You pressed the power button, but Xiaomi's screen was black -- no logo, no vibration, no boot sound? -- The situation is familiar to many owners of Redmi, POCO or Mi smartphones, especially after falls, battery discharge to zero or failed updates. In 80% of cases, the device can be brought back to life without visiting a service center, the main thing is to act systematically.
This article is not about shamanism with "shaking the phone" or "knocking the body." We'll look at technically sound methods, from basic charging checks to flashing through the phone. EDL-The mode used by Xiaomi engineers, each method tested on models 2020-2026 (including the Redmi Note 12, POCO X5, Important: If the phone is in water or has been physically damaged, some methods may make the problem worse β read the warnings in each section.
Let's start with the simplest and gradually move on to the most complex manipulations, USB-cable (preferably original) and 10-15 minutes of time.
1. Diagnostics: Why Xiaomi is not included?
Before you try to "resuscitate" your smartphone, identify the possible cause of the malfunction, which will save time and eliminate the risk of additional damage.
- π No response to charging (indicator does not burn, phone does not warm up) β Problems with battery, power controller or cable.
- π± There is a vibration/light button, but the screen is black. β damage to the display plume or graphics chip.
- π The phone is rebooted in a loop (the Xiaomi logo appears and turns off) β Firmware failure or damage to the boot partition.
- π§ Liquid intake (even if everything is dry on the outside) β corrosion of contacts on the board, disassembly is required.
- β‘ Strike or fall β possible microcracks on the board, the dump of memory chips.
If the phone is dead and shows no signs of life after connecting to charging, do not rush to panic. Modern Xiaomi smartphones (starting with the Redmi Note 8) have deep-discharge protection: the controller blocks the power supply if the battery voltage fell below 3.2V. In this case, you will need to force recharging - about this in the next section.
2.Rigid reboot: a universal way for all models
The first thing you need to do is to do a hard reset, which works even if the phone is completely stuck on the black screen or doesn't respond to the buttons, and the key combinations vary depending on the model.
| Series of devices | Button combination | Retention time |
|---|---|---|
| Redmi Note 10/11/12, POCO X3/X4/X5 | Food + Volume up | 10-15 seconds |
| Mi 11/12/13, Mi Mix | Food + Volume Down | 8-12 seconds |
| Redmi 9/9A/9C, POCO M3/M4 | Food + Volume up + Volume down | 20 seconds |
| Black Shark (Gaming Smartphones) | Power + Shark button | 15 seconds. |
Algorithm of action:
- Connect your phone to charging (even if it doesnβt show signs of charging).
- Press the button combination and hold until the Xiaomi logo or vibration appears.
- If the screen is black, try again with a different combination (for example, for the Redmi Note 10 try Power + Volume down).
β οΈ Note: Do not use metal objects (clips, needles) to press buttons - this can damage the contacts. If the power button is stuck or does not press, go to the section about charging without turning on.
βοΈ Preparing for a hard reset
3. Forced charging: if the battery is completely discharged
If the smartphone is down to 0% and does not respond to the connection to the network, the power controller can block charging, in which case the method of βtriple chargingβ, which deceives the system and starts the process of restoring the voltage, will help:
- Connect the phone to the original charger (at least 18W).
- Hold the power button for 30 seconds (even if there is no reaction).
- Without releasing the power button, connect your phone to your computer via USB (use the rear USB 3.0 port on your PC).
- Hold the combination for another 20 seconds, then let go.
- Leave your phone on charge for 1-2 hours β even if there is no indication, the battery can slowly recover.
To speed up the process, an external power source can be used:
- π Power Bank with Trikle Charge (e.g. Xiaomi Mi Power Bank 3).
- π§ Laboratory power supply (if you have experience with electronics) 4.5V battery-contact.
- π Another smartphone in mode OTG (Special cable required).
β οΈ Warning: If after 2 hours of charging the phone remains cold (not warmed even slightly), the power controller is likely to malfunction (PMIC). In this case, repairs will be required at the service center.
Why canβt you charge a discharged Xiaomi from a laptop?
4.Fastboot Mode: Recovery via PC
If a hard reboot didnβt help, but the phone does react to a connection to a computer (defined as an unknown device), try entering Fastboot mode. This is a low-level mode that allows you to reflash a smartphone even with a damaged operating system.
