As soon as you hold the LG K51 for the first time, the most annoying thing is the missing navigation bar.

You find it difficult to go back, close the running apps, or reach the home screen without the home touch buttons.

The default mode of navigation on the K51 is Gestures. To restore the back, home, and recent apps buttons, we need to change the navigation style from “Gestures” to “Buttons Only”.

Factory reset LG K51 lmk500mm -How to soft, hard & master reset

Soft Reset can fix most of the temporary K51 problems such as app crashes, lagging, black screen, overheating, sound issues, charging problems, etc. If the soft reset fails to resolve the issue, try safe mode.

Only when soft reset & safe mode fails to restore your K51, you should go for a factory or hard reset. A factory data reset erases all the internal storage data including apps, games, texts, call logs, media files, etc. You should always create a backup before doing a reset.

In this post, we are going to learn how to reset LG K51, including soft reset, factory reset via Settings app & hard/master reset via the Recovery Mode when locked out –

How to Soft Reset / Force Restart LG K51?

 

A soft reset is the most basic form of troubleshooting on LG K51. It can resolve most of the issues.

lg k51 soft reset

In Soft reset, we turn off & turn on the phone. Also known as a restart.

Long-Press the power button to get the power options on the screen.

Select “Power off and restart” and then “RESTART”.

Wait for the phone to boot again. Check if the issue is gone.

In case your K51 is Frozen – 

lg k51 force restart

When your K51 is frozen, the power button won’t respond. In such a case, we need to force restart the phone.

As K51 comes with a non-removable battery, we cannot force power off by removing the battery. We need to use the combination of volume down & power button to do the same.

Press & hold the Volume Down & Power keys for 10 seconds or until the phone restarts.

Safe Mode 

LG K51 safe mode

If the soft reset failed to fix your issue, use the Safe Mode before resetting the phone.
