The graphic key is a very reliable data protection on tablet computer, but sometimes the owner of the gadget becomes its hostage. For example, if he forgets his key. It is also not uncommon for a device to fall into the hands of a child who, by random actions, creates graphic password, saves and, of course, does not remember it. And it becomes impossible to log in.
To everyone's joy, this situation is not fatal. In most cases, the tablet can be unlocked by resetting graphic key. It happens that you have to sacrifice the information stored in the device's memory, but more often you can get by with "less bloodshed". Let's look at six ways to unlock an Android tablet if you can't remember your pattern password.
Via SMS
This option is one of the quick and simple, but it will only help those who foresaw the situation with an accidental blocking of the gadget and installed the SMS Bypass application on it in advance, and also received superuser (root) rights. Naturally, the device must be equipped with a SIM card reader.
So, how to unlock an Android tablet using SMS Bypass if you forgot your pattern?
- Install the app from Google Play. It's not free, but it only costs $1.99. To install, you need access to the global network and a Google account.
- Give the application full access to the device.
- Set to SMS Bypass secret code to reset the graphic key (its default value is 1234). To prevent outsiders from doing this, it is advisable to come up with a more complicated code.
- When blocked, send an SMS from another phone to the SIM card number of your tablet with the text “secret_code reset”. For example, "1234 reset". The graphic key will be reset.
Through a phone call
Note! This option has one serious limitation - it only works on Android version 2.2 or lower. And such gadgets are quite rare today.
How to unlock the tablet with a call if you forgot the pattern?
- Make a call to the locked device from another phone.
- After receiving a call to Android 2.2 it becomes possible to enter the application “Settings” -> “Protection” -> “Lock screen” and change the pattern.
Another option is to call from the locked tablet itself. After dialing the number and pressing the call button, the desktop opens literally for a moment. If at this time you have time to click on the application icon (any), you will be able to enter the “Settings” and reset the key.
With a Google account
After five unsuccessful login attempts, the “Forgot pattern?” button will appear on the tablet screen.
Click on it, sign in to your Google account and go through the process of restoring access.
If your device does not have Internet access, you can use one of the methods to get it:
- Press the button Emergency call”, dial the number *#*#7378423#*#* , on the menu “ Service tests” select “WLAN” and connect to wireless network WiFi.
- Install a SIM card in the tablet with a sufficient amount of money in the account and an activated option to connect to the Internet.
- Connect to tablet via USB-LAN adapter network cable provider.
Through the recovery menu
recovery mode
recovery is special treatment recovery, from which the system settings are reset to the state as after purchase, flashing the device, obtaining superuser rights, restoring data from a backup, etc.
Note! To get into it, you need to turn off the tablet and when you turn it on again, press together with the Power button the volume rocker to increase or decrease the volume (each manufacturer has its own combination of buttons).
You can also do this using the ADB Run program, which is installed on a Windows or Linux computer. To enter the Recovery menu, the tablet must be connected via a USB cable to the PC, having previously enabled USB debugging in the “Settings” -> “Developer Options” menu.
After that, run ADB Run, select “Reboot” from the menu and then “Reboot Recovery”.
Recovery mode is available on the vast majority of gadgets running Android, but not all. If yours does not have it, install it separately - with it you will have one more way to unlock the tablet if you forgot both the pattern and your Google account. You can use adb run to install fastboot mode or the Odin flash utility (for Samsung gadgets).
Unlock
To unlock the device, you need to delete the file /data/system/gesture.key. But there is no Recovery menu file manager. For it to appear there, you need to install it in advance. For example, great suitable program Aroma File Manager, which directly from Recovery opens access to system files.
If USB debugging is enabled on the tablet, you can also use ADB Run to remove gesture.key by selecting the menu item Manual and running the command adb shell rm /data/system/gesture.key.
Another way to remove this file is to install special update, which only works if there is a Recovery partition. This update resets the graphic key.
Through data reset
Resetting data is one of the last resorts when no other methods have helped. It is not recommended to start with it for the reason that after that you will lose your saved SMS, phone book, installed apps and some other data not stored in the Google account. Pictures and melodies will remain in place.
To reset the data, you will also need to enter the Recovery menu and select the option wipe data|factory reset. Let's figure out how this is done on devices of some brands.
Samsung
- On tablets: turn off the device and press the volume up rocker and the Power button before turning it on.
- On newer smartphones: Turn off the device and press the Power, Home and Volume Up buttons before turning it back on.
- On older smartphones: Turn off the device and press the Power and Home buttons before turning it on again.
HTC
- When turning on, press and hold the Power buttons and the volume down rocker.
- The wipe data|factory reset option on some HTS models is called clear storage.
Huawei
- Turn off the device, pull out battery(if it is removable) and insert immediately.
