After the update, the Xiaomi smartphone does not turn on: reasons and solutions

When Xiaomi does not turn on after updating orbegins to overload on its own, many panic. Especially if the device does not show signs of life in the hands of an inexperienced user or someone who first encounters such a problem. The first piece of advice would be to set aside panic and realize that not everything is so scary and you can “revive” your smartphone. Just a few correct manipulations, and you can cope with the problem yourself. For completeness, we have collected real situations and feedback from readers of news about mobile phones on the Andronews website.

Let's make a reservation right away that if problems withdue to water getting into the device, under no circumstances connect it to the mains or press any buttons. Dry the phone as quickly as possible and proceed with the manipulations described below, only after that. But only when you are sure that the Xiaomi smartphone is really "dry", otherwise - seek help from specialists.

Xiaomi smartphone does not turn on, does not respond to button presses. What to do?
Even those who are careful withsmartphone, there are times when it accidentally ends up on the floor. If it is dressed in a cover, then there is a chance that visible damage can be avoided, but the internal components may well suffer from an unplanned fall. The consequences of an impact can be very different: from breakdowns in the contact between the chip and the motherboard to a short circuit and failure of the power controller. A sign of a short circuit is a noticeable heating of the case. If there is damage to internal components, then a trip to the service center cannot be avoided.

But what if the Xiaomi smartphone did not fall and stopped showing signs of life for no reason?

The first two ways to reanimate a mobile phone:

1. Reboot.It often happens that a simple reboot allows you to bring your smartphone back to life. To perform it forcibly, you have to press and hold the power button for 7-10 seconds. In this case, the Xiaomi phone should give a short vibration response and start to start.
Alternative option is to reboot fromservice menu (Service Recovery) if the system freezes. To get into the engineering menu, you must simultaneously press the volume rocker and the off key. The next step is to turn off your smartphone and try to start it up again.

2. Reflash if reboot does not help.This is a difficult way and the uninitiated should refuse to implement it and turn to specialists. If you take up its implementation on your own, then you must:
• from a personal computer visit the official Xiaomi website and find the latest current firmware for your device model;
• fully charge your smartphone;
• connect your smartphone to your PC, select "File Transfer";
• move the installation file to the system folder;
• install the firmware.

Technical problems not caused by the user
It so happens that a Xiaomi smartphone is completelyserviceable, but does not turn on and all the manipulations with the reboot did not work. It is possible that the problem is in the power button. The key should be firm, not wrinkled and responsive to pressing. There are cases when a non-original cover interferes with turning on a Xiaomi smartphone. Remove the device from the protective clothing and try to turn it on.

The problem may also be related to the battery.Now the lion's share of Xiaomi devices have non-removable batteries. And this means that it will not work to replace or check the health of the power source on our own. The first thing to do is try to charge your smartphone. Perhaps it is simply discharged or the battery level has dropped so that connecting the charger does not solve the problem.

Put the device on charge for 1-2 hours.After this time, try to turn on the smartphone by long pressing the power key. Phone not responding? Start the phone in fastboot or recovery mode. You can call the desired mode by simultaneously pressing the power and volume keys. If you entered the fastboot, turn off the device with a long press. And now you need to connect your smartphone to a power source for "refueling".

But do not forget to check the USB cable for serviceability. The easiest way is to recharge another device with it. If power is supplied, the cable is functional and can be used for charging.

Another malfunction - no contactbattery cable and connector on the motherboard. The case is rare, but it still happens and should not be ruled out. And only a specialist can identify this malfunction by means of "opening". Therefore, you have to contact the service center, where they will issue a verdict whether there is this breakdown or not. It is worth seeking help from professionals even when the USB connector itself is faulty, which could not withstand the frequent and "vandal" connections of the charging cable.

Smartphone won't boot after update or flashing
Enthusiasts often experiment and try"Roll" custom firmware to your devices. But no one guarantees that the software is free of bugs and vulnerabilities. Also, it is not uncommon for a user to mistakenly install firmware on a gadget that is not intended for him. You need to be careful and start downloading the firmware designed specifically for your device. It will not be superfluous to download software from trusted third-party sources.

Before proceeding with installing the firmware,make sure that the battery charge exceeds 50%. With a lower charge level, there is a risk that the Xiaomi smartphone will go into a bootlap (endless reboot process) or even turn into a "brick". In the case of stable official versions of the MIUI shell, this problem does not arise. The system will not allow updating if the battery charge is insufficient, and will notify the user about it.

The smartphone is frozen at the start of the download
If you activated your smartphone, athe Mi logo and the download is in progress, but the smartphone did not turn on, which means that you are faced with a bootloop. The device goes into a cyclic reboot and cannot get out of it on its own. This is a system failure that can be fixed with a few tweaks:

• hold down the power and volume keys;
• open the recovery, select English;
• go Wipe - Wipe all data;
• confirm your choice;
• the settings are reset and the smartphone turns on.

If all of the above actions did not givethe desired result and the smartphone could not be "reanimated", then the only way out remains - a flashing. To do this, it is worth following the steps outlined in our article earlier.

Smartphone won't turn on after charging
As a rule, such a reaction of a smartphonesignals that the battery has reached the end of its life. And here you cannot do without replacing the battery. Indirectly, the deterioration of the power source and the fact that the charge level does not increase confirms that the charging indicator is constantly lit in one color and does not change to yellow or green (depending on the model).

It is worth remembering that the manufacturer does not offerinfinite number of battery charging cycles. They are generally limited to 500 cycles. In practice, this figure may be even less. Much depends on how often you send your smartphone to “refuel”. Make sure that the charge level does not drop below 15%. If your device “falls” below this mark with enviable regularity, the process of battery wear is accelerated and its service life is reduced.

Express method with microSD card
Experience shows that the failure of the Xiaomi smartphoneturn on is due to the fact that the memory card is crammed to capacity. To bring the device back to life, you need to remove the microSD card and return it to its original place after a short time. If this method did not help, then check all the other causes of the malfunction and how to eliminate them, which were described in this material.

The smartphone was on charge all night, but the battery life was not replenished
It so happens that in the evening you connected the device to the outlet, but in the morning you found that the battery charge was not replenished. Possible causes of the malfunction:
• it's time to change the battery, it is worn out;
• malfunction of the usb connector;
• damage to the power controller or it does not work correctly. We'll have to contact a specialist to fix the breakdown.

Conclusion
As you can see, in most cases you can returnXiaomi smartphone to life and without contacting a service center. But prevention is everything. It is better to warn than to deal with the consequences later. Therefore, we strongly recommend that you do not update your smartphone with a low battery charge, do not install firmware from third-party developers and use your smartphone carefully, avoiding falls, bumps and careless handling of it or the charger.

By following our guide, you can independentlyidentify the malfunction and eliminate it. But, if you are not confident in your abilities, and you are from technicians to "you", then seek help from specialists who will do everything quickly and professionally.
