Resetting the lock using the application
Finally, the tenth and last method of resetting the pattern. This method is simple, but to use it you should think in advance about how to unlock your Android if you forgot your password. That is, in fact, even before the blocking itself. Root rights are required to use.
Download and install the application SMS Bypass, allow him to use Root rights. Now, to unlock your smartphone, you just need to send a message to it with the text “1234 reset”. You can change the text yourself.

Without exception, all TV models have a locking function. Sometimes it is needed, for example, if there are children in the house and they are used to using the remote control, which they do with pleasure, forgetting about lessons and simple children's games. It's difficult to keep them away from the screen without blocking the TV. But it happens that even having a password does not help, because the lock can be removed. Then the parents come up with a more complex PIN code, but manage to forget it.
What to do in this case? Either don’t watch your favorite TV shows at all, or try to figure out the problem. Of course, you can call a technician, but TV owners are confident that they can handle the situation without anyone’s help. This happens quite often. But if you see that nothing is working out, it is better to call a professional.
How to understand that the TV is blocked
If you did not specifically install the block on the TV, then this happened by accident. Perhaps the children pressed a free key combination, and therefore the device died, or the system itself began to glitch, which is why the block was installed. There may be many reasons, but you can’t leave everything as it is either.
How can you understand that the LV device is not broken, but there is a block on it? It’s very simple, because on any TV the presence of a block is accompanied by one of these signs:
Nothing is visible on the screen except the blue background and the key pattern. There is no sound or picture of broadcast programs;
Instead of the expected image, the monitor shows a password entry field;
Only one channel works on the TV, and the device does not respond to attempts to switch it with the remote control remote control or on the panel of the TV itself.
In general, the signs are clear, so it is quite difficult to confuse the presence of a block with some other problem. However, if you know what password is used, the situation can be resolved simply. If you don’t know him, and the blocking happened by accident, then only a very lucky person can guess this arbitrary combination of numbers.
When you have problems with luck, you will have to use other methods that will help if you forgot the password on your LG TV or didn’t know it at all.
Causes of malfunction and how to neutralize them
There are a lot of troubleshooting options, but the most popular are the following:
Use the remote control by pressing it special combination keys True, you still need to know this combination, because different manufacturers TV often use non-standard instructions. Although if you are sure that you have not made any changes, you can always try the combination 0000. It is standard for most models. If it doesn’t help, there is an alternative, albeit not so popular among manufacturers - press combination 1234;
It happens that the TV is working and no one pressed the remote control, but when the device turns on, it does not work, and a message flashes on the screen indicating that you need to enter a password. Most likely, the issue is that you need to configure the channels. In this case, try new search TV channels, and they will restore their broadcasting;
If we're talking about about Smart TV, then the issue may be outdated software. The system reacts in this way to an increased number of errors that block the system, including the broadcast of channels. To correct this flaw, you urgently need to update software online or using a flash drive.
Both of the latter options are much less common than the first, but if entering a password or resetting it to factory settings does not help, then it makes sense to check both latest methods to restore broadcasting.
How to unlock LG TV
Even if the TV owner has never encountered a blocking problem and has not used the block, he may need to remove it. But how to do this if the principles of action are unknown. If so, then you need to take the instructions. As a rule, this piece of paper can help significantly, because it indicates standard passwords, as well as how and in what order to use them.
If there are no instructions, then you can find them on the Internet if you know the TV model. You can view it on the back of the TV. Then download it and use it. In addition, you need to take a remote control, preferably the one that came with the TV, or something similar.
So, the instructions indicate special set numbers that are pressed to remove the restriction on channel search. In addition, the block can be removed by pressing a button with a drawn key on the remote control. This button must be pressed and held for ten seconds, and then the password is either removed or reset to the factory default.
How to reset your PIN to factory default
If you remove the child lock from the TV standard methods If it didn’t work, you can move on to drastic methods, which include resetting the settings to factory settings. You can do this on LG TV by following these steps:
Open the menu and select “Settings”;
Go to the “Security” section;
Further password reset consists of selecting the “Reset PIN code” menu;
But this is also not enough. After this path has been completed, the following manipulations should be carried out:
Enter the password numbers incorrectly and click on confirm (Ok);
Consistently press the following combination: Up - Up - Down - Up;
Enter code 0313 and click “Ok”.
After this, you can check whether you succeeded in resetting the password. This is desirable, since it is necessary to clarify whether the procedure was successful. If everything went well, then whatever the password was before, it will now become standard, and to remove the block you need to enter four zeros.