- When turned on, press and hold Power and volume up rocker.
On some models Huawei smartphones recent years release data reset is performed by unlocking the bootloader using the HiSuite and ADB Run utilities. The smartphone will then be clean, as after purchase.
Prestigio
How to unlock a Prestigio tablet and smartphone if you forgot your pattern?
- Turn off the device. When turning on, press and hold the Power, Home (if any) and volume up rocker buttons.
- After executing the instruction wipe data|factory reset in the Recovery menu, select delete all user data and next - reboot system now.
flashing method
Flashing the device is the most complex and risky method. It remains to be resorted to if you have forgotten the pattern, you do not have the Internet and you do not know how to unlock the tablet in other ways. It is assumed that you know how to flash Android devices and a suitable firmware with all necessary tools you already have.
official source original firmware is the website of your device manufacturer. All other sources can exacerbate the problem by turning the gadget into a “brick”.
The following software is used to flash certain models of mobile Android devices:
- For Samsung, it's the Odin utility we've already mentioned.
- For LG - KDZ Updater.
- For Sony - Flsahtool.
- For devices different brands- FastBoot from the Android SDK.
- For devices on chips MediaTek(which is mainly used on Chinese gadgets) - SP Flash Tool.
To install firmware universal instruction no - you must first find it on the website of the developer of the flash driver utility and study it in detail. If everything goes without incident, you will get a pristine tablet with a brand new Android OS. There will be no trace of the graphic key on it.
Judging by the statistics, many people have problems unlocking their tablet. Unfortunately, even if the device is under warranty, it will not be unlocked for free. You will have to pay some money, but you will not need to make any effort. Do not want to spend money on payment in the SC? No problem, read on. In this article, I will touch on restoring access to the device in case you forgot your password or login pattern.
What to do to unlock the tablet on Android OS
1) If your internet was on
If you can’t unlock it, 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 will pop up asking you 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 entry field, like the Nexus 7.
Try entering your username (without @gmail.com) and account password. If you forgot your password or login, then you can try to recover them using Google here. If it doesn't work, we move on. This is the easiest way, but does not work for everyone.
2) If you have software from the manufacturer
Another option is to unlock the tablet using proprietary programs. Like Kies from Samsung or HiSuite from Huawei. It happens that people forget (or do not know, in the case of buying second-hand devices) even the Google mailbox to which Google account play. This software can help.
3) If USB debugging was enabled in the settings
A very rare unlock reset method through the ADB RUN program, it can only help you if your tablet has USB debugging enabled in the settings. When the tablet is locked, you naturally cannot enable debugging. Still, if you can’t, try it, suddenly this option was enabled, but you didn’t know.
1. Download ADB drivers for your Android tablet. Take advantage 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. The 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 your computer with a USB cable
7. Press the "1" button on the keyboard, and confirm your choice with the Enter key. This will enable the “Device attached?” function, which will check if your tablet is connected to the computer.
If the program reports that the tablet is not connected, it means that ADB drivers either not installed or the wrong driver is installed. Re-read paragraphs 2 and 3, and download the appropriate driver, and then install it correctly. Happened? Move on. If it doesn't work, there's 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.
3) If there is a Recovery menu
If there are no more options left, but you have one, do it. Look on the Internet or for instructions on how to make it for your tablet model. Please note that all your data stored in internal memory devices to be removed. The memory card will not be affected.
Dima gave excellent advice in the comments, and Alexander made a useful clarification:
- turn off the tablet
- press the keys at the same time turn up the volume» + key « house» (if any) + power key
- hold the power button until the vibration response and then release the power button
- at the same time, the volume button is still held down until the menu appears
- then use the volume buttons more less» (+/-) select « wipe data/factory reset and press the power button on it
- if another list with one item appears yes and others no- choose volume yes and press the power button
- wait until the reset occurs, and then press the first line from the top (“ reboot system now") - the tablet will reboot
- that's all, such a reset should solve the problem
ATTENTION, if the method above did not help you, press the keys " turn down the volume" and power key in the second paragraph.
If there are no volume buttons on your tablet, but you need to reset, then you already need to read the instructions. Everyone does it differently. But in Explay Informer 701, a hard reset 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 personally, press the "home" button
5. the menu has appeared, choose reset in it
Owners of Chinese tablets may need advice from Natalia, which she gave in the comments:
1. Turn off the tablet
2. Press the volume button + and at the same time the power button for a short time for 4 seconds, then release the power button and alternately press the volume button then + then -, then + then - and so several times, not quickly in turn
3. Then again hold the power button and the volume button + together and then the recovery menu should pop up.
It didn’t work out for me right away, I tried different options, I pressed in a different order with different speed, in general, by a lucky chance, I found by typing a variant of the sequence of pressing these buttons, at first an android with a red belly popped up, which means that the unlock option is not suitable and you need to try another option. So after it pops up desired menu recovery, look for “wipe data / factory reset” move with the volume button and make a choice with the power button. Then a column appears where there is a lot of No No No No, click yes delete all user data, then another column will pop up, look for “reboot system now” there, click and you're done.
