They say that a dull pencil is sharper than the sharpest memory, but alas: we never stop forgetting passwords, and with them the fact that it is better to entrust their storage to paper or a specialized program. In addition to the “forgetting to forget” properties of human memory, passwords are also lost for other reasons - due to children’s pranks with the phone or sabotage by someone close to them. Although... when the problem has already arisen, the reason fades into the background. And the first step is the desire to quickly figure out how to unlock the phone. Therefore, now we will study ways to remove the blocking.
Unlocking using branded services and applications
It’s better to remember that your smartphone will one day be permanently locked before it happens. And prepare workarounds in advance, since some mobile device manufacturers provide this opportunity. For example, Samsung has a Find my mobile service, which allows you to remove any password, PIN code and fingerprint of the owner without direct access to the device. The condition is that you have a Samsung account, link your phone to it and pre-set it up for remote control.
Manufacturers of Huawey gadgets also took care of users by creating a proprietary utility HiSuite, which allows you to recover a forgotten password via a computer.
For HTC brand gadgets, there is a proprietary Windows utility, HTC Sync Manager, which makes it possible to install applications on the phone via a PC, to which the first one is connected with a USB cable. With its help, you need to load the Screen Lock Bypass utility into your mobile device (supports versions from 1.5) and perform unlocking steps. However, to use this feature, USB debugging and Internet must be enabled on the locked gadget.
There are similar things for devices of other brands, so before moving on to hardcore methods, such as hard reset or flashing, try to look for information about proprietary secrets for unlocking your smartphone or tablet on the Internet. If such things exist, they will definitely be written about somewhere.
How to turn on the Internet on a locked gadget
The majority of methods for unlocking smartphones and tablets are effective under one condition - if the device is connected to the Internet. You can turn on the Internet without access to your desktop in different ways, but, unfortunately, they do not always work.
Here are some of these methods:
- Reboot your device. Your task is to catch the moment the notification panel appears at the top of the screen, behind which the curtain is hidden, and have time to pull it down before the lock screen opens. At the same time, you will have the opportunity to enable Wi-Fi or packet data transmission via 3G/4G. The method works on smartphones and tablets of different brands - Meizu, Xiaomi, Lenovo, Asus, etc., but not on all.
- On Sony Xperia smartphones, Internet access is enabled through the service menu, which is opened by calling the number *#*#7378423#*#*. You can dial the number using the emergency call keypad while on the lock screen. After opening the menu, go to the “Service Tests” -> “WLAN” section, where the option to activate Wi-Fi is available, and turn on the Internet. By the way, it is possible that the method will work on devices of other brands.
- On some smartphones, the 3G/4G packet data function is activated through the power button menu.
- Sometimes it helps to replace the SIM card with another one, the tariff plan of which includes an Internet connection service, and there are enough funds in the account.
- If none of the methods helped connect your mobile device to the Internet, the last thing left is to connect it directly to the LAN port of the router using a LAN-USB adapter and an OTG cable. A positive result is achieved in approximately half of the cases.
Unlocking with Google Account
Important! Before setting a password or pattern on your phone, you need to register a Google account on it, the details of which you remember well. Better yet, store it in a safe place. By doing this you will insure yourself against many serious problems in the future!
After entering the wrong pattern 5 times, the device will prompt you to try again in 30 seconds. Click OK. After half a minute, the message “Forgot your combination?” will appear on the lock screen. After clicking on it, the system will prompt you to enter the login and password of the Google account that is linked to the phone. Entering the correct data will unlock the screen, and then Android will prompt you to create a new pattern.
The method of removing the lock by entering a known login and password for the Google account linked to the device has helped many, but not everyone. It works more or less stably on smartphones and tablets running Android versions 2.2-5.0, less often on modern ones. However, there are devices that do not “follow” this technique at all, and to unlock them you have to look for other means.
Some users who have forgotten the password of their Google account recover it, or rather change it, by logging into the service via a computer. If you've changed your account password, you'll likely be able to unlock your phone for at least 72 hours.
Unlock by call
The method of unlocking by calling exploits a certain vulnerability in the firmware, so on modern devices it works extremely rarely, almost never. But the majority of devices running Android 2.1 and older are unlocked quite often with its help.
The method is to call a blocked phone. After accepting the call, press the Home button to go to the desktop. Without interrupting the call, open the Settings app and turn off the key prompt.
Another option for this method is to make an outgoing call from a locked phone (if the function is supported). After dialing the number of a non-existent subscriber, the desktop opens for a short time and it becomes possible to pull out the curtain, from which you can go to settings and disable protection. For the operation to be successful, you will most likely have to make several attempts.
