Fastboot mode on Xiaomi smartphones is a special engineering mode that allows you to perform low-level operations with the device: flash custom recovery, unlock the bootloader, install official / unofficial firmware or restore the phone after serious failures. Without access to the Fastboot, you can not unlock the bootloader (a mandatory step for installing TWRP or LineageOS), as well as solve many problems when the system does not boot.
Unlike Recovery mode, where interaction is done via touch screen, Fastboot is managed via ADB and Fastboot commands from a computer. This makes the mode a powerful tool, but also requires caution: improper actions can lead to a “brick” of the device (complete failure without the possibility of recovery through standard methods). In this article, we will discuss all the current ways to log into Fastboot on Xiaomi, including the models of Redmi, POCO and Black Shark, and also consider typical errors and their solutions.
What is Fastboot and Why You Need It on Xiaomi
Fastboot mode (not to be confused with Fast Boot, Android’s fast boot function) is a bootloader-level protocol between the device and the computer that is activated before the operating system is launched and allows you to:
- 🔓 Unlock the bootloader through the official Mi Unlock Tool.
- 📱 Switch official and custom firmware (for example, Xiaomi.eu or Pixel Experience).
- 🛠️ Restore the device after failures when the system is not booting (the “brick»).
- 🔄 Install custom recovery (TWRP, OrangeFox).
- 📡 Check the status of unlocking the bootloader with the command fastboot oem device-info.
On Xiaomi, Fastboot entry is different from other brands (such as Samsung or Google Pixel) due to the features of the Qualcomm or Mediatek bootloader used in devices.
⚠️ Note: On new Xiaomi models (released after 2022), unlocking the bootloader via Fastboot can lead to loss of warranty and blocking some features (e.g., Widevine). L1 viewable HD-content).
Fastboot mode is often confused with EDL Mode (Emergency Download Mode) – these are different things. EDL is used for firmware through specialized boxes (for example, Mi Flash Pro) and requires an authorized Xiaomi account, whereas Fastboot is available to anyone.

Method 4: Alternative button combinations for new models
On some Xiaomi devices from 2023 to 2026 (e.g. Xiaomi 14 Ultra, Redmi Turbo 3, POCO F6 Pro), the standard Volume Down + Power combination may not work.

|---|---|---|
| Xiaomi 13T/14 | Volume Up + Power (hold 20 seconds) | Can open Recovery, then select Reboot to Fastboot |
| Redmi Note 13 Pro+ | Volume Down + Volume Up + Power | It only works on a switched-off device. |
| POCO F5 | Volume Down + Power (30 seconds) | If it doesn’t work, try connecting the charger. |
| Black Shark 5/6 | Volume Down button + double pressing of Power | Specific for gaming smartphones |
If neither combination works, check:

- 🔌 USB-cable – some cables block hardware buttons when connected.
- 🛠️ Physical damage – if the phone fell, the button socket could have been damaged.
