Frequently asked questions
Will a hard reset delete everything on my Samsung I9100G Galaxy S II?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung I9100G Galaxy S II to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Samsung I9100G Galaxy S II 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 Samsung I9100G Galaxy S II?
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 Samsung I9100G Galaxy S II?
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 Samsung I9100G Galaxy S II 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 Samsung I9100G Galaxy S II?
Use the Hard Reset method above if your Samsung I9100G Galaxy S II 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.
Does my Samsung I9100G Galaxy S II have a hard reset button?
Not a single dedicated button — the Samsung I9100G Galaxy S II uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
