software ways to fix problems

Reboot

If the sensor is not working partially, download the Rebooter app to help you quickly reboot your device. If the sensor is completely unresponsive and the smartphone has a removable battery, just remove the battery for a couple of minutes.

With devices that have a non-removable battery installed, you need to do a little differently.

Xiaomi device owners can hold the on/off button for 20 seconds or longer and the smartphone will restart or turn off. If this does not work the first time, try again, but hold the buttons longer. Owners of devices of other brands with a built-in battery should also try the above options.

If pressing the buttons does not give any result, wait until the battery is completely discharged and take the device in for repair.

redmi 9t won’t turn on after update/redmi 9t won’t turn on after reboot/Here’s How You Fix It

Removing the memory card and SIM card

Sometimes a memory card or SIM card is to blame for a touchscreen malfunction. To check this, turn off Xiaomi Redmi, remove both cards. After reboot, check if the problem is gone.

Through safe mode

Turn off the device completely. Then press the power button and do not release it until the smartphone logo appears on the screen. After that, release and press the volume down button. Release it when the device boots up and “Safe mode” will appear on the bottom left of the screen.

If no problems with the sensor are found in safe mode, then the problem is one of the applications that needs to be uninstalled or updated to the latest version.

hard reset

This is a full factory reset of the Xiaomi device.

Before resetting your phone to factory settings, do not forget to backup all important data stored on the device.

Display calibration with third-party programs

The Play Market has applications that can be used to calibrate the touch display, improving its performance. Reviewing all the applications will take too long, so we will focus on one of them, which received the highest score from users.

TouchScreenRepair

This Android app does two things:

  • conducts testing and issues a report on which fragments are not used, why the accuracy is low and the screen sensitivity is lame;
  • fixes errors automatically.

The application has an additional function. it allows you to change the orientation of the screen. You can select the area, when pressed, the response will occur in another part of the display.

If the sensor stopped working on Xiaomi, the cause may be a physical impact or a software failure.

Options for harmful physical impact:

  • a strong blow or fall from a height;
  • liquid contact;
  • a sharp temperature drop;
  • dents, scratches and cracks on the screen;
  • unsuccessfully glued film or protective glass;
  • serious pollution.
  • overloading the operating system with a large number of applications;
  • incorrect operation of some programs;
  • changing smartphone settings;
  • incorrect recognition of touches by the sensor;
  • inappropriate or unstable firmware.

TSP Dot Mode and TSP Grid Mode Tests

To conduct this test, you need to get into the Xiaomi engineering menu. To do this, dial the service code. It may be different for different manufacturers and phone models, try these options:

  • TSP Dot Mode. allows you to check the screen in “dot mode”. In the place where you will touch the display, there should be a cross.
  • TSP Grid Mode. testing takes place in the “grid mode”. The screen is divided into several rectangular parts. When a particular rectangle responds to touch, its color will change.

This test will tell you which part of the screen has a problem.

Developers do not advise trying to repair the phone on their own, as this requires certain knowledge and experience.

Tapping around the perimeter of the screen

This is the easiest way to test the display, which does not require installation of programs or other complex manipulations. Just gently press your finger across the entire surface of the display, especially in problem areas. Start with low pressure and gradually increase. Then slowly decrease the pressure.

Launch the keyboard and press each key. Try moving app shortcuts across the entire screen. In this case, pay attention to the sensitivity of each section of the display. Pause at the corners of the display, focusing on the bottom. Such testing will give you all the information about the sensitivity of the touchscreen.

Dry after getting wet

If moisture gets into Xiaomi, follow these instructions:

  • turn off the power;
  • remove the battery (for devices with a removable battery);
  • remove the SIM card and flash drive;
  • wipe the device with paper towels or a cloth that absorbs moisture well;
  • remove headphones, cases, film or glass from the screen;
  • place the smartphone in a bag filled with rice. Leave the device in this position for 12 hours. During this time, the croup will draw all the liquid out of the phone.

If the procedure with rice does not give the desired effect, contact the service center.

Check loops

A problem with the cable can be determined even without disassembling the phone. Sensor malfunctions are one of the signs of such a problem. Pay attention to the following signs:

  • the smartphone began to “slow down” during operation;
  • the device turns off when you unlock;
  • camera malfunctions.

