Why Xiaomi is not included and what to do: the complete guide

When your beloved Xiaomi suddenly turns into a brick and refuses to respond to the power button, it can take you by surprise: the screen stays black, the indicators are silent, and it feels like the device is out of order forever. However, in most cases, the problem is not a fatal motherboard failure, but a software failure or a deep battery discharge that is easy to fix yourself.

Before you carry a gadget to the service center, it is worth conducting a basic diagnosis to rule out simple causes. Often the system freezes in a cyclical reboot or goes into deep sleep due to driver conflict or Bootloader malfunction. In this guide, we will analyze proven algorithms of actions that will help to revive the smartphone without losing data or with minimal risks.

Don't panic if the device doesn't show signs of life immediately after you connect to a charge. Modern lithium polymer batteries at critical discharge take time to "pump" low-power current. If you drop your phone or wet it, the actions will be different from the software failure, so it is important to first visually assess the condition of the case and connectors.

Primary diagnosis and elimination of nutritional problems

The most common, but common, reason is that if the smartphone was idle for several weeks, the battery voltage could drop below the start threshold of the power controller, in which case the standard indication may not work immediately. Connect the original cable and power supply, leaving the device alone for at least 30-40 minutes, even if the screen does not light up.

Notice the state of the USB Type-C or Micro-USB charging port. Pile and dust often accumulate in clothing pockets, which block contact. Carefully, using a wooden toothpick or plastic spatula (but not metal!), clean the connector. Damage to contacts inside the port can also prevent charging, which will require soldering in the service.

⚠️ Warning: Do not try to charge the ballooning battery. If the back cover of the smartphone is moved or the screen is raised, immediately stop the power supply - this can lead to a fire.

Sometimes the problem lies in the cable or the power supply itself. Try replacing the components with those that are known to be serviceable from another device. Using cheap, unstable current analogues may not "break through" the protection of the PMIC charge controller. If the phone reacts with vibration, but the screen is black, perhaps the display module, not the system itself, is defective.

Forced reboot and button combinations

If the Xiaomi phone doesn’t turn on but is showing signs of life (vibration, Mi logo), there is likely to be a failure of the Android operating system or the MIUI shell. Standard holding the power button for 10-15 seconds often solves the problem of a hung interface.

In cases where a normal reboot does not help, you need to enter special boot modes. This uses key combinations that need to be pinched simultaneously and held until the corresponding menu appears. Accuracy and timing of the presses play a crucial role here.

• 🔘 Fastboot mode: Press the volume down button ("Loudness -") and the power button at the same time. Hold until the image with the android hare appears. This mode serves to firmware the device through the PC.
• 🔄 Recovery Mode: Press the Volume Up button ("Loudness") +») You can reset or flash it without a computer.
• 🚫 Exit cycle: If the phone is hanging on the logo, try clamping all three buttons (Loudness) +, Loudness - food - at the same time 15-20 seconds.

Once in the Recovery menu, the navigation is done with volume buttons and the power button confirms the choice. If you see a menu in Chinese, don't worry: this is usually the standard recovery mode. To reset, select Wipe Data, but remember that this will delete all user files.

Diagnosis through connection to a computer

Connecting your smartphone to your computer is one of the most informative ways to diagnose a dead device. Even if the screen is black, the internal circuits can work. USB-cable to PC and open Device Manager (in Windows via Win) + X).

Note the Ports (COM and LPT) or USB Controllers section. If a device named Qualcomm HS-USB QDLoader 9008 appears on the list, it means that the phone's processor is alive, but the bootloader is damaged or missing. EDL (Emergency Download Mode) mode allows you to restore the software part through special utilities.

If the computer makes a sound of the device connecting, but does not display anything, it may be a power controller or a display plume that has burned. USB-The port, preferably directly to the motherboard, bypassing the hubs.

Resetting and Recovery through Recovery

When a software conflict blocks the system from booting, the only way out is to reset to factory settings, which is necessary if the phone turns on before the MIUI logo, but it doesn't go beyond booting. It's important to understand that Wipe Data will completely destroy your photos, contacts and applications.

To enter the recovery menu, use the combination of Volume + and Power. In the Main Menu, select Wipe Data, then confirm Wipe All Data. The process will take a few minutes. After completion, select Reboot -> Reboot to System.

⚠️ Warning: Before performing a reset, make sure you remember the password from your Mi Account. After the reset, the system will require authorization as part of the theft protection (FRP), Without a password, the phone will remain locked.

If the reset didn’t work and the phone is stuck on the logo again, the system file section may be damaged, which would require a complete flashing. For models with an unlocked bootloader, you can do this via the Connect with MIAssistant menu by connecting the phone to a computer with the Mi PC Suite installed or the Mi Flash utility installed.

💡

Useful tip: If you're afraid of losing data, try selecting Connect with MIAssistant from the Recovery menu and connecting to your PC, which sometimes allows you to copy files even if the system isn't loading.

Firmware of the device via Fastboot and Mi Flash

The radical solution to the problem of black screen or endless boot is to reinstall the operating system, USB-cable, Xiaomi Mi Flash Tool and firmware image (Fastboot) ROM) Importantly, if you have a global Chinese firmware, you can block your phone.

First, load your phone into Fastboot mode. Connect it to your PC. Launch Mi Flash, press the Refresh button, the program must identify the device. Choose the path to the folder with the unpacked firmware. At the bottom of the window, you need to choose Clean all or Clean all and lock.

The firmware process takes 200 to 600 seconds. Don't turn off the cable or touch the phone at this time. If you have a Missmatching image and device error, you've downloaded the wrong firmware for the wrong model. Once successfully completed, the phone will automatically restart, and the first download can last up to 10 minutes.

💡

Fastboot firmware is the most reliable way to revive Xiaomi, but requires an accurate selection of the version of the software. Error in choosing a region (CN/Global) can lead to locking the device (Hard Brick).

Hardware malfunctions: when you need a master

If none of the software methods worked and the phone still doesn't turn on, there's a high probability of physical failure. A common cause of death for Xiaomi is the failure of the PMIC power controller or charging circuit, which happens due to power surges, the use of substandard charges or moisture.

It's also worth checking the plumes. If you fall, you could move the display connector or the power button plume, if you connect to charging, the phone warms up in a certain area or emits a specific squeak, it's a sign of a short circuit on the board. Self-repair in such cases without soldering equipment and circuitry is impossible.

• 💧 Moisture intake: Even if the phone is dry, contact oxidation continues.Ultrasound cleaning is required in the service.
• 🔋 Battery death: The battery could have gone deep below 2.5V and the controller blocked the charge.
• 📱 CPU dump: Characteristic of some models after falls. Rebolling of the chip in SC conditions is required.

Don't try to disassemble the phone if you don't have experience, especially if it's warranty-free. Opening the case automatically voids the manufacturer's warranty obligations. You'd better go to an authorized diagnostic center.