Instructions for Windows:
- Install Xiaomi drivers: Download the Mi Flash Tool (official tool). Connect your phone to your PC when it's off. In Device Manager, find "Unknown device" β manually update the driver by specifying the folder with MiFlash.
Food + Volume Down
10 seconds.

fastboot devicesIf the serial number of the device appears in the response, the connection is established.
fastboot rebootIf the phone is not detected in Fastboot but is responsive to the connection (e.g., a USB connection sound), try an alternative sign-in method:
- π Connect the charger.
- π± Hold the Loud up. + Volume down and, without letting go, connect the cable to the PC.
- π₯οΈ Hold the buttons for another 15 seconds β sometimes it works on stubborn devices.
π‘
If fastboot devices return an empty list, try another one. USB-cable (preferably original) or port USB 2.0 on PC β some Xiaomi models are not recognized by the USB 3.0.
EDL mode: a last resort for "bricks"
If the smartphone is not powered on, charged, or detected in Fastboot, the last chance is Emergency Download Mode (EDL), which allows you to flash the phone at the processor level even if the memory or bootloader is damaged.
- π₯οΈ Windows computer 7/10/11.
- π Cable USB Type-C (preferably with screening).
- π οΈ Mi Flash Pro or QFil (for Qualcomm devices).
- π Firmware for your model (download only from official sources).
Step-by-step:
- Turn off your phone (if it is in a reboot cycle, wait for the full discharge).
- Press Volume up + Volume down and connect the cable to the PC.
- The device manager should have a Qualcomm HS-USB QDLoader 9008 (for Snapdragon) or Mediatek Preloader (for Helio/Density).
- Install the driver for EDL (can be found in the archive with the Mi Flash Tool).
- Open Mi Flash Pro, select firmware and press Flash.
β οΈ Attention: Firmware through EDL It resets all data on the phone, including accounts and files in internal memory. If the device was enabled Mi Account with an account link, after firmware may need to unlock (login / password required).
For devices running Mediatek processors (e.g., Redmi) 9A, POCO C31) Instead of Mi Flash, use it. SP Flash Tool.Algorithm is similar, but requires a separate Mediatek driver DA USB VCOM.

6. Hardware malfunctions: when to carry in the service
If none of the software methods worked, the problem is probably hardware, and here are some signs that self-repair is impractical:
- π₯ The phone warms up when charging, but does not turn on β circuit.
- π¦ Under the screen, you can see divorces or condensation. β corrosion.
- π There is sound/vibration, but the screen is black. β plume-damage.
- β‘ The phone is switched on only from charging, but immediately switches off. β malfunction of the battery or power controller.
The cost of repairs in the service center Xiaomi (in Russia, 2026):
| Type of malfunction | Cost (β½) | Duration of repairs |
|---|---|---|
| Battery replacement | 1 500 β 3 000 | 1 day |
| Repair after liquid hit (cleaning board) | 3 000 β 8 000 | 2-3 days |
| Replacement of the display module | 4 000 β 12 000 | 1-2 days |
| Recovery after a failed firmware | 2 000 β 5 000 | 1 day |
If the phone is warranty, do not disassemble it yourself - this will void warranty obligations. To check the status of the warranty, type IMEI on the Mi Verify website.
7 Prevention: How to avoid recurring problems
To minimize the risk of Xiaomi re-filling, follow these rules:
- π Do not discharge your phone to 0% β connect to charging at 15-20%.
- π Update your firmware only over Wi-Fi (not mobile data) and at least 50 times charge%.
- π‘οΈ Turn off automatic update installation in settings (Settings) β The phone. β Updating the system β βοΈ β Auto-update).
- πΎ Make backups regularly through Settings β Additionally. β Backup.
- π Use only original cables and power supplies β cheap analogues can damage the charging controller.
For owners of devices with an unlocked bootloader:
- Install only proven custom firmware (e.g. Xiaomi.eu or LineageOS).
- Check the hash sums of files (MD5 or SHA-1) before you run the firmware.
- Do not change the modem, boot, and dtbo sections without a backup.
