Many owners of Xiaomi, Redmi and POCO smartphones at least once faced with a situation when after a reboot the device does not turn on as usual, and the image of a rabbit repairing an android with the inscription "Fastboot" appears on the screen. This condition often causes panic, especially if the user does not understand what happened and how to return the gadget to normal work. In fact, this is not a breakdown, but a special mode of the bootloader, designed for debugging and flashing, into which the phone could get by accident or due to a system failure.
The main task at this point is not to do unnecessary actions that can make things worse, such as trying to reset the settings or disassemble the case. You can exit the Fastboot Mode on Xiaomi in several ways: from simply pressing buttons to using a computer with drivers installed. The choice of method depends on whether the touchscreen works, whether the device responds to commands and what the reason for entering this mode.
In this article, we will discuss all possible causes of the problem in detail and provide step-by-step instructions for solving it. You will learn how to safely restart the device, what to do if the buttons do not respond, and in which cases you should worry about the state of the hardware of the smartphone.
What is Fastboot Mode and Why It Engaged
Fastboot is a debugging protocol built into an Android bootloader that allows a user or engineer to interact with the device's file system directly through a computer. On Xiaomi smartphones, this mode is used to install custom recavators, flash the system, unlock the bootloader or reset forgotten passwords. Unlike the normal mode, the operating system does not boot fully, which gives access to low-level commands.
Getting into this mode is often accidental, and the most common reason is the simultaneous clamping of the power buttons and reducing the volume when removing the phone from your pocket or bag. Mechanical impact on the buttons at the time of on or restart almost guaranteed to put the device in debugging mode, also the cause can be a failure in the work of system files, a failed software update or connection to a computer with certain parameters. USB-debugging.
⚠️ Warning: Being in Fastboot mode doesn't erase your data, but while the phone is in that state, you can't make calls, use apps or use the camera.
Sometimes the user initiates the login to Fastboot via the developer menu or special ones. ADB-If you haven't done this, and the phone has fallen into this mode on its own, it's worth checking the state of the volume buttons. Sticking a mechanical button is a common cause of cycling logging into the bootloader menu every time you try to turn on.
Technical details of the Fastboot mode
Method 1: Forced button reboot
The simplest and safest method, which works 90 percent of the time, is to perform a hard reset, which doesn't delete your photos, contacts or apps, it just forcefully shuts down and re-engages the device, ignoring the current state of the hanging processes, and you don't need any additional tools or computer to do this.
You need to press the power button and hold it for a long time. On different Xiaomi and Redmi models, the retention time can vary from 10 to 20 seconds. The screen should go out, after which the Mi or Redmi logo will appear, and the phone will start loading in normal mode. If just holding the power button didn't help, try the button combination.
☑️ Algorithm of actions for exiting buttons
If the standard power button hold fails, use a key combination. Press both the power button and the Volume Up button. Hold them for about 10-15 seconds. This combination is often used to exit the receiver, but it can also work to exit the Fastboot if the system does not respond to a single press.
⚠️ Warning: Don't confuse the buttons" +"Volume Down is what Fastboot mode is about. If you hold them too long after you reboot, the phone will go back into debugging mode.
Method 2: Using a computer command (ADB)
If the mechanical buttons do not respond or the smartphone cyclically returns to Fastboot mode, you can use the software output method through a computer. USB-cable and installed drivers ADB And Fastboot, which is considered more reliable in software failures.
First, download and install the minimum Platform-tools toolkit from the official Android developer site. Once you unpack the archive, open the command prompt (CMD) in the tool folder. Connect the phone to your computer with a cable. Make sure that the Device Manager defines the phone as Android Bootloader Interface.
Enter the following command in the command line to check the connection:
fastboot devicesIf you see the serial number of the device, you've got a link.
fastboot rebootAfter pressing Enter, the phone should restart immediately.If the command is not executed, check integrity USB-Or try another cable port. USB, preferably USB 2.0.
💡
Use of the ADB-commands are the cleanest way to exit, as it does not depend on the state of physical buttons and allows you to diagnose a connection with the bootloader.
Method 3: Method of battery discharge
When software methods are unavailable and buttons do not respond because the power controller freezes, the last, albeit longest, option is to completely discharge the battery, a method that relies on the fact that at a critically low battery charge, the device will forcefully shut down, and on subsequent connection to charging, it often starts in normal mode, bypassing the Fastboot.
Leave your phone in Fastboot mode until the screen goes out and the device shuts down completely. This can take anywhere from hours to days depending on the residual charge. Once the phone is out, plug in the original charger. Without pressing any buttons, wait for the charge indicator or logo to appear.
If, after connecting to charge, the phone again shows the Fastboot rabbit, quickly (within 2-3 seconds) press and release the power button several times. Sometimes this helps to "catch" the moment of on and interrupt the automatic debugging mode. If this does not help, leave the phone on charging for 30-60 minutes, then try the combination "Power" + "Loudness up" to enter Recovery, and from there select Reboot to system.
Causes of cyclical login to Fastboot
If, after a successful reboot, the phone goes into Fastboot mode again and again, it indicates a more serious problem. Most often the culprit is a stuck or damaged volume button. When turned on, the system polls the state of the buttons, and if "Volume Down" is closed, the bootloader perceives this as a command to enter firmware mode, which often happens after the phone falls or moisture hits.
The second common cause is damage to the boot boot system files or partition, which can occur after a software update fails, the flashing process is interrupted, or the root system files are tampered with, in which case it is impossible to boot properly and the phone goes into safe debugging mode.
The third is a failure of the plume or motherboard, and oxidation of the contacts or the failure of the button plume can give a false signal, and problems can also be caused by a poor battery that can not produce the necessary current to start the system, dropping the phone into low power or debugging modes.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The phone goes into Fastboot on its own. | Volume button sticking | Careful button development or plume replacement |
| The fastboot reboot team is not working. | Damage to the loader | Flashing through the Mi Flash Tool |
| The screen is flashing, but the loading is not going | Software failure or update conflict | Reset to factory settings (Wipe Data) |
| The phone only responds to charging. | Deep discharge or death of the AKB | Long-term battery charging or replacement |
What to do if nothing helps
In situations where none of the software methods did not allow to bring the Xiaomi smartphone out of Fastboot mode, and mechanical impact on the buttons does not work, we are most likely talking about a hardware problem.
It is recommended to contact an authorized service center for diagnostics, specialists will be able to determine exactly whether the cause of the button, plume, battery or motherboard, in some cases, you need to solder components or replace modules, which can not be done at home without special equipment.
⚠️ Warning: If the phone fell into the water before the problem occurred, do not attempt to charge it or connect it to the computer. moisture inside the case can cause a short circuit. Put the device in a dry place and bring it to the service.
For experienced users who are confident, there is a way to temporarily shut down the button plume, which is to gently open the back cover (preheat the perimeter) and disconnect the volume button plume from the motherboard. Then try turning the phone on with the power button. If the device is booting, the problem is the buttons. However, this method requires skills and tools.

If you plan to carry your phone for repair, be sure to remove it. SIM-card and memory card, if any, to save data and prevent damage during diagnosis.
