Phone won't boot after factory reset. How to reset Android settings

On the Internet, you can often find messages from the owners of android devices, telling about how users unsuccessfully played with the gadget settings and what came of it all. In most such cases, it is recommended to reset all parameters to the so-called factory settings. However, it may happen that after such a reset, the android simply stops turning on.

Android does not turn on

If after resetting the settings, the android does not turn on, you should not immediately run to the service, since in some cases, the problem can be solved on its own. There are quite a few reasons why, in view of what, it is required to check all possible ones in order to exclude erroneous diagnostics.

First, you should try to connect the charger and look at the reaction from the gadget. We must not forget that many modern devices have an unpleasant feature - when fully discharged, they do not respond to charging connection for some time, which means that you need to wait at least half an hour.

If you were reset through the usual android interface, and not through code or system flashing, you can try using a deeper reset. To do this, you need to find out and type on the device special code reset, the input of which will lead to a complete loss of all data, but the device will be able to turn on.

Difficult situations

However, all of the above methods may not give the desired effect, which will lead to the need to reflash the device. This operation should be performed independently only in cases where the user is firmly confident in his skills and abilities to carry it out. Otherwise, it is better to provide an opportunity for specialists to look at the gadget so that they can quickly fix existing problems.

During the flashing, it is extremely important:

• Provide access to the gadget for charging in order to exclude the possibility of emergency shutdown or disconnection during the firmware process;
• Monitor the stability of the connection between a computer and an android smartphone or tablet;
• Use the recommendations of the device manufacturer in the process of performing manipulations.

Only by observing the above rules, you can count on a positive outcome of the flashing. If it is carried out incorrectly, then all the efforts of the user will be wasted and you will have to start the procedure from the very beginning.

What to do if android won't start. Causes and their elimination

Everyone should know what to do if Android won't start. All the methods suggested below do not require additional technical knowledge and cannot harm the operating system or the device itself.

The Android operating system is not only the most popular in the world, but also very simple, convenient and reliable. Nevertheless, any modern device sooner or later fails or begins to work not quite correctly. Such an unfortunate incident is upsetting and can spoil the nerves in order. There are times when the problem is serious and only a specialist can help. But before you go to service center, it is worth trying a few simple tricks that can completely revive the smartphone.

Battery or charger

It may sound trite, but more than half of the problems with turning on an android are related to the battery or charger. This is not about the fact that you just forgot to charge your phone, but about more global reasons.

With a long and active use of the smartphone, its battery gradually wears out. There comes a moment when it is discharged to such an extent that an ordinary network adapter can no longer help her.

If your phone is old and collapsible, remove the battery and use the frog tool. This is a charger that provides a more powerful charge and can save your phone for a while.

Owners of one-piece and non-separable models at home should not experiment. If you suspect that the battery may have failed, contact a service center to have it replaced.

A charging AC adapter may also be causing the problem. New chargers may not be original or compatible with this smartphone. This means that the battery does not receive energy during charging, and the android simply cannot start. In old chargers, contacts leave, wires break, etc. Therefore, it makes sense to try to charge the phone from another adapter.

Hardware problems (phone freeze)

It may happen that the phone is not turned off at all, but "freezes" with the screen off. It is worth figuring out what to do if the android does not start due to freezing.

All procedures will be aimed at maximum activation and restart of the device.

If the phone has a removable cover, take out the battery for a couple of minutes, then replace it and turn on the device. Such simple manipulation often gives good results and returns the smartphone to normal operation.

With more modern models the situation is a little different, but there is nothing complicated here either.

If, after a standard single press of the power off or lock button, the phone does not turn on, hold down this button for 10-15 seconds. After that, the screen may light up and the phone will continue to work.

The second way to reboot will be the so-called " forced reboot". To do this, you need to find the reset button and gently clamp it with a needle, paper clip or toothpick. In all models, it is located in different places, but it looks almost the same. If you can't find the reset button, open the instructions for your phone.

There is another simple method that can wake up the phone. Connect it to your computer via USB. By detecting a new connected device or power source, the smartphone can wake up from its sleep mode.

Software malfunctions

If none of the above methods helped, the last chance to turn on the phone yourself will be full reset settings (in technical circles it is called hard reset).

There are several ways and options here too.

To begin with, consider the situation when the phone still turns on, but it does not work correctly and the android constantly hangs.

When you return to the factory settings, absolutely all information will be deleted and the phone will become just like new. Therefore, if possible, it is imperative to back up all data. New models in their menu already have such a function as "data backup", "backups", and then full recovery data. Information can be copied to any existing account, google drive or cloud.