If, in addition to problems with the sensor, the above appeared, then there are definitely problems with the cable. But you should not repair it yourself, because for this you need to be well versed in the smartphone device.

Sensor Replacement

If your smartphone does not use OGS technology, you can try to replace the sensor yourself. To do this, you will need the following tools and fixtures:

  • a set of small curly screwdrivers (available for sale specifically for smartphones);
  • mediator, spatula, plastic card;
  • silicone suction cup with ring or loop;
  • ordinary hair dryer;
  • glue B-7000 or equivalent;
  • thin rubber gloves.
  • Disassemble your smartphone.
  • Heat the display with a hair dryer around the entire perimeter to a temperature of about 70-80 degrees. Pick up the heated screen with a suction cup, and pull it off the case.
  • Install a new sensor. Prepare it by removing the protective film from the inside. Apply a thin layer of adhesive over the entire area of ​​the seating surface. Put the sensor back in place and gently press it down. You can put a small and flat object on top of the screen, weighing no more than 300 g, so that it sticks better.
  • You can collect the phone. Connect the cables, fix the internal threaded connections and install the external parts of the housing.

If you are not sure that you can handle the sensor replacement yourself, take the phone to a service center. Self-repair of the device will void the warranty on the smartphone.

How to save data when the display is not working

If the Redmi screen stops working completely and you want to keep the files on your phone, you will have to use a regular PC and a special program.

Broken Android Data Extraction

iSkysoft has developed a program that allows you to save or restore the necessary information from broken phones. To do this, install the Android Data Extraction application on your computer and follow the instructions.

  • Connect your smartphone to your computer with a wire.
  • Open the program, section “Data Extraction” (Damaged Devices).
  • Select the type of file to recover.
  • Indicate the current state of the smartphone: a) “Sensor does not work”; b) “Black/broken display”.
  • Enter the smartphone name and model. Then click “Next” and “Confirm”.
  • Turn off your smartphone.
  • Continue the process of saving data on the computer.

The touch screen of modern smartphones is quite fragile, so it can easily fail. You can always try to repair the touchscreen yourself or take it in for repair if the breakdown is difficult.

Control your device

Your new Android phone is practically set up. However, it is also highly recommended to install tools that will allow you to monitor and control battery, CPU or memory consumption and data transfer. Here are some of the best deals:

  • Onavo allows you to control data transmission over the Internet.
  • 3G Watchdog even more detailed than Onavo, also available as a widget
  • AutoKiller automatically closes inactive applications to save CPU and battery power
  • JuiceDefender helps save energy

  • Perfect Keyboard (many personalization options)
  • Go Keyboard (perfect for tablets)
  • Swype (classic gestures)
  • SwiftKey (good at predicting what you want to write)

When the quality of the pixels is determined, and among them it was possible to detect “burnt out”, you can start looking for applications that will correct the situation:

  • JScreenFix is ​​easy to use, you need to use the Fix Stuck Pixels button to get started. The developer promises 30 minutes to complete this operation, but the service center masters recommend leaving the devices. At least 10-12 hours for a more complete check;
  • Pixel Fixer: Another program similar to JScreenFix. To restore the pixels, you also need to click on the green button;
  • “Dead Pixel Treatment”: The platform not only tests a mobile phone for dead pixels. And then “heals” them, but at the same time reveals other defects in the display.

When using applications, it is recommended that the device not be disconnected from the chargers for the duration of the “treatment”. During pixel processing, the smartphone is constantly on, so the charge may not be enough.

Screen microcracks are fraught with a break in the power circuit. If this happens, then you will have to change the screen. Fortunately, in China they are several times cheaper.

It happens that the malfunction lies in the incorrect installation of the SIM card or flash drive. Try to take them out and see what happens.

A card with problems can be repaired by restoring broken clusters using a PC.

If shaken, a badly exposed plug from the display may fall out. What will entail disabling the image transmission module, or partial shutdown.

Remove the cover of the device, and plug the cable into the socket. If it is inserted, then take it out and insert it. In this case, do not forget to disconnect the power cable from the battery.

