Use Android Device Manager

If your LG phone is linked to a Google account, the fastest way to unlock it is using Google’s Android Device Manager.

This free web portal allows you to remotely ring, lock, or erase your lost or misplaced Android device. Conveniently, it can also reset your lock screen password if you forgot the PIN, pattern, or passphrase.

Here’s how to use Android Device Manager to unlock an LG phone:

Lock on Android Device Manager
  1. On a computer, go to
  2. Sign in with the Google account associated with your locked LG phone.
  3. On the map, locate your phone and click on it.
  4. Select Lock from the menu.
  5. Enter and confirm a new password for your phone’s lock screen.
  6. Click Lock and your phone will be remotely updated with the new unlock password.
  7. On your LG phone, enter the new password to unlock it.

The whole process only takes a few minutes, and you can avoid factory resetting your device this way. Just make sure your LG phone stays powered on and connected to the internet during the process.

If you don’t have a Google account on your phone, try the next method using your LG account details.

Unlock With Google Account

For older LG phones running Android 4.4 KitKat or earlier versions, you can unlock your forgotten screen lock by signing in with your Google account. Here’s how it works:

How to Unlock LG Phone Forgot Password with Google Login
  1. Attempt to unlock your LG phone until you see the “Forgot Pattern?” button.
  2. Tap Forgot Pattern?.
  3. Enter the email and password for the Google account tied to your phone.
  4. After signing in successfully, your lock screen will be disabled.

This simple process allows you to bypass the forgotten PIN, pattern, or password by proving you’re the owner via your Google account.

Unfortunately, it no longer works on new LG phones with Android 5.0 or later. But it can be a handy trick for older devices if you still use your original Google account.

Unlock With SD Card

If you have an SD card in your LG phone, you may be able to unlock it by using a special app to disable the lock screen.

This method involves installing a lock screen removal app from the recovery menu when booted into custom recovery mode. Here are the steps:

What You’ll Need

  • SD card for your LG phone
  • Custom recovery like TWRP installed on your phone
  • Pattern Password Disable ZIP file (download here)
  • Computer with SD card reader

Steps to Unlock

Unlock LG phone using custom recovery
  1. Insert SD card into computer.
  2. Copy the Pattern Password Disable ZIP to the SD card.
  3. Restart your LG into recovery mode:
    • Power off the phone
    • Hold Volume Up + Power until recovery menu loads
  4. Select Install in recovery mode.
  5. Navigate to the ZIP file on your SD card.
  6. Install the Pattern Password Disable app.
  7. Reboot your LG phone normally.
  8. The lock screen should now be disabled so you can access your phone.

This SD card method works by overwriting the lock screen files when booted in recovery mode. The only catch is that custom recoveries like TWRP must be installed ahead of time.

But if you have a removable SD card and recovery access, it’s worth trying before factory resetting your LG.

Factory Reset in Recovery Mode

If all else fails, performing a factory reset from recovery mode can force your LG phone to reboot without a lock screen.

However, this will erase all data on your phone. Only use this method as a last resort if you have no other options.

Here are the steps to factory reset an LG from recovery mode:

wipe data/factory reset
  1. Power off your phone completely.
  2. Restart into recovery mode:
    • For most LG phones: Press and hold Power + Volume Down until the LG logo appears.
    • For other models: Research the key combo to enter recovery mode for that device.
  3. Use Volume keys to highlight Wipe data/factory reset.
  4. Press Power to select it.
  5. Confirm you want to erase all user data when prompted.
  6. Wait several minutes for the factory reset process to complete.
  7. Highlight Reboot system now.
  8. Your LG will restart without a lock screen, ready to be set up fresh.

Factory resetting from recovery can bypass a forgotten PIN or pattern lock. But only use it as a last choice since you’ll lose all local data.

Unlock With ADB Commands

If you enabled USB debugging before forgetting your password, you can use Android Debug Bridge (ADB) to unlock your LG.

ADB is a developer command line tool that can control Android devices over USB. Here’s how to use it to reset your lock screen:

What You’ll Need

  • LG phone with USB debugging enabled
  • Windows, Mac, or Linux computer
  • Android SDK platform-tools installed

Steps to Unlock

Download and install Android SDK platform-tools on your computer.

Connect your locked LG phone via USB.

Open a command prompt/terminal and enter:

Authorize your computer on the prompt if it appears on your LG phone.

Enter these ADB commands:

Update the lock value:

Close command prompt and reboot your LG phone.

Try entering a random PIN/pattern to unlock.

With ADB, we’re resetting the lock database values to disable the screen lock. You’ll need some comfort with the command line, but it’s handy for advanced users if enabled beforehand.