Photo: Backup on the phone

It is also possible to copy all data to a PC or laptop using USB cable or, for example, the Share it program (Download). It is worth remembering that contacts from the phone book will be saved in one of the folders as a .vcf file.

To reset the settings, go to "Settings", select "Privacy" (if the version is Android 2.2 or lower), and then "Reset settings". V latest versions go to "Settings", select "Restore and reset" or "Backup and reset", then click on "Reset", "Reset settings", "Reset tablet PC" or "General reset".

When the phone is turned off, and it is not possible to turn it on, you must simultaneously hold down the volume up button and the off button (on some models, the volume button, home button and off). The Recovery technical menu should appear on the screen. You need to select the line wipe data / factory reset (down-up control is carried out using the volume key). Then click on Yes, delete all user data.

Do not forget that for full rollback to factory settings, you need to clear all cache and SD card. To do this, you can go to "settings", "memory", "clear SD" or clear immediately upon reset by clicking on the wipe cache partition.

Important nuances of factory reset

There are some very simple ones, but important rules that must be observed. For example, during all operations with a smartphone, it must always be connected to a charger. Then the phone will not turn off at the very important point messing up the whole setup process.

If you plan to do a factory reset in advance, you need to overclock your device's battery. To do this, first discharge it before turning it off, and then fully charge it. This will ensure that the battery.sys file works properly.

Since all phones are very different in Android interface and firmware, some users experience certain difficulties during the procedure. Do not worry, be calm and read every name of the menu very carefully. If the smartphone model is very new or rare, it is better to study the instructions for it or go to the official website.

Problems after a factory reset

Unfortunately, it is quite possible that the android will not turn on after a factory reset. You should again hold down the already familiar volume up, shutdown and "Home" buttons and hold for 10 seconds. The Recovery mode menu will appear, select the "wipe" item, confirm our decision by pressing the Home button.

In a collapsible phone, remove the battery, underneath there is a factory reset button. After pressing it, the factory reset will be repeated and the phone will turn on.

If the advice did not help, be sure to contact the service center for flashing software.

conclusions

The listed tips are safe and effective enough. In most cases, they can be used to return the smartphone to normal and correct operation. You do not need to puzzle for a long time over what to do if the android does not start for one of the reasons. In the event that home diagnostics did not give a positive result, you need to contact the professionals. The cause of the failure can be serious, such as completely faulty software, problems with the die, or other internal damage.

Android phone won't turn on - what should I do? Solution:

V modern world it is impossible to imagine a person's life without a telephone. Every person has this little helper. It allows you to easily contact the desired subscriber. But imagine that your Android phone does not turn on. What to do in this case? Of course, it will be quite difficult without a smartphone. If you do not have a spare gadget, then you need to quickly fix your device. In this article we will look at why the Android phone does not turn on.

Mobile check

If the phone stops turning on, then you should not immediately disassemble it and see what could have happened there. Of course, if you do not have certain knowledge, all these actions can be detrimental to the smartphone. Subsequently, repairs can only become more complex and costly. Why won't the Android phone turn on? What to do in this case?

Before proceeding with drastic actions, you need to check - maybe it did not break at all. First you need to find out if the battery is charged, or maybe the reason is software glitch apparatus.

Mobile device battery check

As we have already found out, the phone may not turn on due to low battery power. We put the smartphone on charge and wait about 30 minutes. After that, we try to turn it on. If the phone was able to "revive", then the problem is high power consumption. How can this be fixed? It is enough to turn off Bluetooth and Wi-Fi after use. These elements are constantly working to find a possible network in order to inform the user about it. If you turn off these elements, you can save a charge for a longer period. You should also decrease the brightness on your smartphone, as a bright screen consumes a lot of energy.

If you have a function on your mobile phone that allows you to change the brightness automatically, based on the illumination of the room, then you should turn it on. Let's get back to the problem. If the phone can be turned on when it is charging, then let it stand for about 4 hours. It's worth checking the battery expiration date - it might be time to replace that component. If the phone does not turn on, but Android is charging, you need to consider other possible situations.

Smartphone power button

The phone may flash but will not turn on. This may be due to a malfunction of the power button. The reasons why it may not work can be different:

• If you have just purchased mobile phone, and it does not turn on, the power button may be faulty, and the reason lies in the factory defect. What to do in this case? You need to go to the store where you purchased the smartphone and ask for a refund, replace the phone or have it repaired. The seller is obliged to do something in this case.

• Another reason is also possible, which is already associated with your inaccuracy. If you spill liquid on your mobile device or drop it, there may be various reasons why the phone will not turn on. In this case, do not disassemble the device yourself. Of course, if you have a guarantee, you can try contacting the service center. Otherwise, you will also have to resort to the help of a professional. Unfortunately, even he is not capable of fixing any phone.