Resource select apps

Perhaps the MIUI interface is not allowed to fully charge the applications installed on the smartphone. As soon as you connect the charger, the programs begin to update, work with plug-ins, and conduct checks. As a result, the process is delayed indefinitely. Xiaomi 5 plus repair, smartphone glitches, spare parts available, average rating 4.5.

In this case, it is worth downloading a program for manually checking Android, which will analyze the operation of the system and help identify malicious monsters. Get rid of such harmful applications mercilessly.

Xiaomi Redmi 9 does not charge does not turn on What to do?

Why Xiaomi Redmi 9 does not charge, does not turn on, a common problem when using Xiaomi incorrectly, you must follow the instructions to start.

The problem was solved earlier on the forums:

  • What to do if Xiaomi writes 0% and does not charge?
  • My Redmi 9 turned off when I was playing, it had about 7% charge. I turn it on again, but it starts to boot and immediately turns off, the third time it did not turn on again. Now even when charging it does not turn on, what to do?
  • The input for charging in Xiaomi staggers a little, and the phone does not want to charge and turn on.
  • After the fall, Xaomi does not work, on charging, only the diode is on.

In this case, you should connect the charger to Redmi 9 and only then plug it into the outlet. Wait for some time (10-20 minutes) and try to start again.

If the problem persists, carefully inspect the USB cable and charger. They may be damaged and need to be replaced. Did you find any visible damage? But the wire can be broken from the inside. To be sure of its integrity, try using another charger. You can ask friends or go to the store. Replacing the charger allows you to accurately determine whether the charger is to blame or the whole thing is in the mobile phone.

If it is not possible to use the original device, recharge the device from a laptop by selecting the blue USB 3.0 port.

Try holding the power button longer. 20-30 seconds. Perhaps the gadget will revive from such actions.

Actions, how to act in such a situation

Changing graphics to low resolution will help. It is required to limit the power consumption mode. Do not continue to play with the phone charger turned on. Remove the phone from the case, allow general ventilation of the case. Turn off phone, remove battery.

If the smartphone was in a humid room, or moisture got on it. This is especially true of the USB input, and leakage into the smartphone. Oxides can lead to current leakage, and this contributes to the heating of the device. To fix, you need to clean the USB. Take a thin stick and wrap cotton wool around it. Dip it in white spirit or alcohol, and wipe the contacts at the entrance.

If water got inside, then you need to disassemble Meizu. And, carry out the same operation with contacts that are attached to the board. But, before doing this, disconnect the battery cable to avoid a short circuit.

If Meizu M8 does not have a microphone, for this you need to do the following.

Open the security settings, look for root access and click accept, reboot the device. Open the “phone” and enter this combination ##54298## or ##3646633##. Scroll to the right and find ” Hardware Testing “. audio. Audio Playback set the value of Heaset PGA to 160. Exit the menu and reboot the phone.

  • Replace the screen completely if there is real damage;
  • Update firmware and Flyme shell.

To carry out this procedure, you need:

  • Enter the device settings;
  • Select “About phone”
  • In the submenu, you will need to select check for updates. when you turn on Wi-Fi, everything will start downloading;
  • The device will reboot.

The appearance of stripes during use can be eliminated immediately after purchase by updating. This will not void the warranty. Unlike a complete flashing or self-repair in the same period.

A banal method is to simply log into your account on the device. Click on the item “Delete Mi account” below.

In this case, the account will be unlinked from the mobile phone. There will no longer be a message when the machine is booting up.

If Xiaomi has lost sound, you should first check the audio settings. If there is an active mode (with sound), then we continue to look for the problem.

Necessary. clean the headphone jack.

If the headset icon is on the screen of the Xiaomi smartphone, and the headphones are not connected, it means that the contacts are shorted. Therefore, the sound is transmitted to the headphones, even though they are not physically connected.

Reboot your phone after cleaning.

If during a call the interlocutor does not hear you well, then this function may be disabled. Go to the “sound and vibration” settings and move the “noise reduction” slider to the value “on”.

If it is activated, and there is crackling and noise during the conversation, then try turning off the function.

The built-in mobile assistant can also interfere with the normal operation of the microphone. Go to the settings menu. search Google. Next, turn off the voice finder feature. Restart your Xiaomi phone.

