LG K51 lock screen bypass – forgot password, pin, pattern /locked out

There are 4 kinds of screen lock on LG K51. The primary locks are Password, PIN & Pattern. Fingerprint can be set as a secondary lock. K51 lacks face unlock/face recognition.

If you’ve forgotten the primary screen lock, it won’t let you power off or restart the phone without unlocking the screen. So, what are your options if you’ve forgotten the password, PIN, or pattern on your K51? Can we bypass the lock screen without reset/losing the internal storage data?

Let’s check out our options –

How to bypass LG K51 lock screen without reset

After 5 failed attempts, it allows me to try again after a wait time of 30 seconds.

Even after 20 wrong attempts, I didn’t get any kind of recovery option such as “Forgot Password” or “Google Account Recovery”.

I kept on trying but only the wait time increased after every few failed attempts.

So, one thing is clear. We cannot bypass the LG K51 lock screen without reset.

Now, let’s try to reset our K51.

To Reset the phone using hard keys (Volume Down & Power Button), we have to Power off the phone.

It’s not letting me power off the phone. It says “Unlock the phone to power off”.

Let’s try to restart the phone.

It’s not allowing me to even restart the phone.  Again it shows a similar error “Unlock the phone to restart”.

Now the only option left is to wait for the battery to die down or to Force Restart the phone.


Without wasting time, let’s force restart our LG K51 –

This is a crucial step. Follow it closely.

To Force restart your K51, Long-Press, and hold the Volume Down & Power button until the phone restarts.

A countdown window pops up at the bottom of the screen – “To restart, press and hold both keys for 4 seconds”.

As soon as “LG K51” appears on the screen (or when the phone vibrates), release the power button and hold it again until it takes you to the Factory data reset screen. 

Keep holding the volume down button during the whole process.

The above factory data reset screen is also known as the recovery mode. The touchscreen is disabled in recovery mode.

We have to use the volume rocker to move up /down. You can select an option with the Power button.

Use the Volume down button to move from “No (Exit)” to “Yes” and press the Power key to select this option.
