The situation of your smartphone suddenly going out and then flashing its logo again, causing an endless reboot cycle, is familiar to many owners.This behavior of the device is not only annoying, making normal use impossible, but can also signal serious problems inside the operating system or hardware. Owners of Xiaomi, Redmi and POCO often face this, and panic in the first minutes is not worth panicking.
The reasons can be trivial, like a sticky power button, or complex, like a bootloader failure or battery degradation. It is important to consistently rule out software errors before carrying a gadget into service. In this article, we will discuss all possible scenarios, from simple actions to complex recovery via Fastboot.
The first thing to understand is, is it happening on the screen, or is it going into a bootloop right after the logo appears? That's what the strategy is, and if the device is able to show the desktop, the chances of software repairs without data loss are much higher.
The main reasons for the cyclical reboot Xiaomi
Understanding the root of the problem is half the solution, and most often, an endless reboot is caused by a software component conflict or physical damage, system files may have been damaged after a failed update or a power surge during charging, in which case Android cannot properly complete the launch and goes into reboot.
Physical factors also play a huge role: A discharged battery that does not hold current under the CPU load will cause blackouts at peak power consumption, and it is also worth checking the on button: if it is mechanically damaged or contaminated, the contact can close inside the case, forcibly restarting the phone.
⚠️ Warning: If the phone heats up in the lower part of the case or in the area of the camera before switching off, this may indicate a short circuit in the power supply.
Another common cause is conflicting applications that have received deep access rights, viruses or poor-quality software can block critical processes, and sometimes the problem lies in crowded memory, when the system does not have enough space for temporary startup files.
Primary diagnosis and simple solutions
Before you get to the tricky stuff, do a basic check. Make sure the accessories aren't the problem. Try replacing the charging cable and the power supply with the ones you know to be working. Sometimes, the unstable voltage keeps the phone from starting.
Check the mechanical buttons. Carefully, without undue effort, press the power button several times. If you feel that the button is difficult to move, or it does not "click" back, you may need to clean or replace the plume. In some Xiaomi models, the protective case can press on the keys, simulating a long press.
- 🔌 Try charging the device in a switched-off state during 30-60 minutes, even if the screen is not responding.
- 🔘 Extract. SIM-card and memory card (if any) as the damaged sector on the drive may cause a download failure.
- 🌡️ Let the phone cool completely if it’s hot, and try turning it on in a cool room.
If simple manipulations don't work, go to software methods. It's important to understand that some actions can lead to data loss, so always assess the risks. Redmi Note and POCO series are characterized by specific update bugs that are solved by resetting settings.
Software reset and entry into Recovery mode
If the phone is responsive to taps but reboots cyclically, enter Recovery Mode. This is a special recovery section that loads independently of the main system. To log in to most Xiaomi devices, you need to press the volume button and the power button at the same time.
Recovery menus are managed by volume buttons (up-down) and power button (select). You need to find Wipe Data. Be careful: choosing the Wipe All Data option will completely delete all your files, photos and contacts. If you can choose Wipe Data (Keep Files), use it, although this helps less often.
☑️ Checklist before data reset
After reset, the phone will suggest a reboot (Reboot -> Reboot to System) The first run can last up to 10 minutes. If the cyclic reboot stopped, the problem was a software glitch. If the phone went back into cycle, the situation is more serious.
⚠️ Note: After resetting data (Wipe Data) on modern versions MIUI And HyperOS will require you to enter a password from the Mi Account that was attached to the device, and if you don't remember it, unlocking the phone will be extremely difficult.
Using Fastboot Mode and Fastboot Flashing
When Recovery isn't working or is not available, Fastboot mode comes to the rescue, which is a low-level protocol for interacting with your phone via your PC, and to enter it, press the volume down button and the power button, and you'll see a hare fixing an android, or you'll see the words FASTBOOT.
If you log in to Fastboot successfully and your phone doesn't turn off in this mode, then the hardware (processor, memory) is probably intact. The problem lies in the bootloader or system. You'll need a computer, a USB cable and the Mi Flash Tool or Xiaomi ADB/Fastboot Tools to recover.
The process of flashing is as follows:
- Download the official firmware (Fastboot ROM) for your model from the site miui.com.
- Unpack the archive and install ADB/Fastboot drivers on your PC.
- Connect your phone in Fastboot mode to your computer.
- Run the script. flash_all.bat (For Windows, use the Mi Flash Tool.
What if the PC doesn’t see the phone in Fastboot?
It is important to choose the right firmware type. To eliminate cyclic reboots, you often need a complete cleanup, so in the Mi Flash Tool, choose the Clean All option. This is guaranteed to delete all data, but return the phone to factory state.
| Regime. | How to get in | What do you need? | Risk of data loss |
|---|---|---|---|
| Recovery | Volume + and Nutrition | Resetting settings, update | High (with Wipe Data) |
| Fastboot | Loudness - and Nutrition | Fixing, refurbishing | 100% (at Clean All) |
| Safe Mode | When loading (depends on model) | Diagnostics of applications | No. |
Hardware problems: battery, plumes and board
If the software is powerless, or the phone shuts down even in Fastboot mode, it's hardware. The most common reason is the battery. Over time, lithium-ion batteries lose capacity and can't produce the right current. When you try to start the processor, the voltage drops, and the protection goes off.
The second candidate is a charging plume or power button. In mechanical-button models, contact oxidation leads to false positives. In today's Xiaomi touch buttons, the problem may be the plume connecting the board to the body.
The most unpleasant option is the dump of the processor or memory (BGA-This often happens after falls or extreme heat, symptoms: the phone warms in a certain area, hangs on the logo or cyclically reboots.
💡
Battery check: If you have the option to open the back cover, disconnect the battery plume from the board. Connect the charger. If the phone is on and running stable (without the battery), then the problem is definitely the worn-out battery.
It’s also worth checking the charging connector. If it’s shattered or oxidized, the phone may not get enough power to start, going into a perpetual reboot when the cable is connected.
Specific problems of Redmi and POCO models
Sub-brand devices have their own peculiarities, such as the Redmi Note series (especially the 9, 10, 11) is known for problems with updating MIUI, after which the phone goes into a bootloop, often only solved by completely flashing through the Fastboot with cleaning.
POCO models (e.g., F3, X3 NFC) can suffer from CPU dump due to soldering and heating designs. If your POCO starts to shut down after a game or a difficult task, there is a high risk of hardware failure.
- 📱 Redmi: Frequent software failures after updates MIUI. Healable by discharge.
- 🎮 POCO: Prone to overheating and hardware defects of the motherboard.
- 🔋 Xiaomi (main line): Problems often involve a power controller or battery.
For users of custom firmware (LineageOS, Pixel Experience), cyclic reboot can mean incompatibility of GApps or damage to the boot partition, in which case, reflashing stock Recovery and returning to the official shell helps.
💡
If Xiaomi’s phone turns off and turns on itself, 80 percent of the time it’s done by a Wipe Data reset or flashing, and if it doesn’t work, it requires a battery replacement or a board repair.
