Why reset your LG G4?
A hard reset on the LG G4 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 G4?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the LG G4 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the LG G4 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 G4?
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 G4?
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.
How do I format my LG G4?
"Formatting" and "factory resetting" mean the same thing for the LG G4 — both erase all data and restore default settings. Use whichever method above matches your situation.
Can I factory reset my LG G4 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 G4?
Use the Hard Reset method above if your LG G4 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.