Unlocking rooted devices
Devices whose owners have managed to obtain root rights are somewhat easier to unlock, since there are slightly more options for this. One of them is the SMS Bypass mobile application. It is paid, it costs about $2, but in a blocking situation it can provide you with invaluable help.
Attention! If your device is not yet locked, be sure to install the application before the opportunity to use it comes! Do it now!
SMS Bypass works very simply. As long as the smartphone is not locked, the application does not bother the owner in any way. But in case of problems, you just need to send an SMS message with the text “1234 reset” to your number so that the blocking is reset. After receiving the SMS, the problematic smartphone will reboot. After turning it on again, you should enter any pattern or password on the lock screen, and access will be granted.
By the way, some devices with root rights support installing applications even in a locked state. Naturally, not directly, but through a computer. To do this, you will need a phone and PC synchronization program, Internet access and a password for your Google account.
If there are 2 Google accounts on the device, both are rooted, and login is blocked for only one
Log in as the second user. Using the file manager Root Explorer, Root Browser or their equivalents, open the /data/system directory and delete the following files:
- gesture.key;
- locksettings.db-wal;
- locksettings.db;
- locksettings.db-shm.
After this, the first user will also be free to log in.
Unlocking devices with custom Recovery menu
Users install the custom recovery menu - Clockwordmod (CWM) or TWRP, which is called by pressing certain keys before loading the operating system on Android gadgets. If you have equipped your device with a similar tool, then you have several more ways to unlock it.
In addition to the menu, you will need the file manager AROMA Filemanager, which works in the recovery environment. This application can be installed even on a locked phone by placing the installation file on a memory card and booting into Recovery. With it, you will get full access to Android OS directories without loading the system.
Owners of smartphones with the CWM menu installed can use another application - Screen Lock Cracker. Its only function is to reset passwords and graphic keys that protect the system login. You just need to place the application on an SD card, insert it into the gadget, enter the recovery menu and launch it. After it works, the entrance will be unlocked.
Unfortunately, the developers of Screen Lock Cracker do not guarantee its correct execution on all devices, but you don’t have to worry about the data in the device’s memory. Even if the password is not reset, user files will not be affected.
Unlocking using ADB
ADB (Android OS Debugging Bridge) is a console application that is installed on a computer as part of the Android SDK and is used to control connected Android devices. ADB is intended for debugging the system, devices and application development, but it can also serve our purposes. If such a package + ADB Android Drivers is installed on your PC, and USB debugging is enabled on your smartphone or tablet (or the CWM recovery menu is installed), then you have several more ways to remove the lock.
To use the methods listed below, you additionally need root rights (since you use ADB, you most likely already have them). If they are not there, the instructions may not work.
Method 1
- Connect your locked phone to your PC using a USB cable.
- Launch a command prompt with administrator rights (if you are running Windows) and run the following commands one by one:
cd [adb directory]
adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name="lock_pattern_autolock";
update system set value=0 where name="lockscreen.lockedoutpermanently";
.quit
Once completed, restart your phone and enter any password or key on the lock screen. If he won't let you into the system again, try the second method.
Method 2
- Run Command Prompt as Administrator.
- Follow the instructions below:
cd [adb directory]
adb shell
su [if you don't have root rights, skip]
rm /data/system/gesture.key
rm /data/system/locksettings.db
rm /data/system/locksettings.db-wal
rm /data/system/locksettings.db-shm
reboot
The phone will restart.
If your device does not have USB debugging enabled, run the above commands in the CWM environment.
The original description of these unlocking methods in English is given.
Hard Reset and flashing
The two remaining options for restoring access to a locked phone or tablet can be called methods of desperation. They are resorted to when absolutely everything that can be applied to the device has been tried, but “things are still there.” Unfortunately, both methods do not provide for saving user data, which means all photos, videos and other files that you stored only on your mobile device will be lost.
When performing a Hard Reset, the phone or tablet will return to the state it was after purchase. And flashing is equivalent to a complete reinstallation of the operating system.
A hard reset is quick and easy. Using the instructions for your gadget model, enter the Recovery menu (the screenshot shows the standard recovery menu that is installed on most devices) and select the Wipe data/Factory reset option. The device will reboot and in a few minutes will become pristine.
Reflashing is also not particularly difficult. The most time-consuming thing about it is to find a distribution kit suitable for your model. Then simply follow the installation instructions that usually accompany it.
If you have forgotten your set password or pattern on Android, there is no reason to panic. Access to your smartphone can be restored, and there are several ways to remove the lock. The updated instructions describe each of them in detail.
