When to reboot via Fastboot and how it differs from the usual
Did you hold the Xiaomi power button for more than 10 seconds, but the screen never caught fire? Or did the phone freeze on the MI logo and not respond to touch? In such cases, a standard reboot won't help - a forced reset via Fastboot mode is required. This method works even when the system is completely locked, but has its own nuances.
Fastboot is an engineering protocol built into a smartphone's processor at the hardware level. Unlike a conventional reboot (which runs through the MIUI operating system), here commands are sent directly to the bootloader.
- 🔄 Get out of the “eternal” hang on the screensaver Mi or POCO
- 🔧 Avoid Bootloop Errors (Cyclical Reboot)
- 🛠️ Prepare the device for firmware or unlocking the loader
- ⚡ Restore performance after a failed update
However, Fastboot is not a magic button – if the phone is physically damaged (e.g., the power controller is burned), this method will not work, nor will it help if the bootloader is blocked and you do not know the credentials of the Mi Account associated with the device.
Preparing for the reboot: what will be needed
Before you start, make sure you have:
- 🔌 Original. USB-cable (better from the Xiaomi kit – cheap often do not transfer data to Fastboot)
- 💻 Windows computer (7/10/11), macOS or Linux (more drivers will be required for Macs)
- 📱 Battery charge not less than 30% (ideally - 50%+)
- 🛠️ Utilities. ADB Fastboot (you can download from the official website of Android Developers)
Redmi Note 10/11/12, POCO F3/F4 and 2023-2026 innovations (e.g. Xiaomi 14) may require you to disable driver signature verification in Windows, otherwise the system will block the connection.

⚠️ Note: If the phone was bought from hand and tied to someone else's Mi Account, rebooting via Fastboot can start the verification procedure!
Step-by-step: how to log into Fastboot on Xiaomi
The method of entry depends on the condition of the phone:
| Condition of the telephone | Action | Notes |
|---|---|---|
| Phone's on, but it's getting stuck. | Press Power + Volume Down for 10-15 Seconds | Release buttons only after the Fastboot logo appears. |
| The phone is off but responds to charging | Press Volume Down, Then Connect the Cable to the PC | On some models (POCO X3) you need to hold both volume buttons. |
| Black screen, no reaction. | Connect to charging for 30 minutes, then try the button combination | If it does not help – a problem in the hardware (for example, a burnt plume) |
| Cyclical reboot (bootloop) | Wait for the vibrations to reboot and immediately press the Volume down. | You can hold the button until the Fastboot menu appears. |
The menu should appear on the screen with the words FASTBOOT and the image of a hare in a hat-eared hat (the official logo of the mode). If instead you see the recovery (Mi Recovery), then you held the Volume up, try again.

Reboot via Fastboot: commands and their value
When your phone is in Fastboot mode, connect it to your computer and follow the following steps:
- Open the command prompt (cmd) in the folder with ADB and Fastboot.
- Check the connection command: fastboot devices If the device is determined, you will see its serial number. If not, check the driver or cable.
- For a simple reboot, type: fastboot reboot
- If you need to reset the cache (helps when you freeze after the update): fastboot erase cache fastboot reboot
For Xiaomi 12T, Redmi K50 and later models, you may need to unlock OEM in the developer settings. If you did not activate it in advance, the fastboot oem unlock command will not work - the phone will request confirmation through Mi Account.
What if the fastboot device command doesn’t show the device?
⚠️ Warning: The fastboot erase userdata command will completely delete all data from the phone, including photos and apps! Use it only if other methods have not worked and you have a backup.
Common Mistakes and How to Fix Them
Even with the right actions, there can be failures.
- 🚫 FAILED (remote: 'Flashing is not allowed' means that the bootloader is blocked.
- ⏳ Waiting for device - phone not detected. Check cable, ports and drivers.
- 🔒 Device is locked - the device is tied to the Mi Account.
- 🔄 Cyclical reboot after fastboot reboot is a sign of a damaged boot partition.
If the phone is stuck on the logo again after the reboot, try flashing the stock firmware through the Mi Flash Tool.
- Download the firmware for your model from en.miui.com.
- Unpack the archive in a folder without Cyrillic characters.
- In the Mi Flash Tool, select Clean All mode.
💡
If after rebooting via Fastboot, the phone turns on, but constantly overheats - reset to factory settings through Settings → Additional → Restore and reset. This may be due to a conflict of system files.
Features for new Xiaomi models (2023–2026)
In the Xiaomi 13T, Redmi Note 12 and newer phones, the manufacturer has tightened control over the Fastboot.
- 🔐 Mi Account binding is required even for basic commands (for example, fastboot reboot may request confirmation).
- ⏱️ The waiting time for responses from Xiaomi servers increased to 30-60 seconds (previously 5-10 seconds).
- 🛡️ Block commands such as fastboot oem edl (transition to mode) EDL) without formal permission.
For these models, it is recommended to use authorized service centers if you are not sure about your actions. For example, a failed attempt to unlock the bootloader on Xiaomi 14 can lead to a complete IMEI lock.
💡
Starting in 2023, Xiaomi has implemented anti-Rollback protection, which blocks the firmware of older versions of MIUI. This means that a “rollback” to the previous firmware can permanently disable the phone.
Alternative Reboot Methods If Fastboot Fails to Work
If you can’t log in to Fastboot (for example, the volume button is broken), try:
- Hard Reset Recavator: Press Power + Volume up for 10 seconds. From the Mi Recovery menu, select Wipe Data → Wipe All Data. Confirm the action and wait for the reboot.
Use of test points (for advanced users):
On some models (Redmi) 9A, POCO M3) You can close contacts on the board for forced entry into the EDL-It's risky, because without experience, you can damage the motherboard!
Calling the service:
If the phone doesn’t respond to any combinations, there may be a problem with the PMIC (power controller) or eMMC (memory), in which case only the diagnostics on special equipment (DC Power Supply, eMMC Reader) will help.
