Frequently asked questions
Will a hard reset delete everything on my Samsung I9105 Galaxy S II Plus?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung I9105 Galaxy S II Plus to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Samsung I9105 Galaxy S II Plus 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 I9105 Galaxy S II Plus?
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 I9105 Galaxy S II Plus?
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 Samsung I9105 Galaxy S II Plus have a hard reset button?
Not a single dedicated button — the Samsung I9105 Galaxy S II Plus uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
How do I reset my Samsung I9105 Galaxy S II Plus?
Use the Hard Reset method above if your Samsung I9105 Galaxy S II Plus 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 Samsung I9105 Galaxy S II Plus?
"Formatting" and "factory resetting" mean the same thing for the Samsung I9105 Galaxy S II Plus — both erase all data and restore default settings. Use whichever method above matches your situation.