How to reset a password or lock on Android

13. How to remove the unlock key on Huawei and Honor: backup PIN code
On Huawei and Honor, in addition to the pattern key, a backup PIN code is used. Therefore, to unlock the device, you need to draw the pattern incorrectly 5 times, and the display will display the message: “Try again in 1 minute.” Wait 60 seconds for the “Backup PIN” button in the lower right corner to become active. Click on it, enter your PIN and the unlock key will be instantly reset.
14. Backup PIN on LG
When setting a screen lock on LG, you need to set a backup PIN code, which you can enter instead of a pattern or password, and unlock the phone.
To do this, draw an irregular graphic pattern until a message appears indicating that input is blocked for 30 seconds. Click “OK”, select “Forgot your pattern?” at the bottom, enter your PIN code and click “OK”.
15. Smart Lock function
Starting with Android 5.0, the system has a Smart Lock feature that allows you to disable the screen lock in certain situations. For example, when the device is at home or connected to a trusted device via Bluetooth. Depending on the device manufacturer, as well as the version of Android, there are different unlocking options using Smart Lock, such as voice detection, face recognition and others.
Of course, Smart Lock is a convenient feature that simplifies the use of a mobile device. But thanks to it, attackers can gain access to personal information stored on a smartphone. For example, if you designate your office as a safe location and leave your phone at your desk, anyone can unlock it. Therefore, configure Smart Lock wisely, or better yet, think several times before enabling this function.
Articles and Lifehacks
There are a large number of ways how to unlock your phone. They are in many ways similar for most models of current cellular device manufacturers. This article will outline general principles that help unlock any brand of phone (even if, for example).
The first way to unlock is to enter the PIN code correctly
The most common blocking option is a PIN code forgotten by the user, which must be entered when turning on the device. The best way to get rid of this scourge is to immediately remove the option in the settings when purchasing that allows the phone to constantly display a mention of the code when turned on. If this maneuver with the phone does not work, then, of course, you must write down the code in electronic and paper versions and store them in easy-to-memorize places. But it often happens that it is completely forgotten and it is not possible to restore it with just the work of one’s own memory. Then you need to contact the service center of your telecom operator, which should easily restore the code.
The second way to unlock is to use special programs
A more complex case occurs when a password is used to protect the phone, which only the user knows. If it is forgotten, then this is also no reason to panic. Many models have the ability to connect a mobile phone to a computer. After downloading several small programs from the Internet and applying them to action, almost any model can be unlocked. Such flashing of the device does not subsequently affect the hardware functionality of the mobile phone. In the same way, only with the use of other programs, you can resolve problems with blocking memory cards on your phone.
The third way to unlock is to seek the help of an operator
But how to unlock the phone for those who bought a mobile phone with the condition of connecting to a specific telecom operator without the right to use a SIM card from another. For Russia, this version of the agreements is not particularly relevant, but it also needs to be considered. First of all, you need to call the support service of your telecom operator and find out whether unlocking is possible for this case. If this is unacceptable, then the heavy artillery of the Internet must be used. You need to look for sites where it is possible to get a code using your phone’s IMEI. A lot of them. And most popular brands of phones can be unlocked.
The final way to unlock a mobile phone is to contact a service point
The last unlocking method available is the most frustrating. But in a hopeless situation, he comes up. You just need to take the phone (or, for example, ) to any service point and pay, as a rule, small, but still money. If this doesn’t help, then you are the owner of a unique phone. Feel free to take it to the Polytechnic Museum to preserve it for posterity.
Have you tried to protect the data on your phone with a numeric password or pattern? Now you can't remember your password and use your phone? Such problems lie in wait for many - forgetting identification data, people cannot access the contents and functionality of their devices. How to unlock your phone if you forgot your password? In our review you will find the most detailed and simple instructions to remove the password request.
Here are the main unlocking methods:
- Flashing – new software is uploaded to the phone;
- Hard Reset – reset to factory settings;
- Programs and services from manufacturers - contain built-in unlocking tools;
- Deleting files with passwords and keys - through the file system;
- Holes in security systems – relevant for old pipes;
- Through another user – for multi-user devices;
- Password reset apps are a great tool for many devices.
We will look at all these methods in detail and outline unlocking schemes for phones from various manufacturers.
It's nice to know that some manufacturers take care of the users of the devices they develop by offering additional services. A typical example is Samsung, which created the Samsung Account service. It contains functions for remotely erasing information from Samsung smartphones and tablets, functions for remotely blocking devices, as well as functions for finding them. That is, if the lost device is not found, all important and confidential data can be easily deleted via the Internet.
