Why reset your NIU Niutek 4.5D?

Frequently asked questions
Will a hard reset delete everything on my NIU Niutek 4.5D?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the NIU Niutek 4.5D to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the NIU Niutek 4.5D 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 Niutek 4.5D?
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 Niutek 4.5D?
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.
What is recovery mode on my NIU Niutek 4.5D?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the NIU Niutek 4.5D 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 Niutek 4.5D 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 format my NIU Niutek 4.5D?
"Formatting" and "factory resetting" mean the same thing for the NIU Niutek 4.5D — both erase all data and restore default settings. Use whichever method above matches your situation.
