Fastboot mode on Xiaomi Redmi smartphones is a special engineering menu that allows you to perform low-level operations: unlock the bootloader, firmware through the Mi Flash Tool, restore the system after crashes or even bring the device back to life if it does not turn on. Without access to this mode, many service procedures are simply impossible.
However, Fastboot Mode is often difficult to log in to, and some people confuse it with Recovery Mode, some people canβt find the right button combination, and some people are afraid to accidentally reset. In this article, weβll look at all the current ways to log in to Fastboot on Redmi Note 12/11/10, Redmi A2/A1, POCO and other models β from the classic method with buttons to commands via ADB.
If you've never worked with Fastboot before, don't worry: it's not as hard as it sounds. The key is to follow the instructions and not miss important nuances. For example, on some Xiaomi models after 2022, the button combination changed due to the updated MIUI 14+ firmware, and the old ways may not work. We took all these points into account and collected only current methods.
Before proceeding, make sure that:
- π The battery level is not lower than 30% (ideally - 50%+).
- π If you use a cable, it must be original or high quality (cheap cables may not transmit data).
- π± The phone has disabled the function of Protection against accidental pressing (if it is in your model).
1 What is Fastboot and why is it needed on Xiaomi Redmi?
Fastboot Mode (or Bootloader Mode) is a protocol that allows you to interact with the Android device bootloader directly via your computer. Unlike Recovery Mode, where you can reset or install an update, Fastboot gives you access to deeper settings:
For example, it can:
- π Unlock the bootloader (a mandatory step before firmware custom software like LineageOS or Pixel Experience).
- π₯ Install official firmware via Mi Flash Tool (relevant if the phone doesnβt turn on or is stuck on the logo).
- π Restore IMEI, If it's gone after a failed firmware.
- π οΈ Check the condition of the section EFS (where the critical data of the communication module is stored).
On Xiaomi Redmi smartphones (as on other Mi/POCOs), the Fastboot looks like a black screen with a hare in a hat and the inscription FASTBOOT at the bottom. If you see the Mi logo or menu items in English, it's Recovery, not Fastboot.
β οΈ Note: Logining to Fastboot on a locked bootloader (which is blocked by default on all Xiaomi) will not give you full access to commands. ROM If you don't unlock it, you'll get permission from Xiaomi through the official Mi Unlock Tool.

βοΈ Preparation for entrance to Fastboot
Method 2: Entry through ADB (if the phone is switched on)
If your Redmi works but you need to upgrade to Fastboot without using buttons (e.g. to automate the process), you can do so through the ADB command.
- π₯οΈ Computers with installed ADB and Fastboot drivers.
- π USB-cable (preferably original).
- π± Included debugging by USB phone-on.
Step-by-step:
- Connect the phone to the PC and allow debugging over USB (a request will pop up on the smartphone screen).
- Open the Command Prompt (Windows) or Terminal (macOS/Linux) in the folder with ADB.
- Enter the command: Adb devices Make sure your device appears in the list.
- Run the command to go to Fastboot: adb reboot bootloader
The phone will automatically reboot to FASTBOOT mode, which is convenient if you need to switch between modes frequently (for example, when testing firmware).
β οΈ Note: If after the command adb reboot bootloader phone is stuck on the Mi logo for more than 5 minutes - this is a sign of a damaged bootloader. EDL (flash-fix).
π‘
If the adb command doesnβt work, check if Xiaomi drivers are installed on your PC. Download them from the official website or use the universal driver package from Google (Android SDK).
Method 3: Entering through the Mi Flash Tool (for "bricks")
If your Redmi doesnβt turn on at all (black screen, perpetual boot, bootloop error), but reacts to a PC connection (USB connection sound), you can try logging into Fastboot via the Mi Flash Tool.
- π Recovery after a failed firmware.
- π§ Fixing errors such as Invalid IMEI Baseband Unknown.
- π¦ Install official firmware if the phone is not loading.
Instructions:
- Download and install the Mi Flash Tool (the official utility from Xiaomi).
- Connect the phone to the PC without pressing the buttons.
- Run the Mi Flash Tool and press Refresh. if the device is determined as COM-port - it's in Fastboot mode.
- If not, press Power + Volume Down for 10 seconds, then release and press Refresh again.
If the phone is not detected even after that, it may be in EDL (emergency boot) mode, in which case you will need a special Deep Flash Cable cable or transition to EDL via test points (for power users).
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone vibrates, but doesn't come with the Fastboot | The bootloader or buttons are damaged. | Try to sign in via ADB or Mi Flash Tool |
| The screen flashes and goes out. | Weak battery. | Charge your phone to at least 50% |
| Recovery Menu Appears Instead of Fastboot | Wrong combination of buttons | Use Power + Volume Down, not Volume Up |
| PC doesn't see the device in Fastboot | There are no drivers. | Install Mi USB Driver or Google USB Driver |
5. Frequent mistakes and how to avoid them
Even experienced users sometimes encounter problems logging into Fastboot, and here are the most common errors and solutions:
πΉ The phone doesn't respond to the buttons.
- π Check battery power β at a level below 5%, the device may not turn on.
- π Try another one. USB-cable (cheap cables often don't transmit data).
- π οΈ If the buttons are physically damaged, use the method of using ADB (if the phone still turns on).
πΉ Recovery Menu Appears Instead of Fastboot
- You used Power + Volume Up instead of Volume Down.
- On some models (such as the Redmi Note 10 Pro), after prolonged button retention, Recovery can be triggered.
πΉ PC doesn't see phone in Fastboot
- Install Xiaomi USB Driver or Google Android USB Driver.
- Try another one. USB-port (preferably) USB 2.0, because USB 3.0 sometimes conflicts).
- In Device Manager, check if the phone is displayed as an Unidentified Device (you need to update the driver manually).
β οΈ Note: If you see the status of the device is locked after logging in to Fastboot, it means that the bootloader is locked. You can only unlock it through the official Mi Unlock Tool, linking the Mi Account to the device.
π‘
If the phone is not included in the Fastboot in any way, the bootloader is likely damaged, in which case only the firmware through EDL (emergency mode) using an authorized Xiaomi account will help.
6 What to do if the Fastboot doesn't work
If none of these methods worked, here is the algorithm:
1. Check the hardware:
Connect your phone to charge for 30 minutes (the battery may be completely drained).
Try a different cable and a different computer (if you use a PC).
If the phone fell or got wet, it may be damaged motherboard.
2. Try alternative button combinations:
Some models (e.g. Redmi K50) have Power + Volume Up + Volume Down (hold 15 seconds).
For older models (Redmi 4X, Redmi 5A) sometimes Power + Volume Up helps, but this is rare.
3. Use test points for EDL:
If the phone doesn't respond at all, you can try EDL mode by closing the contacts on the board, which requires disassembling the device and is only suitable for advanced users.
For the Redmi Note series, testpoints are usually under the back cover, next to the battery (look for EDL or TEST labels).
4.Please contact the service center:
If the phone is not switched on and detected by the PC, the eMMC chip or power controller may be damaged, in which case only professional repair will help.
π‘ Useful tip: If you plan to work with Fastboot often (for example, for custom firmware), buy Deep Flash Cable for Xiaomi. EDL without disassembly, which makes it easier to recover from failures.