4) If there is no more hope
Well, what can I tell you. The surest way to solve the problem with a graphic key is.
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 with a problem, spending a lot of time and nerves on it, and never solve it. In addition, if it is not you who is to blame for the problem, but your friend, why not take this amount from him? It seems logical to me. So you can “get rich” by taking a little more than the cost of unlocking from specialists, as a moral compensation. But it's up to you, of course.
Greetings!
In connection with the mass distribution of gadgets and devices that operate under the operating Android systems, the question of their protection and getting rid of malicious software.
Malicious software is divided into categories, each of which has its own properties and characteristics. In this article, we will analyze the most common categories of malware for the Android operating system and consider the most effective methods to combat this evil.

The most popular type of malware is trojan. His destructive activity is to collect and send to criminals confidential information, starting from personal correspondence in messengers and ending with data bank card when making a payment.

2)
After the scan is complete, delete all found suspicious files.
As a rule, voiced actions are enough to clean android system from trojans.
Ad virus removal
Applications that add ads are also quite common. Unlike Trojans, their malicious action is to add ads to the system interface and browser. As a result, the responsiveness of the interface slows down and the traffic consumption increases!
The most common way this type of malware enters the system is through the installation of pseudo-free games.
Most effective way can be called the installation of the AdAvay application, which will block access to addresses from which advertising content is downloaded.
However, this method is associated with some difficulties, namely the need to obtain root access on the device being installed (the application does not work without it) and installation of the application from the site, for which in the device settings you need to check the box unknown sources
, which is located in Settings -> Safety.
If these difficulties do not stop you, then as a result you will practically completely get rid of from annoying pop-up and flickering ads in apps as well as the browser.

1) Turn off the device and remove the SIM card.
2) Turn on the device and as quickly as possible (before the blocker banner appears) go to Settings -> For developers and check the box next to USB Debugging, and then select the suspicious app from the menu. And finally, check the box next to the item that has become active Wait for the debugger to connect.
If the menu Select application to debug you have a lot of applications displayed, and you find it difficult to identify a malicious one, then its name is very a high degree probabilities can be highlighted in Settings –> Safety –> Device administrators.
To increase its own privileges and make it harder to remove, the malware usually adds itself to this list.
The menu section may also be missing. For developers. To activate it, you need to go to the menu About Tablet PC and click on the item several times in a row Build number.
You may have to reboot the device several times in order to have time to do the necessary manipulations.
3) After the manipulations, the system interface will be unlocked and you only have to Settings –> Safety –> Device administrators uncheck the malicious application. This must be done in order to remove privileges that block the removal of a malicious application by regular system tools.
4) Remove the malicious application using regular means, to do this, follow the Settings -> Applications -> <имя приложения>
Summary
By following these instructions, you can quickly and effortlessly deal with the most diverse types of malware that are found on smartphones and tablets running on operating system Android.
And iOS often comes with viruses that behave in unpredictable ways. So, many users are faced with the fact that the message “Your phone has been blocked by the Ministry of Internal Affairs” appears on the screen - allegedly for viewing pornography and other unpleasant content. As a rule, along with this, access to any menus and applications of the system is lost, and the message itself indicates the need to pay a fine.
We will immediately clarify the situation - such information is invalid, because the Ministry of Internal Affairs does not deal with such blocking, does not accept fines by bank transfer, account replenishment and other types of operations.
Therefore, do not believe such a message - this is, in fact, a virus designed to extort funds from users. Note that unlocking the phone in this case is not too easy, but it is possible, and you can do it yourself.
Sometimes users may encounter the inscription: "Your phone has been blocked by the Ministry of Internal Affairs." This virus completely paralyzes the device
Let's find out if the Ministry of Internal Affairs of the Russian Federation is on the iPad or Android devices with a few simple steps.
Removing the virus "Your phone is blocked by the Ministry of Internal Affairs" on Android
In the event that a similar message appeared when entering the site, try pressing the “Back” key - if this helps, it means that you have encountered spam, and closing the site will easily save you the problem.
But if the text allegedly from the Ministry of Internal Affairs of Russia appeared after installing the program or visiting some site, and you cannot perform any operations, the keys do not respond to touch - this is really a virus.
You can remove it in several ways. For example, do the following:
- Go to your store through the Play Market on a computer or other gadget.
- Install any of the antiviruses, but when determining the download location, select the infected device.
