You can hard reset the LG K51 smartphone to wipe all data and reset it to its factory settings. Some people also choose to install custom firmware and must hard reset before swapping stock Android for custom ROMs. There are generally at least two ways to hard reset given its importance for troubleshooting. Most people should hard reset using the Settings app. However, you can also hard reset from Recovery Mode. Though rare, if the Android oeprating system were to become unresponsive, you can boot to the recovery partition. And from recovery is where you can hard reset.

This tutorial demonstrates how to hard reset the LG K51 smartphone.

Caution:
Hard resetting the LG K51 smartphone will wipe all data. You need to take a backup before you hard reset if you want to restore your data later. Some phones have automatic backups turned on. If you do not know if you have automatic backups, make sure you take one manually. You can back up from the Settings app by typing “Backup” in the search field. If you have a custom recovery, you can take a NANDroid backup from Recovery Mode instead.

You can hard reset the LG K51 smartphone using the Settings app or Recovery Mode. We recommend using the Settings app unless you have a specific reason for using Recovery Mode such as unresponsive software or flashing custom firmware. Here is how to hard reset the LG K51 via the Settings app first:

  1. With the LG K51 turned on, open the phone’s Settings app.
  2. Tap General > Restart & reset.
  3. Tap Factory data reset > Reset phone.
  4. Tape Delete all.

You can also hard reset the LG K51 in Recovery Mode. There are two recovery partitions you may have: a stock or custom recovery. Most people have a stock recovery which is for stock Android; however, those who install custom firmware will have a custom recovery installed. The way to hard reset varies between the two. Here is how to hard reset the LG K51 using the stock recovery first:

  1. With the LG K51 turned off, press and hold the Power + Volume Down buttons simultaneously until Recovery Mode boots.
  2. From the Factory Data Reset screen, press Yes.

The LG K51 will be factory reset.

You can also hard reset from a custom recovery image such as TWRP. Here is how to hard reset with TWRP:

  1. With the LG K51 turned off, boot to TWRP by holding the Power + Volume Down buttons simultaneously until you see TWRP.
  2. Tap Wipe.
  3. Wipe the data and all available caches.
  4. Tap Reboot from the main menu.

The LG K51 will be factory reset and all caches will be wiped, meaning it is ready to have custom firmware flashed.
