Logging into a Xiaomi bootloader is a necessary skill for smartphone owners who want to install custom firmware, unlock the bootloader, perform a factory reset or restore the device after a failure. However, the process is different from the standard actions on other Android devices: there are nuances with button combinations, Fastboot and Recovery modes, and restrictions from the manufacturer.
In this article, we will discuss all the current ways to log in to the bootloader on Xiaomi, Redmi, POCO and Black Shark – from the classic “hot keys” to commands via ADB. Particular attention will be paid to the difference between models on Qualcomm and MediaTek processors, and also warn against typical errors that can turn a smartphone into a “brick.” If you plan to unlock the bootloader, here you will find instructions for preparing a Mi Account.
What is a Xiaomi bootloader and why you need it
A bootloader is a program that starts when you turn on your smartphone before the operating system boots up. On Xiaomi devices, it is responsible for:
- 🔐 Security: blocks unauthorized firmware changes (virus and custom software protection).
- 📱 Mode Selection: Allows you to switch between Fastboot (for PC firmware), Recovery (for resets and updates) and normal Android boot.
- 🔧 Recovery: Used to “resuscitate” the device after crashes or failed updates.
By default, the bootloader on Xiaomi is locked, which means that you will not be able to install alternative software (such as LineageOS or Pixel Experience) or even roll back the official firmware to the old version. Unlocking requires linking the device to the Mi Account account and waiting for permission from Xiaomi servers (usually 3-7 days).
It is important to understand that logging into a bootloader is not the same as unlocking it. You can log into Fastboot or Recovery even on a locked device, but installing unofficial software will require an additional procedure through the Mi Unlock Tool.
How to Sign In to Fastboot on Xiaomi
Fastboot is a bootloader mode that allows you to interact with your smartphone via a computer using fastboot commands (part of the Android SDK), which is required to unlock the bootloader, firmware through the Mi Flash Tool or install TWRP. You can log in in in three ways:
1. button combination (for switched off device)
The most versatile method, which works on 90% of Xiaomi, Redmi and POCO models:
- Turn off the smartphone (if it freezes – hold the power button for 10-15 seconds).
- Press the Power button + Volume down.
- Hold for 5-10 seconds until the Mi Bunny logo appears in the Ushanka cap (Fastboot mode).
☑️ Preparation for entrance to Fastboot
On some models (e.g. Xiaomi 12T or POCO F5), the combination may differ:
- 📱 Devices with Bixby button (rarely): Power + Loudness down + Bixby.
- 🔋 Smartphones without a physical home button: the standard combination + Loudness down.
- ⚡ Models with MediaTek (e.g. Redmi) 10A): Sometimes you need to connect. USB-cable to PC before pressing buttons.
2. Command via ADB (if smartphone is enabled)
If the device is working but you need to reboot to Fastboot without turning off (for example, to unlock the bootloader), use ADB:
- Enable USB debugging in the developer settings (Settings → About Phone → MIUI version – tap 7 times, then go back to Additional settings → For Developers).
- Connect your smartphone to your PC and open the terminal (or Command Prompt in the folder with ADB).
- Enter the command:
adb reboot bootloaderOnce executed, the device will automatically restart to Fastboot, a method preferred if the physical buttons are faulty.
3. Automatic reboot via menu (for unlocked devices)
If the bootloader is already unlocked, the option to switch to Fastboot may appear in the Recovery menu:
- Enter Recovery (Nutrition + Volume Up)
- Select Reboot → Fastboot (navigation with volume buttons, confirmation – power button).
💡
If your smartphone doesn’t respond to the button combination, try holding it for 15 to 20 seconds. Some models (like the Black Shark 5) require longer retention because of the protection from accidental login.
How to Sign In to Recovery Mode on Xiaomi
Recovery Mode is a recovery mode that allows you to reset settings, install official updates (OTAs) or clear cache. Unlike Fastboot, there is no direct access to firmware via PC, but you do not need to unlock the bootloader.
Standard button combination
For most Xiaomi devices (including Redmi Note 11, POCO X4 Pro, Mi 11 Lite):
- Turn off your smartphone.
- Press the Power button + Volume up.
- Hold on until the Recovery menu appears (usually with the Mi logo and the words No command in English or Chinese).
On some models (such as the Xiaomi Mi A3 or Android One devices), the Recovery menu can be in English and support touch input. On most Xiaomi, the control is carried out by the volume buttons (up/down) and power buttons (select).