You can reset your account using Xiaomi support.

To do this, you must have documents on the phone. to confirm that it is not stolen.

How to talk to Xiaomi technical support.

Go to your mail service type and log in.

Click create message. In the first line, we write this address: mishu@Xiaomi.com Or this one: service.us@Xiaomi.com You can write in the subject (Unlock mi account). You must write in English. Use an online translator.

Next, we write what is required. I want to reset my Mi account on Xiaomi Redmi 6a. This procedure is long and may take 2-3 weeks.

Choose English and any country;

We make an Internet connection using Wi-Fi or cellular data;

We go to ” Privacy Policy” (Security Policy) and select any piece of text. On the right, click on the three dots, “Web Search” and “Google App”. Next, we can go to the settings by clicking on the “Settings” entry. We are looking for the item “About Phone” and click on it.

After logging in, click on “Software version (Miui version)”, which you need to quickly click a few (about 5) times until a notification appears about granting “Developer rights”. We go back and go to “Second Space”, and then “Turn on second space”.

Here a second space is created and the device is already quite ready for work. Nevertheless, after the reboot, everything will be reset and you will have to do everything again, so we continue. We go into the settings, then “About Phone”, “Additional Settings” and “Developer Menu (Developer)”. Move switch USB Debugging to the enable position.

We connect to the computer using USB and start Switch. Download “Minimal Adb and Fastboot” and turn it on. We go to the first desktop, and on the computer we type “adb devices”. Here we enter the following command: adb (introductory command) shell pm uninstall (parameters).k.user 0 (values) com.Xiaomi.finddevice (server connection);

Delete “Find my phone (Find my phone)”.

Nuances after such a decoupling.

After that, the gadget is ready for full operation: you can go online, use various programs, etc.

XIAOMI REDMI 9T NOT TURNING ON

However, it is worth noting that it will not be possible to use Xiaomi services. Which is explained by the absence of the account itself. There are a lot of complaints about the Xiaomi account from users due to poorly executed software, and it is quite logical that it is deleted.

There are many reasons for the disruption of the stable operation of the device. often problems arise against the background of everyday use. According to the masters and representatives of device manufacturers, power-on failures can be associated with the following events:

  • after updating the operating system, any system files were installed with errors;
  • the device stopped loading due to viruses that got in with applications not installed from the Play Market;
  • after falling on a hard surface, the display or battery cable is disconnected;
  • the USB connector is clogged or small but harmful rust spots have appeared on the contacts due to moisture.

Immediately it is worth noting: to cope with mechanical damage on your own is not easy. During home repairs, you can inadvertently break any connections, thereby making the smartphone unrepairable. If the methods proposed below do not give a positive result, then it is recommended to contact a trusted SC for diagnostics and repair.

Reset to factory settings

After the actions described above, several options for the development of events are possible. In addition to the usual reboot and power on, the phone may turn off again or hang on the splash screen. You should not be too upset because of this, because the manipulations done helped to make sure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor failures that resolved themselves. If the violation in the operating system is much more serious (for example, after a firmware with errors), then you will have to perform a factory reset. It is important to consider: during such actions, all files are deleted from the device’s memory, including photos, videos and music.

The device should go to reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Force restart Xiaomi Redmi 9T

First, let’s look at several methods related to recovery through Recovery mode. It will be possible to get into it if the gadget is charged by more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the operability of the USB connector.

So, if the phone responded to the charging connection, displayed the process of replenishing the battery, then after reaching a suitable level, you can proceed to the following manipulations:

  • Simultaneously hold down the power and volume up buttons. Hold them like this until the phone starts to vibrate. The boot screen will appear and it will be followed by vibration, then the power button can be released. Important: sometimes the combination with the volume down button works, not the volume up button.
  • In the menu that opens, select the item “Reboot to system” (in some versions – “Reboot system now”).

The device should immediately go to reboot, followed by a regular download of Android. By the way, if the gadget is not charging, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

Additional Methods

What to do if the methods described above did not help? The gadget suddenly turned off, stopped responding to pressing the power button or charging. with a high probability the problem lies in mechanical damage. If earlier it fell or fell into the water, then it makes sense to contact a service center for diagnostics. Another likely cause is a battery failure. The main symptom is a fast discharge from 100 to 0 percent until a malfunction is detected. For smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the case is solid, then it will not be possible to do without the intervention of masters.