Here's another way to reset your password:
For keypad:
You need to enter the settings menu;
There is a blocking subsection and the user should click on it;
During the process, a window will pop up where you need to enter a password;
You need to enter not standard values, but combination 0325;
Click on POWER button and turn off the power;
Be sure to press POWER to turn on the power. How to change the password on LG TVs
To change the password on LG TVs without having to try to reset the pin along with resetting all settings to factory settings, you can use the following method:
If, after completing these procedures, the situation has not changed, it means that the child who set the password turned out to be a much more sophisticated user than his parents. In this case, it is better to stop experiments and turn to a TV technician for help. Thanks to his services, the TV will start working normally with almost a 100% guarantee.
Too many attempts to enter the pattern key lg 136, e612, e615, lg2, p705, k7 e612, lg magna, p970, e612, p765, l90, lg leon, bl t23, e612, e615, lg bl 59jh and so on, of course incorrect cause the phone to be blocked.
How to unlock? There is such a possibility. There are several ways to remove a pattern lock on an LG phone.
It is possible with data loss, it is possible without loss, only with the preservation of information, you must remember the password for Gmail.
If you forgot it, then you can disable the pattern lock on LG only by resetting it to factory settings, while the phone must be turned off and charged.
In general, I will describe three methods. For the first two (with data saving) your lg android must have internet, without it don’t even try
If there is no network, you can connect it. To do this (there are three options, whichever one must connect to the Internet)
The first way to reset the pattern key in your lg phone - if you forgot
If the phone is locked with a pattern key, then dial it incorrectly five times using at least 4 dots.
Click on it and begin to bring the phone to normal life. To do this, enter your gmail account information, after which you can easily remove the pattern key to unlock your lg.
Then you can turn off the lock or select another pattern, only this time try not to forget.
The second way to unlock the pattern key in your lg phone is if you forgot it
For this method, in addition to the Internet, you need a computer or laptop. If there go to this page.
Now we enter the account information, after which the service should show your lg phone in the top left. There may be several, then choose yours.
Below the phone there will be three options: “call”, “unblock” and “delete”. I don’t think there’s any need to explain which one to press.
The graphic key can also be removed by clicking on “Delete”, only then will your data be reset along with the key - so click on “Unlock”.
The third way to reset the pattern on your lg phone
Here the first steps are not exactly defined, since everything depends on the lg phone model, but the principle is this.
Turn off your smartphone completely, then simultaneously press and hold a certain combination of buttons until the menu appears.
In some LGs, press and hold both the volume buttons and the power button simultaneously for 3-4 seconds.
You will see the android image. Using the volume buttons select recovery mode and press the on/off button to confirm.
The device will reboot and display Android with a red triangle. Press and hold the Power button for a few seconds and increase the volume until the menu appears.
Go to the menu, select - wipe data/factory reset, press the "Yes" button using the volume button and confirm the choice by pressing the power button.
D LG L3, LG L7 - simultaneously press “Home” + “Volume down” + “power (off)”. In LG Optimus Hub - press volume down, home and power at the same time.
I hope these instructions helped you unlock Android phone lg. If not, write the model in the comments and I will try to answer as soon as possible. Good luck.
All mobile device manufacturers provide the opportunity to protect user data in a variety of ways. There is no doubt about the usefulness of such a function, but there are cases when the owner of a smartphone simply forgets the unlock code. We will tell you exactly how to unlock an LG smartphone in this manual.
Actually, there are several ways to unlock the screen, one of which, sad as it may be, will lead to the loss of all data located on your device.
When installing Knock Code, graphic key or face control, you are additionally asked to enter a PIN code or password to unlock them. If you remember them, then there will be no problems. We strongly recommend not to forget it or just write this set of numbers somewhere in a notepad. If you don’t remember it, then unlocking your LG phone if you forgot the password will be more difficult, but this task is still doable.
Method 1 – Unlock LG pattern using Google account
If you are unable to enter the lock code and password correctly, but at the same time you perfectly remember the account data, then we repeat the entry attempts until the “forgot...” button appears. Click on this button and a window for entering data from your Google account will appear on the screen. You need to enter an address Email and login password. This method will allow you to unlock the screen only if your smartphone has an active connection via Wi-Fi or mobile Internet. If this method does not work, then the only thing left is radical method which is described in the next paragraph.
Method 2 – full reset settings ( Hard Reset)
If you don’t remember any data from your accounts and passwords, then you can remove any lock by resetting the settings, called Hard Reset. It is worth noting that when using this decision all data will be deleted from memory mobile device and the system will be brought to stock condition(with saving current version operating system). Just in case, remove the SIM cards and memory card. The reset procedure is almost the same for all LG smartphones.
We perform the following steps step by step:
- Turn off the device.
- Simultaneously press and hold the “Power” and “Volume Down” buttons until the company logo appears, then release the “Power” key and immediately press it back. (Some models require you to press both buttons and press them again)
- A confirmation window will appear to reset to factory settings.
- Using the volume rocker, select the “Yes” button and confirm the selection with the “Power” button. If a second confirmation request appears on the screen, then do the same.
That's all. After resetting the settings, you will need to perform the same actions that you did after purchasing the smartphone.
