Xiaomi’s endless reboot, causing the owner to panic to look for a solution, is quite common: the screen goes out, the Mi logo appears, then the process is repeated over and over again, not even allowing you to go to the menu.This phenomenon, known as bootloop, can be caused by both a banal software glitch and serious problems with the “hardware”.
In most cases, a device can be brought back to life without going to a service center if you act consistently and in a cold blooded manner. Cyclical reboot often occurs after a failed update, memory overflow or installation of incompatible software. Understanding the nature of the problem is the first and most important step to restoring your gadget to health.
Don't carry the phone to the master right away unless you've tried basic diagnostics. Often the problem is a sticky power button or a conflict of apps that you can fix yourself. Let's take a look at the algorithm that can help you resuscitate Redmi or POCO.
Primary diagnosis and simple solutions
Before we go into the complex manipulation of the Recovery menu, we need to rule out the basic physical reasons. The power button is the most vulnerable design element that, when used frequently or moisture is ingested, can stick inside the case. If the button is constantly pinched, the phone will perceive this as a command to reboot.
Try to press the power button carefully but forcefully several times to stir up the mechanism. Also remove the protective case that can press the key. If the phone was in water or in a damp environment, dry it with a hairdryer (not hot air!) for 10-15 minutes, paying special attention to the button area.
⚠️ Warning: If the phone falls or gets wet, don't charge it right away.A short circuit can permanently disable the motherboard.
The second important aspect is the charger: An unstable voltage or a faulty cable can cause a power controller to malfunction, which looks like an endless power cycle. Use only the original power supply and cable to rule this out.
Sometimes it's a crowded internal memory, and when the space is completely out, the system has nowhere to create the temporary files it needs to work, and it goes into reboot, and a PC connection can help if the phone is detectable, but more often it requires logging into Recovery mode to clean the data.
Enter Recovery and Hard Reset mode
If simple methods don't work, you'll have to resort to more radical measures. Recovery is a special recovery environment built into the firmware that allows you to control the system regardless of the main interface. To log in on a switched-off device, press the power button and Volume Up button at the same time.
Hold both keys until the Mi logo appears, then release the power, but keep the volume up. You'll see a menu with a few points in English. The navigation is done with volume buttons, and the choice is with a power button. You need a Wipe Data item.
☑️ Reset algorithm
Select Wipe Data, then Wipe All Data, and confirm the action.This process will completely delete all your photos, contacts, and apps, but is often the only way to save your phone from software bugs. Once you've finished, select Reboot and wait for the first turn on, which can take up to 10 minutes.
It's important to understand the difference between Hard Reset and a normal setup reset. Hard Reset touches the system partition and removes all traces of user activity, returning the phone to the "out of the box" state, which is effective against viruses and deep software conflicts.
Software failures and system updates
A common cause of instability is a failure in the MIUI or HyperOS update process. If the battery runs out during the installation of a new firmware version or the Internet is interrupted, the system files can be damaged, in which case the phone tries to boot, detects an error and restarts.
If the phone still boots up and logs in, check for updates immediately. Go to Settings → About Phone → MIUI. If an update is available, try installing it. If the problem occurs after the update, sometimes reinstalling the same version through the update menu helps.
What to do if the menu is not loaded?
Application conflicts can also cause cyclical reboots: If you install software from unknown sources or modify the system (getting Root rights), they may be the culprits. In Recovery mode, sometimes the Safe Mode option (on some models) is available, which only downloads system applications.
For advanced users, there is a Fastboot reset, a low-level mode that allows you to reflash the device from your computer, press the power button and Volume Down to enter it, and you'll see a picture of a hare repairing an android.
Problems with memory and storage
One hidden but serious cause is the degradation of the embedded memory of eMMC or UFS. Over time, memory cells wear out and the phone stops recording or reading system files correctly, often on older models or devices that have been actively used to record videos and games.
The symptoms of memory problems are not only reboots, but also freezes, slow interfaces and errors in installing applications, so a software reset can only have a temporary effect or not help at all, and the only solution is to replace the memory module in the service center.
Another factor is /data partition overflow. If you deleted all the files but the phone is still hanging, the file system may have been damaged. In the Recovery menu (Connect with MIAssistant), you can try connecting the phone to your PC and clearing the partitions manually if you have the appropriate skills.
You can use a special tool to diagnose the state of the drive, if the phone is even occasionally turned on. Pay attention to the system logs, where there may be disk reading errors. However, at home, it is difficult to accurately diagnose dying memory.
Hardware malfunctions and soldering
If software methods are powerless, the problem is probably hardware. CPU or memory dump is a common problem with today's thin smartphones when they fall or overheat. The chip goes off the board and the contact goes missing, leading to an endless reboot cycle.
It's also worth checking the battery status. If the battery is severely worn out, it may not be giving the required current at peak load when the system starts.The phone tries to turn on, the voltage drops, and it shuts off.Replacing the battery often solves the problem on devices older than 3 years.
⚠️ Warning: Don't try to disassemble your phone yourself if you don't have experience. Damage to plumes or connectors can make things worse.
Oxidation of contacts after moisture is another enemy, and even if the phone is high, the salts could stay on the board and cause a short circuit, in which case ultrasonic cleaning of the board in the service is necessary.
Below is a table that helps classify symptoms and possible causes:
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Reboot on the Mi logo | Firmware failure, damage to system files | Wipe Data, flashing it. |
| Black screen and vibration | Display or plume malfunction | Display replacement, plume check |
| Cycle after fall | CPU/memory dump, board damage | Warming up (rebolling) in the service |
| Rebooting when charging | Failure of the power controller or battery | Battery replacement, power chain repair |
| Spontaneous restarts | Overheating, viruses, application conflict | Cleaning cache, removing software |
Prevention and outcomes
To avoid a repeat of a constant reboot situation, follow simple rules of operation: do not allow the battery to completely discharge to zero, as this damages the chemistry of Li-Ion cells. Regularly free up space in internal memory, leaving 10-15% free space for system operations.
Avoid installing apps from questionable sources and don’t interrupt the system update process. If you notice your phone is heating up or running slower, this is the first signal of possible problems.
💡
Turn on automatic sync of contacts and photos with your Google account. This will take a couple of seconds in the settings, but will save your data in case of any crash.
Use only quality charging accessories. Cheap cables and power supplies without certificates often give voltage surges that negatively affect the power controller and memory of the device. Original accessories Xiaomi or proven brands are more expensive, but keep the health of the gage.
💡
90% of cyclical reboots are solved by a data reset (Wipe Data), but if the problem is hardware, only the service will help.
To sum up, Xiaomi's constant reboot is often a software glitch that is eliminated by a reset. However, if your phone falls or gets wet, prepare to visit the workshop. Competent diagnosis begins with eliminating simple causes and sequentially moving to complex ones.