NFC and wireless payments via Google Pay do not work on Xiaomi (Redmi): how to fix and configure

Xiaomi (Redmi) smartphone users use the NFC module for contactless payments through bank terminals. Most of the problems with NFC are related to the fact that it is impossible to make a purchase, while the person is at the checkout, most likely a queue has formed behind him, he is worried and does not know how to fix it and why NFC stopped working.

I will relieve you of this stress and show you the correct NFC settings on Xiaomi, which allows using the Google Pay service to pay for purchases in a second.

Make sure you’ve entered your valid credit card details in your Google Pay settings.

The instructions for setting up NFC were made on a Xiaomi Mi 9 SE phone with MIUI 11 firmware, if MIUI 10 is installed on your smartphone, the steps will change slightly, but in principle everything will remain the same, proceed in the same way and Google Pay will work for you.

Enter the general settings and find the “Connection and Sharing” item. Find the “NFC” item and activate it so that the module starts working. Now enter the “Security Element Location” menu.

You will see 2 options: “HCE Wallet” and “SIM Wallet”. It is usually recommended to choose HCE and indeed this option worked for me on the Mi 5 phone, but on the Mi 9 SIM mode is selected and Google Pay payments work fine.

Now enter the “Contactless payment” setting. Make sure the Google Pay app is selected in the Default Payment menu. Set the “Use default app” to “Always”. Next, we need to configure the program for payment, for this, select the “Applications” item in the general menu. Then click on “All Apps”. In the search bar, type “Pay” and as a result select the program from Google. Enter the “Other Permissions” menu. Make sure the “NFC” item is set to “Allow”. For persuasiveness, select the “Activity control” item, this is not necessary, but if the payments do not go through, it is worth checking it too. Select “No restrictions”. After the manipulations, restart Xiaomi and try to make a purchase, now NFC is working.

Batteries are constantly undergoing chemical reactions. If the energy generated by them is not enough to provide power to the control chip, then the closed circuit is automatically opened. The result is a deep discharge of the battery.

You can restore its performance if you connect your smartphone to the network for at least 3 hours. If the indicator flashes white on Xiaomi, and the device does not turn on during the charging process, then you should not try to turn on the device. After a few hours, unplug it and try turning it on again.

This is a rare malfunction, because the Android operating system works quite reliably. In this case, the Xiaomi indicator flashes white, but the device stops responding to user commands, the screen turns black, and calls and messages do not arrive.

  • “Work” of viruses and malicious applications.
  • Hanging of the Android OS, one or more system programs.
  • Incorrect firmware update, especially if a custom version was used.

It is recommended to reboot the device, for which the “Power” button is held for at least 10 seconds. It happens that the mobile device does not respond to such a command. Calling the service menu can help, for which the “Power” and “Volume Up” keys are simultaneously held down for about 15 seconds.

This usually leads to the appearance of the boot menu, where you need to click on the sub-item “Reboot” or “Reboot”.

If all actions did not bring the desired result, it is recommended to contact the service center.

It would seem that reverse charging is very convenient and practical. And as the developer promises us. quickly. But is it? Having figured out and tested this method, many users have identified enough disadvantages for themselves.

  • This way is slow. After testing, we managed to find out that only Samsung devices can quickly cope with the task.
  • This is uneconomical. A lot of energy is lost in the process, and at best half reaches the smartphone.
  • Inconvenience. No matter how the manufacturer assures, this is not practical. To charge the device, you must follow special rules, namely, the receiver must lie on the cover strictly within the coil. Accordingly, it will not work as a power bank on the go.
  • Unpredictability. Even having charged the gadget up to 100%, it can be discharged to 0 in a matter of seconds at any time.
  • On the market, the consumer is offered many options for untested devices that may not work properly, overheat and thereby harm the battery.

These shortcomings are considered objective and the rating was based on consumer complaints.

There are also positive aspects to this method.

