Your Xiaomi smartphone suddenly started spontaneously rebooting, getting stuck on the Mi logo or going into an endless reboot cycle? This problem is familiar to many owners of Redmi, POCO and Mi devices, from budget models to flagships. The causes can be both software (firmware failure, application conflict) and hardware (battery or motherboard malfunction). In this article, we will analyze all possible scenarios β from simple solutions to radical measures β and learn to distinguish between βtreatableβ cases from those when the phone requires repair.
It's important to understand that reboot is not always a critical error, sometimes it tries to fix a temporary failure, but if it's a regular reboot, it's a big problem, and we've put together proven diagnostic and troubleshooting techniques that are relevant to all versions of MIUI (including MIUI 14 and HyperOS), and let's start with the safest ways and gradually move on to more complex ones.
Reasons for Constant Reboots on Xiaomi
Before trying to cure a phone, you need to understand why it is rebooting, and the reasons can be divided into software (self-recoverable) and hardware (requires service center intervention), and these are the main culprits:
- π Firmware failure: Failed update MIUI, interrupted firmware installation or version conflict (for example, after manual downgrade).
- π± Application Conflict: Viruses, Incompatible Programs, or βCurvesΒ» APK-Files that disrupt the system.
- π Battery problems: Bloating, wear or malfunction of the power controller (often accompanied by a sudden shutdown at 20-30% charge).
- π Motherboard malfunction: CPU overheating, contact oxidation, or component failure (e.g., memory module).
- π οΈ Damage after repair: Incorrect replacement of screen, battery or other components leading to short circuit.
Typically, software failures occur after installing updates, root rights or third-party firmware. Hardware problems are more likely to occur after falls, moisture or prolonged use (3+ years). If the phone is rebooted only when connected to charging, either the cable / power unit or the charge controller on the board is to blame.

First steps: what to do when hanging on a logo or reboot cycle
If a Xiaomi smartphone hangs on the Mi/Redmi logo or goes into an endless reboot, donβt panic.
- Forced reboot: Press the power button for 10 to 15 seconds until the screen goes out. Then turn the phone on again. Sometimes that's enough to get out of the loop.
- Charging check: Connect the original cable and power supply. If the phone only reboots at low charge, the battery may be the problem.
- Extraction SIM and memory cards: Turn off the device, take out the tray from the SIM-card and microSD (if any) Sometimes a conflict with the memory card causes failures.
If these measures don't work, go to more serious methods, but remember: don't turn off your phone during a diagnosis (for example, when checking through Fastboot), or you risk exacerbating the problem.

If the phone is responding to button clamping but doesn't turn on, try holding the Power + Volume combination up for 20 to 30 seconds, which sometimes helps with "mild" loader failures.
How to enter Recovery mode and make a reset (Hard Reset)
If Xiaomi doesnβt load beyond the logo but reacts to buttons, try entering Recovery mode and perform a reset.This will delete all data, but often solves the reboot problem.
Instructions for most Redmi, POCO and Mi models:
- Turn off the phone (if it is on, press the power button for 10 seconds).
- Press Power + Volume up at the same time and hold until the Mi logo appears.
- Release the buttons and you will see the Recovery menu (in English or Chinese).
- Select Wipe Data (or Clear Data) and then Wipe All Data.
- Confirm the action and wait for the process to be completed.
- Reboot your phone with Reboot β Reboot to System.

β οΈ Note: After resetting, the phone will require you to enter the Mi Account that was previously linked. If you forget the password or do not remember which account the device is linked to, you will not be able to activate the device after Hard Reset (Mi Account protection). In this case, you will have to contact the service center for unlocking.
Fastboot Firmware: When Recovery Doesn't Help
If Recovery resets don't solve the problem, or if the phone doesn't respond to buttons at all (except vibrations), you'll have to reflash it through Fastboot, which requires a computer and special tools, but it's effective even in severe firmware failures.
You'll need:
- π» Windows computer (or Mac/Linux fixed ADB/Fastboot).
- π Original. USB-cable (better from the set).
- π Firmware for your model (download from the official Xiaomi website or forum) 4PDA).
- π οΈ Mi Flash Tool (for Windows).
Step-by-step:
- Unpack the firmware in a folder without Cyrillic characters (for example, C:\Xiaomi\proshivka).
- Install the Mi Flash Tool and drivers for Xiaomi.
- Turn off the phone and press Power + Volume down to enter the Fastboot (the image of a hare in a hat-eared will appear).
- Connect your phone to your PC. In the Mi Flash Tool, select the firmware folder and press Refresh, the device must be determined.
- Select Clean All mode and press Flash.
- Wait for the finish (10-15 minutes) and restart the phone.
What if the Mi Flash Tool can't see the phone?
β οΈ Note: Fastboot Flashing deletes all data, including photos and apps. If you have synced with Mi Cloud enabled, some of the data (contacts, notes) can be restored after you log in to your account.
Diagnostics of hardware problems: when the "iron" is to blame
If all the software methods have been tried, but Xiaomi is still restarting, it's probably a hardware malfunction.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Reboot when connecting charging | Failure of the power controller or battery | Replace the battery or diagnose the charge |
| Overheating and offloading | Thermopaste on the processor dried or damaged radiator | Cleaning and replacing thermopaste in the service |
| Random reboots for no reason | Oxidation of contacts on the motherboard | Disassembly and cleaning with alcohol (only for experienced) |
| The phone doesn't turn on after falling | A plume break or a crack on the board | Diagnostics at the service center |
For self-checking:
- Try to start the phone without SIM-Maps and microSD β if the reboots stopped, one of the modules is to blame.
- Check the battery to bloat: put the phone on a flat surface and spin it. If it's playing or the screen is up, the battery is swollen.
- Connect your phone to your PC and check logs through ADB (adb logcat command).If there are many battery or thermal errors, there is a power problem or overheating problem.

If the phone only reboots when using the camera or mobile internet, either the camera module or the antenna plume is to blame.This is a typical problem for the Redmi Note 8/9 after falls.
Frequent questions and errors when removing reboot
When trying to solve a problem with constant reboots, users often make mistakes that only make things worse.
- β Use of informal firmware: Installation of custom ROM (For example, LineageOS on a locked bootloader can turn the phone into a βbrickΒ».
- β Interrupting the firmware process: If you turn off the cable during a Fastboot, the phone may stop turning on at all.
- β Ignoring backup: Many forget to save data before resetting, losing photos and contacts.
- β Self-repair without experience: Disassembling a phone without tools and knowledge often results in damage to plumes.
If you are not sure of your actions, it is better to contact the Xiaomi service center or a proven master.The cost of diagnosis is usually low (from 500 rubles), but you will avoid the risk of finally breaking the device.
Prevention: How to Avoid Reboot Problems in the Future
To minimize the risk of repeated failures, follow these guidelines:
- π Update regularly MIUI, Do not install beta unless you are ready for bugs.
- π΅ Avoid βleftβ firmware and rooting without needing to.
- π Keep an eye on the battery: do not discharge the phone to 0% and do not use unoriginal charges.
- π‘οΈ Install antivirus (e.g. Mi Security) and do not download APK unverified.
- π§ Periodically clean the cache through Settings β Memory. β Cleanup.
If your Xiaomi is no longer warranty-worthy, it makes sense to put it in a preventive cleaning service once a year (dust removal, heat paste replacement) that will prolong the life of the device and reduce the risk of hardware failures.
