Why the smartphone is stuck in Fastboot and what it means
Fastboot mode on Xiaomi Redmi Note 9 is a special state of the device designed to firmware, unlock the bootloader or restore the system via the PC. Normally, the smartphone should leave it automatically after execution of commands or after 30 seconds of inactivity. But what if the screen with a bunny (Mi Bunny) and the inscription FASTBOOT does not disappear for hours?
The causes of the freeze range from software failures to hardware problems, most often to blame: an interrupted firmware update, incorrect firmware through the Mi Flash Tool, conflict after unlocking the bootloader or even a banal battery discharge during critical operations. It is important to understand that the Redmi Note 9 (codenamed Merlin) uses a unique version of the Fastboot with protection from random commands, so standard exit methods may not work.
Before you panic, check:
✅ Is the smartphone connected to charging (charging indicator should burn).
✅ Is the physical button Volume Down pressed (button sticking is a common problem after falls).
✅ Are there any additional errors on the screen (such as critical error or invalid boot image).
Method 1: Standard button exit (without PC)
If your smartphone is responsive to physical buttons, try the classic method, which works in 60% of cases when the freeze is caused by a temporary failure, not a firmware damage.
Instructions:
1 Hold the Power button for 10-15 seconds until the screen goes out.
2.If the screen is turned off, release the Power and immediately press the Power + Volume Up combination for 5-7 seconds.
3. Wait for the vibration or the appearance of the MI logo - this is a signal to exit Fastboot.
Make sure the battery is at least 30 times charged%|
Turn it off. USB-smartphone-wire|
Check if the Volume Down| button is stuck
Wait 1 minute after pressing the buttons (sometimes the output takes time)-->
⚠️ Warning: If you reboot your smartphone to Fastboot again, the problem is deeper, maybe the boot or recovery partition is damaged, and you need to flash it again.
Method 2: ADB and Fastboot commands (for power users)
If the buttons don’t help, connect the Redmi Note 9 to your PC and use the ADB/Fastboot tools.This method requires drivers installed and minimal command line knowledge.
Steps:
1. Download Google’s Platform Tools and unpack the archive.
2. Connect your smartphone to your PC via the original cable (important!).
3. Open the command line (cmd) in the folder with the platform-tools and type:
fastboot devicesIf the device is determined (the serial number will appear), do:
fastboot rebootIf the team doesn’t work, try an alternative:
fastboot continueWhat if the PC can’t see the device?
⚠️ Note: The fastboot continue command may not work on the locked bootloader, in which case you will need to unlock through the Mi Unlock Tool, which will reset all data!
Method 3: Reboot via Mi Flash Tool (if the firmware is damaged)
If the smartphone is cyclically returned to Fastboot, the firmware is likely damaged, in which case a full flashing through the official Mi Flash Tool will help.
Step-by-step:
1. Download the firmware for Redmi Note 9 (select the Fastboot version, not Recovery!).
2 Unpack the archive into a folder without Cyrillic characters (e.g., C:\ROM\merlin).
3. Install the Mi Flash Tool and run it on behalf of the administrator.
4. Connect the smartphone in Fastboot mode and press Refresh - the device should be determined.
5. Select the firmware folder and press Flash. Select the clean all option.
| Firmware option | Effects of consequences | When to use |
|---|---|---|
| clean all | Complete reset, deletion of all data | In case of critical firmware errors |
| clean all and lock | Reset + lock loader | If you want to return the device to the "factory" state |
| save user data | Saving user data | Only if you are sure that the problem is not the data. |
⚠️ Note: Firmware via the Mi Flash Tool with the clean all option will delete all data, including photos and apps. If your smartphone had important files, try the non-reset methods first (Methods 1–2).
💡
Before you run the firmware, check the firmware version on Xiaomi’s official website. Installing an older version (downgrade) on a locked bootloader can result in a “brick” (complete inoperability) of the device.
Method 4: Use of EDL (Emergency Firmware) mode
If none of these methods worked, the last option is EDL-mode firmware, which works even on "brick" devices, but requires a special cable or short circuit of the contacts on the board.
Instructions for experienced users:
1. Download firmware in.mbn format (for example, through XiaomiTool V2).
2. Connect your smartphone to your PC by holding the Volume Up + Volume Down buttons (some versions of the Redmi Note 9 require the testpoints to be closed).
3. In the Mi Flash Tool, select firmware and press Flash.
4. wait until the process is completed (the process can take up to 10 minutes).
⚠️ Attention: Misuse of the right EDL-If you're not sure what you're doing, you can go to the service center, and if you don't have experience, closing the test points can damage the motherboard!
💡
EDL-The mode is a "resuscitation" for smartphones that do not respond to any other methods. Use it only as a last resort and with a full understanding of the risks.
Method 5: Alternative methods (if nothing works)
If all of the above methods did not work, try the following options:
- 🔋 Charging in the off state: Connect the smartphone to the original charger for 1-2 hours. Sometimes the discharged battery blocks the exit from the Fastboot.
- 🔄 Reset via Recovery: Try logging into Recovery Mode (Power buttons) + Volume Up) and make Wipe Data. If Recovery doesn't load, the problem is the firmware.
- 📱 Connecting to another PC: Sometimes drivers on one computer conflict. Try repeating steps on another device.
- 🛠️ If the smartphone does not respond to anything, it is possible that the motherboard or memory (eMMC) is damaged.
⚠️ Note: Redmi Note 9 with MediaTek Helio processor G85 (Not Snapdragon, some Fastboot commands may work differently. Clarify the processor model in the documentation or through the Mi Flash Tool before the firmware.
Frequent Mistakes and How to Avoid Them
Many users make the same mistakes when trying to log out of Fastboot.
- 🚫 Use of non-original cables: Cheap USB-The cables don't have to transmit data, only charge. Always use the original Xiaomi cable.
- 🔌 Unstable power: Connect your smartphone to the back port of your PC or laptop with charging. USB-Hubs often don't give enough current.
- 📥 Download firmware with number: Firmware from sites type 4pda You can always get the official version from c.mi.com.
- ⏳ Impatient: Some operations (such as fastboot flash) can take up to 5-10 minutes.
If the Redmi Note 9 is still stuck in Fastboot after all the manipulations, check out:
Does the red indicator on the screen (bootloader damage signal)
- Is there any physical damage (bloated battery, traces of oxidation on the board).
- Is the device correctly defined in Windows Device Manager (should be Android Bootloader Interface).
