Why Fastboot is the only way to log into the recavator on a locked Xiaomi
If your Xiaomi smartphone stopped booting, stuck on the logo or requires a reset, but the standard key combinations (Power + Volume Up) do not work - the only way out is to use the Fastboot mode. This low-level access mode allows you to control the device through the computer, even if the screen does not respond or the system is damaged. Unlike the classic reset (where you can make a reset through the menu), Fastboot Recovery on Xiaomi requires pre-unlocking the bootloader and working with ADB commands.
The main problem is that users don't understand the difference between Fastboot and Recovery Mode. The first one is for firmware, unlocking and recovery via PC, the second one is for manual reset right on your phone. If your Redmi, POCO or Mi isn't part of a regular recovery, then the bootloader is locked, and you can't do without Fastboot. In this article, we'll go through the whole process from preparing drivers to commands to restore the system.
⚠️ Critical warning: Incorrect commands in Fastboot can turn a smartphone into a brick. For example, a fastboot erase userdata command without further firmware will result in data loss and a download cycle. If you are a beginner, follow the instructions Step-by-step, without missing the bootloader unlock check.
What you need to enter the Recovery through Fastboot
Before you start the receptacles, make sure you have everything you need, and without the right tools, the process will end up in error or damage the system.
- 📱 Xiaomi smartphone with a battery charge of at least 50% (when discharged during firmware, the device may fail).
- 💻 Computer running Windows 10/11, macOS or Linux (more drivers will be required for Macs).
- 🔌 Original. USB-cable (cheap cables often don’t transmit data to Fastboot).
- 🛠️ Tools: Mi Unlock Tool (to unlock the bootloader) ADB & Fastboot Tools (platform tool package from Google) Xiaomi Flash Tool (if you need firmware)
You can download official utilities from the Xiaomi website or through Android Studio.Please note: for models POCO F5, Redmi Note 12 and later, you may need a Mi developer account with a connection to the device.
Step 1: Check the status of the bootloader (Locked/Unlocked)
The first thing to do is check if the bootloader is unlocked on your Xiaomi. If it is locked, you can’t log into the recavator via Fastboot without officially unlocking it.
How to find out status:
- Turn off the phone.
- Press Power + Volume Down before the Fastboot logo appears.
- Connect the device to your PC and open the Command Prompt (CMD) in the folder with ADB.
- Enter the command: fastboot oem device-info
In the answer, find the lines:
- Device unlocked: true – the bootloader is unlocked (you can continue).
- Device unlocked: false – bootloader is locked (you need to unlock through Mi Unlock).
What happens if you run a blocked bootloader?
Step 2: Unlock the bootloader through the Mi Unlock Tool
If the bootloader is locked, it must be officially unlocked. Xiaomi requires:
- Link your Mi Account to your device (in settings: Account → Mi Account → Link your device).
- Enable OEM Unlock in Settings → For Developers
- Wait 7 days after the link (a mandatory requirement for new accounts).
After preparation:
- Download Mi Unlock Tool from the official website.
- Open the utility, log in to your Mi Account.
- Connect your phone in Fastboot mode and follow the program instructions.
⚠️ Attention: Unlocking erases all data from the device! Also after the procedure, Anti-Rollback protection can work, blocking the rollback to older versions of the firmware.

Step 3: Fastboot commands to enter the Recavery
When the bootloader is unlocked, you can proceed to the launch of the Recovery.
- Check the connection of the device: fastboot devices (should display the serial number of the phone).
- Run the temporary recavers (without firmware): fastboot boot recovery.img (where recovery.img is a custom recavery file, for example, TWRP).
- Or reboot directly to the standard recavator: fastboot reboot recovery
If the fastboot reboot recovery command is not working (the phone is loaded into the Fastboot again), then the recovery section is damaged.

fastboot reboot recovery| Team team. | Description | When to use |
|---|---|---|
| fastboot reboot recovery | Reboot to standard recaverie | If the Recovery section is not damaged |
| fastboot boot recovery.img | Loading temporary Recovery (without firmware) | To test TWRP or other recoveries |
| fastboot flash recovery recovery.img | Recovery firmware in the section | If the standard recavery does not start |
| fastboot erase recovery | Removal of current Recovery | Before the new firmware (caution!) |
💡
If the fastboot reboot recovery command returns to Fastboot, try flashing the standard recovery for your model first. recovery.img file-back).
Solving errors when entering the Recovery through Fastboot
Even with the right commands, the process can end in error.
- 🚫 FAILED (remote: 'unknown command') Reason: Outdated version of Fastboot or drivers.Solution: Update ADB until the latest version or manually install drivers through Device Manager.
- 🔒 FAILED (remote: 'Flashing is not allowed in Lock State') Reason: bootloader is blocked.Solution: Unlock it via Mi Unlock Tool (see Step 2).
- 🔌 Waiting for device Reason: PC can't see phone Solution: Check cable and port USB. Reinstall the drivers ADB. Try another computer.
If the fastboot reboot recovery command leaves the phone in reboot but doesn't go into the recovery, it's damaged.
- Download the official firmware for your model from the Xiaomi website.
- Remove the recovery.img file from the archive.
- Fastboot flash recovery recovery.img
💡
If the phone still doesn’t boot after you have recovered, check the integrity of the recovery.img file. A damaged image can cause a logo to freeze or a cyclic reboot.
What to do if the recavator does not start even after the firmware
If all the commands are executed correctly, but Xiaomi stubbornly does not enter the Recovery, the reasons may be more serious:
- 🔧 In this case, only the full firmware through Fastboot command will help: fastboot flash boot boot.img
- 🛡️ Anti-Rollback protection activated: If you try to flash the old version of the recovery to a new model (for example, Redmi Note 11 on the firmware from the Note 10), the system will block the download.
To diagnose hardware problems, enter the command:
fastboot getvar allPay attention to the parameters:
- Battery-voltage – if the value is 0, the battery is faulty.
- secure: yes – the bootloader is locked at the hardware level (you need an official unlock).
