Users of modern devices have become accustomed to useful function rollback phone to factory settings. This helps to resolve most software problems or correct adjustments made to the machine's settings. It rarely happens that after a factory reset, the phone does not turn on. Why this could happen and how to solve the problem, we will learn further.

We already that hard reset does not always help to return the phone to its original state, but, on the contrary, worsens an already distressed situation. After an unsuccessful rollback, you can observe that the android does not start, it remains dark screen or a reboot occurs. That is, the device is able to show signs of life, but is not able to boot the OS.

In this case, users are divided into three conditional groups: the first do not understand what to do if the android is out of order, the second run to service center, and the latter decide to reflash the device on their own. The last option is the most dangerous, because from ignorance of the cause of the breakdown, the phone can turn into a “brick” with no chance of recovery.

Solution

1. Try to reboot.
2. Take out the battery for 20 minutes.
3. Pull out the memory card and SIM card.
4. Leave the smartphone on charge for at least 3 hours.
5. Try flashing Android.
6. Give it to the workshop.

Software malfunctions

The main reason why the phone does not work after a hard reset is a failure in the operating system. It could appear due to the installation of unverified applications on the device from an unprotected source. Don't drop the option failed update OS, when at the time of its installation, the device was accidentally turned off or the battery ran out.

Attempts to return the gadget to service fail and the phone stops turning on. In this situation, only the firmware of the device can really help. Together with it, all software failures will be deleted from the device’s memory, and the owner will receive a clean system.

It is worth mentioning the android owners who independently installed the incorrect firmware for themselves, which can also become a reason to refuse to boot the Android OS after a hard reset.

A nuance can be a factory reset through the gadget interface. Perhaps the problem can be solved through a deeper reset operating system, which are performed by entering a special code for a specific firmware version or gadget model.

If you still managed to turn on the device, check it for possible viruses that can hinder the operation of the software. Also, programs may be required to check the integrity of the internal memory. Due to its damage, unforeseen malfunctions occur that cannot be determined without a thorough diagnosis.

Important nuances of resetting settings

Anyone considering a rollback should keep a few rules in mind to keep their Android device running.

1. Before making a hard reset, prepare the charger. If the battery runs out at the time of the system rollback, harm will be done software. It has already been said earlier that in this case, only the firmware of the device can correct the situation.
2. Even with a charger on hand, it’s better not to risk it and fully charge the battery. This advice is especially relevant for those who chose the usb connector on a PC or laptop as a power source. It is not able to provide the required voltage, which is why the gadget will not be able to make up for the full amount of energy expended and will simply turn off.
3. Do not forget that when resetting the settings, all files in the internal memory are deleted. To avoid trouble, the information can be copied to cloud storage, to a memory card or PC.
4. Users who do this for the first time should follow the system rollback instructions provided by their device manufacturer. This will avoid difficulties with the operation and the loss of important contacts.
5. If you notice that the battery behaves inadequately, independently replenishes the energy spent or sits down even when charging, it is better not to risk it and postpone the reset until you get a new battery.

Conclusion

Modern devices may have problems even after a full system rollback to the factory state. To avoid most of the malfunctions, you need to carefully study the above rules.

There may be several reasons why the phone refuses to boot: hardware failure or software malfunction. If a hard reset did not help you, you should not try to repair the device yourself. In a distress situation, if the phone does not turn on, the best way to solve the problem, there will be a visit to the service center, where professionals will deal with it.

The development of the android system, one of the main tasks Google. Among the many new features, we want to tell you about new program protection that appeared on all Android phones with version 5.1 and higher. Thanks to her, for example, if the phone is lost or stolen, the owner of the device has the opportunity to block it. Thus, no one will be able to download the phone without knowing the login and password from your account in . It will also work when resetting the phone settings (hard reset).

This feature is called Google Factory Reset Protection, abbreviated as FRP lock.

