Why reset your Honor 400?
A hard reset on the Honor 400 fixes boot loops, forgotten PINs and persistent lag. Using Volume Up + Power, you can access recovery mode and wipe the device back to factory condition. Always back up your data first, as a reset cannot be undone.
Frequently asked questions
Will a hard reset delete everything on my Honor 400?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Honor 400 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Honor 400 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 Honor 400?
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 Honor 400?
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.
