A situation where your favorite smartphone suddenly stops responding to presses and the screen remains black can catch any owner by surprise. You should not panic at this moment, since in most cases the problem lies not in a fatal iron breakage, but in a software failure or deep battery discharge. Modern Xiaomi and Redmi devices have a complex protection system that sometimes blocks the onset under certain conditions.
Before you bring your device to the service center, you need to try to diagnose the cause yourself and apply basic methods of resuscitation. Often, a simple reboot or change of the charger is enough to make the smartphone come alive again. In this article, we will discuss in detail all possible scenarios, from the banal discharge of the battery to the need to flash through the computer.
It's important to understand that the sequence of actions depends on what exactly preceded the breakdown: a fall, moisture or just updating the system. If after a fall or water hit, the phone stopped turning on, self-charging attempts can lead to a short circuit - in such cases, it is better to contact specialists immediately. However, if there is no visible damage, you can proceed to more active actions.
Primary diagnostics and verification of food elements
The first thing to do is to rule out the most trivial, but often ignored, option, which is the full battery drain. If you haven't used your gadget for a long time or left it on in the cold, the lithium-ion battery could go into a deep discharge, in which case the charge indicator may not light up immediately, and the screen remains black even when connected to the network.
You need to leave the device on charge for at least 30 to 60 minutes without trying to turn it on. Use only the original cable and fast-charging power supply, as the power controller may not accept current from weak sources. If the screen is still not on fire after an hour, try gently moving the cable in the connector to exclude oxidation of the contacts.
Also, you should carefully inspect the charging connector for pile or dust, which often fill your pockets. Carefully clean it with a dry toothbrush or a wooden toothpick, trying not to damage the central contacts. Sometimes it is the dirt that interferes with contact, and after cleaning the phone begins to charge.

Just now / today / yesterday / not used in a long time
If you have the opportunity, try replacing the charger with a known serviceable one from another device with a similar USB Type-C or Micro-USB connector. This will help you understand whether the problem lies in the power supply itself or the cable. Often users mistakenly sin on the phone when a cheap wire just burned.
Forced reset and static voltage reset
One of the most common causes of system freeze is a software failure in which the Android operating system or MIUI shell stops responding to commands, in which case the screen may be black, but the phone is actually on and consuming power. The solution is a hardware reset known as Hard Reset buttons.
To do this, you need to press the power button and hold it for 10 to 15 seconds. If that doesn't work, try the combination: hold the volume button and the power button at the same time. Hold them until the Mi logo or vibration appears, and this method allows you to reset the residual voltage from the motherboard and force the bootloader to start.
In some models, especially those with non-removable batteries, the “battery simulation” method helps, by plugging the phone into the charger, waiting a few minutes, then quickly turning off the cable and immediately trying to turn the device on. Repeating the power connection-off cycle sometimes “wakes up” the charge controller.
⚠️ Warning: Do not try to disassemble the phone and turn off the battery plume if you do not have experience and special tools.You can damage the plume or break the tightness of the case, which will lead to loss of warranty.
Enter Recovery and Fastboot Mode
If standard on-boarding methods don't work, it's worth checking if the device responds to low-level commands, and there are special modes for this: Recovery (recovery mode) and Fastboot (loader mode), which are entered when the phone is turned off by clamping certain key combinations.
To get into the Recovery menu, you usually need to press the power button and the volume button. If the phone vibrates and shows a menu with several points (often in English or Chinese), then the display and touchscreen are good, and the problem lies in the software part.
What to do if the Recovery menu is in Chinese?
If you're on the Recovery menu, but all the items are written in hieroglyphics, don't panic. Usually the Reboot button is second on top. If you're not sure, you'd better take a picture of the screen and use a picture translator to avoid accidentally resetting the data. Fastboot mode is called by pressing the power button and volume down button. If an image with the Fastboot logo and an and a hare repairing an android appears on the screen, it's a good sign. This means that the bootloader is functioning and you can try to reflash the phone through the computer using the Flash Tool.

Before you start, make sure you understand the consequences: photos, contacts and apps will be deleted. In the Recovery menu, the navigation is done with volume buttons (up-down), and the choice is confirmed by the power button. You need to find Wipe Data or Clear Data. MIUI This menu can be in English. Select the Wipe All Data option and confirm the action. After the cleaning process is completed, which can take a few minutes, select Reboot -> Reboot to System. The first run after the reset will be long, can take up to 10 minutes. If the phone successfully boots and welcomes you to the choice of language, then the problem was in the software conflict. ⚠️ Warning: If after the data reset, the phone again hangs on the logo or goes into a reboot, the problem is most likely hardware. It could be a flash memory or a processor malfunction, and software methods are already powerless.Mi Flash Tool: When the software failure is too deep and the phone can't boot even after a reset, flashing comes to the rescue. For this you will need a computer with Windows OS, USB-You can download the firmware from miui.com by selecting either Recovery or Fastboot. To install the firmware, download and install the Mi Flash Tool. Put the phone to Fastboot mode (pressing the power and volume down) and connect it to your PC.

Save User Data mode in case the phone does not turn on, it is better not to use, as it can save an error. 5–10 minutes, it is absolutely impossible to interrupt it. 💡Successful Fastboot Flashing Eliminates 90% software errors associated with damage to system files, but requires stable USB-a battery and a battery charger (at least on the 30-40%). Hardware problems and deep recovery (EDL) If the phone does not respond to any buttons, the screen is black, but when you connect to the computer, the connection sound is heard. USB-The device may be in the mode of EDL (Emergency Download.In Device Manager, this is displayed as Qualcomm. HS-USB QDLoader 9008. This is an emergency firmware mode that often requires an authorized Mi Account to run. It can be programmatically (ADB commands) or hardwarely (disassembling the phone and closing test points on the board). If the phone has gone into this mode on its own, it often indicates a critical bootloader error or damage to memory sections. It can be difficult to log out of it without special equipment or an authorized service center account. It is also worth considering the option of mechanical damage. If the phone fell, the display plume or battery connector could go away. In such cases, the phone can be malfunctioning or the phone's screen, but the phone can be buzzed, but the phone is not be used to make a malfunctioning sound from the screen. ⚠️ Attention: Attempts to disassemble the phone and close contacts on the board for entering mode EDL This can cause permanent damage to electronics, only if you're confident in your skills and your phone is no longer guaranteed (FAQ) Xiaomi's phone vibrates, but the screen is black. What to do? It's probably the problem with the display or its plume. Try bright lighting on the screen flashlight (if there's an indication) or connect the phone to your computer. If the PC makes a connection sound, but there's no image, you'll need to change the display or solder the service plume. Can you recover data if the phone doesn't turn on? If the phone doesn't turn on and doesn't enter Recovery or Fastboot mode, it's almost impossible to recover data on your own. If you can enter Recovery mode, but you can not reset, the data may be lost when you try flashing. When critical memory failures are not restored. How long does it take to charge a fully discharged Xiaomi? When the phone is in deep discharge, it can take 30 minutes to 2 hours to charge before you first try to turn on. The indicator may not burn the first 10-15 minutes - this is normal for modern power controllers. The phone is getting stuck on the Mi logo, how to get out? You need to perform a forced reboot (press the power button for 10-15 seconds). If this does not help, try to enter Recovery mode and make a data reset (Wipe Data), after making sure that the phone turns off when charging 20%? This is a sign of battery failure, then the battery is suddenly lost from the battery.
