When Xiaomi, Redmi or POCO stops responding to touch and doesn’t want to reboot, it causes panic in any user.The screen can burn black, show a logo or just freeze on the last open app. It is important to remain calm, since in most cases the problem lies in a software failure that can be fixed by yourself without visiting the service center.
The first thing to understand is that the device doesn't necessarily have to be physically broken, and it's often caused by a system process that's hanging. system_server, A crowded RAM cache or a conflict of a newly installed application. Before looking for a soldering iron or looking for a workshop address, you should try software methods of resuscitation, which are used in the field of resuscitation. 90% In some cases, the gadget is brought back to life.
In this article, we’ll look at all possible scenarios, from simple software lockdowns to more serious firmware issues, and learn how to perform forced reboots, enter recovery modes, and diagnose battery status even if the device’s screen is not showing signs of life.
Software freeze and forced reboot
The most common reason for refusing to restart is to completely lock the interface of the MIUI or HyperOS operating system. In this case, the touch screen stops processing the presses, and the volume buttons may not change the volume. The standard long-term retention of the power button (10 seconds) in such situations often does not work, since the software interrupter does not respond to the signal.
To solve this problem, there's a Hard Reset button method that forces the power to the logic circuits, bypassing the software commands, and you're going to need to press the on button and the volume button at the same time, hold them for a long time, sometimes it takes up to 15-20 seconds, and if the Mi logo or the recovery menu appears on the screen, then the procedure was successful.
If the first combination didn’t work, try a variation for some Redmi Note models: press the power button and the volume down button.This method is often used to enter Fastboot mode, but on some firmware versions it also initiates an emergency restart of the system, resetting temporary kernel errors.
⚠️ Warning: Do not shake the device or knock on the body during the reboot attempt.Mechanical impact can damage the display plumes or tear off the battery contacts inside the housing, turning a software failure into a physical failure.
It's important to distinguish between states: if you have a vibrating response when you press the buttons, but you don't have an image, it's a problem in the display. If the phone vibrates and makes sounds, but the screen is black, try flashing a flashlight into the matrix. If you see a dim image of the interface, then the backlight is burned, and software reboot won't help here.
Diagnostics of problems with the power button
Often, users are faced with a situation where the phone does not reboot due to a physical malfunction of the on button itself. In Xiaomi models with a side fingerprint scanner, this button is a critical node. If dust, moisture or contact has accumulated under it, the signal simply does not pass to the motherboard.
You can check the state of the button visually and tactilely. Pressing should be clear, with an audible click. If the button falls through, hits or, conversely, is clamped in the "on" position, this explains the strange behavior of the device. In some cases, the button can stick due to the entry of sweet liquid or glue from the protective case.
There is a software way to bypass a broken button if the screen is at least partially functional or the sensor is working. You can use the Double tap function to turn on the screen, and then programmatically initiate a reboot through the settings. To do this, go to Settings → Advanced Settings → Special Options → Shortcuts and set up the start of the desired action.
If the screen is completely black and the button is not working, the only option left is to connect to the charger, and some POCO and Redmi models automatically turn on when connected to the power source if the battery is not fully discharged, which can be a temporary solution to save data before going for repairs.
Enter Recovery and Fastboot Mode
If a normal reboot is not possible, try to enter special boot modes. Recovery mode allows you to reset settings, clear the cache and flash the device. Fastboot mode is used for deep diagnostics and firmware through the computer. Enter these modes when the phone is turned off (or when you try to turn it off) by pressing button combinations.
To enter Recovery Mode, press the power button and the volume button. Hold them until the Mi logo appears, then release the power button, but keep the volume until the menu appears. In this menu, the sensor does not work, the navigation is done with the volume buttons, and the selection is done with the power button.
☑️ Checking before entering Recovery
To enter Fastboot mode (often showing a hare repairing an android), a combination is used: a power button + a volume button. If the phone reacts to these combinations by vibration or changing the picture, then the motherboard is alive and the problem lies in the bootloader of the operating system or damage to system files.
You should be extremely careful in the Recovery menu. Selecting Wipe Data will delete all user data completely. If your goal is just to reanimate your phone, try first selecting Reboot or Reboot to System. If the system does not start cyclically, then only then should you consider resetting.

Problems with battery charge and power supply
Sometimes the phone doesn't reboot corny because it's got a battery down, but the charge indicator doesn't show up because of the deep discharge. Lithium-ion batteries in Xiaomi smartphones have protection that blocks turning on at critically low voltage. The device can lie on charging for hours without showing signs of life.
In the case of deep discharge, you need to use the original charger with support for fast charging Quick Charge or Power Delivery. Leave the phone on charging for at least 40-60 minutes without trying to turn it on. Sometimes you need to “rock” the battery with low currents before the power controller allows the system to start.
Check the charging connector. The USB Type-C or Micro-USB port often accumulates pocket dust and pile that compresses and keeps the cable from entering the end. Carefully, using a plastic toothpick (not metal!), clean the connector. If the cable enters with difficulty or dangles, the problem may be mechanical damage to the port.
It is also worth checking the cable and the power supply on another device. Unstable voltage can cause the phone to go into protection and not respond to buttons. Use only certified accessories, as cheap analogues often do not give the necessary current to start the system.
Failures after System Update (OTA)
One of the most unpleasant situations is to freeze after updating the firmware MIUI or HyperOS. If the battery or file was damaged during the upgrade process, the phone can go into an endless cycle of restarts (bootloop) or freeze on the logo, in which case a standard reboot will not help, since the boot partition itself is damaged.
The first thing you can try is to enter Recovery mode (as described above) and select Wipe Cache (clear cache), which is safe for your data (photos, contacts), it only deletes temporary system files, and if this does not help, you will have to go to radical measures - a complete reset of Wipe Data.
If a full reset does not work, you will need to flash the device through the computer using the Mi Flash Tool utility. To do this, you need to switch the phone to Fastboot mode. However, if the bootloader is locked, you may need a Mi Account with a certain level of access or waiting for unlock, which in a situation with a broken phone creates additional difficulties.
It’s important to note that interrupting the upgrade process is a guaranteed way to turn your smartphone into a brick that requires professional intervention.If you see the upgrade bar progress, never touch the buttons, even if the process seems to be 99% hung.
Hardware malfunctions and the brick
When all software methods are exhausted and the phone is still dead, there is a high probability of hardware failure, which can be a failure of the memory chip (eMMC or UFS), which is a common problem on older Xiaomi models.
Another common cause is a chip or processor that has collapsed due to a fall or overheating, and in these cases, the phone may be warming up in a certain place even when it's turned off, and you can't fix it yourself at home, you need to warm up on professional equipment or replace components.
If the phone falls into water, it counts for minutes. Even if it works, the contacts can corrosion at any time, in which case you can not try to charge the device or dry it with a hairdryer (hot air drives moisture deeper), the only correct action is to turn off (if possible) and carry to the service for ultrasonic cleaning.
⚠️ Warning: Do not attempt to disassemble the phone yourself if it is under warranty.Failure of seals and autopsy marks will lead to loss of warranty obligations, even if the breakdown is not related to your intervention.
If you suspect a dead memory or a burned-out power controller, further attempts to turn on can only make the situation worse, it is better to leave the device alone and consult specialists for accurate diagnosis with a multimeter and a programmer.
