If you've ever tried to install custom firmware on a Xiaomi smartphone, you've probably come across the term "factory unlock." But what is it really like? Why do some users get it right away when they buy it, and others have to wait weeks or use workarounds? In this article, we'll look at what Xiaomi bootloader is factory unlocked, how it differs from the official procedure through Mi Unlock, and why this topic still raises so many questions in 2026.
It's worth clarifying right away: factory unlocking is not the same as unlocking through the Mi Unlock Tool. These are two fundamentally different approaches that lead to the same result: the ability to flash the device with unofficial firmware. But if official unlocking requires waiting, linking an account and sometimes even calling for support, factory unlocking is a kind of "loophole" that Xiaomi leaves for certain regions or batches of devices.
What is factory unlocking Xiaomi: definition and principles of operation
Factory unlock is a Xiaomi bootloader state in which it is already unlocked by the manufacturer during the production phase or first setup of the device.Such smartphones do not require a standard procedure through the Mi Unlock Tool and can be immediately stitched through fastboot or EDL (Emergency Download Mode).
Why is this happening? Xiaomi is shipping some of the devices to certain regions (like India, Indonesia, or Russia at some point) with the bootloader already unlocked.
- 📦 Local legal requirements (in some countries, a blocked bootloader is considered a restriction of user rights).
- 🔄 Returns policy – unlocked devices are easier to diagnose and reflash during warranty repair.
- 🛠️ Cooperation with local service centers that need the ability to quickly firmware.
It is important to understand that factory unlocking does not mean that there is no protection from unofficial firmware. The device still checks digital signatures when installing software, but the process of firmware via fastboot does not require binding to a Mi Account and waiting 7-30 days, as in the official unlock.
How to check if the bootloader is unlocked on your Xiaomi
Before you try to flash a device, you need to make sure that the bootloader is in a state, and you can do this in two ways:
- Using fastboot mode: Turn off your smartphone. Press Volume Down + Power until the Mi Bunny logo appears in the installer header. Connect the device to your PC and type in the command: fastboot oem device-info If you see the Device unlocked: true line in the answer, the bootloader is unlocked.
- Through Developer Settings (not working on all models): Activate Developer Mode: Go to Settings → About Phone → MIUI Version and tap 7 times on the build number. Return to Settings → Additional → For Developers. Find bootloader Unlock Status.
If both methods show that the bootloader is locked, but you are sure that you bought the device in the region with factory unlock (for example, the Redmi Note 11 for the Indian market), it is possible that the seller reflashed it to the global version of the software, which automatically blocked the bootloader.
💡
On some models (such as the POCO F3 or Redmi K40), factory unlocking may “disappear” after the MIUI update. Always check the bootloader status before you run the firmware, even if it has been unlocked before.
Factory vs. Official Unlocking: Key Differences
Many users confuse factory unlocking with official procedure through the Mi Unlock Tool. These are actually two different processes with different consequences.
| Parameter | Factory unlocking | Official Unlocking (Mi Unlock) |
|---|---|---|
| Is waiting required? | ❌ No, the unlock is done. | ✅ Yes (7-30 days of account binding) |
| Linking to Mi Account | ❌ Not required | ✅ Required. |
| Possibility of rollback | ⚠️ It can be blocked after the firmware official software | ✅ You can re-block it via fastboot oem lock. |
| Support OTA-update | ❌ Often breaks down after installing custom firmware | ✅ It works if you don’t install unofficial software. |
| Guarantee | ⚠️ Can be cancelled when the firmware is | ⚠️ It can also be cancelled. |
The main advantage of factory unlocking is instant access to firmware without waiting, but there are also disadvantages: such devices are more likely to face problems when upgrading through OTA, and some banking applications (for example, Sberbank Online or Tinkoff) can block work on them due to the changed status of the bootloader.
💡
Factory unlocking doesn't give you any additional rights than the official one, it just saves time, but it doesn't eliminate the risks of unofficial firmware installation.
What Xiaomi models most often come with factory unlocking
Not all Xiaomi devices can be factory unlocked, usually for models that are specific to specific regions, and here is a list of the most common cases:
- 📱 Redmi Note (especially Redmi Note) 10/11/12 for the Indian market — IN firmware).
- 🔥 POCO (multi-model POCO F and POCO X for the global market is supplied unlocked).
- 💎 Mi (less commonly found in Mi) 10T Mi 11 Lite for the European market).
- ⚡ Black Shark (Game smartphones often have an unlocked modding bootloader).
To see if your device is unlocked, look for the regional suffix in the firmware name:
- IN - India (high probability of factory unlocking).
- ID is Indonesia.
- RU - Russia (sometimes, but less often).
- EEA – Europe (usually blocked)
- Global version (depending on the party)
Example: If your Redmi Note 11 Pro+ 5G has firmware with the ING suffix (India + Global), the chances of factory unlocking are higher than that of the model with the EEA firmware.

Risks and pitfalls of factory unlocking
While factory unlocking seems convenient, it carries some serious risks that few warn of:
⚠️ Warning: Factory unlocked devices are more likely to be targeted by fraudsters, and attackers can refashion such smartphones with fake official software, masking stolen or faulty devices as them. IMEI pre-purchase!
Main problems:
- 🔒 Blocking banking applications – many financial services (including Google Pay) refuse to work on devices with an unlocked bootloader, even if it was unlocked in the factory.
- 🔄 Problems with OTA-updates – after installing custom firmware, the device may stop receiving official updates, and an attempt to return stockware sometimes leads to hard-brick (complete failure).
- 🛡️ Malware vulnerability – unlocked bootloader allows attackers to install modified firmware with backdoors.
- 📉 Reduced resale value – unlocked devices are cheaper in the secondary market due to the risks to the buyer.
Another nuance: Some models (such as the Xiaomi 12 Pro or Redmi K50 Pro) can automatically lock the bootloader after the MIUI update, even if it was initially unlocked in the factory, due to Xiaomi’s policy of tightening control over firmware.

How to return the official lock bootloader, if it was factory
If you want to return a device to a "locked" status (for example, to sell or use banking applications), you can do this, but the process is not always reversible.
- Download the official firmware for your model from the Miui Download website (choose the Fastboot version, not Recovery).
- Unpack the archive with firmware in a folder on the PC.
- Transfer the smartphone to fastboot mode (clip Volume down + Power).
- Connect the device to the PC and execute the command: fastboot flash lock bootloader.img (where bootloader.img is a file from the unpacked firmware).
- Then swipe the full firmware command: fastboot -w update name firmware.zip
After that, the bootloader must lock, but on some models (for example, the POCO X3 Pro or Redmi Note 10 Pro), this method does not work – the device may remain unlocked or even stop turning on, in which case you need firmware through EDL (and this requires an authorized Xiaomi account or contacting a service center).
⚠️ Note: On devices with Qualcomm processors (e.g., Snapdragon 860 in) POCO F3) Attempting to block the bootloader via fastboot can lead to loss IMEI. Always make a backup copy of the section modemst1 and modemst2 before manipulation!