A similar security scheme has been implemented for a long time by Apple in their products and has not proven itself badly. Here's what happens if you do (for example, when you delete a pattern or phone firmware). When you first start and check access to wifi networks, the phone will ask verify account. A similar inscription will appear.

Of course, if you remember the necessary data (they are entered when buying a phone), login and password, there will be no problems. But here's how to bypass Google account verification if you forgot all your personal data and there is no way to restore them through email, and the firmware does not help?

There are several ways which one is right for you, I can’t say, since each of the phone manufacturers (Samsung, Micromax and others) release models with their own individual features - various function keys and software stuffing.

• Reset system settings and removal of DRM license without cable.

To do this, we need to get into the phone settings by bypassing the standard boot through the help system. See in the video step by step instructions on the example of a Lenovo phone.

• Soft reset via app.

Here the procedure is more complicated. To do this, we need an OTG cable with a program downloaded to the flash card, or simply reset the application (StartSettings.apk) to the Micro SD and insert it into the device. Similar in the video on the example of a ZTE phone.

• Other non-standard methods.

Due to the huge number of models, there is no single correct solution to this problem. For example, in this video, the author turned off the modem with Internet access during the check and was able to bypass the confirmation on the LG G4 phone.

Maximum full list all non-standard methods are presented.

I hope that with the help of our material you managed to untie the phone from your Google account. If you have any questions, write them in the comments

Many of you leave your options for bypassing protection. We want to share one of them. This method was used on a Huawei MediaPad T3 7 tablet.

1- Charge your tablet to 100%
2- Turn on, select the language, region and connect to Wi Fi by accepting the terms of use.
3- On the next page " Google Services"We poke on the blue inscription" Google Privacy Policy "and in the window that appears, click and hold on any of the words so that an additional menu appears in which there is" Web search ". Click on it and select Opera (namely opera, because it may not be possible to open downloaded files in chrome).
4- Download Test+DPC. I had version 4 (as an option, use other programs quickshortcutmaker and Google Account Manager). I don’t know how anyone downloads, but I went to my Yahoo mail, where in incoming messages I sent myself from another mail desired file. Install, run. Select the second item "set up device owner", encrypt the device. Although in many videos seen choose the first one. I haven't personally tried it. A reboot is in progress. Several times further, and then the DPC window pops up with a suggestion to configure the profile. We accept the agreement. Customizable. Then some kind of tablet will endlessly pop up (I don’t remember which one, there’s no tablet at hand already). Reboot.
5- By clicking next, it should start (if the DPC menu pops up with a suggestion in English to create a profile, select the lower value "skip".
6- Everything, the tablet is running in normal mode. Go to settings and do full reset. After turning on, we rejoice at the unlocked device

Also in the commentary and private messages they ask in the Google system. We have a separate article about this. Here we are discussing something a little different, namely possible ways confirmation bypass.

We will supplement the material with another video from the visitor. This method is useful to all owners Xiaomi phones, regardless of the model.

A factory reset deletes all data from your phone's internal memory. These are photos, videos, music, applications - everything that was recorded during use mobile device. In this case, the sd-card will remain untouched: the files on it will be saved after a hard reset.

5. Tell me, please, is it possible to return the photo if we took pictures and the photos were not saved, they were just in the "camera". The child forgot the password on the phone and just took and reset the settings through the hardware buttons. Can we return the photo?

Answer. Yes, you can, but the likelihood of recovery depends on your perseverance and the time that has passed since resetting Android. You can use the recovery method described above (through creating an image of the internal memory).

To search for photos in a mounted disk image, you can use any, even free software, like PhotoRec or Recuva (turn on the deep scan option). How to use them, see this video:

How to restore phone numbers after a factory reset

1. If you did not set up contact synchronization before hard reset, this guide will help you recover deleted contacts and phone numbers after a reset.
2. If contact synchronization has been enabled (for example, via Gmail), connect your Google account and wait for the contact list to be synchronized.
3. Check if there is a VCF file on the memory card or in the phone's internal memory.

