Why is your smartphone stuck in Fastboot Mode and what does it mean?
Fastboot Mode is an engineering mode on Xiaomi devices designed to firmware, unlock the bootloader or restore the system. On the Redmi Note 8 Pro (begonia model), it activates when holding the power + volume buttons while on. But sometimes the smartphone “hangs” in this mode for no apparent reason, showing on the screen a frozen robot Mi Bunny labeled FASTBOOT.
The main causes of the problem:
- 🔄 Interrupted update – if the firmware is through MIUI Updater or Fastboot was interrupted (battery was drained, disconnected) USB-cable).
- 🔧 Unlocking the bootloader - Mi Unlock Tool errors (especially if you didn't wait) 72/168 waiting-hours).
- 📱 Failure of the buttons - key sticking Reduced volume or damage to the plume.
- 💥 Boot section damage – after incorrect rooting or installing custom recavery (TWRP).
In 80% of cases, leaving Fastboot Mode does not require flashing, just perform the correct sequence of actions, but if the screen reads FASTBOOT: error: failed to boot or the device does not respond to buttons, more radical measures will be required.
Method 1: Standard button exit (works 60% of the time)
If your smartphone responds to physical buttons, try the classic method:
- Hold the Power button for 15-20 seconds until the screen goes out.
- Once the device is turned off, immediately press and hold Power + Volume Up (at least 10 seconds).
- Release the buttons when the MI logo appears, which means that the Redmi Note 8 Pro boots in normal mode.
⚠️ Note: If after these actions, it appears again FASTBOOT, So the problem is deeper, maybe the bootloader or the firmware is damaged.
Remember the current state of the screen (if there are any errors)
Check the battery charge (minimum 30%)
Turn it off. USB-cable (if connected to a PC)
Prepare the charger in case of resetting
-->
Method 2: Reboot via ADB (if the PC recognizes the device)
If Redmi Note 8 Pro is defined in Windows Device Manager as Android Bootloader Interface, you can send a reboot command via ADB:
- Download and install Platform Tools (the official tool from Google).
- Connect your smartphone to your PC through the original USB-cable.
- Open the command line (Win + R → enter cmd) and go to the folder with platform-tools: cd C:\platform-tools
- Enter the command: fastboot reboot
If the command is successful, the device will restart to normal mode. If there is a waiting for device error, check:
- 🔌 Cable and port USB (Try another port or cable).
- 🖥️ Are Xiaomi drivers installed (you can download on the official website).
- 🔄 Fastboot mode on the smartphone (should be active, the screen is not turned off).
💡
If the fastboot reboot command does not work, try fastboot continue – it forcibly continues to boot the system, ignoring the bootloader errors.
Method 3: Reset to factory settings via Mi Flash Tool (if other methods didn't help)
If the Redmi Note 8 Pro doesn't come out of Fastboot Mode and doesn't respond to commands, you'll have to reflash the device, which will delete all the data, but it will bring back the functionality.
Step-by-step:
- Download the official firmware for the Redmi Note 8 Pro (select the Fastboot version, not Recovery).
- Unpack the archive in a folder without Cyrillic characters (for example, C:\MiFlash\begonia_global_images...).
- Install the Mi Flash Tool and run on behalf of the administrator.
- Connect the switched off smartphone to the PC, holding Power + Volume Down (FASTBOOT should appear).
- In Mi Flash Tool, click Select, specify the firmware folder, then select Clean all (full reset) and click Flash.
| Type of firmware | Is the data preserved? | Firmware time | When to use |
|---|---|---|---|
| Clean all | ❌ No (full reset) | 5-10 minutes | If the device does not turn on or is stuck in FASTBOOT with an error |
| Clean all and lock | ❌ No. + lock-in | 7-12 minutes | If the unlocking of the loader caused a failure |
| Save user data | ✅ Yeah (saves files) | 3-5 minutes | Only if the system is loaded but is not stable |
⚠️ Warning: After the firmware Clean all will have to re-unblock the bootloader (if it was previously unlocked) and configure the smartphone from scratch.

Method 4: Using Test Point (the last method for bricks)
If the Redmi Note 8 Pro does not respond to any commands and is not detected in the Fastboot, the bootloader may be damaged, in which case Test Point, a special point on the motherboard, will help, the closure of which forcibly transfers the device to EDL (Emergency Download Mode) mode.
Attention! This method requires disassembling the device and risks voiding the warranty. Use only if other methods have failed.
Instructions:
- Turn off the smartphone (if it does not respond - wait for the battery to discharge completely).
- Remove the back cover (need a mediator and a hair dryer to soften the glue).
- Find Test Point on the motherboard (for the Redmi Note 8 Pro, these are two contact areas next to the battery signed by EDL or TP).
- Close them with tweezers or screwdrivers, simultaneously connecting USB-plug-in.
- If done correctly, Qualcomm HS-USB QDLoader 9008 will appear in Device Manager.
- Sweat the device through the Mi Flash Tool (select EDL firmware).
⚠️ Warning: Test Point failure can short circuit and cause the device to fail. If you're unsure of your skills, contact the service center.
💡
Test Point is the last chance to bring the brick back to life. If the device is not identified as a QDLoader 9008 after the circuit is closed, the problem may be a damaged memory (eMMC) or processor, and a replacement board will be required.
Method 5: Contacting the service center (guarantee and non-guarantee cases)
If all of these methods did not help, you can contact the authorized service center Xiaomi. the cost of repair depends on the cause of the malfunction:
| Problem. | A guarantee? | Cost of repair (approximately) | Timeline |
|---|---|---|---|
| Firmware failure (without physical damage) | ✅ Yes (unless there was a rooting) | Free of charge. | 1-3 days |
| Damage to the loader after unlocking | ❌ No. | 1 500–3 000 ₽ | 2-5 days |
| Button sticking or plume damage | ✅ Yes (unless there was an autopsy) | Free / 800-1 500 ₽ | 1-2 days |
| Damage to eMMC (memory) | ❌ No. | 3 000–5 000 ₽ (chip-change) | 5-10 days |
Before the service visit:
- 📄 Take a check or a warranty card (if any).
- 🔋 Charge the device by at least 50% (if it reacts to charging in any way).
- 📱 Remove your Mi Account from your device (if it’s even slightly powered on) to avoid activation issues after repairs.
If the warranty has expired, you can contact informal services - repairs can be cheaper, but the risk of using non-original spare parts is higher.
How to Avoid Fastboot Mode in the Future: 7 Rules
To avoid hanging out in Fastboot Mode, follow these guidelines:
- If you have started an update via MIUI Updater or Fastboot, wait until it is completed (even if it takes more than an hour).
- Use the original cables. Cheap. USB-cables can cause failures when firmware or charging.
- Don't unblock the bootloader unnecessarily. If you're not planning on installing custom firmware, it's best to leave it locked.
- For the Redmi Note 8 Pro, only firmware with the code begonia is suitable (not to be confused with begoniain for the Indian version!).
- Don't press the buttons at random. The Power + Volume reduction combination always leads to Fastboot.
- Keep an eye on battery power. If the charge is below 30%, the risk of failure when you update or update your firmware increases dramatically.
- Keep your data in the Mi Cloud or on your PC regularly, and it will save you when you reset it.
If you are actively experimenting with firmware, install TWRP Recovery and back up the boot partition – this will help to quickly restore the system in the event of a failure.
