Why the smartphone is stuck in Fastboot and what to do about it
Fastboot mode on Xiaomi Redmi Note 5A is an engineering mode for firmware and system recovery via PC. Normally it is activated when holding the button Volume down + Power during turn on, but sometimes the device βhangsβ in this state after a failed update, resetting or even accidentally pressing button combinations. If on the screen of your Redmi Note 5A the inscription FASTBOOT with the image of a hare in a hat-eared donβt panic: in 95% of cases, the problem can be solved without contacting the service center.
The main reasons for getting into the βeternalβ Fastboot:
- π Interrupted update MIUI β if the firmware has downloaded, but the installation has not been completed (for example, due to a discharged battery).
- π§ Improper unlocking of the bootloader β trying to use fastboot oem unlock without official permission of Xiaomi.
- π± Hardware failure β damage to buttons Volume or Power, which is why the system βthinksβ that they are clamped.
- π₯οΈ PC conflict β if you connected the phone to the computer for firmware, but drivers ADB/Fastboot wrongly.
Important: Redmi Note 5A (codenamed ugglite) has two versions - with a Snapdragon 425 processor and a Snapdragon 435. The exit methods from Fastboot are the same for both, but if you plan to reflash the device, make sure you download the correct version of MIUI!
Method 1: Forced reset (the easiest way)
If the phone is just stuck in the Fastboot, but the firmware is not damaged, a hard reboot will help, which does not delete data and works in 70% of cases.
Instructions:
- Hold the Power button for 20-30 seconds (until the screen is vibrating or turned off).
- If the screen is gone, release the button and wait 5 seconds.
- Press Power again to turn the phone on as normal.
β οΈ Attention: If Fastboot reappears after the reboot, the problem is deeper. Do not try more than 3 times: this can damage the boot partition if the cause is a hardware button failure.
βοΈ Checking before rebooting
Method 2: Exit via button combination (if sensor is working)
On the Redmi Note 5A, the touchscreen is sometimes active in Fastboot mode, allowing you to use a hidden menu to reboot.
How to check and exit:
- Touch the screen β if there is a vibration or button highlighting, the sensor works.
- Press and hold Volume up + Volume down simultaneously for 10 seconds.
- If the Recovery menu appears, select Reboot β System (use volume buttons for navigation, Power for confirmation).
π‘ If the sensor doesnβt respond but the screen is turning on, try connecting the phone to charge for 10 minutes β sometimes it βwakesβ the system.
| Symptoms. | Probable cause | Recommended method |
|---|---|---|
| Fastboot comes after the update | Boot section damaged | Method 3 (Mi Flash Tool) |
| The phone itself is included in the Fastboot | Button sticking or EMMC failure | Method 4 (testing of hardware) |
| Fastboot after unlocking the bootloader | The Wrong Fastboot Command | Method 5 (Recovery through EDL) |
Method 3: Flashing through the Mi Flash Tool (for power users)
If the phone doesn't respond to the reboot, you'll need to restore the firmware through the PC, which deletes all the data, but returns the device to working condition.
What you need:
- π₯οΈ Windows computer 7/10/11 (driver Linux/Mac harder to install).
- π Cable USB Type-C (original or high quality).
- π Fastboot firmware ROM For the Redmi Note 5A (Download from the official Xiaomi website).
- π οΈ Mi Flash Tool (version 2023.4.28.0 or later).
Step-by-step:
- Unpack the archive with the firmware in the folder C:\MiFlash\rom (the way without Cyrillic!).
- Install ADB/Fastboot drivers via Android SDK or Xiaomi Driver Installer package.
- Connect the phone to the PC, holding Volume Down + Power (should be defined as Qualcomm HS-USB QDLoader 9008).
- In the Mi Flash Tool, select the firmware folder, press Refresh, then Flash (select Clean all for full cleanup).
β οΈ Note: If the Mi Flash Tool is in error 0x80070002 or 0x8007001f, signifier:
- π« QDLoader drivers are not installed (use this package).
- π Port port USB 3.0 conflict - connect to the USB 2.0 (black PC connector).
- π The path to firmware contains gaps or Cyrillic.
What if the Mi Flash Tool can't see the phone?
Method 4: Checking the hardware (button sticking, battery)
If the phone boots on its own to Fastboot without your actions, the problem may be:
- π Battery discharge β with a charge level below 5%, the system cannot load Android.
- ποΈ Button sticking β a common problem after moisture or mechanical damage.
- π Damage to the button plume (relevant after falls or disassembly).
How to diagnose:
- Button check: Tap the buttons gently Loudness down and Power - if the phone vibrates or the screen flashes, the button is stuck.
- Battery test: Connect charging for 30 minutes. If the indicator does not burn, the battery is discharged to zero (you need to βpushβ the charger with a voltage of 5.1-5.2V).
- Visual inspection: Light a flashlight on the buttons β if you see oxidation or dirt, you will need to clean with an alcohol solution (90%+).
π‘ If the buttons are physically good, but the phone still turns on the Fastboot, try turning off autoboot in Recovery:
- Press Volume Up + Power to enter Recovery.
- Select Advanced β Disable Fastboot Auto Boot.
- Reset the device.
π‘
If the phone itself turns on in the Fastboot after a complete shutdown, there is an 80% probability of a problem in a stuck Loudness down button or a damaged plume.