  • To date, some public places are already available wireless charging, which can be used by anyone. This means that there is no need to carry the entire structure with you.
  • Some chargers are built into cases. The cost is several times more expensive, but it’s worth it.

Based on the foregoing, it is worth making a decision on your own. to use a similar method or to give preference to the standard one. In any case, it will be right to weigh all the pros and cons and come to a single decision.

Xiaomi Redmi phone does not turn on what to do?!

A telephone is a technically complex device consisting of many electronic parts, each of which is capable of failing at any time. This can happen with an expensive iPhone, and with a cheap Xiaomi, and with an old one, and with a new one, there is no difference. Let’s consider the case when suddenly, for no apparent reason, your Xiaomi Redmi smartphone does not turn on and the screen does not light up. When doing so, it may flash the red indicator. How to figure out what happened to him, is it possible to fix it yourself or still have to carry it to the service ?! In my opinion, in any case, you should try to determine the cause, even if you cannot fix it yourself, it will be easier to explain to the master in the service center what needs to be done with the phone.

How To Fix A Redmi 9T That Won’t Turn On

Main causes and their solution

I have been working with Xiaomi equipment for quite a long time and I want to note that the products of this company are quite high quality. At least not worse than competitors have successful models, there are not very successful ones. So, for example, many owners complain that Xiaomi Redmi 4x sometimes turns off on its own and the reason for these shutdowns is not clear. Therefore, I repeat, none of the models is immune from the mistakes of engineers and technical defects. If the device is still under warranty, then you can hope for a free repair or even replacement of the gadget. If you are faced with the fact that the Xiaomi phone does not turn on a few days after the purchase, then you can try to return it to the seller. But if you took it from your hands, then in this case you will have to repair it at your own expense.

Let’s look at the most common cases when Xiaomi Redmi turned off and does not turn on. Before that, you did not drown it and did not drop it. What to do? Starting with the battery.

Deep battery discharge

Modern smartphones use lithium batteries with a built-in charge controller that cuts off the battery’s electrical power line when fully discharged. This is done in order to protect the battery from a decrease in capacity below the permissible value, after which it simply stops working. That is why the phone does not turn on immediately when you connect the charger.

It is worth paying attention to whether the red charge indicator on the phone is blinking at this time (on some models it may be white). It is worth waiting at least 30-40 minutes and only after that try to press the power button. In some cases, to bring the device out of deep discharge, you have to wait several hours.

Faulty cable or charger

Many owners have a charging cable for about six months, after which they start acting weird. In addition, the length of the cable is not always enough and it is connected to the tension. Over time, damage appears, several times I even met cases when the plug came off and hung on thin wires, as on

Xiaomi chargers are of high quality and run for at least a year, but still fail sooner or later. At the same time, outwardly on it you will not find any traces, it just turned off and that’s it. And again, a person will assume that the phone is charging, but in fact it is not. As a result, when you try to turn it on, he will find that his Xiaomi Redmi does not turn on and does not respond to pressing the Power button. So the advice here is simple: if you have problems turning on your smartphone, try another charger and cable. Believe me, in 80% of cases the problem is solved at this stage!

Failed SIM card

Yes, imagine a regular SIM card can become source of phone problems. Therefore, I would advise you to remove it and try to turn on your Xiaomi without a SIM card. If the smartphone works, check the SIM card in another device. Her contacts can oxidize and this leads to a short circuit. If dirt, plaque or oxidation is visible to the naked eye, you can clean the contacts with an ordinary eraser or a cotton swab moistened with alcohol. If the phone does not turn on even without a SIM card, then it is worth checking the slot. True, for this the device will have to be disassembled. In my memory, there was a case when random debris bent the contacts in the slot and they closed.

Firmware issues

The reason for the problems with turning on Xiaomi phones can also be a software failure: unsuccessful flashing, failure during the loading of the operating system, installing TWRP, the result of malware. True, most often there may be some messages, icons on the screen. Then you should try to enter the engineering menu of the device by holding down the power button and the volume up button for more than 10 seconds. If you succeeded, then you can try resetting Xiaomi through the so-called Hard Reset.

