Unlocked Xiaomi bootloader: what it means, pros and risks

If you own a Xiaomi smartphone, you've probably come across the term unlocked bootloader, a theme that's surrounded by myths: some people say you can't install custom firmware without unlocking, others warn you of losing warranty and building blocks. Let's get to the bottom of what's really behind it and why it's so important to Android enthusiasts.

A bootloader is a low-level software that starts when the device is turned on and is responsible for loading the operating system. By default, Xiaomi blocks the bootloader on all its smartphones to protect users from accidental system damage and unauthorized changes. However, unlocking opens up access to advanced customization options, but also carries certain risks.

In this article, we will take a look at what unlocked bootloaders give, how to test them, what Xiaomi models support the procedure, and what to do if you accidentally lock the device after the upgrade, and how to get around the manufacturer’s restrictions and what alternatives are available for those who do not want to take risks.

What is a bootloader and why is Xiaomi blocking it?

The bootloader is the first code that runs when you turn on a smartphone, which checks the integrity of the system and transfers control to the Android kernel. Manufacturers, including Xiaomi, block the bootloader for several reasons:

• 🔒 Security: Protection against malware that could replace the system when booting.
• 🛡️ Stability: Preventing a “brick” (unworkable state) due to incorrect firmware.
• 📱 Ecosystem Control: Xiaomi wants users to use official software with their services.
• 💰 Warranty obligations: Unblocking often voids warranty.

However, blocking creates problems for enthusiasts who want to:

• 🔄 Install custom restoration (for example, TWRP).
• 📲 Switch to alternative firmware (e.g. LineageOS or Pixel Experience).
• ⚡ Get root rights for deep system setup.
• 🔧 Remove embedded apps (bloatware) from Xiaomi.

It’s important to understand that unlocking is not a “hack” but a legal procedure that Xiaomi officially supports (albeit makes it more difficult) and the manufacturer provides the Mi Unlock Tool, but imposes restrictions, which we’ll talk about later.

The pros and cons of an unlocked bootloader

Unlocking the bootloader opens up new possibilities, but it also carries risks. Let's weigh the pros and cons so you can make an informed decision.

Important: Unlocking a bootloader doesn’t mean automatically rooting or installing custom firmware — it’s just the first step. Once unlocked, you’ll still have to manually flash TWRP or Magisk, which requires additional knowledge.

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10 Pro) POCO F3) Unlocking the bootloader leads to blocking the broadband module (loss of Widevine) L1), Netflix and other services are no longer available. HD-permit.

How to check if the bootloader is unlocked on Xiaomi?

Before you start unlocking, make sure your bootloader is still locked. There are two reliable ways to check:

Method 1: Through fastboot mode

1. Turn off your smartphone.
2. Press the Power button + Volume down to log into fastboot.
3. Connect the device to the PC and type the command: fastboot oem device-info
4. If the answer is Device unlocked: true, the bootloader is unlocked.

Method 2: Through the Developer Settings

1. Activate Developer Mode: Go to Settings → About Phone → MIUI Version and tap 7 times on the build number.
2. Back to Settings → Additionally. → For developers.
3. Find the item "Mi Unlock status" if it is unlocked, you will see the corresponding inscription.

On some models (for example, Xiaomi 12T or POCO X5 Pro) the bootloader status item may not be available.

💡

If you see a waiting for device error when you enter the fastboot oem device-info command, install the Mi USB Driver drivers and check the USB connection (Transfer files mode is not suitable, you need Fastboot).

The official way to unlock the Xiaomi bootloader

Xiaomi provides the official unlock tool, the Mi Unlock Tool. However, the procedure has become more complicated than before: it now requires a binding Mi Account and waiting (sometimes up to 720 hours!).

Linking your Mi Account to your device|Enable debugging on USB|Permission. OEM-unlock|Download Mi Unlock Tool|Prepare the cable. USB (original!)-->

Step 1: Linking your Mi Account

Without a linked Mi Account, you can't unlock.

1. Go to Settings → Mi Account and log in.
2. Activate data synchronization (required!).
3. B Settings → Additionally. → For developers, turn on: 🔌 Debugging by USB 🔓 Unlocking OEM (OEM Unlocking)

Connect the device to the PC and confirm the debugging permission.

Step 2: Launch the Mi Unlock Tool

Download the latest version of Mi Unlock Tool from the official website (pay attention to the version - for new models you need an up-to-date utility).

2. Sign in with the same Mi Account as you do on your phone.
3. Turn your phone into fastboot (Power + Volume Down).
4. Connect the device to the PC and wait until the program determines it.
5. Press Unlock and confirm the action.

At this point, you may see a message telling you to wait 168, 360, or even 720 hours (up to 30 days!) This Xiaomi deliberately delays the process to weed out random users.

⚠️ Warning: If you see a Couldn't unlock error or Current account is different from the account info on the device, then Mi Account is not properly linked.

Why Xiaomi has to wait 720 hours and how to get around it

Since 2021, Xiaomi has tightened its unlock policy by introducing a mandatory wait.

• 🛡️ Theft protection: the thief will not be able to quickly unlock the stolen phone.
• 📉 Reducing the number of “bricks”: users will have time to change their minds.
• 💼 Maintaining control over the ecosystem: fewer users will go to custom firmware.

The waiting period depends on the model and the region:

• 📱 Older models (until 2019): 72–168 hours.
• 📱 New models (2020–2023): 360–720 hours (up to 30 days!).
• 📱 Flagships (Xiaomi 13, 14): Sometimes blocking is not possible.

Is it possible to get around the wait? Technically, but it's risky.

Official bypass is only possible for older models (e.g. Redmi Note). 4X or Mi A1), There's no waiting, on new devices (POCO X6 Pro, Redmi Note 13 will have to wait.

💡

Even after unlocking the bootloader, Xiaomi can block it again when installing the official one. OTA-To avoid this, disable automatic updates or use custom firmware without anti-rollback.

What if the phone doesn’t turn on after unlocking?

One of the most common problems is a brick after unlocking or firmware, and the reasons can be different:

• 🔌 Interrupted unlocking process (cable disconnected or battery sat down).
• 📥 Incorrect firmware (for example, trying to install Global) ROM Chinese-style).
• 🔧 Anti-rollback version conflict (firmware older than current version).

If the phone doesn’t turn on, try the following steps:

1. Hard Reset (Hard Reset)
