The message “Waiting for any device”** in the MiFlash or command line window when you run Xiaomi through Fastboot is one of the most common problems that users face when trying to reflash a smartphone, tablet or even a smartwatch brand. The error means that the computer does not see the connected device, although the cable is physically inserted and the drivers (seems) installed. 90% of the time the problem is solved without contacting the service center, but requires a systematic approach.
In this article, we will analyze all possible causes of the appearance of “Waiting for any device” – from the banal absence of drivers to hardware malfunctions of the controller. USB. You will get step-by-step instructions for each situation, including manual connection check commands, ways to bypass bootloader locks, and even brick recovery techniques. POCO X3 Pro where the error is often linked to Mi Account security policy.
Why is it called “Waiting for any device”?
The error signals that a firmware tool (MiFlash, Fastboot or ADB) cannot detect a connected Xiaomi device in Fastboot mode.
- 🖥️ Lack of drivers: Qualcomm is not installed HS-USB QDLoader 9008, ADB/Fastboot driver or version conflict.
The most common mistake is when you try:
- 📱 Swipe your smartphone through MiFlash (for example, after a failed update) OTA).
- 🔄 Unlock the bootloader in the official way through the Mi Unlock Tool.
- 🛠️ Restore the brick with fastboot flash or EDL.
Interestingly, on some models (for example, Xiaomi Mi 11 or Redmi K40), an error can appear even when connected correctly, if the system activates Anti-Rollback mode - protection against rollback on old firmware, in which case a special patch or firmware via EDL is required.
Connection Checking: Where to Start Diagnosing
Before you dig deeper, make sure the problem isn't the trivial stuff. Start by checking the physical connection:
- Change. USB-Use the original Xiaomi cable or certified cable USB Type-C with data support (not all charging cables are suitable!).
- Connect to another port. The USB 2.0 (black connector) on the back of the PC is preferably more stable than USB 3.0 (blue).
- Check the power. If you connect through a hub or laptop without power, try connecting directly to the system unit.
- Restart your PC and your device, sometimes it helps to shut down and reconnect the cable.
If after these manipulations the error remains, proceed to check the drivers.
☑️ Basic diagnostics of connection
To make sure that the device is defined by the system at all, run on the command line (Win + R → cmd):
fastboot devicesIf the list is empty, but the phone is in Fastboot mode (the Mi Bunny logo with the inscription FASTBOOT on the screen), the problem is precisely in the drivers or lock.
Installation and update drivers for Xiaomi
Without the right drivers, Windows won’t be able to “see” your device in Fastboot or EDL mode. Even if you’ve flashed your phone before, after the Windows update, drivers could fly off.
Method 1: Automatic installation via MiFlash
- Download the latest version of MiFlash from Xiaomi’s official website.
- Install the program and connect the phone in Fastboot mode.
- Run MiFlash – it will automatically prompt you to install the missing drivers.
Method 2: Manual installation through Device Manager
- Open Device Manager (Win + X → Device Manager).
- Find a device with a yellow exclamation point (usually under Other Devices or USB Controllers).
- Right-click → Update the driver → Search on this computer.
- Specify the path to the driver folder (usually C:\Program Files (x86)\Xiaomi\MiPhone\Qualcomm\Driver).
For models running on a Qualcomm processor (most Xiaomi/Redmi/POCO), be sure to install the QDLoader HS-USB Driver. It can be downloaded separately from resources like XDA Developers.
💡
If Windows blocks the installation of drivers, disable the digital signature verification: restart the PC with the Shift key pressed, select Diagnostic → Additional settings → Boot options → Disable the mandatory driver signature verification.
Unlocking the bootloader is a key step
If you see “Waiting for any device” when trying to flash your phone through MiFlash, but the drivers are installed, chances are you have a bootloader locked. Xiaomi locks it on all devices by default, and without unlocking firmware through Fastboot is impossible.
How to check the status of the loader:
fastboot oem device-infoIf the answer is Device unlocked: false, the bootloader is locked.
Official way of unlocking:
- Link Mi Account to your device in settings (Settings → Xiaomi Account).
