Bootloader mode on Xiaomi smartphones is a special state of the device that allows you to install custom firmware, restore the system after crashes or obtain root rights. Without activating this mode, any manipulation of the firmware is blocked by the manufacturer. However, the process of transferring the phone to Fastboot Mode (as it is also called) often raises questions from the lack of reaction to buttons to errors when connecting to a PC.
In this article, we will discuss three official ways to launch Bootloader mode on Xiaomi, including the Redmi, POCO and Mi models (from Xiaomi 11T to Redmi Note 12). Particular attention will be paid to unlocking the OEM-unlock, a mandatory step for new devices that is often overlooked. You will also find solutions to typical problems: why the phone does not respond to Power + Vol Down, how to circumvent the Mi-account authorization requirement and what to do if the PC does not see the device in Fastboot mode.
What is Bootloader Mode and Why You Need It
Bootloader Mode (or Fastboot Mode) is a low-level smartphone state that is activated before the Android operating system boots. In this mode, the device can communicate with the PC via the Fastboot protocol, allowing:
- 📱 Install custom firmware (LineageOS, Pixel Experience, etc.)
- 🔓 Get root rights through Magisk or SuperSU
- 🛠️ Restore the phone after a "brick" (software failure)
- 🔄 Switch official updates manually (via Mi Flash Tool)
- 🔧 Unlock the bootloader for further modifications
On Xiaomi smartphones, Bootloader mode is blocked by default, this is done to protect against unauthorized access and prevent the installation of malware. However, for experienced users, such a lock becomes an obstacle.
- ❌ Install Google Camera (GCam) on models without official support
- ❌ Transfer applications to a memory card on devices with MIUI 12+
- ❌ Disable forced advertising in system applications
It is important to understand that unlocking Bootloader resets all data on your phone (including photos, contacts, and apps).So make sure to back up via Settings → Google → Backup or Mi Cloud before starting the procedure.
Method 1: Hardware method (Power + Vol Down buttons)
The easiest way to get Xiaomi into Bootloader mode is to use a combination of physical buttons, which works on 90% of models, including the Redmi Note 10 Pro, POCO X3 Pro and Mi 11 Lite. The main condition is that the phone must be turned off (not in sleep mode!).
Step-by-step:
- Turn off the smartphone with a long press on the power button (Power).
- Press and hold the Volume Down button.
- Without releasing Vol Down, press and hold the Power button.
- Hold both buttons for 10-15 seconds until the Mi Bunny logo appears on the screen in Fastboot mode.
If the screen is black or the Recovery menu appears (with the words "No command"), it means:
- 🔋 Battery discharged below 30% (charge your phone before trying again)
- 🔄 You let go of the buttons too early (repeat trying, holding on longer)
- 🔌 Use a non-original cable (try another one) USB-cable)
Battery charged >30%
The original cable (or quality analogue) is used
The phone is completely off (not in sleep mode)
Vol Down and Power buttons don't stick

⚠️ Note: On some models (POCO F2 Pro, Mi 10 Ultra) button combination may differ. + Vol Down is not working, try the Power. + Vol Up or Power + Vol Up + Volt Down at the same time.
Method 2: Recovery Menu (if phone is switched on)
If your Xiaomi is enabled but you want to upgrade to Fastboot Mode without using a PC, you can do so via the standard Recovery menu.This is suitable for devices with an unlocked bootloader or if you need to reflash your phone through the Mi Flash Tool.
Instructions:
- Turn off the phone.
- Press Power + Vol Up until the Recovery menu appears (usually with the words "No command" and a recumbent robot).
- On some models (Redmi 9, POCO M3) you must first select the language by clicking on the screen.
- In the Recovery menu, find Reboot to Bootloader (or Fastboot). Use volume buttons to navigate, power button to select.
If the Reboot to Bootloader item is not on the menu, it means:
- 🔒 bootloader is locked (you need to unlock through Mi Unlock Tool)
- 📱 You have custom Recovery (TWRP), wherein the item may be called differently
- 🔄 The firmware is modified (try the method with the ADB)
Once you select a point, the phone will automatically reboot to Fastboot mode. If that doesn't happen, try an alternative method via ADB (described below).
What happens if Recovery does not open?
Method 3: Through ADB (for advanced users)
Method by using ADB (Android Debug Bridge is suitable if the phone is turned on, but the hardware buttons do not work or you prefer to control the process from a PC. OEM-unlock.
What you need:
- 🖥️ Windows computer 10/11 or macOS/Linux
- 🔌 Original. USB-cable (preferably from the set)
- 📱 Included debugging by USB phone-on
- 🛠️ Installed drivers ADB/Fastboot mi PC Suite
Step-by-step:
- Download and install Platform Tools (the official Google package with ADB and Fastboot).
- On your phone, activate Developer Mode: Go to Settings → About Phone Press 7 times on MIUI Version until the notification “You’ve become a developer!” appears.
Settings for developers
- USB debugging
- Unlocking OEM (an important item!)
- Connect the phone to the PC and confirm the debugging request (on the phone screen).
- Open the command line (cmd) in the folder with Platform Tools and type: adb devices If the device appears in the list, type: adb reboot bootloader
After the last command, the phone will automatically restart to Fastboot mode. If no devices/emulators found error occurs, check:
- 🔌 Cable and port USB (Try another port or cable)
- 🖥️ Drivers installed ADB (Download the latest version)
- 📱 Is debugging on-line USB (Sometimes you need to reconnect the cable)
adb shell reboot bootloader
This command can work on some firmware where the standard method is blocked by the manufacturer.-->
Unlocking OEM: why it is impossible to flash the phone without it
Starting with MIUI 12, Xiaomi has introduced a mandatory bootloader binding to your Mi Account, which means that even if you successfully switched your phone to Fastboot mode, you will need to:
- Sign in to Mi Account on your phone.
- Connect your device to your account (in Mi Account → Mi Cloud settings).
- Activate OEM Unlock in the developer settings.
- Waiting 72–168 hours (up to 7 days) is Xiaomi’s requirement for new devices.
If you try to flash your phone right after you buy it, the system will give you an error:
Couldn't unlock. Please add your account in MIUI and wait for 168 hoursThis means waiting for the specified time, actively using the phone with the account tied.
| Xiaomi model | Whether waiting is required | Max, waiting time. | Is circumvention possible? |
|---|---|---|---|
| Redmi Note 12 Pro+ | Yes. | 168 hours | No. |
| POCO F5 | Yes. | 72 hours | Partially (via EDL) |
| Mi 11 Lite | Yes. | 72 hours | No. |
| Redmi 10C | No. | — | — |
| POCO X3 NFC | Yes (new devices only) | 72 hours | Yeah (through patch) |
⚠️ Note: Attempt to unlock the bootloader through informal methods (e.g, EDL) Newer models (Xiaomi 13, Redmi Note 12) may lead to lockdown IMEI. In this case, the phone will lose the network, and it can be restored only through an authorized service center.
