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