How to restore applications

After resetting the settings, Instagram and another program are not installed. What can I do to install applications?

Answer. Restoring applications after a hard reset is usually straightforward.

Some Android apps require a newer version of the OS on your phone. After a hard reset, you roll back the version of Android to the one that was installed by the vendor. Therefore, for good, you need to download Latest updates phone firmware. You can do this through the settings.

To reinstall all applications, just connect Google account user. Applications will be downloaded and installed on your phone automatically - in their latest version.

What to do if the phone does not work after a hard reset

1. I have a phone HTC One V, and after the reset, the phone stopped working. The screen turns on, the HTC logo appears, and nothing else happens. What to do?
2. Clicked on reset to factory settings. Now the phone says Secure Fail: Recovery and a yellow triangle. inside black Exclamation point and again neither here nor there. The phone does not turn on for a long time, what should I do?

Answer.

Method 1. Perform a factory reset again - with the removal of all data from the internal memory of the phone.

Since you do not have access to the Android OS, you can do a hard reset through the hardware buttons. For this:

1. Remove the battery and put it back in the phone
2. Press and hold the volume up button
3. In addition to this, press and hold the power button

Then you will enter the recovery mode to factory settings.

Note. The hard reset method is different on many android devices. See the manual for your smartphone for details.

Method 2. If repeated hard reset does not help, install an alternative - unofficial - firmware. We advise you to look for instructions on the w3bsit3-dns.com forum.

Lost access to account after factory reset

1. Lost phone. When they returned, I realized that they tried to reset the settings, but could not, because the Google Account interfered. How can I now log in to the phone, given that I do not remember either the password or the login?
2. I accidentally reset my phone and lost my Google account. I tried to restore it, but it popped up: insufficient evidence. What should I do?

Answer. The problem is solved quite simply. You need to go to this Google page and answer the questions. If the account belonged to you and at the same time you had recovery data (for example, a backup Email or phone number), you will be able to restore access and "link" the account to the mobile device again.

Restoring filenames

I had a problem with the phone: if someone called while using it, a message appeared that the Phone application was stopped. I asked on the forum and they said that you need to reset the phone settings. After the reset, the problem was solved, but it turns out that the music was in the phone's memory. Is it possible to restore it or at least find out what kind of music it was?

Answer. You can't restore music. Find out the names of the files - yes, but only if they are stored in the file table. To do this, use the method of recovery from internal memory, which we described in this guide. This procedure is rather complicated and time consuming.

Phone memory full

I had an automatic factory reset on my tablet with Android v4.0.3. After that, I can’t download the application, writes: internal memory is full, free up space. But the memory is clear. What should I do?

Answer. Although a Hard Reset deletes user data, the phone's memory is not completely cleared - unless you have specified the appropriate item in the menu.

Try manually deleting the files. The most convenient way to do this is through the Root Explorer file manager or the Storage Analyzer utility for Android.

Internet not working when setting up phone

1. I forgot the password to unlock my Samsung Galaxy A3 2016 phone. After resetting to factory settings and after the greeting, only the search for a Wi-Fi connection is turned on, the "Next" button does not work. What to do?
2. I recently did a factory reset. Everything was fine, I turned on the phone, chose the language, connected to the Internet, then the "connection test" download went on. This download is already worth the second day, I don't know what to do.

Answer.

1. Try setting up your phone via a different wifi network (maybe the problem is with the wifi router).

2. Enable usb debugging on your phone 3. Download and install custom Android firmware for your device (rather unsafe method, only suitable for advanced users!)

Phone notes deleted after reset

Restored factory settings on Android, but forgot to transfer phone notes to another phone. What to do in this case? Is there any way to recover text notes?

Answer. If you previously stored text notes in the standard Google notepad application, recovery is unlikely: after a hard reset, all application settings are deleted.

However, if you set up a sync with Samsung Cloud, you can easily restore your notes in the Samsung Notes app by re-syncing them to your account.

Answers to other questions

Please ask any questions about recovery after Hard reset, through the form feedback. We kindly request: formulate the question in detail and preferably without errors.

Did encryption, failed. There was nothing left to do but press the "reset" button. But before the reset, I had a bunch of photos, there are photos of my parents, travels, etc. I really need these photos, I’m already in hysterics and I don’t know how to continue to live when your whole life was on your smartphone.

I accidentally screwed the android to the factory settings, i.e. reset, respectively, all the photos were deleted, can I restore them using the application and which one?

Answer. After a factory reset, all data in your phone's internal memory was deleted, including photos. There are two ways to solve your problem.

1. Look for photos on the memory card, on the Internet (if you have stored backups there).
2. To recover data in the internal memory, we recommend a simple program DiskDigger for Android. You can download it at Google Play..

My friend caught a lock virus on a Microlab phone. Naturally, no one wanted to pay hackers to unlock it. I reset the phone to him completely and now the language selection screen appears and after searching for Wi-Fi. It doesn't go further. Inserted SIM cards, still does not let go further. What happened to him now and how to fix it?

Answer. So, the problem is that the phone cannot connect to the wifi network. Find a network with open access and try to connect. If it doesn’t work anyway, change the firmware to custom.

On the phone (samsung a5) the glass was replaced and the phone was reset, photos and videos disappeared. Is it possible to recover and how? Tried through your program - it did not work.

Answer. Curious to know what recovery programs you used. The question also arises, where did you look for the deleted data - in the internal memory or on the sd card. As it was written above, a factory reset erases internal memory, so you will need utilities like DiskDigger for Android. Another recovery method is through creating a snapshot of internal memory and then searching for files on it.

Android 5.1 Lenovo A2010. I wanted to update, but I clicked on the factory settings and all the necessary photos and videos disappeared. I downloaded the Tenorshare Data Recovery program, but I can't open it, i.e. does not open on the phone. What to do to restore deleted photos and video?

Answer. Really. tenorshare program Data Recovery runs only from a computer. It is not a fact that with its help you will be able to return data after a hard reset (that is, reset to factory settings). You need a way to recover from internal memory. See answers above where we answered a similar question.

I made a hard reset on the lg D724 phone, after synchronizing everything. But I missed the most important thing - notes from the notepad application. The wife had a lot of important information in a notebook. Can you please tell me how to restore it?

Answer. Try the EaseUS MobiSaver program. We have not tested, but the developers claim that MobiSaver can recover notes. However, it is important to note that after a hard reset, the internal memory is erased, and not all applications can work with it. So, to be honest, there is very little chance of getting back text notes after a reset.

I have samsung galaxy s7 edge. The problem is that when I entered the camera, she gave me such a notification "Warning camera error", after which every time I enter the camera the phone gives such an error. I reset the phone to factory settings, but it did not help ... clearing the cache in the camera settings and reset her data, but all my efforts were even, nothing helped.I went to the service center, they said that they did not have the equipment to disassemble and see what was wrong with the phone, and in return they could send it to Moscow for repair, but it will take weeks or more I don't need it Is it possible that if I roll back the phone to previous version OS, that is, on 6.0, since I have 7.0. Or just reflash the phone. Tell me if it helps? If not, then help and tell me a couple of ways to fix this error.

Answer. Go into Android safe mode and check if the camera is working. This will help to determine if additional applications installed by you or with the firmware affect the camera.

Perhaps you are using custom firmware - if so, we advise you to find alternative versions or flash your phone to the official firmware.

If resetting to factory settings really didn’t help, you need to contact a Samsung service center or, as you mentioned, send it to Moscow for repair.

Phone reset to factory settings, how to recover data from phone? Tried through applications from Google Play, almost all of them require root. What is it and how to get it?

Answer. Root access (or superuser rights) gives recovery programs access to the file Android system full control, including deleting and overwriting files. Although, in fact, recovery programs only need access in read mode.

Even if you find an application that does not require root, the chances of recovery will be extremely small. Try installing KingoRoot apps (installing root in a few steps) and DiskDigger for Android, it should work.

After resetting the Prestigio NK3, the system writes that the sd card is not supported and offers to format it. The reset was carried out with the card removed. There is a lot of necessary data, tell me if there is a solution?

Answer. Most likely, hard reset in no way affected the safety of data on the memory card. If you removed the memory card while other files were being written to it from the phone, the file table of the sd card could be damaged. You need to connect it to a computer or laptop through a card reader, check for reading errors using a standard Windows utility. If the bugs are fixed, the sd card should open on the phone. If not - Recuva program or DiskDigger with Dig Deep mode should find all files.

Wife made a hard reset on the phone Samsung Grand 2 Duo without making a backup copy. Photos and music are not so important, all phone contacts were lost and it was not possible to restore application data from Play market. In all applications, everything had to start over. Can you please tell me how to restore it?

Answer. The likelihood of recovering user data from applications depends on each application individually. So, if the user data was stored on the sd card, then you can recover the data. Otherwise, after a hard reset, you need to scan internal memory trying to find each separate file applications (the probability of doing this is quite small).

Phone contacts can be imported from a SIM card - of course, if you take care of backup contacts in advance. Check if contacts have been synced with your account Google entry and assigned to it by the Contacts service.

On the Internet, you can often find messages from owners of android devices that tell how users unsuccessfully played with gadget settings and what came of it all. In most of these 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 won't turn on

If, after resetting the settings, the android does not turn on, you should not immediately run to the service, as in some cases, the problem can be solved on its own. There are quite a few reasons why, in view of which, it is necessary to check everything possible 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 unfortunate feature full discharge they do not respond to charging for some time, which is why you need to wait at least half an hour.

If you were reset through the familiar 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 dial a special reset code on the device, entering which will lead to the 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. Fulfill this operation should be carried out independently only in those cases when the user is firmly confident in his skills and abilities to carry it out. Otherwise, it is better to let specialists take a look at the gadget so that they can quickly fix existing problems.

During flashing it is extremely important:

• Provide access to the gadget to charge in order to exclude the possibility of an emergency shutdown or disconnection during the firmware process;
• Monitor the stability of the connection between the computer and the android smartphone or tablet;
• Use the recommendations of the manufacturer of the device 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 in vain and you will have to start the procedure from the very beginning.

4 years ago

Hi all. Today I would like to analyze all the most common reasons why an Android smartphone may not turn on. I will not touch on those situations when you need to disassemble the phone and interfere with the electronic stuffing, 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 manage on your own and save some money (home accounting programs for Android will also help you save, 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.

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 a dead battery. And I perfectly understand when they tell me that they charged the smartphone all day, but it still does not turn on. Some devices have one unpleasant feature - if the battery is very much discharged, it will not charge, even if you support 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. After that, 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 connected to the outlet at this time.

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

Important. Do not reverse polarity.

Method number 2

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

Method number 3

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

Unfortunately, this technique does not work for many modern phones with non-removable battery. In this case, to reboot, you need to find the reset button and press it, for example, with a paper clip. It can be anywhere, but is usually located near the SIM card slot or on the back of a smartphone or tablet. Near the reset button, sometimes there is an inscription reset or off. 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 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 software of the smartphone. Then a hard reset will help us, or, in translation, hard reset. It is done differently for each device model. In order 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 a separate section on the blog 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 does happen smartphone does not turn on due to the fact that the contacts under the battery do not reach. To fix this, you need to use tweezers or a small screwdriver to bend the contacts to improve the connection to the battery. The main thing here is without fanaticism, otherwise you will only make it 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 a service center can help you.

Sincerely, Ivan Derbenev.
