My phone is blocked, what should I do? Unlock using ADB. Unlocking Sony Ericsson

Locked your phone with a password and forgot it? We will tell you how to remove the blocking.

Navigation

Today, cell phones have become not just means of communication, but also custodians of important data that must be kept safe from third parties. Therefore, people often lock their devices and set passwords. But in the everyday rush, you can forget the required combination. In addition, a child may accidentally set the password.

By the way, the SIM card may be blocked, which is why you will have to think about how to unlock the phone. This issue is especially relevant, which is why manufacturers often build self-unlocking capabilities into their products. But first you need to understand what kind of blocking is installed and what exactly is blocked, but first things first.

What to do if the operator has blocked the phone?

This type of blocking is used by cellular companies to prevent the client from using a phone with a SIM card from another company. If you install a SIM card from another company, the phone will ask you for an unlock code.

Of course, it’s good if your operator is kind and will provide the code upon first request. To do this, call the support service and dictate the IMEI of the phone.

But in this way codes are provided in very rare cases.

If the operator refuses you, then do not be upset, since there are many craftsmen who know how to change the firmware for the purpose of unlocking. Instructions are often found on the Internet, so even if you have a small set of knowledge, you can cope with the task yourself.

How to unlock a phone of a certain brand?

Most modern devices have a password protection feature. The user sets the code independently. But there is always a risk that the password will be forgotten and this will lead to the inability to use the device. In this situation, try changing the firmware. That is, reset all settings to factory settings. Of course, then you will have to make the settings again “for yourself,” but there is no other option. Each manufacturer has its own type of unlocking.

Unlock Nokia

For the procedure you will need:

• Computer
• Telephone cable
• Nokia PC Suite
• Nokia Unlocker Tool

Launch the first program and connect the device to the computer. When it is recognized, launch the second application. After this, the phone should be recognized by Nokia Unlocker Tool. Request a code and the program will unlock your device. If the method does not give any effect, then only a professional will help you.

Unlocking Sony Ericsson

For this manufacturer, there are two methods for unlocking - through a cable and a special service cable. For the second option, you will need to install SEMCtool_v8.4 or TMS 2.45. If you use a standard wire, then install WotanClient, but it is paid. The DaVinci client is suitable for some types of smartphones.

Unlock Samsung

Smartphones of this brand also have the ability to be locked with a code that is very easy to forget. If you find yourself in this situation, then install the Samsung @ home 9.41 program on your computer. It easily fixes the problem. The utility is very easy to use and therefore you can configure it without difficulty.

Unlock LG

This manufacturer is somewhat different from others. If your phone is locked, you need special unlock codes to restore it. The difficulty is that each model has its own, so you only have to contact a repair shop.

How to unlock a SIM card?

To protect the information stored on the SIM card, a PIN code is used, which is requested when the device is turned on. If you enter it incorrectly three times, the phone will ask for a PUK code. It has 8 digits and is issued with a SIM card. If you have forgotten your PIN code, but have a PUK code, then use it.

The most important thing is to understand what and why you are doing. Otherwise, you can break the gadget and then you will have to spend money on repairs or a new device.

A password that protects entry to a personal smartphone or tablet from outside intrusion is called a graphic key. It does not consist of numbers, but of nine circles (dots) that need to be connected in a certain sequence. Often, gadget owners forget the key, so they don’t know how to remove it.

Remove pattern using Google account

There are several standard options for unlocking a pattern key. The easiest way is using a Google account. To unlock your electronic device, repeat the step-by-step instructions:

1. Make five attempts to enter the key, but since the figure is drawn incorrectly, the device will be blocked.
2. Next, the message “Forgot your pattern key?” will appear on the screen.
3. After clicking on it, you will be asked to sign in to your Google account, after which access to the device will be allowed.
4. This method will work if the device is connected to the Internet, and also if you remember your details (username and password) to log into your Google account.

Reset

On a new phone (tablet computer), unlocking the pattern key will be “painless” if you use a reset of all settings. Please note that if the device has been in use for a long time and there is a lot of personal data stored in it, then using this method you will lose it. How to reset settings on an Android mobile device:

1. Remove the MicroSD to save the information stored on the flash card.
2. With the device turned off, simultaneously press one of the combinations: a) volume up button + power off/on key; b) volume down button + “Power” key; c) increase volume + decrease volume + “Power”, d) increase volume + decrease volume.
3. After 5-10 seconds, the engineering menu of the recovery mode will appear. Using the volume button, select the “wipe data/factory reset” option, and then press the power key.
4. Next, in the window that opens, there will be the necessary item “yes - delete all user data”. Then find “reboot system now”, after which the device will reboot and unlock.
5. This entry into recovery mode is universal for many mobile devices running Android.

Phone call

You can reset the pattern key on Android after calling from another number. This method is suitable if you have an operating system (OS) version of 2.2 and lower. To remove the key from Android, do the following:

1. Ask to call your number from another mobile device.
2. Answer the call, then remove the call window and press the Home key.
3. The device will be unlocked, then go to Settings.
4. Next, select the “Security” section in the menu, and then delete the graphic password.

