When a Xiaomi, Redmi or POCO smartphone screen suddenly lights up with a hare fixing a robot and the words FASTBOOT, it often takes the user by surprise. It's not a breakdown in the usual sense of the word, but a special low-level debugging mode designed for engineers and advanced users. However, accidentally hitting it can paralyze the device, making it impossible to make calls or use applications.
It's not a good time to panic, because the phone's system is completely functional, it's just waiting for a computer to run a firmware or restore a memory partition, and in most cases, it takes between a few seconds and a couple of minutes to get out of this state, if you know the right sequence of actions, and we'll go through all the possible scenarios in detail below.
Why the phone itself went to Fastboot mode
Before you can find a solution, you need to understand the cause of the problem. Most often, the activation of the mode is due to mechanical action on the device body. Volume control buttons located on the side of the face could be accidentally pinched in a pocket of tight clothes or in a case, in which case the phone perceives a prolonged press as a command to enter the engineering menu.
The second common cause is software failure or system file corruption. If you tried to install custom firmware, get root rights, or upgrade at the wrong time, the bootloader might lock up while waiting for a serviceable version of the software.
โ ๏ธ Note: If the device enters Fastboot mode on its own immediately after turning on without pressing the buttons, this may indicate a physical breakdown of the volume plume or sticking of the microbutton.
Sometimes the cause is a failed reset or an interrupted update "over the air", in which case the system can not find the boot partition and goes into emergency standby mode, understanding the cause will help you choose the right exit method and avoid a repeat of the situation in the future.

Use a protective case with high sides around the volume buttons to prevent them from accidentally clamping in your pocket.
Classic method of exiting through buttons
The easiest and fastest way to do this, which works 90 percent of the time, is to force a reboot, so you don't need a computer, cables, or any special software, but you just do certain things with the physical buttons on the body of your smartphone, and it's safe and it won't cause any data loss, because we're just initiating a reboot.
To perform the procedure, you need to pinch and hold the power button. 10-15 So, at this point, the hardware resets, and the phone starts to boot normally. If the screen goes out, but the phone shows the rabbit again, try slamming the button combination.
Alternatively, you can simultaneously press the power button and the Volume Down button. 10-15 This action emulates the battery extraction and forcibly shuts down the device. Once the screen goes out, release the buttons and wait for the Mi or Redmi logo to appear.
โ๏ธ Exit algorithm with buttons
Exit from Fastboot with a computer and ADB
If the mechanical buttons fail to respond or are damaged, software methods come to the rescue), USB-cable and installed drivers ADB (Android Debug Bridge is considered more professional and allows you to send a command to the output directly to the bootloader.
First, you need to connect the smartphone to the PC through USB-Make sure the cable is working and transmits data, not just charging the device. On your computer, open the command line or terminal in the tool folder. ADB. Enter a command to check the connection.
adb devicesIf you have a device with a serial number and fastboot status on the list, you've got the connection, and you've got to send a special command to force the phone to restart to normal mode, and you type the following line and press Enter:
fastboot rebootOnce the command is executed, the phone should restart immediately. If the command does not execute, check the installation of drivers. It may not be enough specific drivers for the bootloader mode, which can be found on the manufacturer's official website or as part of the SDK Platform-Tools platform.

What to do if the buttons are stuck or broken
This becomes more complicated if the reason for entering Fastboot mode is a physical malfunction, and a sticky volume button will constantly send a signal to the system, and the phone will return to bootloader mode immediately after trying to exit, in which case the software methods may not work or give a temporary effect.
Try tapping your finger gently on the button area to stir the mechanism. Sometimes it helps to press the button lightly at different points around the button. If you feel that the button is broken, it failed or does not press, you will need repairs. While the device is in your hands, you can try the method of massage contacts.
As a last resort, if the button closes the contacts inside the plume, you can try to gently disconnect the button plume from the motherboard, this will require removing the back cover (if it is removable) or gently opening the perimeter of the case, but this method is only suitable for experienced users who know the device of their Xiaomi.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone goes out and goes back into Fastboot | Sticky volume button | Cleaning contacts or replacing the plume |
| The computer can't see the device. | Faulty. USB-cable | Replacement of cable with a qualitative analogue |
| The fastboot reboot team is not working. | Lack of drivers | Installation of Xiaomi USB Drivers |
| The screen goes off, but the phone doesn't load. | Battery discharged | Charging in the off state 30 minutes |
Use of the Mi Flash Tool
For Xiaomi device owners, there is an official Mi Flash Tool that is often used for flashing, but can also help with diagnostics. If standard ADB commands don't work, this program may have deeper access to the device, but you should use it with caution so as not to start the firmware process accidentally.
Connect your phone in Fastboot mode to your computer and launch the Mi Flash Tool. The program must identify the device by displaying its serial number in the list. If the device is found, this confirms the port and the base loader are in good condition. Some versions of the utility have a status check or a safe exit function.
The main rule when working with the Mi Flash Tool is not to press the Flash button unless you plan to completely reinstall the system. Your goal is just to make sure that the computer "sees" the phone. Sometimes the mere fact of connecting and questioning the utility device resets the status error, and the phone can be restarted with buttons.
โ ๏ธ Note: Do not use the โClean Allโ feature in the Mi Flash Tool without unlocking the bootloader, otherwise you risk getting a completely locked device (Brick).
Specificity of Redmi and POCO models
Different smartphone lines can have their own behaviors, such as some Redmi Note models that have a software bug where the phone goes to the Fastboot when the battery is low, so you just need to charge the device for 30-40 minutes without turning it on, and then try the standard output.
POCO models, especially the F and X series, sometimes require longer button retention to exit mode. If 15 seconds don't help, try holding the power button for up to 30 seconds. Also, these devices often have a proximity sensor problem that can conflict with the bootloader, but this is rare.
It's important to note that global firmware (Global ROM) versions are standard, while Chinese versions (CN ROM) may have nuances that display language selection menus after reboot. Don't be afraid if the phone prompts you to choose a language after release - that's okay.

On models with a non-removable battery, long-term retention of the power button (up to 30 seconds) is the only safe way to reset hardware.
