The situation when instead of the usual boot screen Xiaomi Redmi 6 shows an image with a hare repairing an android, or the inscription "Fastboot", can cause panic in the inexperienced user. However, this mode (bootloader mode) is a standard feature of the device designed for low-level control of the system, and in 90% of cases, exit from it does not require complex intervention of specialists.
Most often, the transition to Fastboot mode is due to accidental clamping of the volume buttons when you turn on or a failure during the firmware update process. The system may have incorrectly terminated work, and the next start automatically activated this mode for diagnosis. It is important to understand that your data is safe at this point, unless you start forced memory cleanup.
In this guide, we will look at all possible scenarios, from a simple restart to a complete flash through your computer, learn how to distinguish a software failure from a hardware button failure, and what actions to take depending on the device’s response to commands.
What is Fastboot Mode on Xiaomi and Why You Need It
Fastboot is an Android debugging protocol developed by Google that allows the user to transfer data directly to the device’s flash memory. On Xiaomi smartphones, including the Redmi 6 model, this mode is used to set factory images, unlock the bootloader or restore the system after critical errors.
Unlike Recovery, which allows you to reset or update "over the air", Fastboot works at a deeper level. It bypasses the main operating system. Which is why the screen can burn but not respond to touch, and in the corner often displays the FASTBOOT logo in orange or blue.
- 🔧 The mode is used for deep diagnostics of smartphone hardware.
- 💾 Through it, it is possible to record partitions of the system, which is necessary when flashing.
- 🔓 Without access to Fastboot, it is impossible to unlock the bootloader for installing custom firmware.
⚠️ Warning: Fastboot is safe for hardware, but trying to record a damaged or incompatible system image can turn your phone into a brick".
On Redmi 6, this mode is activated by a keyboard combination, which often causes random login, and if you put your phone in your pocket with the buttons pressed heavily, the device could have switched to this mode on its own when you discharge or reboot.
The main reasons for the Redmi 6 hit the Fastboot
Understanding the cause of the failure helps you choose the right recovery method. The most common reason is mechanical impact. The Volume Down button on Redmi 6 is located on the side of the face and can stick due to moisture, dust or wear of the membrane.
The second common scenario is a failed update. OTA-update (via Wi-Fi) there was a power surge or failure of the file system, the phone can not boot the OS and goes into emergency mode. ADB.
Sometimes the problem lies in the software conflict of installed applications that have access to system settings. Viral software or erroneous scripts can initiate a reboot in Bootloader.
- 📉 Sticking the physical volume button "Down".
- 📲 Update failure MIUI or damage to system files.
- 🦠 Influence of malware or incorrect system modifications.
If the phone has recently been hit, it's worth checking the button plumes. The internal displacement of the plume can close the contact, simulating constant pressing.
The easiest way: exit through reboot
In most cases, if the hardware is fine, Redmi 6 can be removed from the Fastboot state by a simple forced reboot, which does not require a connection to a computer and works if the power button is functioning correctly.
You need to press the Power button and hold it for a long time, usually in 10 to 20 seconds, and the screen goes out, and the device starts the standard procedure for downloading the Mi logo.
If conventional holding doesn't work, try the combination: press the power button and Volume Up at the same time. Hold them until the vibration or logo appears. This method often works better, as the system prioritizes the "up" combination when exiting debugging mode.
💡
If the phone vibrates but the screen remains black, wait about a minute - sometimes the process of exiting a Fastboot takes longer than a normal boot.
It is worth noting that if after releasing the buttons, the phone returns to the screen of the hare again, then the problem is not solved software, and the volume down button is probably physically closed.
Exit from Fastboot via computer and ADB
If the buttons on the Xiaomi Redmi 6 body do not respond or the phone returns to bootloader mode cyclically, you will need the help of a PC (ADB And Fastboot. You're gonna need it. USB-cable and installed device drivers.
First, connect your smartphone to your computer. In Windows Device Manager, a device called the Android Bootloader Interface should appear in the USB Controllers section. If there is an unknown device, install Xiaomi drivers.
Open the Command Prompt (CMD) in the ADB tool folder. Enter the command to check the connection:
fastboot devicesIf you see the serial number of the device, the connection is established. Now enter the command for forced reboot:
fastboot rebootThe phone should immediately restart in normal mode. If the command is not executed, it is possible that the drivers are installed incorrectly or the cable is damaged.
| Team team. | Description of action | The result |
|---|---|---|
| fastboot devices | Connection check | Derivation of the serial number |
| fastboot reboot | Soft reset | Access to Android |
| fastboot reboot-bootloader | Restart the loader | Re-entry to Fastboot |
| fastboot oem unlock | Unlocking BL | Data reset and unlock |
⚠️ Note: Do not use fastboot oem unlock unless you plan to officially unlock the bootloader.This action will irreversibly delete all data from the phone.
Redmi 6 firmware with Mi Flash Tool
When simple methods fail and the system is damaged, the only way out is to completely reflash. Redmi 6 (codename: ros) requires you to download the official firmware in Fastboot format (archive.tgz, not.zip).
If the Bootloader is blocked, the Mi Flash Tool will give an error, in which case you first need to get permission through the Mi Unlock site and wait 168 hours (7 days).
Procedure:
- Unpack the firmware archive in the root of the C disk (the path should not contain Cyrillic).
- Run the Mi Flash Tool on behalf of the administrator.
- Press the “Refresh” button and select your device.
- In the lower corner, select the "Clean all" mode or "Save user data" mode (save data if the version of the software matches).
- Press Flash and wait until the process is over.
☑️ Firmware preparation
During firmware, the phone may reboot several times, and do not turn off the cable until the program has the status of "success" green.