Through ADB (if the smartphone is enabled)
Similar to Fastboot, Recovery can be rebooted with the command:
adb reboot recoveryThrough the settings menu (for MIUI)
If the device is working, but you want to reset your settings via Recovery:
- Open Settings → About the phone → System update.
- Slap the icon "⋮" (three points) in upper right corner.
- Select Reboot in Recovery.
What happens if Recovery does not open?
Features for different processors (Qualcomm vs MediaTek)
The method of logging in to the bootloader may depend on the type of processor in your device. Xiaomi uses chips from both manufacturers, and each has its own nuances:
| Characteristics | Qualcomm (Snapdragon) | MediaTek (Helio/Dimensity) |
|---|---|---|
| Combination for Fastboot | Food + Volume Down | Sometimes it requires a plug-in. USB-cable-to-button |
| Combination for Recovery | Food + Volume up | The same thing, but on some models (for example, Redmi 9A) can be triggered with a delay. |
| Support for EDL Mode | Yes (through port 9008) | Restricted (requires an authorized account) |
| Unlocking the bootloader | Through the Mi Unlock Tool | Often requires additional authorization on MediaTek servers |
For example, on the Redmi Note 10 Pro (Snapdragon 732G), Fastboot logs in as standard, while Redmi 10C (Helio G88) may require a PC pre-connection. If you’re not sure about the type of processor, check it in Settings → About Phone → Full Specifications or via the CPU-Z app.
💡
On devices with MediaTek, never interrupt the Fastboot firmware process – this can lead to a lock. DA-Authorization (service center required).
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes have problems logging in to the bootloader, and here are the most common errors and solutions:
⚠️ Warning: If this device is locked on the screen after logging in to Fastboot, it means that the bootloader is locked. Trying to flash custom software in this state will lead to a brick).
- 🔄 The device does not respond to the button combination: check if the smartphone is completely turned off (sometimes you need to remove and insert back the battery if it is removable, POCO X3 Pro) hold the buttons to double vibration.
- 🖥️ Computer doesn’t see device in Fastboot: install Mi drivers USB Driver and check the connection via port USB 2.0 (some PCs have problems with the system) USB 3.0 for Fastboot).
- 🔌 Charging less than 30%: Xiaomi blocks the bootloader entrance when the battery level is low. Charge the device to at least 40%.
- 🔒 Password required after resetting to Recovery: if the device was enabled Mi Account protection, after reset, you will need to enter the account data associated with the phone.
Another common problem is hanging on the Mi logo after a failed attempt to log in to Recovery.
- Shut off all cables.
- Hold the power button for 20-30 seconds (forced reset).
- Repeat the attempt to enter the loader.
Unlock bootloader: brief instructions
If your goal is to install custom firmware or TWRP, one login to Fastboot is not enough: you will need to unlock the bootloader.
- Linking your Mi Account to your device: 📱 Go to Settings. → Mi Account → The Mi cloud. 🔗 Make sure your device is linked to your account (under Devices").
Mi Unlock Tool
- 💻 Download the utility from the official website.
- 🔌 Connect your smartphone in Fastboot mode to your PC.
- 🔓 Run the Mi Unlock Tool and follow the instructions (you will need to log in to the same Mi Account).
⚠️ Note: After unlocking the bootloader, all data on the device will be erased, and the Xiaomi warranty will be canceled. L1 for Netflix HD) They may stop working.
If you unlocked the bootloader but want to get it back, it is only possible through the official firmware in Fastboot followed by resetting the unlock flag (on some models).
Additional Modes: EDL and Test Point
In addition to Fastboot and Recovery, there are hidden modes for advanced users and service centers on Xiaomi:
EDL (Emergency Download Mode)
This is an emergency boot mode that allows you to flash through the device even with a damaged bootloader, and it activates in different ways:
- 🔌 Short-circuit: Some models (e.g. Redmi Note 8 Pro) require Test Point to be closed on the motherboard.
- 💻 via the fastboot command (only for unlocked devices):
fastboot oem edlIn EDL mode, the device is defined as Qualcomm HS-USB QDLoader 9008. For firmware, you will need an authorized Xiaomi account and special tools (for example, Mi Flash Pro).
2. Test Point (Service Mode)
Used to force EDL login on locked devices, the method is risky and requires disassembling the smartphone:
- Turn off the device.
- Open the back cover (on most modern models it is glued).
- Find Test Point contacts on the motherboard (usually signed or marked as TP).
- Close them with tweezers or wires, simultaneously connecting USB-plug-in.
The dangers of using Test Point
These methods are recommended only for experienced users or service engineers. Fastboot is enough for normal firmware or unlocking a bootloader.
