“Mi Unlock is unlocked”: what does this status mean on Xiaomi smartphones and why you need it

Introduction: Why the status of the bootloader is important for Xiaomi owners

If you've ever tried to install custom firmware, get root rights, or even just update software on a Xiaomi smartphone via fastboot, you've probably come across the term "Mi Unlock" -- the company's official tool for unlocking the bootloader. Unlock status in this context means that the manufacturer has removed software restrictions to allow you to modify the system files of the device. But what does it do in practice? And why do some users specifically strive for this, and others, on the contrary, avoid it?

In this article, we will discuss what exactly lies behind the phrase “Mi Unlock is unlocked”, how to check the current status of the bootloader on your Redmi, POCO or Mi, what opportunities open up after unlocking – and what risks it carries. We will pay special attention to the nuances of security, since an unlocked bootloader can become a “loophole” for attackers if you do not follow the basic rules.

Spoiler: If you don't plan on installing alternative firmware or getting root, you probably don't need to unlock it, but knowing the topic will help you avoid mistakes when buying used devices or experimenting with software.

What is Mi Unlock and why Xiaomi is blocking the bootloader

Mi Unlock is Xiaomi’s official utility for unlocking the bootloader on the brand’s smartphones. The bootloader is a low-level software that runs before Android boots and controls which kernel and firmware to download. By default, all Xiaomi devices (beginning with the Mi 5 and Redmi Note 3) have locked the bootloader, a security measure designed to:

🛡️ Protect against viruses: blocked bootloader will not allow malware to replace system files.
🔒 Prevent data theft: without unlocking, an attacker will not be able to install custom software to bypass protection.
📱 Keep warranty: Official service centers may refuse repairs if they detect an unlocked bootloader.
🔄 Ensure stability: inexperienced users will not be able to accidentally “kill” the device with incorrect firmware.

However, blocking creates problems for enthusiasts who want to:

🔧 Install custom software (such as LineageOS or Pixel Experience).
👾 Get root rights for deep system setup.
🔄 Update the firmware via fastboot if OTA-updates are not available.
📱 Restore the “brick” (defaulting device) after a failed firmware.

This is why you can unlock the Mi Unlock Tool, but it is important to understand that when you unlock the device, it becomes more vulnerable, and some features (for example, Mi Pay or Widevine) are more vulnerable. L1 viewable HD-Content may stop working.

How to check the status of the bootloader on Xiaomi: 3 working methods

Before unlocking the bootloader, you need to know its current status, and here are three reliable methods that work on most Xiaomi, Redmi, and POCO devices (including the 2023-2026 models).

Method 1: Fastboot (most reliable)

This method works even on “bricks” (non-booting devices), you will need a computer with ADB/Fastboot drivers installed.

Turn off your smartphone.
Press the Power Button + Volume down until the Fastboot logo appears.
Connect the device to the PC via USB.
Open the command line (Windows) or terminal (macOS/Linux) and type:

fastboot oem device-info

In the output, find the line Device unlocked: true, which means that the bootloader is unlocked. If false, locked.

💡

If the command doesn't work, try fastboot getvar unlocked. On some models (e.g. POCO F5), this request gives the same result.

Method 2: Through the Developer Settings

This method is simpler, but only works on bootable devices:

Activate Developer Mode: Go to Settings → About Phone → MIUI Version and tap 7 times on the build number.
Back to Settings → Additionally. → For developers.
Find Mi Unlock Status (or bootloader Status). If it's not available, use method 1.

Please note that on some firmware (e.g. global MIUI versions for Europe) this item may not be available due to Xiaomi’s policy.

Method 3: Through Third-Party Developer Apps

Google Play has utilities like Bootloader Status Check or MIUI Hidden Settings that show the status of the bootloader.

⚠️ Note: Not all apps work correctly on new Xiaomi models (e.g. Redmi Note 13 Pro)+ Xiaomi 14, or Xiaomi 14. Use fastboot for accuracy.

Method	Does it work on locked devices?	Wants a PC?	precision
fastboot oem device-info	✅ Yes.	✅ Yes.	100%
Developer settings	❌ Not (only if the mode is on)	❌ No.	90% (depends on firmware)
Third-party annexes	❌ No.	❌ No.	70% (may be wrong)

What gives the unlocked bootloader: opportunities and limitations

Unlocking the bootloader opens up a lot of customization options, but it also imposes a number of limitations. Let's look at both sides of the coin.

✅ What becomes available after unlocking

📱 Install custom firmware: LineageOS, Pixel Experience, Havoc-OS and others. This allows you to upgrade outdated devices (for example, Redmi Note 8 Pro) to new versions of Android.
🔧 Getting root rights through Magisk or SuperSU, which gives you control over system files, the ability to remove embedded applications and configure the kernel.
🔄 Brick Recovery: If the device doesn’t turn on after a failed update, an unlocked bootloader lets you flash it through fastboot.
🎯 Installation of custom cores to overclock the processor or improve autonomy (for example, FrancoKernel for POCO F3).
🔒 Overcoming restrictions MIUI: For example, disabling ads in system applications or removing Mi Browser.

❌ Limitations and risks

🚫 Loss of warranty: Xiaomi’s official service centers may refuse repairs if they detect an unlocked bootloader (even if the fault is not related to the software).
🔐 Security issues: Device becomes more vulnerable to viruses, especially if unofficial firmware is installed.
📺 Widevine's loss L1: On most devices after unblocking Netflix, Disney+ Other services will only show content in SD-quality (480p).
💳 Broken payment services: Mi Pay, Google Pay and banking apps can block work on unlocked devices.
🔄 Risk of bricking: One firmware error can turn a smartphone into a brick.Recovery will require fastboot skills and a fastboot. EDL.

💡

Unlocking the bootloader is irreversible: after it, you can not return the status of “locked” back without completely flashing through an authorized service center.

How to return the status of “blocked” back

Returning the factory status of the bootloader can only be through the official service center Xiaomi or authorized partners (for example, in Russia – through the “Svyaznoy Service”). Independently block the bootloader after unlocking is impossible – this is a technical restriction imposed by the manufacturer to combat fraud (for example, with stolen devices).

But there's a workaround, which is a complete flashing through fastboot or EDL modes using official software, and it won't bring back the "blocked" status, but it will allow you to:

🔄 Restore the device after “bricking».
📱 Install stock firmware without root and modifications.
🔒 Returning Widevine functionality L1 (sometimes).

For this:

Download the official firmware for your model from the MIUI Downloads website.
Unpack the archive and launch the script flash_all.bat (Windows or flash_all.sh (macOS/Linux).
Follow the instructions on the screen.

⚠️ Note: Flashing through fastboot erases all data, including internal memory (userdata!

Can I unlock the bootloader without waiting 168 hours?

No, it’s a technical limitation of Xiaomi, but some users report that older accounts (created before 2020) can be shortened to 72 or even 24 hours, and there are informal methods of bypassing EDL, but they require an authorized service center account and can lock the device permanently.

Why does Google Pay not work after unblocking?

The reason is because SafetyNet is Android security check, and the unlocked bootloader automatically fails this check, and to get Google Pay back on track, you need to: Install Magisk and activate Universal SafetyNet Fix. Hide the root status for banking applications through MagiskHide. Check SafetyNet manually (e.g., through the YASNAC app). Note that on some devices (e.g., Xiaomi 13T.), this method may not work due to hardware checks.
