How to unlock LG K40 without password/LG K40 Hard Factory Reset Forgot Password/PIN/Pattern

You can see I’m locked out on my LG K40. I want to unlock the screen but I don’t remember the screen lock password.

Unfortunately, we cannot bypass the lock screen without a reset. We need to factory reset the phone (via Recovery Mode) using the volume down & power keys. In this process, your internal storage data including pictures, videos, apps, etc. will get wiped.

To put our K40 into Recovery Mode, we need to power it off.

It’s not letting me power off the phone without unlocking the screen.

There’s an error on the screen – “Unlock the phone to power off”.


So, we are going to force restart our K40.

Press & hold the volume down + power keys until the phone restarts.


During the restart, when the LG K40 logo shows up, release the power key for a moment and hold it again. Don’t leave the volume down button.

Now, keep holding both the keys until you reach the “Factory Data Reset” screen as shown below.


My LG K40 is in recovery mode. The touch doesn’t work in this mode.

Use the volume down button to go down from “No(Exit)” to “Yes”. Now click the power key once.

Repeat the above steps.

Again move down from No(Exit) to Yes and click the power button. The factory data reset will take a few minutes.


After the reset, I’ve reached the “Welcome” page. This is the first page of the setup wizard.

Let’s continue to finish the device setup.

Press the forward arrow to proceed further.




Now, we need to connect our K40 to a Wifi network.

It’s checking for updates, let’s wait for a while.



Choose “DON’T COPY” on the “Copy apps & data” screen.

This will bring you to the screen lock verification page. It’s asking to verify the lock screen password. As I don’t remember it, I clicked on – “USE MY GOOGLE ACCOUNT INSTEAD”.


This brings me to the Google verification screen. To get past this page, we need to sign in with the previously synced Google account on this device.

Enter your Google account credentials and follow the on-screen prompts to reach the LG K40 home screen.

In case, you don’t remember the last synced Google account, then follow the below hack to bypass the Google verification on LG K40 –

How to bypass Google Verification on LG K40 without a computer – No Switch Access 2021


To bypass FRP on LG K40, we need a locked SIM.

I’m using LG Aristo 2 & a Metro SIM to do the job.

If using an LG phone –

Open the Settings app, and choose “Lock Screen & Security” as shown above.


Now, Go to “Set up SIM card lock” and enable the option “Lock SIM Card”.


It’s asking for the current SIM PIN. The default PIN code varies from carrier to carrier. You can search it in Google.

The Default MetroPCS SIM PIN is 1234

Enter the PIN and hit “OK”.

The SIM card lock is enabled.

Now, we are going to insert this locked SIM in LG K40 –

Use a SIM ejector tool to remove your K40 SIM tray and place the locked SIM in its respective slot.

Now, check your K40 screen.

It’s asking for the PIN code.

Enter the SIM PIN 1234 and tap the tick icon.

There is a “Not signed in” notification on the screen.

Swipe down the screen starting from “Not Signed in” towards the bottom of the screen. Follow the arrow in the above screenshot.



This brings a few quick access icons to the top.

Long-press the “Bluetooth icon” to open the Bluetooth page.

Now, turn on Bluetooth and get a Bluetooth headset or Earbud.



I’m using the earbud “PTron BassBuds Urban”.


Pair your Bluetooth device with K40.


Now, tap the touch are of the earbud/call button of the Bluetooth headset for 3 seconds and release it.

This will open Google assistant on the phone.

Now, we are going to use a voice command.

Tap the Mic icon and say the term email

A “G Search” icon appears at the bottom-right corner. Click on it.


Erase the term email from the Google search bar.


Type email once again and choose the “Email app with icon” as shown above.

This will bring you to the “Select Email Provider” screen.

Choose the first option – “Microsoft Exchange”.

Now, enter any email address and click “MANUAL SETUP”.

This time we are on the “Server Settings” screen.

Scroll down on this page and choose the last option to “Add” a Client Certificate.


It says we need to change to a secure screen lock to proceed further.

Tap “CHANGE” to accept the request.

Now, we have reached the “Select Screen Lock” page.

We are going to use this page to add a new PIN, Pattern, or Password.

I’ve picked the first option – “Pattern”.

Choose the option – “Require phone to turn on phone” on the “Secure start-up screen and click “NEXT”.

Now, draw an easy-to-remember pattern. I’ve drawn the pattern L

Make the pattern one more time and hit “CONFIRM”.

The screen lock has been changed. We are all good.

Now, let’s go back and use this new Pattern to bypass Google verification.


Keep going back until you reach the “Welcome” page.


We have reached the “Welcome” screen. Click the forward arrow to proceed.


Tap “DON’T COPY” on the following screen.

After the recent LG K40 update, we don’t get the screen lock verification page after changing the screen lock. We cannot bypass the Google verification without the “Verify Pattern” screen. To restore that page, we are going to hard reset the phone via Recovery Mode. 



To put our K40 into recovery mode, we need to power it off.

Long-press the power button and tap “POWER OFF”.


Once the phone is off, press and hold the volume down + power button to boot the phone.

When the LG K40 logo appears on the screen, release the power button and hold it again.

Don’t leave the volume down key.

Now, keep holding both the buttons until you reach the “Factory data reset” page.


We are in the Recovery Mode.

Move down from No to Yes and click the power key once.


Again go down from “No(Exit)” to “Yes” and tap the power key to begin the factory data reset. This process will take a few minutes.


After a while, I’ve reached the Enter PIN Code screen.

Enter the code 1234 and unlock the screen as shown above.


Now, click the forward button to move ahead.

Tap “DON’T COPY” on the following screen.


This time it brings us to the Pattern verification page.

Verify with the pattern L as shown above.

The Pattern verification was successful. We have bypassed the Google verification.

Use the “Skip” option on the Google sign-in page to proceed further.



Now, accept the Google services terms and conditions.


Click “NO THANKS” to skip the “Review Additional Apps” screen.


We are now on the last page of the setup wizard.

Tick the “I agree” checkbox and hit “DONE” to complete the setup wizard.

We have successfully reached the LG K40 home screen by doing a hard factory reset.