Memory card

So, your Android phone won't turn on. What to do? The reason may lie in the SD card. Your phone may not support a certain memory card, which may cause your mobile device to freeze or not turn on at all. You should choose a memory card in specialized stores, having previously learned that it will fit your smartphone. If different memory cards cause the same effect, then the problem is with the phone. In this case, you need to reflash the mobile device. You can do this yourself, but you should be careful, as you can only harm.

Phone won't turn on after Android update

Sometimes there are situations with smartphones when it does not turn on after an update. As a rule, new gadgets are more prone to this. Various updates come to the mobile device, which, unfortunately, are not secure. This is usually the case for smartphones that have constant access to the Internet. After such updates, the phone may turn off arbitrarily and turn on after a while.

Another situation is also possible: you try to turn on your phone, and there the Android inscription lights up and nothing else happens. Reboots bring the phone back to this problem again. So, your Android phone won't turn on again. What to do? In this case, it is worth trying to turn off the device and stick out the battery for a few minutes, then turn it on and reset the settings. If the problem was not serious, then you will succeed, and after a while the phone will return to its previous state.

If he refuses to work adequately, then you should use a hard reset. This will clean your phone from updates and all information. But, most likely, it will return to working condition. Of course, all your personal information will disappear, but returning your phone to its former life will probably be more important. This reset will be done differently for each smartphone. You need to find suitable way for your model. Phone won't turn on after factory reset? Unfortunately, this solution may not suit Android. In this case, you will need to reflash your device.

The phone does not turn on after the firmware ("Android")

If you unsuccessfully reflash your device, then it may not turn on or hang on the Android logo. What to do in this case? Of course, you will have to reflash again.

First, we go to the manufacturer's website and look for the necessary firmware that will fit your model. You should not search for firmware through a search engine, as it will give out many different programs that most likely will not work. So you can only aggravate the problem and bring your smartphone to a state of "brick".

The phone does not turn on after flashing. "Android" can still be brought back to life. You will need to install correctly new firmware... If you do not know how to do this, then you need to contact the service center. This way you can be sure that everything will be fine with your phone.

Mechanical damage

The most common cause of smartphone breakdown is mechanical damage. If the phone falls, or you spill liquid on it, then this is already a serious problem that cannot be easily dealt with.

If the fall was not serious, then you can try to stick out the battery, SIM card, SD card. After a while, we return everything to its place. If the phone is working, then you are in luck, and it just lost contacts. Otherwise, the problem is more serious. If you do not have the necessary knowledge, then you should not try to disassemble and repair a mobile device yourself. In this case, contact the service center.

Turning on your Android phone in case of problems

Even modern gadgets at a high level of technology development, they can fail. There are often times when your smartphone simply does not want to turn on. Many people fall into a stupor, and do not even know what to do if the phone does not turn on. We will give the most common reasons for this breakdown, as well as possible methods solutions.

In most cases, the problem is related to the battery of the gadget. A less common option is operating system problems. Before taking your device to a service center and preparing money for repairs, we recommend that you take several independent steps to identify the malfunction. The problem can be trivial, which you can solve without outside help.

Battery faults

There are several reasons why the phone won't turn on. Perhaps the battery has simply run out, and charging does not have any effect. This is the most common problem, but there may be several reasons for this:

• Dirty charging socket. Modern phones are charged via microUSB. A layer of dust can clog the contacts, so the charge will not flow into the smartphone. We recommend that you unplug the device and then carefully use a needle to remove all dust and dirt from the connector.

• Another reason why "Android" does not turn on is the power button is broken. If you have new smartphone then it could be a marriage. Then carry it back and change it to a new one. Otherwise, you will have to go to the workshop, where you will have to replace the button for money, if the problem is really in it.
• The worst case scenario is that the power controller burned out on the phone. It is he who is responsible for the process of charging the gadget. The only way out is to take the phone to a service center and then replace it.

As you can see, users can solve most of the problems on their own if the phone does not turn on. To extend the life of the battery, do not often discharge the gadget to full zero, but use only certified chargers from the manufacturer.

Memory card

The problem may be that you inserted an SD card into the gadget that the smartphone does not support. This can lead to failures in program code and the impossibility of inclusion. How do I turn on the gadget? Just pop out the wrong memory card. If it still won't activate, you may need to reflash your smartphone.

Always read in the specification which memory cards and up to what capacity your device supports. mobile device... You can also get advice from the sellers of mobile stores.

Incorrect system update

Some smartphones, after updating to a more recent firmware, turn into a brick that will no longer be turned on in the usual way. The solution may be to roll back to factory settings. This can be done with Recovery Mode. To enter it, follow these steps:

1. Hold down the Volume Up key.
2. Without releasing it, hold down the Home key.
3. Simultaneously press the third button "Power on".

