Frequently asked questions
Will a hard reset delete everything on my NIU Andy 4E2I?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the NIU Andy 4E2I to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the NIU Andy 4E2I 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 NIU Andy 4E2I?
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 NIU Andy 4E2I?
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 NIU Andy 4E2I have a hard reset button?
Not a single dedicated button — the NIU Andy 4E2I uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
What is recovery mode on my NIU Andy 4E2I?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the NIU Andy 4E2I won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
Can I factory reset my NIU Andy 4E2I 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.
