Why reset your Umidigi Bison?
A hard reset on the Umidigi Bison fixes boot loops, forgotten PINs and persistent lag. The method above will 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 Umidigi Bison?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Umidigi Bison to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Umidigi Bison 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 Umidigi Bison?
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 Umidigi Bison?
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 reset my Umidigi Bison?
Use the Hard Reset method above if your Umidigi Bison 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 Umidigi Bison 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.
Does my Umidigi Bison have a hard reset button?
Not a single dedicated button — the Umidigi Bison uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
