Your Xiaomi suddenly stopped turning on, stuck on the logo MI Or is it constantly rebooting in a cycle? This problem is familiar to many owners of the brand's smartphones - from budget Redmi to flagship Xiaomi. 13/14. The reasons can be both software (firmware failure, viruses) and hardware (damaged battery, departed contacts). 90% In cases, the device can be returned to life on its own - without contacting the service center.
In this article, we will analyze all possible scenarios: from simple solutions (forced reboot, reset via Recovery) to complex ones (flashing through Fastboot or repairing the board). 10/11), And you'll find some unique tips for diagnosing a malfunction without disassembling your phone, which will save you time and money.
Before you start repairing, answer two key questions: 1. Does the phone respond to charging (lights, vibrates when the cable is connected)? 2. Did you install updates, route the device or drop it before the failure?
The answers depend on where to start the recovery.
1. Causes of Xiaomi's cyclical reboot
Why can Xiaomi get stuck in a bootloop or not turn on at all? The reasons are divided into software and hardware. The former are more common and usually solved without disassembling the device.
Top.-5 programmatic causes:
- 🔄 Update failure MIUI — interruption OTA or recovery.
- 🦠 Virus software – some Trojans block the system from booting (often after installation) APK unverified).
- 🔧 Root: Errors in obtaining superuser rights through Magisk or SuperSU.
- 🗑️ Damage to system files – for example, after cleaning the cache through TWRP deletion.
- 🔋 Deep battery discharge – if the phone is discharged to 0% and lay for a long time without recharging.
Hardware causes are less common but require repair: A battery plume that has gone away, a damaged motherboard (especially after falls or moisture), a faulty memory module (eMMC or a slug). UFS). For example, in the Redmi Note 8 Pro often fails the power controller MT6358, which leads to the impossibility of inclusion.
How to distinguish a software failure from a hardware one? Do a reaction test: Connect charging → Press and hold the power button for 20-30 seconds.
If the phone vibrates or the light goes on, it's more of a software problem, and if there's no response, it could be a circuit board or battery that's damaged.

2. Forced reboot and reset via Recovery
The first step in any crash is a hard reset, which helps if the phone is stuck on the logo. MI or in a reboot cycle due to a temporary failure.
Instructions for all Xiaomi models:
- Turn off the phone from charging (if connected).

Check the battery power (minimum 30%)
Prepare Mi-account data (login and password)
Download the latest firmware (in case the reset doesn't help)
-->
3. Fastboot flashing (if Recovery doesn't help)
If resetting via Recovery doesn't solve the problem, the next step is to flash it over Fastboot.This method is suitable for phones that:
- 🔄 Stuck on the logo. MI or in a reboot cycle;
- 🚫 Not loaded into Recovery;
- 🔧 Have a damaged firmware (for example, after a failed update).
What you need: Windows Computer, USB-cable (original), Mi Flash Tool, firmware for your model.
Step-by-step:
- Download the firmware for your model from the official Xiaomi website (choose the Fastboot version, not Recovery).
- Install drivers: download Mi Flash Tool and drivers for Fastboot from the Xiaomi website.
- Start your phone in Fastboot mode: Turn off your phone → press the power button + volume down until the hare appears in the hat-ushanka (logo Fastboot).
- Connect your phone to your PC and check that it is defined in Device Manager as Android Bootloader Interface.
- Run the Mi Flash Tool, select the downloaded firmware and press Flash. The process will take 5-10 minutes.
⚠️ Note: On new models (Xiaomi) 12/13/14, Redmi Note 12) Before you run through Fastboot, you need to unlock the bootloader through the official Mi Unlock tool. Without this, the firmware will end in error. Also note that unlocking resets all data and requires Mi-account binding!

