Exit from Fastboot Xiaomi without the power button

The Xiaomi smartphone’s Fastboot mode is often a nasty surprise to the user.The screen lights up, but instead of the usual Android download, you see an image of a rabbit fixing a robot or the inscription “Fastboot”. The situation is made worse if the physical on button, which is commonly used to exit this state, has stopped responding or is broken. POCO Know that a standard button combination may not be available.

Fortunately, there are alternative ways to bring the gadget back to life. The engineering mode allows you to perform low-level operations with the firmware, but sometimes it is activated accidentally due to button sticking or software failures. In this guide, we will look at methods that do not require the use of a damaged Power button. You do not need to be an experienced engineer to cope with the task.

Before you start manipulating, you have to understand the nature of the problem, and if the device is stuck in this mode, then the system can't find the bootloader or user data to start. Forced reboot is the first thing that comes to mind, but if the power button is not working, you have to look for workarounds, and we'll study software utilities and physical methods of exposure.

Reasons for freezing in Fastboot mode

Understanding the cause of the freeze helps you choose the right recovery method. Often the problem is mechanical damage to the case. If you drop your phone, the volume button could get inside. Because the input to Fastboot Mode is by pressing the volume button when you connect to USB, the sticky key constantly sends a signal to start this mode.

Another common cause is software experiments that fail: Trying to install custom TWRP recovery or reflashing the device over a Fastboot with an interrupted connection can result in a cyclical reboot, in which case the phone simply cannot move to the next boot step and remains waiting for commands.

⚠️ Note: If your phone has been flooded with water, trying to connect it to your computer or charge it may result in a short circuit.In such cases, first make sure the device is completely dry.

Also worth mentioning are software conflicts: Updating a MIUI or HyperOS system sometimes contains errors that violate the integrity of the boot partition, resulting in the device getting stuck during the check phase of the system files, and in rare cases, a faulty battery is the culprit, which cannot produce the necessary current to fully start the system.

Software output via ADB and computer

The safest and most efficient way to do this is to use the Android Debug Bridge (ADB) debugging interface, which requires connecting your smartphone to your computer. You'll need a USB cable and installed drivers for Xiaomi. The computer needs to recognize the device as the Android Bootloader Interface.

To start, download the Platform Tools package from the official Android developer site. Unpack the archive into a convenient folder. Open the command prompt (cmd) in this directory. If USB debugging was enabled before you got to Fastboot, you can control the phone directly. Type a command to check the connection:

adb devices

If the device appears in the list, you can try sending a command to restart. However, in Fastboot mode, standard ADB commands may not work, so the fastboot utility is often used.

fastboot reboot

This command forces the signal to reboot, ignoring the state of the physical buttons. The phone has to go out of mode and try to boot the operating system. If the screen goes out and the MI logo appears, then the method worked. In some cases, you need to repeat the command several times at intervals of 2-3 seconds.

Use of the Mi Flash Tool

The official tool from the manufacturer, the Mi Flash Tool, can also help in this situation, and it's designed to flash it, but it has a simple reboot function, download the latest version of the utility from the official website and install it on a Windows PC.

Connect your smartphone in Fastboot mode to your computer. Run the Mi Flash Tool. If the drivers are installed correctly, a number and letter code will appear at the top of the window in the device address field. That means that the connection to the bootloader is established. You don't have to choose a firmware file unless you plan to reinstall the system.

In the program interface, find the Refresh button. Press it to update the list of connected devices. Once you make sure your phone is displayed, look at the bottom control panel. There should be a Reboot button. Pressing it initiates a programmatic exit from mode, which is especially useful when standard commands through the CMD do not work.

Method of full discharge of the battery

If you don't have a computer on hand or if you're having trouble installing drivers, the easiest, if long, way is to completely discharge. The essence of the method is to wait until the smartphone battery runs out completely. The Fastboot mode consumes energy, and after a few hours or even a day the phone will turn off.

After the screen has gone out and the device has stopped responding to any action, leave it to lie down for another 30-60 minutes, which is necessary to stabilize the battery chemistry. Then plug in the original charger. Most Xiaomi smartphones, when connected to a fully discharged battery, start charging, but do not automatically turn on.

When the charge reaches about 10-15%, try pressing the power button. If it doesn't work, the phone can turn on itself when a certain charge threshold is reached, or it will require a short circuit of the contacts (about what is below), this method is guaranteed to reset temporary memory errors, since when completely shut down, the RAM is cleared.

⚠️ Warning: Do not leave a discharged lithium polymer battery in a deep discharge state for weeks, which can cause permanent damage and bloating.

Hardware discharge through contact closure

For advanced users who don't have an on button, there's a method of closing test points on the board, which requires disassembling the device and having a thin tweezer or needle. Be careful: sloppy movement can damage the motherboard.

You need to remove the back cover and battery (if it's not removable, gently unplug the battery plume from the board).Look for contacts on the motherboard signed as "Test Point" or just two little golden dots next to the processor. By closing them with a metal object and simultaneously connecting them USB-cable to PC, you will put the phone in mode EDL (Emergency Download Mode).

In EDL mode, the device is defined by the computer as "Qualcomm HS-USB QDLoader 9008." This is a simpler state to get out of: just turn off the cable and wait, or use specialized software for the reboot command. This is an extreme measure when other methods are powerless.

💡

Use a plastic shoulder blade or toothpick with coiled foil to close the contacts to minimize the risk of static discharge, which is more dangerous to electronics than short circuit.

What to do if the power button is physically broken

If you've exited the Fastboot and the Power button never worked, you've got to solve the problem of controlling your phone, and it's not easy to turn the device on every time you use your computer. Android has a "Planned On and Off" feature, and you can set up an automatic turn on every morning at 7:00.

It is also worth considering the use of external triggers for games, which can be adapted to the volume buttons, if the problem is in sticking.To fully repair will require replacing the button plume or charging module (on some models, the power button is located on the plume of the charging port).

A temporary solution may be to use accessibility features, some models allow you to control the screen through voice commands or gestures, but to get out of the off state without the power button, you will have to rely on automation or connection to the charger, if this feature is supported by your version of MIUI.

💡

If software methods and discharging don’t help, the problem is almost certainly a physical malfunction of the button plume or the motherboard itself.