- Reboot the tablet or smartphone with the malware, after which the antivirus will start working in the background - you will not see this because of the message, so just wait 10 minutes.
- So, if the antivirus finds malicious files and deletes them, the message will disappear automatically. Reboot the system after the specified time.
If that doesn't help, try this method:
- Translate the device - turn off the gadget, then hold down the power key and increase the volume for ten seconds.
- Select Safe Boot Mode.
- If the system reboots and you can perform actions, go to settings and uninstall the application that caused the blocking message.
- If the keys to delete or stop a malicious application are blocked, this means that it has received administrator rights. Then you have to reload safe mode, go to the Play Market, download the antivirus.
- Reboot your device and it will start checking. After it completes, reboot again.
What if these options don't work?
It happens that you can’t turn on the antivirus in any way, and even more so remove the program that caused the text about the virus from the Ministry of Internal Affairs of the Russian Federation to appear. In such a situation, it remains only to return to the factory settings using the following actions:
- Go to the recovery menu.
- When the window appears with available operations, use the volume keys to navigate to the line "Wipe data / factory reset" and select it.
- The tablet or phone will be reset to factory settings.
- Reboot the gadget again, after which it will be unlocked.
This method is offered last of all due to the fact that when you return to the factory settings, you lose your data in the system - applications, information from them, saved pages, and so on. On the memory card, all data must remain in place.
How to remove the message about blocking from the Ministry of Internal Affairs from the iOS device?
Note that such text appears as a pop-up window and does not block the use of the system. So you can remove it like this:
- Go to the "Settings" section.
- Select your browser menu.
- Click on the "Clear history and site data" line.
After these steps, the message will no longer bother you, but do not visit the site where you encountered such extortion again.
Now you know how to unlock your phone from the virus of the Ministry of Internal Affairs of Russia, you are familiar with the fact that such messages are false. Therefore, do not be afraid of them, but rather clean your device of viruses using the above methods and then carefully go to third-party sites, and download applications from reliable sources.
A tablet is a very convenient thing for a modern person. A lot of functions combined in one device pleases any tablet owner. However, sometimes unforeseen situations arise: you turn on the tablet, and it is blocked, and you do not know how to fix it.
This topic applies to most tablet models based on the Android system. What to do if the tablet is blocked? This article will talk about ways to restore access to the device.
Reasons why the tablet is blocked
The main reason for blocking the device is an authentication problem. In other words, if you forget your password or the so-called login pattern, you will not be able to use your tablet. A similar situation (when the tablet is blocked) can occur with models of any manufacturer: Samsung (Samsung), Acer, Lenovo, DNS and less common brands Texet, Explay, Prestigio, etc.
Another reason is also possible: the Android is infected with a virus. Malware penetrates the system and blocks the tablet, demanding to send SMS. In no case should you send an SMS message to the required number. We offer several proven ways to solve the problem of blocking the device. After trying each of them, you will most likely unlock the device and be able to use all its functions.
How to unlock the tablet. Recovery methods
1. First of all, you need to apply the simplest methods if the tablet is blocked. Enter random numbers, letters - the system, of course, will answer in the negative. After several unsuccessful attempts to log in to the system, Android will prompt you to enter your authentication data (login and password) from your Google account ( Account Google).
Perhaps this is the most elementary way to unlock your "pocket computer", however, in practice, this will not work on all tablet models. And still try to enter the login (your Email without the "dog" and gmail.com) and the password from google box. In case you do not remember this data, try to restore it through by going to the Google website.
2. Well, if you took care to make a backup in advance - backup firmware. In this case, if the tablet (Samsung, Acer, etc.) is blocked, but it is equipped with a data recovery mode (recovery), then you can simply roll back to the backup.
3. The next method is to restore access to the system using proprietary programs. As a rule, such programs are bundled with branded tablet models like Asus, Samsung (Kies program), Lenovo or Acer. What else applications are useful for is that they allow you to “remember” the name e-mail box on Google - the functions built into the program will display all the necessary data.
4. A rather tricky method, but not at all a fact that it will work on later models of tablets, and also not all tablets have the ability to insert a SIM card. The bottom line is that you need to call the SIM card number, and during the call go to the "Settings" menu and unlock. This method applicable rather for smartphones Samsung, HTC, etc.
5. If the above methods did not help unlock the tablet, and you do not know what to do already, do not despair. There is a way out and it's called hard reset (full reset). But be aware that all data stored in the tablet's memory will be permanently deleted. Only those files that are on the memory card will remain.
How to make a hard reset with an example samsung galaxy Note, if the tablet is locked: hold down the volume up, home (home) and tablet power buttons at the same time, then release the latter. A menu will appear where you need to select "Wipe data / factory reset", and then "Yes - delete all user data", confirming by pressing "Home".
