Reasons for rebooting
Before diving headfirst into the problem, let's clearly define what bootloop is . Translated from English it means cyclic loading.
The Xiaomi logo appears , but things don't go further. The bootloader cannot do the main thing, the system does not start for some reason and everything repeats again.
Another possible option: a working phone suddenly turns off and reboots. There are no patterns in time. Once a minute or a day, a malfunction of the device may occur at the most inopportune moment.
The reasons for this disgrace in 95 cases out of 100 lie in the incorrect operation of the Android system software. What does it mean?
- It is corrupted by thoughtlessly editing system files after rooting. Fine tuning leads to thick circumstances. From the series: Don’t give the monkey a Kalashnikov.
- The update arrived by air, but it turned out to be “second-class”. There is no guarantee that the new version of MIUI will be bug-free.
- Independent actions to flash the device turned it into a brick. An OS was loaded that was incompatible with the device. Either the downloaded version has errors or is not for your device.
- The flashing process was completed by turning off the power. Cruel trouble. Although everywhere they write and shout about the need to pre-charge the battery, certain individuals manage to get themselves into this story. An update completed abnormally results in a cyclic dance with tambourines around the logo.
- As for viruses. Some are inclined to complain everywhere about a certain “hand” of Moscow (figuratively speaking). I admit that there is a virus inside the phone, but it can only do something nasty if you have root rights. Rare case.
- The installed application, just before the bootloop, turned out to be broken and malicious.
The remaining reasons are hardware in nature.
- Occasionally this is due to a low battery charge or a malfunction of the battery itself and the control circuits.
- The smartphone fell on the floor, water got into it, or a pet mistook it for its toy. In these and hundreds of similar cases, damage is possible, both mechanical and electronic.
- The chipset, RAM, and communication modules are damaged and need repair.
Reason 3: worn out battery
The average battery life is 5 years if used carefully. Intensive use or regular use of fast charging reduces the operating time to 1.5-2 years, after which the battery usually swells, which leads to a reduction in autonomy. Another sign of a used resource is a sudden shutdown or reboot, both during idle time and under any load.
Solution: replace the battery
A worn out battery must be replaced. It’s also worth considering a replacement if your smartphone turns off in cold or heat.
What to do when a reboot loop ends at the MIUI logo
I don’t want to brag, but I have some experience in “lifting” Xiaomi phones from my knees. I don’t recommend taking on this matter hastily; nothing will come of it.
Still, certain knowledge must be present. Otherwise, you can simply finish off the smartphone; not every workshop will undertake to eliminate other people’s jambs, due to the fact that the process of restoring the device becomes many times more complicated.
Let's start resuscitation.
The best thing you can do, if, of course, you are sure that the firmware was not damaged and the bootloop occurred for a different reason, is to turn off the smartphone and enter the recovery menu. We press the volume + and - keys together with the power and find ourselves in TWRP. Naturally, it must be installed in advance, along with the unlocked bootloader. Select wipe data and do a full factory reset.
This procedure helps devices with an undamaged operating system. Returning it to "out of the box" condition solves all problems. Unfortunately, it cannot always be applied. You cannot do this procedure on stock recovery.
The next point is to make sure there is a charge in the battery, otherwise connect the charger. After charging, turn on the smartphone again. If the reboot fails, there are not many options left.
Reflashing the device.
Or rollback to an old working version, especially important in case of an unsuccessful update. But there are too many conditions that may not be collected at the right time.
- unlocked bootloader;
- installed TWRP;
- backup made on time, version of the working OS.
If you have everything listed, then there are no problems, go into recovery and restore the backup.
I didn’t have such an opportunity and had to harness myself to the fullest. The flashing procedure for Xiaomi phones online is described in detail; in this article I only mention it as the main method of solving the problem. You will need the Mi Flash flasher program, device drivers and the firmware itself.
In especially severe cases, when the device is not detected on the computer, you will have to use the SP Flash Tool and Qualcomm USB Driver.
But if nothing happens, the Mi logo is on and nothing else happens, then the question of returning to working condition is very pressing. A failed procedure with the firmware will lead you to the only solution: contact the service center.
Rebooting a frozen Xiaomi phone
There are three ways to restart your smartphone. The first method is a soft reboot, usually used when the phone freezes slightly. The second method is a hard reboot. Used when the device freezes completely. The third method is experimental; you will read its description below.
Soft reboot
The main condition for performing a “soft” reboot is the working state of the smartphone and its system.
So:
- press and hold the power button;
- in the menu that appears, select “Reboot”;
- confirm the reboot;
- We wait for the smartphone to turn on and check its functionality.
Hard reboot
Used when the smartphone system freezes completely. Determining this state is extremely simple - the phone does not respond to the sensor, pressing the power button and to your pleas, threats and curses (just kidding :)).
