Frequently asked questions
Will a hard reset delete everything on my Samsung Galaxy S II T989?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Samsung Galaxy S II T989 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Samsung Galaxy S II T989 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 Galaxy S II T989?
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 Galaxy S II T989?
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 Samsung Galaxy S II T989?
"Formatting" and "factory resetting" mean the same thing for the Samsung Galaxy S II T989 — both erase all data and restore default settings. Use whichever method above matches your situation.
How do I reset my Samsung Galaxy S II T989?
Use the Hard Reset method above if your Samsung Galaxy S II T989 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.
Can I factory reset my Samsung Galaxy S II T989 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.