How to unlock a Samsung phone if the password was safely forgotten? To do this, use the “Find My Phone” function with its sub-function “Unlock my device”. It allows you to restore the functionality of your smartphone or tablet by resetting the screen lock settings. To do this, you need to go to the official website of the service, select the “Find phone” item, make sure there is a connection with the device and click on the “Unlock my device” button. After this, a command to reset the lock settings will be sent to the smartphone/tablet.
In order to take advantage of this functionality, you must first lock your phone/tablet by allowing remote control via Samsung Account in the security settings. In addition, the locked device must be connected to the Internet.
Unlocking a password via Google account
The developers of the Android operating system have taken care to make it easier to restore access to smartphones and tablets if you lose your password. For this purpose, a link to a Google account is provided. It is she who will help us in the matter of restoring access to the contents and functionality of the Android device. How to unlock your phone using your Google account? If you enter the password incorrectly, your phone will be locked for a while. That is, we are given time to remember the ill-fated password.
Temporary blocking also prevents hackers from trying to guess your password. After five attempts to enter the password incorrectly, the phone will prompt us to enter the password for our Google account. We remember the password, enter it in the field that opens - the lock is lifted! Now we need to go to the security settings and reset the password, since we couldn’t remember it.
From this we can conclude that to successfully restore access to your device, you need to know and remember the password for your Google account - write it down and save it in a safe place. This place could be your phone box.
Unlocking with an additional PIN code
Let's get back to unlocking Samsung phones, since we haven't discussed another way to restore access - using an additional PIN code. It is assigned when setting the main security password and includes four digits. Here you need to enter numbers that you will definitely never forget. If you have forgotten the main password, allow several attempts to enter it incorrectly, after which you will have access to the PIN code entry form - enter the treasured numbers and restore access to your phone.
Do not specify too simple digital combinations as a PIN code - this may help attackers gain access to the data stored on your phone. Enter here, for example, the PIN code of your credit card, which only you know.
Unlocking via master reset
How to unlock a password on your phone if all the above methods do not work? You can use a very simple solution - perform a factory reset. The disadvantage of this technique is that all data from the internal memory will be completely deleted(only the contents of the memory card will remain).
How to perform a master reset if access to the menu is blocked? To do this, you need to enter Recovery Mode - this is done using combinations of buttons pressed when turning on the phone. What kind of combinations could these be?
- Both volume buttons and power button;
- Volume up button, home button and power button;
- Volume Down button, Home button and Power button.
There are also many other button combinations that allow you to put your phone into Recovery Mode - look for the corresponding instructions on our website or on specialized forums. After entering Recovery Mode, you need to find and select “wipe data/factory reset”. Having confirmed your intentions, you will start the reboot process, resetting the device to factory settings. At the same time, the previously set password will be deleted.
If you don't want to lose important data, make it a habit to regularly create and save backup copies of your files. Cloud services are also used for this.
Unlocking your phone through flashing
This method is one of the most radical, as it allows you to completely replace the software on your phone. At the same time, the interfering blockage is removed. How to unlock a phone through flashing? To do this, you need to figure out how to flash your phone - look for suitable instructions, download firmware files and programs, charge the battery. After this, we connect the phone to the computer, launch the software, select the firmware files, and perform other operations provided for in the instructions. We start the flashing and wait for the procedure to complete - then we enjoy the absence of blocking.
Flashing phones is carried out using special software, which is selected depending on the handset manufacturer and its model. For example, the Odin program is used to flash phones from Samsung - here owners of handsets from the South Korean giant are very lucky, since the program is very easy, and even an inexperienced user can handle the flashing procedure.
Fly and Sony phones are flashed using the Flashtool application - it’s quite easy, but it won’t hurt to re-read the instructions once again. Chinese phones running on MTK processors (and other handsets with these processors, for example, from MegaFon or Beeline) are flashed using the SP Flash Tool program. There is nothing complicated in it, so in most cases the flashing is successful - you just need to blindly follow the instructions, and not conduct experiments, playing with the program parameters.
Remember that flashing your phone, like resetting it to factory settings, involves complete loss of data stored in the internal memory.
Unlocking your phone through security holes
This method is relevant for owners of very old handsets, where it is very easy to bypass the protection by fraudulent means. A typical example is bypassing a block using a regular phone call. The protection breaks down like this: we call a locked phone from another phone, accept the call, and while making the call, go to the settings and turn off the password request. Next, we drop the call and enjoy the unlocked phone.
This security hole is present on smartphones with the Android 2.2 operating system and lower..
Modern phones don’t have this, so you can’t really rely on this method - but owners of old handsets will be incredibly happy with this method of disabling the lock.
