Frequently asked questions
Will a hard reset delete everything on my LG Optimus 3D Cube SU870?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the LG Optimus 3D Cube SU870 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the LG Optimus 3D Cube SU870 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 Optimus 3D Cube SU870?
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 Optimus 3D Cube SU870?
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.
Does my LG Optimus 3D Cube SU870 have a hard reset button?
Not a single dedicated button — the LG Optimus 3D Cube SU870 uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
How do I format my LG Optimus 3D Cube SU870?
"Formatting" and "factory resetting" mean the same thing for the LG Optimus 3D Cube SU870 — both erase all data and restore default settings. Use whichever method above matches your situation.
Can I factory reset my LG Optimus 3D Cube SU870 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.
