Why reset your LG K31?
A hard reset on the LG K31 fixes boot loops, forgotten PINs and persistent lag. Using Volume Down + Power, you can access recovery mode and wipe the device back to factory condition. Always back up your data first, as a reset cannot be undone.
Frequently asked questions
Will a hard reset delete everything on my LG K31?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the LG K31 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the LG K31 remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the LG K31?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Will I need my Google account password after resetting the LG K31?
Yes, if Factory Reset Protection (FRP) is enabled. Android (and HarmonyOS 2.x devices with Google services) will ask for the last signed-in Google account after a reset — make sure you know that password first.
Can I factory reset my LG K31 without the password?
Yes — resetting through recovery mode doesn't require your lock screen password, since it bypasses the login screen entirely. That said, Factory Reset Protection may still ask for your Google account credentials afterward as an anti-theft measure.
How do I reset my LG K31?
Use the Hard Reset method above if your LG K31 is frozen or won't respond, or the Factory Reset method if the screen still works normally — both are covered step by step on this page.
How do I format my LG K31?
"Formatting" and "factory resetting" mean the same thing for the LG K31 — both erase all data and restore default settings. Use whichever method above matches your situation.