Another hole lies in the process of discharging the battery. At a certain stage, the system will notify you of a strong discharge and the need to connect a charger. At this point we can click on the link to show battery usage statistics. From here we will go to settings and disable the password request. Naturally, this method does not work in modern phones, so you can’t count on it - it’s better to familiarize yourself with other methods that are more effective and efficient.
Unlocking your phone via SMS Bypass
Have you given your phone superuser rights and are enjoying features not available to other users? In this case, you need to take care that you may forget your password - let's try to create a workaround. To do this, we will use the extremely useful SMS Bypass application. Download it, install it in your phone, go to settings and set a digital code - it will serve as the key to unlocking the handset.
How to unlock your phone using SMS Bypass? To do this, you need to send an SMS with the text “XXXX reset” to your number - instead of XXX, enter the previously specified digital code. Having received the SMS, the phone will reboot, after which it will prompt you to enter the password again– enter arbitrary numbers and get an unlocked handset at your disposal.
To obtain root rights, use the instructions on our website or look for a more suitable solution on specialized resources and forums.
Unlocking your phone using codes
Have you forgotten your password and can't use your phone's features? We have already said that resetting the password is done by resetting to factory settings - this is done using Recovery Mode. But what if your phone doesn’t have this mode? Then we try another solution - if when entering a password it is possible to select a keyboard for dialing, you should dial the general reset code on it or the exit code to the engineering menu. Find the corresponding codes on specialized forums and try to use them to unlock your phone.
Do not enter commands whose purpose you do not know - such actions can lead to the most unpredictable consequences, including the complete loss of the phone’s functionality.
Unlocking your phone using Aroma manager
Are you an experienced user, and do you have root rights and custom CWM recovery on your phone? Then you can unlock the handset in one of the most advanced ways. To do this, you will need the Aroma file manager, which should be downloaded to your memory card. Next, turn off the phone and turn it on with the transition to CWM, install the application, go to the system folder /data/system and delete four files there - locksettings.db-shm, locksettings.db-wal, locksetting.db and gesture.key. These files store data about installed passwords and graphic keys.
This unlocking method is available only on prepared phones and only to prepared users. To obtain superuser rights and install custom recovery, use the appropriate instructions. Do not carry out actions or launch programs whose purpose you do not know - this way you will protect your phone from being “bricked”.
Unlock PIN code
How to unlock your phone if you forgot your PIN code? You are given three attempts to enter the correct PIN code.. If all attempts have been exhausted, the phone will prompt you to enter a PUK code - you can find it in the connection kit or request it through your operator's help desk by calling the hotline. After entering the correct PUK code, the phone will unlock and prompt you to assign a new PIN code - save it somewhere safe.
You have ten attempts to enter the PUK code. If all attempts were incorrect, the SIM card will be permanently blocked - you will have to get a duplicate at the nearest communication store. There are no other available ways to unlock your phone if you have forgotten your PIN code.
Unlocking phones on Windows Phone
If your phone runs on Windows Phone, you can unlock it through the operating system's website. By logging in with your username and password, you will find a linked phone in your personal account and will be able to unlock it. This unlocking method works on Lumia handsets and handsets from other manufacturers. Another way to unlock your phone on Windows Phone is to perform a factory reset (useful if you don’t remember your account login and password).
To reset, press and hold the Power and Volume Down buttons until vibration occurs. Release all buttons and press the volume down button again, holding it until an exclamation mark appears on the display. Now press the volume up, volume down, power and volume down buttons in sequence - after a while the phone will reset.
Please note that this procedure involves completely deleting all data stored on the phone - do not forget to make backup copies.
Methods for unlocking phones by brand
How to unlock a Samsung phone if you forgot your password? To restore prepared handsets, you can use the Samsung Account service. If you have not prepared your phone for remote control, try going into Recovery Mode and performing a reset. The last method is to flash the phone via Odin.
In order to unlock your phone from MTS, you can use a general reset or flashing. If your handset has root and CWM, try installing Aroma and deleting the files responsible for blocking. Many other phones, for example from ZTE, Lenovo or Fly, are unlocked in a similar way. And to unlock your Nokia phone, you can use the MyNokiaTool application (for computer).
In order to unlock your LG phone, you should use flashing, general reset or custom recovery with the Aroma file manager. In addition, some LG smartphones assign an additional PIN code that will help you unlock your phone if you have forgotten your password. A similar function is available in many modern smartphones from Samsung.
The most universal way to unblock is to use a Google account - try to learn the password for your account or save it in some safe place. If none of the above helps, contact the nearest service center.