| POCO F3/F4 | Yes. | You can sew it through EDL (emergency) |
| Redmi 9A/9C | No. | Firmware is possible without unlocking |
1. Reinstall drivers manually through Device Manager.
2. Use another USB-port (preferably) USB 2.0).
3. Disable antivirus and firewall for the time of firmware.-->
4.Battery problems: how to diagnose and eliminate
If Xiaomi doesn’t turn on and react to charging, it could be the battery that’s to blame, especially for phones older than 2-3 years, where battery capacity drops below 70%.
Signs of a faulty battery:
- 🔋 The phone does not turn on, but vibrates when charging.
- 🔌 The swelling is then turned off (and then turned off).
- 🔥 The phone is very hot when turned off.
- ⚡ The battery is discharged in a few hours without using.
How to check the battery without disassembling: Connect the phone to charging → wait 30 minutes → Press and hold the power button for 20 seconds.
If the charging indicator (red light bulb) comes up, the battery is alive, but it may be damaged. If there is no reaction, the battery is completely discharged or defective.
For accurate diagnosis, you can use a voltage tester (multimeter): Connect the probes to the contacts of the battery (red to the battery "+", It's black to "-." Normal:
- 🔋 3.7-4.2 B - Battery is in good working order.
- 🔋 3.0-3.6 V - deep discharge, charging with a special device is required.
- 🔋 Below 2.8V – Battery malfunctions, need replacement.
⚠️ Note: If you choose to replace the battery yourself, use only original batteries or certified analogues (for example, from Baseus or Remax). Cheap Chinese batteries can swell or damage the board! On Xiaomi models with Battery Health feature (such as Xiaomi 13 Ultra), the non-original battery can block fast charging.
5. Hardware malfunctions: when repairs are needed
If none of the software methods worked, the problem is probably hardware, and let's look at the most common breakdowns and their signs.
Top.-5 Xiaomi hardware malfunctions:
| Problem. | Signs. | Decision |
|---|---|---|
| Damaged battery plume | The phone does not turn on, but reacts to charging (vibrates) | Replacement of the plume (cost) ~500–1000 ₽) |
| Failed power controller | The phone is not charged, the battery is not determined | Repair of the board (soldering of the new controller) |
| Oxidation of contacts after moisture | The phone turns on after a while, the sensor glides. | Cleaning with alcohol + drying (in service) |
| Faulty memory chip (eMMC/UFS) | The phone is loaded to the logo and turned off. | Chip replacement (expensive, often impractical) |
| Damaged charging connector | Charging is only in a certain position of the cable. | Replacement of the connector (~1500–2500 ₽) |
How do you know if your phone needs repair, not firmware? Run the test: Connect your phone to your PC → Open Device Manager. → Check if it is defined as Qualcomm. HS-USB QDLoader 9008” or “or” or "MTK Preloader".
If you do, you have a chance to repair your phone through firmware, and if you don't, it's an iron problem.
Cost of repairs in service centers (2026):
- 🔧 Battery replacement: 1500–3000 ₽ (model-wise).
- 🔌 Repair of the charging connector: 1500–2500 ₽.
- 🔥 Diagnosis of the fee: 500–1000 ₽ (Free of charge if you agree to a repair).
- 🖥️ Replacement of memory chips: from 5000 ₽ (on new models is often inappropriate).
⚠️ Warning: If your Xiaomi hits the water, don't turn it on and plug it into charging! immediately remove the battery (if possible) and take it to the service. Turning on a wet phone can cause a short circuit and irrevocably damage the board. In 80% of cases, Xiaomi is able to recover after water, if you act in the first 24 hours.
6. Specific problems of Xiaomi models
Some Xiaomi models have unique "diseases" that lead to cyclical reboot or power failure.
Redmi Note 8 Pro and others on Mediatek Helio G90T):
These phones often suffer from boot partition damage after a failed update.Solution:
Squeeze through SP Flash Tool with a tick only on "Download" DA"
Xiaomi Mi A2/A3 (Android One):
These models often have a persist partition that goes off, which leads to endless loading.

POCO F1/F2:
There are problems with overheating and chip dumping, and if the phone turns off when you're loading and doesn't turn on, check:
Processor temperature (if the phone is switched on at least occasionally) and integrity of the soldering of the eMMC chip
Redmi 9/9A/9C:
Often suffer from a failure of the power controller MT6358. Signs:
The phone doesn't turn on, but when you plug in to charge, the light lights up briefly, and the only solution is to replace the controller in the service.
Xiaomi 12/13/14:
On the flagships may have a conflict with the module 5G, leading to reboots:
