Many users mobile devices  often face a specific problem - they don’t know how to unlock their Android. Often the reason for blocking is the forgetfulness of the user himself. Caring for the security of personal data, the owner sets a password to enter his device or graphic keywho subsequently cannot remember.

The easiest and most effective way to find out how to unlock the tablet is to contact the service center, where they will help you unlock the tablet or phone for a certain amount. But if you don’t want to spend the money, and the time it takes to remove the lock is enough, then these instructions are for you. Consider a few simple but at the same time effective wayshow to restore access to the device.

How to unlock your device on Android OS

At the beginning of all actions, you need to figure out which device you need to unlock. If this is a phone, then you can try the following.

We make a call to a locked phone, accept a call on it without resetting, minimize the call window and turn off the graphic lock in the settings. If you are going to unlock the tablet or the method indicated does not help, follow the tips below.

Method 1: Unlock via Google Account

In order to unlock this method, the device must be connected to the Internet. If so, then do the following procedure. We enter the wrong key several times in a row. Typically, devices give 5 attempts to enter the key correctly, after which the attempts are blocked for 30 seconds, and the message “You may have forgotten the graphic password” appears on the display. Click on it, a window appears prompting you to enter the login and password of your Google account. In this window, enter only the username (up to the "@" symbol) and password, click "Login". After that, you will be prompted to create a new lock password. Create a new one or click “Cancel”.

  In this method, it is important to remember the following. Creating a Google account after locking the device is useless. The account must be registered and synchronized in the device before the problem.

Also accounting google record can help unlock Android as follows, however, this method is not effective for all devices. From a third-party device (computer, smartphone, etc.) you should log in to your account, select the “Security” tab and go to the “Two-step authentication” section. The account is tied to your Android device - well, if not - try to bind to the phone number. In the "Two-step authentication" section, select "Application passwords" - "Manage application passwords", where you need to enter the account password again. In the appeared field “Step 1 of 2” create new password  applications, enter the name of the application (any), click "Create Password". This creates an application password, which at the same time is the password for the device.

We enter on your device your username from your Google account and the password just created and, as in the previous method. We create a new graphic key or cancel it.

Method 2: USB debugging using ADB Run

This method involves debugging the Android system through a console application for android computer  Debug Bridge (ADB), as well as its simplified user-friendly version of ADB Run. If USB debugging has been enabled on your device, resetting the unlock through the program will help you. To debug this method, we sequentially do the following.

The above method is universal and allows you to both unlock the tablet and manage android system  through ADB. After completing this manual, the unit will be removed.

If this does not happen, you need to try to repeat all the steps or unlock manually, through the command line of the computer. To do this, connect the device to the computer via USB, run the command line on the computer, in which we write the following commands, pressing Enter after each:

rm /data/system/gesture.key (this command will remove the pattern key)

rm /data/system/password.key (remove the password).

We disconnect from the computer, enter an arbitrary key, enter the device.

Method 3: unlock Android OS without debugging via USB and without ADB, Recovery mode

The following tips on unlocking your tablet or phone include booting the device in Recovery mode. Each device has its own way to turn on this mode, which can be found in the user manual or found on the Internet. But there is a boot method in Recovery that suits most Android devices. We carry out the following:

1. Turn off the device.
2. At the same time, hold down the “Volume +”, “Turn on” and “Home” keys (if there is such a key).
3. Hold the power button until the device responds (the backlight turns on, the image appears), the volume button - until the menu appears. You have entered Recovery mode.

  In order to unlock a device whose debugging via USB is disabled, and to understand the intricacies of the ADB program is scary or simply no desire, you need to download the file manager installer to the computer with access to system files  AROMA Filemanager. Copy the zip file to the SD card, insert the card into Android, load the device in Recovery mode, select the installation from the SD card and click ZIP AROMA Filemanager. After the system boots up, using this file manager you can manage it in Recovery mode, namely copy, cut, delete files, create new folders, etc.

So, unlock Android. In AROMA Filemanager, enable "Mount partitions at boot", exit the program, then run it again. The device sections will now be visible. Go to / data / system / and delete the gesture.key, locksettings.db, locksettings.db-wal, locksettings.db-shm files. When the files are deleted, we reboot the device in normal mode. Block removed!

As a rule, in the modern world, tablets have the ability to set both a standard password code and its graphic counterpart as information protection. The pattern key is one way to lock the device on operating system  Android. This type of password is liked by most tablet users. However, all the differences, pros and cons of these types of passwords can be completely unimportant if you forget this combination. It turns out that before you is a locked screen with nine dots or a password string that prevents you from using the tablet if you do not unlock it. A legitimate question arises: "How to unlock a password on a tablet?"

The first way. Google account

We'll start with the fact that there are several different ways to unlock and remove forgotten key from the tablet. The very first and, as usual, the most useless is to try to remember which symbols, numbers or letters you set as your key. It is useless for one simple reason: if you forget, then you don’t remember, most likely. In addition, by and large, it’s practically impossible to remember him, since he is very rarely associated with any of your associations. How to unlock the Android tablet, if you can’t remember the password? To prevent this from happening, use significant dates, last names or first names of close people or phone numbers as a symbolic password. With a graphic key, everything is much more complicated - you drew something and immediately forgot what it was. In general, it is better to record all passwords. More reliable.

Second way

How to unlock the tablet differently? Indeed, there is another way that will help to unlock a graphic or symbolic password that you forgot. The number of attempts to remember the key is limited and ranges from 5 to 10 entries (the number depends on the OS of the device). What happens when input attempts end? It's okay, your device will just ask you to log in to your Google account. You just need to enter your account  - and your tablet will be unlocked. If you are actively using this by email  or at least “tied her to his mobile phone”, Then there will be no problems with code recovery (the password from the system will be sent as an SMS message). Thus, your password on the tablet will be canceled, i.e. reset.

However, there are times when you learn about the existence of this type of mail only when this situation occurs. For such a force majeure, a ready-made mail address was invented, but they did not provide such an important thing as specifying a username and password at least in the instructions. All this is fraught with the fact that you have to use other methods. There are several other options they are divided into 2 types: with loss of information and without loss. You must clearly decide for yourself whether the files, games, documents, programs stored on the tablet are important to you, or whether all this can be easily restored, or backups. Consider them carefully.

If the information is not so important

Since unlocking the tablet most in a simple way? It will be much easier if the information you have saved on some other device, and its loss will not upset you. And most importantly, this method will not do any harm to the "machine". You simply transfer all user (personalized by you) settings to the factory settings (i.e. those that were before the tablet was purchased). This procedure is called hardreset. To use this method, it is enough to simultaneously press a special key combination. They are different for each device - it is better to look in the instructions that came with your tablet computer. The general action may be as follows: hold down the volume up / down keys and the on / back button, or the so-called "house".

If information is crucial and losing it will be a disaster

This method may not be safe for your device. This type of password reset will invalidate your tablet. Why? Because it will be necessary to install “left” on your device software  (It’s also called custom, that is, it doesn’t belong to this device or the manufacturer’s company), and you don’t always know what is being done and how. Unlocking the tablet will help the firmware. You can reflash your tablet both at home, so to speak, on your own, and by contacting a specialist. If you perform this operation incorrectly, then you risk staying with a completely inactive tablet.

But what about the guarantee?

For example, you are interested in the question of how to unlock. He has not yet expired the warranty period. Unfortunately, it is possible that resetting the password is not part of the terms of the guarantee agreement. In this case, the owner, who is the buyer of the tablet computer, is guilty of such a “malfunction” of the device, and the service center will be happy to offer you paid key unlocking services. However, do not despair, because there are official programs (utilities) that will help you without compromising the warranty. Information will be lost, but when using such software your device is less prone to "death". You can learn more about how to do this work yourself on the official website of the manufacturer.

How to unlock Explay tablet?

In solving this issue, tips on how to unlock the tablet described above will help. It will also show in more detail the reset procedure. First you need to go into Recovery mode. To do this, turn off the tablet and hold down the "back" key, press the power key, as you usually do. Release the back key. If you did everything correctly, a broken robot will appear on the screen. After that, you need to click the "Home" button and select "Reset to factory settings" in the list.

These tips should help you unlock your tablet. And most importantly - write down your passwords, then you will never have such a problem.

Hello everyone, today we will touch upon a rather useful and interesting topic that may possibly help someone, as it helped me. The other day, a friend brought a tablet and told me to make it. The problem was interesting in her - her daughter put a graphic key on the tablet. If anyone doesn’t know what I’m explaining: a graphic key is something like a password only without letters or numbers, you simply set the direction of the lines with your movements and thereby you can set the key. In order to unlock such a key, you need to draw in the same order and direction the lines that you set at the very beginning. Below is a photo of the key.

Graphic key

So there was a graphic key and my daughter entered this key incorrectly three times - the tablet was blocked and in order to unlock it, it was necessary to log in to the google account. Everything looks pretty simple and there seems to be no problem, well, logged in and that's it. But with us another case, it was impossible to log in, since wifi was turned off, the tablet does not support SIM cards (respectively, 3G), and in general it will not be possible to log in.

After reading on the Internet how and that I realized that there are a lot of ways to remove this key, there are very profitable ways that will not even affect the information stored on it. You can roll back by yusb if this feature is enabled on the tablet. If the tablet responds to a connection to the computer, then you can use the command line and one program, just remove this key, but in our case it did not work. If a person forgot his graphic key and the system we have is Android, and we just had an android, then in many tablets or phones there is a special combination of buttons when clamped, which, when the device is turned on, a panel will appear where we can reset all the settings and that's it device data to the beginning and we will have it as if from a box completely new. This method is called hard reset. In many devices, this must be done like this: turn off our device, hold down the volume button - or + and the power button. And then we should see something like a panel like in the photo, where we can choose to reset the settings and data of the device, reboot the device, etc.

Hard reset panel

But remember that all your information will be deleted after “hard reset”. In our case, this panel was for some reason not built-in and, delving into the Internet, I stumbled upon a video as a man makes a hard reset, on this particular tablet model. The point was that he downloaded this “hard reset” panel from the official website and downloaded it to a memory card (microsd). When he inserted a memory card and turned on the tablet, the panel appeared above the description and he reset all the settings. Also note that in order to choose something from the menu items, you need to poke the volume buttons, since the sensor will not work.

After that, I took out a memory card, downloaded the archive with the panel, unpacked it onto a memory card, inserted it into the tablet and turned it on. After that, a panel appeared in which I selected the item "clear user data (or wipe data / factory reset can also be written)" and, to confirm the selection, click on the on / off button. The tablet model was Asus MeMo Pad ME172V. Below is a link to the panel for hard reset and video how to do it all.

Judging by the statistics, many have problems unlocking the tablet. Unfortunately, even if the device is under warranty, it will not be unlocked for free. You have to pay some money, but then you will not need to make any efforts. Do not want to spend money on payment in the SC? It doesn’t matter, read on. In this article, I will touch upon restoring access to the device in case you forgot your password or graphic key to enter.

What to do to unlock the tablet on Android OS

1) If you had internet enabled

If your unlock is impossible, you can try the following: when you enter the key incorrectly many times in a row (usually after the fifth time within 30 seconds), carefully monitor the screen - a window pops up where you will be asked to restore access, and enter your login and password from mailbox  Google (gmail). In some cases, the offer to restore access will be located at the bottom of the key input field, as in Nexus 7.

Try entering your username (without @ gmail.com) and your account password. If you forgot your password or login, then you can try to recover them using Google tools here. If not, move on. This is the easiest way, but it does not work for everyone.

2) If you have software from the manufacturer

Another option is to unlock the tablet using proprietary software. Like Kies from Samsung or HiSuite from Huawei. It happens that people forget (or don’t know, in the case of buying used devices) even the Google mail box to which they are attached google account  Play This software can help.

3) If USB debugging was enabled in the settings

A very rare method of resetting the unlock via the ADB RUN program, it can help you only if your tablet has USB debugging enabled in the settings. With a locked tablet, you naturally cannot enable debugging. Nevertheless, if you can’t, try it, suddenly this option was turned on, but you didn’t know.

1. Download the ADB driver for your Android tablet. Use the Google search, enter the query “Adb driver for Nexus 7” without quotes. Instead of Nexus 7, enter the name and model of your device.
  3. Install the ADB driver on a computer with Windows 7 or 8. A detailed process for installing drivers on a PC is described.
  4. Download and install the ADB RUN program on your computer
  5. Run the program, you will see a simple main menu.

6. Connect your Android device to the computer using a USB cable
7. Press the “1” button on the keyboard, and confirm your choice with the Enter key. Thus, you activate the “Device attached?” Function, which will check whether your tablet is connected to the computer.

If the program reports that the tablet is not connected, it means that the ADB drivers are either not installed, or the wrong driver is installed. Reread items 2 and 3, and download the appropriate driver, and then install it correctly. Happened? Go ahead. If it did not work out, there is no point in continuing.

8. See the line “Unlock Gesture Key”, and the number next to it? This is the point we need. Press the number "6" on the computer keyboard, confirm your choice with the Enter key.

  9. Next, a window opens in which two automatic methods are offered. If you press “1”, the gesture.key file responsible for storing the graphic key is deleted. After that, you just have to reboot the device, and enter absolutely any graphic key. The second method will simply zero out the system.db file, and you can use your device as before.

That's all, if everything was done right, congratulations. If this doesn’t work, try again by carefully reading each item before, or try to do the same, only in command line. To do this, follow the next path on the computer with the tablet connected: START button in Windows -\u003e Run ... -\u003e type “cmd” without quotes -\u003e enter the following commands, after each line press Enter on the keyboard:
  cd /
  cd adb / progbin
  adb shell
  rm /data/system/gesture.key

3) If there is recovery menu

If there are no more options, but you have one, do it. Look on the Internet or instructions on how to do it for your tablet model. Keep in mind that all your data stored in internal memory  devices to be deleted. The memory card will not be affected.

Dima gave excellent advice in the comments, and Alexander made a useful clarification:

1. turn off the tablet
2. press simultaneously the keys increase volume"+ Key" house"(If any) + power key
3. hold the power button until the vibration response and then release the power button
4. at the same time we still hold the volume button until the menu appears
5. then volume buttons " more less"(+/-) select" wipe data / factory reset»And click on it with the power button
6. if another list appears with one item yes  and the rest no  - choose volume yes  and press the power button
7. wait until the reset occurs, and then press the first line from the top (" reboot system now") - the tablet will reboot
8. that's all, such a reset should solve the problem

ATTENTION, if the method above did not help you, press the " decrease volume"And power key  in the second paragraph.

If on your tablet there are no volume buttons, and you need to do a reset, then you already need to read the instructions. Everyone does it differently. But in Explay Informer 701, hard cutting is done like this:

1. press and hold the back button
  2. Press, but do not hold, the power button 1 time
  3. release "back"
  4. Android itself appears, press the "home" button
  5. a menu has appeared, select a reset in it

Owners of Chinese tablets may come in handy advice from Natalia, which she gave in the comments:

1. Turn off the tablet

2. Press the volume button + and simultaneously the power button briefly for 4 seconds, then release the power button and alternately press the volume button then + then -, then + then - and so on several times, not quickly alternately

3. Then again hold the power button and the volume + button together and then the recovery menu should pop up.

I didn’t immediately succeed, I tried different options, I pressed in a different order with different speed, in general, on a happy occasion, I found by typing the sequence of pressing these buttons, at first the android with a red belly popped up at me, which means that the unlock option does not work and you need to try another option. So, after the desired recovery menu pops up, we look for “wipe data / factory reset”, we move with the volume button and we make a choice with the power button. Then a column appears where a lot of No No No No click yes delete all user data then another column pops up, there we look for “reboot system now” click and everything is ready.

4) If there is no more hope

Well, what can I tell you. The surest way to solve the problem with the graphic key is this.

In case of complete despair, I recommend that you simply take the tablet to a service or repair. Yes, you will pay some amount, but believe me, sometimes it’s better to just pay than to suffer from a problem, spending a lot of time and nerves on it, and still not solve it. Besides, if it’s not your fault but your friend’s fault, why not take this amount from him? It seems logical to me. So you can “get enough” by taking a little more than the unlocking cost from experts, as moral compensation. But your business, of course.

If the user has forgotten the pin code or password, then he will have to make a little more effort to unlock the tablet than if it were a graphic code. You can bypass the lock of the latter by having access to the Web and remembering your credentials on Google. The password or code, if the owner of the device has forgotten them, can usually be restored only after a hard reboot or as a result of using special utilities.

Third-party unlock tools

One of the programs that allows you to unlock the android is Screen Lock Bypass Pro. She is paid. Nevertheless, this is a reliable and inexpensive way to unlock the device by storing all the data on it if you forget the pin code.

In addition, to work with the utility, two conditions must be met - access to the Network and an account on Google+. If they are respected, then you need to do the following:

Unfortunately, the utility may not be suitable for your device and your version of Android, since not all devices work with Screen Lock Bypass Pro. The method described above to unlock the tablet without losing personal files is not the only one. If you have forgotten the password for the device, you can use the ADB method.

Use ADB to unlock

In order to be able to unlock your device in this way, the possibility of USB debugging must be enabled on the Android tablet in advance. Therefore, if you set a pin code for login, you must immediately make this mode active:

1. Go to the "Settings" section of your device.
2. In different devices, the USB debugging item can be in the “For Developers”, “Development”, “Developer Settings”, etc. directories. Go to a similar section of your device.
3. Next to the USB debugging item, check the box.

If the above steps were performed before the user forgot the password or code, then to remove the lock, you can use the features free program  Adb. To unlock the device, you need a computer:

After the manipulations, you can set a new password. If the described methods did not help reset the password that the user forgot, then you will have to use the procedure provided by the developers Hard reset  with the loss of all personal data.

Password reset for older versions of Android

If the user has forgotten the password on the kind of Android tablet, which in addition has the ability to install a SIM card, as well as an application for making and receiving calls, then you can try a very simple way to unlock it:

1. Install any valid SIM card on the tablet;
2. Make a call to your device, accept a call from it, and phone application  then collapse with the Home button;
3. While the call is being made, the user has unlimited access to the device, which makes it possible to unlock and set a new key.

Most modern devices with latest versions  Android has not had this security hole for quite some time. Therefore, it will be possible to do this in the case when the user has forgotten the pin code of a really new Android device.

How to prepare in advance for a possible hard reset

Even a hard reboot will not lead to the loss of important personal data if you previously knew how to make Android backups and saved them. They are placed in cloud storage  and almost do not take up space there. To have archival copies installed applicationssettings wireless networks, accounts, etc., do the following:

Performing a backup allows you to relatively smoothly unlock your Android tablet using Hard Reset when the owner has forgotten his password or PIN.

Hard Reset Sequence

Before performing a hard reset, remove the SIM and SD cards just in case. Although they are not affected by this procedure, it is better not to risk it.. In most cases, the sequence of actions for performing hard  Reset on any tablet is similar, only a few may differ for different device models:

On some devices, access to the Recovery menu may vary. Sometimes, in order to be able to unlock an android device, you need to hold three buttons at once - Power, Volume Down and Home. In some cases, instead of the Volume Down button, you have to press Volume UP or press on the middle of the volume rocker.