When to go to the service center

If replacing the cable and charger did nothing and the Xiaomi Redmi smartphone does not turn on either in normal mode or in Recovery mode, you will still have to drag it to a service center. There they will already carry out a full diagnosis of the device and make their verdict. Among the common hardware problems, I can name such a frequent phenomenon as damage to the cable with the power connector. It burns out itself or the power connector and the smartphone does not charge. Replacing it is not so difficult, but if there is no experience, it is better to contact professionals.

Battery is deeply discharged

Almost all modern Xiaomi and Redmi smartphones are equipped with fast charging and capacious batteries.

If the Xiaomi phone has run out of battery and has not been charged for a long time, the controller is activated, which blocks the battery power line so that it does not fail. In this case, you need to either leave the phone to charge for a long time, or connect it to a more powerful charger.

What to do if Xiaomi phone does not turn on after downloading the update

Management in Recovery mode on Xiaomi smartphones.

Sometimes after downloading additional applications, such as TWRP, a Xiaomi or Redmi smartphone may not respond to actions.

  • If Xiaomi does not turn on and you suspect that the problem is related to one of your files, you can reset the data through the Recovery mode: select the Wipe Data Yes button on the screen. However, this will delete all information on the device. be prepared for the consequences.
  • If the phone turns on and even the screen wakes up, but the download stops or the device stops working quickly, then the problem may be in the operating system. Then it is enough to reflash the phone. This can be easily done through Mi Flash Pro.
  • If the Xiaomi logo is stuck on the screen, press the volume and power buttons, release as soon as the phone vibrates.

Xiaomi phone freezes, screen does not turn on

If the phone does not respond to your actions, does not turn off, and the screen is inactive, try restarting it first. On different models, this is done in its own way, but most often by holding down the power key (sometimes with the volume down button) for a few seconds. If this works, you will enter FastBoot mode, which is similar to the BIOS on a PC. In it, select the Power button to restart the OS.

If there is no result, it can be assumed that the error is in one or more system files. It’s too early to despair, you can try to reflash the device or roll back the operating system. You can do this in several ways:

  • Download the old version of the MIUI interface, but this will only work if the bootloader is unlocked
  • If your phone is in developer mode, then the system can be rolled back
  • You can also download new software in Soft Recovery mode

In older phones, this problem is sometimes solved like this: you need to remove the battery and insert it back. However, modern smartphones have a one-piece design, so you will have to contact a repair center to solve the problem.

Why Xiaomi phone won’t turn on

The reasons can be completely different, but there are some of the most common options:

  • discharged battery;
  • the operating system freezes;
  • the power button does not work;
  • any structural element has broken;
  • the phone has been dropped into water or liquid has been spilled on it;
  • phone has been damaged.

First of all, find out which of these reasons is most likely. maybe you dropped your phone or updated it. If the device is new, marriage is possible. In some cases, you will be able to fix the phone yourself, in others, you will have to send it in for repair.

Xiaomi stopped turning on after falling into water

Not all Xiaomi and Redmi smartphones come with water resistance, but they are often more durable than they seem. If you drop your phone in water and it stops turning on, dry it first. Many people recommend putting the device in a bag of rice, as the rice draws out moisture. After that, try turning your phone back on. If it does not work, then it must be taken to the repair service.

Important: never dry the device near batteries or radiators!

What to do if Xiaomi phone does not turn on

What if the Xiaomi smartphone has turned into a “brick”: it has stopped turning on or simply does not respond to actions? You can immediately run in a panic to a service center, but first it’s better to try to figure out what’s wrong on your own. We will tell you how you can find out the reason why your phone stopped working and fix it.

Xiaomi phone does not turn on but the indicator light is flashing

On different smartphones, the location of the indicator is different. Mi 9T has it on the top sidebar.

A red indicator light may indicate mechanical damage or system errors. To resuscitate the phone, users advise this method: first, simultaneously hold down both volume controls and wait for the phone to vibrate, then press the power button.

If this does not help, it may turn out that the problem is with the cable, the power button, or the power module. This often happens when the phone is dropped or hit. The mechanisms inside are sensitive and damaged by such incidents.

In this case, the problem is solved in the service center. It is not worth disassembling the phone yourself if you are not sure what you are doing. Also remember that attempting an uncertified repair will void your device warranty.