Smartphone discharge

You can remove the key from Android after your smartphone or tablet is discharged. Wait until the battery drains (less than 10%), then do the following:

1. During the notification that the battery is low, click on it, then go to “Settings” - “Security” - “Lock”.
2. Remove the picture password. It is important to do this before the phone turns off.

Using File Manager

You can remove the key from Android using a file manager, but this method will work on gadgets with a modified recovery menu (CWM or TWRP). You can remove the key without unlocking using the following steps:

1. Download the Aroma Filemanager archive file.
2. Move it to your device's memory card.
3. Find the recovery menu (initial steps using the “factory reset” method) and install the utility.
4. Select “Choose zip from external sdcard” (“Choose zip from sdcard” or “Install zip from sdcard”), go to the folder with the archive of the AROMA Filemanager program, download it.
5. Then go to the “/data/system” folder, from which delete the files: password.key, gesture.key (Android version 4.4 and lower), getekeeper.pattern.key, getekeeper.password.key (Android version 5 and higher).
6. Then restart your mobile device, then enter any unlock gesture.

ADB program

If you cannot get to the recovery menu to reset the settings, then you should use the ADB program. This is a console application designed to work on a computer, but allows you to perform different actions on Android devices. The utility cannot be downloaded because it is part of the Android Studio package. This method will only work on devices that have USB debugging enabled in the "For Developers" section. It can be activated when connected to a computer via a cable. How to download and install the ADB program:

1. Download the Android Studio application to your computer from the official website. Using the archiver, open and then enter the “$TEMP” folder. After 2 times click on the “android-sdk.7z” option and extract the “platform-tools” folder.
2. Move it to the root directory of drive C “SystemRoot%”, rename it.
3. Connect your mobile device to your computer via USB and install the driver.
4. If it is not there, then download the universal Google USB Driver from the Google Play Market and use the “Control Panel” - “All Controls” - “Device Manager” tabs to install it on your computer.
5. After installing the driver, open the Command Prompt program using the Win + R keys, enter the cmd command into the line and click OK.
6. To remove the graphic key, go to the folder with the program, then enter “cd c:/adb” in the command line and confirm the action by pressing “Enter”.
7. Afterwards, the Android smartphone (tablet) needs a reboot.

Service center services

If you can’t remove the graphic password yourself or you are not confident in your abilities, entrust your gadget to the service center employees. Masters have the necessary software and can use any of the above schemes, but with 100% results. The service is paid, but this action will help you save on repairing your mobile device, because if you intervene on your own, you can easily damage your gadget.

Android? Don't worry, there are several ways to regain access to your mobile device. In this article you can find the main options for resetting the lock, both the simplest and more complex ones that require additional programs. One of these methods will definitely help solve the problem with a locked phone.

Account details

A simple way to unlock Android if you forgot your password is to restore access using your Google account. This method will only work if the tablet or phone is connected to Wi-Fi or a mobile network. This is a mechanism of the system itself that helps in the event of an incorrect password or pattern.

If you enter the pattern incorrectly more than five times, a window will appear warning you about a thirty-second block. The message “Forgot your pattern key?” will appear on the device screen, and when you click on it, you will be asked to enter your Google account information. After you enter your email address and password, the device will unlock.

If you have forgotten your account information, you can restore it on the official Google website.

If there is no Internet connection

The first method, showing how to unlock an Android if you forgot your password, will not work if there is no Internet, since the login and password for your Google account will be impossible to verify. An Internet connection must be established.

To do this, you need to turn it on and off or simply restart the device. Immediately after turning on, the top bar will appear (it is also called the notification center, or information center). Pull it down and turn on Wi-Fi or mobile Internet. After this, you can enter your username and password, and the device will be unlocked.

If there is no Wi-Fi nearby and mobile Internet is not available on your SIM card, you can do the following. Just use a different SIM card, pay attention in advance whether the Internet service is connected and whether there is money on the balance.

You can also connect the device to the Internet using a LAN adapter. To do this, you will need the adapter itself and a router connected to the Internet. The device connects to the Internet using an adapter, which will allow you to check the correctness of the entered Google account data.

Wait until the battery runs out, the device will notify you about this. Then you can enter the power status menu, from there go to the main menu and disable protection using the pattern key.

Disabling the lock via computer

The fifth method will work if enabled. This function can be enabled in the “For Developers” menu. If it was enabled before blocking, then disabling the graphic key protection will be easy.

The program will offer a choice of two options: method 1 and method 2. The first method deletes the gesture.key file. The second method removes data from the system.db file. Choose one of the methods. The device will be unlocked, all that remains is to reboot it.

Unlocking via Recovery menu

Several methods for unlocking a pattern key are based on manually deleting the gesture.key file. To use these methods, your device must have a Recovery menu.
