LG K31 Rebel Hard Factory Reset without password,PIN L355DL

When you’re locked out on your LG K31, you’ll try to hard reset the phone to restore it back to the working state. To access the recovery mode, we need to turn off the phone.

However, on K31, it doesn’t let you power off/restart the phone without unlocking the screen. So, how to reset the phone without knowing the correct password/PIN/Pattern?

Let’s find out with the help of the below troubleshooting guide –

I’m stuck on my LG K31 lock screen. I want to unlock the screen but I don’t remember the correct password.


After multiple failed attempts only the wait time increased. We don’t get any account recovery option in the form of  “forgot password”.

So, now let’s try to hard reset the phone via recovery mode.


To access the recovery mode, we need to turn off the phone.

It’s not letting me power off my K31. The screen shows an error – Unlock the phone to power off.


The same thing happens when you try to restart the phone.


Our last option is a force restart.

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



During the reboot, as soon as the LG logo appears on the screen, release the power key for a moment and hold it again. Do not leave the volume down button.

Now, keep holding both the buttons to reach the Recovery Mode.


In recovery mode, the touchscreen doesn’t work. We are going to use the volume rocker and power keys for navigation.

Use the volume button to move down from No(Exit) to Yes. Now select the “Yes” option with the power key.



Again go down from No to Yes and click the power button to begin the factory reset.

The hard reset takes a few minutes.

Afterward, it brings us to the “Welcome” page. This is the first screen of the setup wizard.

Let’s tap the forward button to begin the device setup.

Hit “Next” on the “New Second Screen” page.


Now, connect your K31 to a Wifi network and click “Next”.

The phone stays on the “Checking for updates” screen for a while.


After a few minutes, we reach the “Copy apps & data” page. Choose “Don’t copy” to move ahead.

Now, it brings me to the screen lock verification page. I don’t remember the password so I clicked another option “USE MY GOOGLE ACCOUNT INSTEAD”.


This time I’m on the Google Verification page. To get past this screen we need to verify with the previously synced Google account on this device.

Enter your Google account credentials and follow the on-screen prompts to finish the device setup & to reach the K31 home screen.

In case, you don’t remember the Google account details, follow the below hack to bypass the FRP lock  –

To bypass the Google account, we need to use the keyboard.

Tap the blank field “Email or phone” to pull out the keyboard.

Now, hit the small keyboard icon at the bottom-right corner.


A “Default keyboard” window shows up at the bottom. Choose the “Settings” option to proceed.

This will bring you to the “Manage keyboards” screen.

Select the first option “Gboard”.


On the Gboard Settings page, click the “3 dots” icon and choose “Help & Feedback”.



This will bring you to the Support page.

In the search bar type delete and wait for the search results to appear.

Choose the first search result – Delete or disable apps on Android”.


On the following page, look for the link – “Tap to go to Application settings” and click on it.

This brings us to the “App Info” screen. Scroll down and select “Google” as shown above.



On the Google – App Info page, choose “Open” to launch the Google app.

Click “NO THANKS” to access the search bar.

Enter the term “Chrome” in the search bar and choose the “Chrome app with icon” to launch this app.

Setup the chrome app to view the search bar.


In the Google chrome search bar, search for the phrase – quick shortcut maker apk


Open the first search result and download the apk file.



Download and save the apk file.


Once the file is downloaded, tap “Open” to install this app.


We need to allow the installation from unknown sources to proceed further.

When the Chrome pop-up appears, tap “SETTINGS”.

Now, enable the option – “Allow from this source”.


Now, click “INSTALL” to install the QuickShortcutMaker app.

Hit “OPEN” once the installation is done.


We’ve launched the Quickshortcutmaker app.

Scroll down and click on “Lock Screen Settings”.



Now, select the “Lock Screen Settings” with the “Secure Lock Settings” option.

Click “Try” to open the Secure Lock Settings page.


We are now on the “Secure your phone” screen.

Let’s use this page to add a new PIN, Pattern, or Password.

I’ve picked the PIN option.



Enter the PIN twice and tap “OK” to confirm.


A confirmation text appears at the bottom – “Screen lock has been changed”.

We are all good. We have successfully replaced the old screen lock with this new PIN.

Let’s use PIN  1234 to bypass the Google verification.


Use the back button to reach the first page of the setup wizard.


We are once again on the “Welcome” screen.

Tap the forward button to move ahead.

Click “Next” on the following page.


Connect your K31 to a Wifi network and click “Next”.


Choose “Don’t copy” when you reach the “Copy apps & data” screen.

Now, it brings us to the screen lock verification page.

Enter the PIN 1234 and tap “OK”.

NOTE: If you don’t get the “Verify PIN” option, hard reset the phone once again using the volume down + power button. After the reset, you’ll get the “Verify PIN” screen.


The PIN verification was successful. We have successfully bypassed the Google account verification.

Use the “Skip” option to bypass the google account sign-in.


Now, we are on the Google services page. Accept the Google services terms and conditions.


The last page of the setup wizard is the “Legal Documents” page.

Tick the “I agree” checkboxes and hit “Done” to complete the setup wizard.


We have successfully landed on the LG K31 home screen by doing a factory reset without the password.