- Enable OEM Unlock in Settings → For developers (if there is no item, tap 7 times on the Build Number in About Phone).
- Download Mi Unlock Tool from the official website.
- Log in to the tool and connect the phone in Fastboot mode.
- Press Unlock and wait until it is completed (can take up to 72 hours due to Xiaomi’s validation).
⚠️ Note: Some models (e.g. Redmi Note 12 or Redmi Note 12) POCO F5) When you unlock it, you reset all the data.
If the official method doesn’t work (for example, due to a Couldn’t unlock error), try the workarounds:
- 🔄 Use alternative versions of the Mi Unlock Tool (e.g. modified builds with the Mi Unlock Tool) XDA).
- 📅 Wait 7-30 days after account binding – Xiaomi can artificially delay unlocking.
- 🔧 Walk through. EDL (emergency mode) if the loader is completely blocked.
Firmware via EDL: When Fastboot doesn't work
If the phone is not detected even in Fastboot (for example, after a failed firmware or reset), then the last chance is EDL (Emergency Download Mode) mode, in which the device connects directly to the Qualcomm processor, bypassing the bootloader.
How to log into EDL:
- 🔌 Method 1 (software): Run the command: adb reboot edl (works if debugging is enabled) USB).
- 🔧 Method 2 (hardware): Close the Test Point contacts on the board (disassembly required). For each model, the points are different - look for diagrams on the board 4PDA or XDA.
- 📱 Method 3 (button combination): For some models (e.g., Redmi) 9A) — Hold the volume.+ + Volume-- and plug in the cable.
Once you log in to EDL, the device will be identified as Qualcomm HS-USB QDLoader 9008, which can be flashed through:
- 🖥️ MiFlash (select mode) flash_all_lock.bat loader-restore).
- 🛠️ QFil (a firmware utility for Qualcomm devices).
- 🐧 EDL Tool (for power users, supports unlocking without waiting).
⚠️ Attention: Firmware through EDL drop off IMEI After the procedure, you'll need to restore them through the QCN-file-menu.
What if the phone doesn’t turn on after EDL?
Firmware Mistakes: What to Do When Nothing Helps
If you’ve tried all the ways, but “Waiting for any device” still appears, note the common mistakes:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Device flashes in Device Manager, but is not detected in fastboot devices | Driver conflict or lack of power | Remove all Xiaomi drivers via USBDeview, install again, use USB 2.0 port |
| Fastboot devices show the device, but MiFlash is an error | Incompatible version of MiFlash or firmware | Use MiFlash 2020.3.14.0 for new models or MiFlash 2018 for old models |
| The phone vibrates when connected, but is not detected | The USB-C connector or controller on the board is damaged | Try connecting via EDL or contact the service |
| Remote: Device is locked | bootloader is locked, but Mi Unlock Tool won't unlock | Wait 7–30 days after you have an account attached or use EDL |
Critical information: If your device is Xiaomi Mi 11 Ultra, Redmi K50 or newer, the firmware through Fastboot can be blocked at the hardware level (Snapdragon 8 Gen 1/2 chip).
Alternative Firmware Methods Without Fastboot
If you can’t unlock the bootloader and EDL is not available, try alternative methods:
- 📦 Firmware via Recovery: Download firmware in.zip format for your model (e.g. fastboot) ROM recovery ROM). Rename the file to update.zip And put it in the root of the phone's memory.+ + Power to log in to Recovery. select Install update.zip and wait for completion.
Recoil through Mi Assistant
For some models (such as the POCO F3), Mi Assistant, the official system recovery utility, is suitable. It automatically downloads the firmware and flashes the phone around the Fastboot.
Firmware through ADB Sideload
adb sideload rom.zipIt works if USB debugging is enabled and the phone is booted into the system.
If none of these methods worked, the last option is to contact Xiaomi’s service center, and in some cases, such as when an eMMC chip is damaged, recovery is possible only through a soldering station.
💡
Before running through alternative methods, always check the firmware compatibility with your model! The wrong ROM can finally "brick" the device.
