unlock code: official and alternative ways to obtain

Unlocking the bootloader on Xiaomi smartphones is a must for custom firmware installation, root rights or device recovery after software failures. However, the company has a strict control over this process: it is impossible to unlock the bootloader without official permission. In 2026, the rules have changed, even for older models, you need to be checked through Mi Account, and the waiting time for code can stretch for weeks.

Many users face problems: the system refuses to issue code without explaining the reasons, the waiting counter is reset, or the device is not recognized in the Mi Unlock Tool. In this article, we will analyze all the current ways to obtain an unlock code, from official request to workarounds for power users, and find out which Xiaomi models (including Redmi and POCO) fall under the new restrictions, and how to speed up the process.

⚠️ Important: Unlocking the bootloader will void Xiaomi's warranty and may result in data loss.Backup is a must before any manipulation.

Why Xiaomi is blocking the bootloader and why unlock it

Xiaomi has been blocking the bootloader on all its devices since 2016 for two key reasons:

• 🔒 Security: Protection against the installation of malware or uncertified firmware that may compromise user data.
• 📱 Ecosystem Control: Preventing custom firmware that bypasses Xiaomi’s built-in services (e.g. advertising in the company’s homepage) MIUI).
• 🛡️ Warranty obligations: Unlocking automatically removes the device from warranty, which reduces the load on service centers.

However, unlocking the bootloader opens up wide possibilities for the user:

• 🔄 Install custom firmware (e.g. LineageOS, Pixel Experience) to update outdated models.
• 🛠️ Getting root rights for deep system setup or removing embedded software.
• 🔧 Brick recovery after failed firmware through Fastboot or EDL.
• 📡 Overclocking the processor or modifying the core to improve performance.

Since 2023, Xiaomi has tightened its policy: even to unlock older models (such as the Redmi Note 5 or Mi 8) requires a binding to a Mi Account with a confirmed phone number.

Receiving code through Mi Unlock Tool

The only legal method of unlocking is to use Xiaomi’s Mi Unlock Tool, a process that involves several steps, each of which is important to a successful outcome.

Step 1: Preparation of the device

Before requesting a code, it is necessary to:

1. Attach Mi Account to your device in settings (Settings → Xiaomi Account). Make sure your account is confirmed by phone and email.
2. Enable USB debugging (Settings → About Phone → MIUI Version (click 7 times) → Additional settings → For developers → Debugging over USB).
3. Attach the device to your account in Settings → Additional settings → For developers → Unlock status Mi.
4. Install the latest version of MIUI (update via Settings → System Update).

Step 2: Installation of Mi Unlock Tool

Download the official utility from Xiaomi's website (link: en.miui.com/unlock).

• 🖥️ Use Windows. 10/11 (On macOS or Linux, the utility does not work).
• 🔌 Connect your phone to your PC through the original USB-cables (cheap cables can cause errors).
• 🚫 Disable the antivirus – it can block the Mi Unlock Tool.

After installation:

1. Launch the utility on behalf of the administrator.
2. Sign in with the same Mi Account as you do on your phone.
3. Connect your phone in Fastboot mode (turn off the device, then press Volume Down + Power).

Step 3: Request and Wait for Code

If all conditions are met, the utility will show a message:

⚠️ Warning: Your device is linked to your account and requires 72-720 hours (3-30 days) to unlock depending on your model and account history.

Waiting times in 2026:

The counter starts only after the first successful connection to the Mi Unlock Tool, and if you interrupt the process or untie the account, the counter will reset!

💡

If the utility gives you a "Couldn't verify device" error, try using another one. USB-port (preferably) USB 2.0) or disable the driver signature in Windows via the bcdedit command /set nointegritychecks on (administrator rights required).

Alternative Unlocking Methods (for Power Users)

If the official method doesn’t work (for example, due to account lockdown or lack of waiting), there are workarounds that require technical skills and carry risks!

Method 1: Unlocking with EDL (Emergency Download Mode)

EDL is a service mode that allows you to flash your device directly through the Qualcomm port.

• 🔧 Auth file (a unique key for your model, sold on forums like XDA Developers).
• 💻 Mi Flash Pro or QFilm.
• 🔌 USB-to-EDL cable (or the ability to enter a device into a device) EDL testpoint).

⚠️ Attention: Use EDL Without an auth file, it can lead to complete blocking. IMEI (The device will become a “brick” without the possibility of recovery).

Method 2: Exploits for older models

Some devices running MediaTek processors (such as Redmi 9A or POCO C3) can be unlocked through vulnerabilities in the bootloader.

• 🛠️ MTK Bypass Tool – bypasses the Mi Account check on MediaTek chips.
• 🔓 SP Flash Tool – allows you to flash a custom preloader to unlock.

🔹 Important: These methods only work on firmware older than 2022. MIUI They have closed most of the vulnerabilities.

Method 3: Buying an unlocked bootloader

At sites like AliExpress or eBay, they sell turnkey unlocking services, which range from $5 to $50 depending on the model.

• 🕵️ Fraudsters can steal your Mi Account information.
• 🔄 There is no guarantee that the bootloader will remain unlocked after the update.
• 🚫 Xiaomi may block the device for using unofficial methods.

Frequent mistakes and their solutions

Even when you follow the instructions, users encounter errors.

If the utility gives an error 0x80070005, this is an issue with administrator rights: run the Mi Unlock Tool on behalf of the admin and temporarily disable account control (UAC).

💡

The most common mistake is not meeting the waiting period. Even if you unplug the account and re-link it, the counter will not reset, but will start again!

Xiaomi models with special unlock conditions

Some devices have unique limitations, such as:

• 📱 Xiaomi 13T/14 Series: Requires confirmation through SMS-code at the first request to unlock.
• 📱 POCO F5/F6: Block unlocking if the device is less than purchased 30 days ago.
• 📱 Redmi Note 12 (Global): can request additional verification through a photo of the box.

For devices with a Dimensity processor (for example, Redmi Note 12 Pro+), unlocking is possible only through EDL - the standard Fastboot does not work.

🔹 Tip: Before buying a custom firmware device, check its compatibility on forums XDA or 4PDA. Some models (such as the Xiaomi Civi 3) do not support unlocking at all.

What to do after unlocking the loader

When the finalmente bootloader is unlocked, you have new opportunities — but also new risks.

1. Install custom recovery (e.g. TWRP) to backup and install firmware. Instruction: fastboot flash recovery twrp.img fastboot boot twrp.img
2. Make a full backup through TWRP (Boot, System, Data) sections.
3. Check firmware compatibility on the XDA Developers website.

⚠️ Note: Once unlocked, Xiaomi can remotely lock the device if it detects the use of uncertified software. This applies to models with anti-rollback (for example, Redmi Note 11 and newer).

If you plan to return to the official firmware, use the world versions of MIUI (for example, V14.0.3.0.TMCCNXM for Redmi Note 12). Local firmware (for example, for China) can block the bootloader again.