On some smartphones, the transition is carried out by pressing "+ .- volume" and the "Power on" button. Using the volume keys, you need to move the slider to the line "Wipe data / factory reset", and then confirm your choice by clicking "Yes - delete all user data".

You will be able to clear the cash and data section. But be careful, as all personal data (photos, contacts, videos and apps) will be lost. If there is something important on your phone, contact a service center.

Resetting to factory settings is relevant if the phone's loading hangs on the icon with the "Android" image. This also speaks of incorrect work microprograms. On some devices, to restart the smartphone there is a special button that can only be pressed with a needle or toothpick.

Viruses

If the phone does not boot, the operating system files may have been corrupted by some kind of virus. Here you will need to rewrite the phone. In some service centers, specialists will be able to restore the phone's functionality by cleaning it from viruses. To avoid such situations, we recommend downloading applications only from the official Play Market store, as well as installing an antivirus. You can choose ESET or Dr.Web for mobile devices.

Screen breakage

In fact, your gadget may turn on, but you will not know about it, since the screen will not show anything. If it does not turn on, there may be several reasons:

• loop failure;
• water entering the structure;
• the display is out of order.

Try calling your smartphone. If you hear a signal, but nothing appears on the screen, then the reason is really in it.

Hello everyone. Today I would like to analyze all the most common reasons why an Android smartphone may not turn on. I will not touch upon those situations when it is required to disassemble the phone and intervene in the electronic filling, since this is the work of completely different specialists.

If your smartphone or tablet suddenly stops turning on, it is not necessary to immediately run to a service center or workshop and send it in for repair. Most likely, there is a chance that you can do it yourself and save some amount (programs for home bookkeeping on Android will also help you in saving, look for them on the blog). Below we will consider the main measures that can be taken if an Android smartphone or tablet does not turn on. And so, let's get started.

The Android phone does not turn on. 5 ways to solve the problem.

Method number 1

From my own experience, I will say that in 80% of all cases, if they come to me with a problem that the phone does not turn on, the whole thing turns out to be in a discharged battery. And I perfectly understand when they tell me that they have been charging the smartphone all day, but it still does not turn on. Some devices have one unpleasant feature- if the battery is discharged too much, it will not charge, even if you keep it on charge all day.

In this case, a frog-type charger will help us, which allows you to charge almost any battery directly by removing it from the phone. It is enough to recharge the battery in this way for 15 minutes. Then insert it back and put the phone on charge as usual, everything should be OK.

If getting a frog is problematic for you, then you can use any old mobile phone charger. Cut off the old plug and protect the wires.

Make sure that the charger is not plugged into an outlet at this time.

We fix the bare wires on the battery with tape for a few minutes.

Important. Do not mix up the polarity.

Method number 2

Faulty charging. Of course, the second thing to check is serviceability. charger... Everything is simple here - we take a working charger and try to charge our smartphone. If the process has started, then we buy a new one and rejoice. Although it sounds trite, it helps one in five.

Method number 3

If the phone does not turn on, then it may simply be frozen. To revive your device, we will apply a long-known, but still relevant method - take out the battery and insert it again.

Unfortunately, this trick does not work on many modern phones with a non-removable battery. In this case, to reboot, you need to find the reset button and press it with a paper clip, for example. It can be anywhere, but it is usually located near the SIM card slot or on the back of a smartphone or tablet. There is sometimes an inscription “reset” or “off” near the reset button. The photo below is an example of the location of such a button in a smartphone.

Method number 4

This method is applicable if your phone does not really turn on, but does not turn on completely. For example, it hangs on your Android logo and nothing else happens. This happens due to a malfunction in the smartphone software. Then hard reset will help us or, in translation, hard reset... For each model of the device, it is made in different ways. To find out how, enter the name of your phone and the words hard reset, for example LG G3 hard reset, in Google or Yandex and follow the instructions. In the future, I hope to create on the blog separate section on this topic.

Unfortunately, not all smartphones support hard reset, it depends on the recovery installed in the device. If you are interested in learning more about what it is, look on the Internet.

For example, there is no such function by default, in many sony phones, but the manufacturer has provided the ability to restore the software using special utility Sony pc companion.

Method number 5

Not often, but it still happens that smartphone does not turn on due to the fact that the contacts under the battery do not reach. To fix this, you need to bend the contacts with tweezers or a small screwdriver to improve the connection with the battery. The main thing here is without fanaticism, otherwise you will only make it even worse.

If none of the methods helped and your phone still does not turn on, then the problem most likely lies in the hardware itself and only the service center can help you.