In this case:
- press and hold the power button for about 20 - 30 seconds;
- after the “Mi” logo appears, release it;
- We are waiting for the system to turn on. If the smartphone does not turn on, press the power button again, but hold it a little longer.
In most cases, this way you can reboot Xiaomi. The only thing you must clearly understand is that if you worked on the device, the data after a hard reboot will be lost (will not be saved).
Experimental method
I would also call it “the old fashioned way.” You probably remember what you had to do before with your phone if it froze and did not respond to pressing the power button?
That's right, remove the battery.
Today, Xiaomi smartphones have a monolithic design that does not allow access to the battery without the use of special tools. But if your smartphone is frozen, the first two methods did not help, why not try?
Attention!! Violation of the integrity of the design of the smartphone will lead to loss of warranty on it. In addition, it is not safe and any mistake can turn your smartphone into a “brick”
There is no single instruction here; we look for videos on YouTube to analyze popular models. Let me remind you that this is an extreme measure, but since we are discussing ALL methods of rebooting, it has its place.
When the device constantly reboots after a few minutes of operation
Analyze your actions, when it started and what caused the bootlap.
Unsuccessful experiments with superuser rights and thoughtless actions with system files sometimes lead to disastrous results. The device begins to glitch and periodically turn off. Revert your settings to their previous state and restore changed system files. If an application was installed, remove it; it probably contains a virus. Coupled with root rights, it can independently ruin the OS.
If the device turns off during the game, it is worth checking the processor temperature and its frequency during startup and the game itself.
Some applications help control the heating inside the smartphone case and promptly alert the user about it. You are required to monitor the situation and draw a conclusion about this or that running game. Perhaps it is too “heavy” for your version of the smartphone and you should get rid of it. The Cooler Master application from the Play Market is suitable for this purpose.
The same applies to the load on the processor itself and its overclocking to critical values. This may cause the device to turn off. Install SetCPU, the Russian version, and using superuser rights, make the necessary changes in the operation of the chipset, and specifically, reduce the clock frequency.
Don't forget about flashing - suitable for any manifestations of bootloop. What to do and how to proceed is up to you to decide. It’s worth trying to switch to stable firmware, abandoning the developer one. This will clarify the root cause of the failure of the smartphone.
The strategy here is this: flash the device, do not install any applications, and at the very minimum processor load, observe the operation of the device.
If the phone reboots again, then it’s time to look at the following circumstances.
What to do?
- As soon as the smartphone is turned on, you must quickly remove the last downloaded program, as it may contain violations or viruses. After this, be sure to restart your phone;
- Sudden shutdowns during operation can be caused by high temperatures inside the case due to resource-intensive games. In this case, you need to remove it or wait for a new operating system update. You can also notify the manufacturer about problems with your Xiaomi model when the load on the hardware increases;
- An extremely high chipset frequency can also cause the device to turn off immediately. This may happen in normal mode or when using a demanding application. Using the “CPU Setting” program, obtain superuser rights and slightly reduce the maximum processor frequency, by about a few percent, and monitor the result. If the number of reboots has decreased, try reducing the numbers a little more;
- Transfer all the necessary information from your smartphone and reinstall the operating system using the latest stable software version.
In general, the main causes of bootloop are software failures that are caused by the latest updates or incorrect applications. If all the options for solving the problem do not solve it, then it is likely that there is a hardware problem. The failure may be in the battery, RAM or internal memory of the device.
You should also take into account the possibility of manufacturing defects, which can often be noticed during the first time of use. In any of the mentioned situations, you should contact the service, it does not matter whether there is a warranty, since diagnostics are required.
Alternative causes of loading loops
These are hardware reasons, there may be quite a few of them. Xiaomi restarts if there are malfunctions in the chipset, memory, both RAM and full, communication modules. In a word, when your motherboard is acting up.
It is extremely difficult to diagnose it, like other possible breakdowns in the phone, at home. This will require you to have special equipment and, more importantly, specific knowledge at the intersection of different areas. This is programming and electronics.
Even the battery will require a clear answer from you about its serviceability. Not to mention the charge controller. For a comprehensive answer to all the questions posed, there is only one way out.
These tasks are best handled by craftsmen from specialized repair centers, which are located in any large populated area.
Reason 5: presence of viruses
Various malicious applications or miners can overload the system. As a result, the hardware capabilities become insufficient and the phone freezes or overheats, which leads to a power outage.
Solution: scan for and remove viruses
It is necessary to scan the system with antivirus applications, provided that the phone does not turn off when trying to download or run the program. Otherwise, you should try scanning the system from safe mode.
If this didn't help?
In some cases, the problem is overheating of the board and the battery. The gadget can be restored, but the cost of this action is unreasonably expensive.
In the assortment of Xiaomi phones in the Droid-Market store, you can choose a new smartphone with powerful technical characteristics, which will avoid reboot problems. The purchase of products is carried out through a basket of goods; advice can be obtained through contact means of communication, including through the social networks Instagram and.
