Why reset your BLU Vivo IV?
A hard reset on the BLU Vivo IV 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 BLU Vivo IV?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the BLU Vivo IV to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the BLU Vivo IV 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 BLU Vivo IV?
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 BLU Vivo IV?
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.
Can I factory reset my BLU Vivo IV 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.
What is recovery mode on my BLU Vivo IV?
Recovery mode is a stripped-down menu outside the normal operating system, used to wipe data or apply updates when the BLU Vivo IV won't boot normally. See the Enter Recovery Mode section above for how to reach it on this device.
How do I reset my BLU Vivo IV?
Use the Hard Reset method above if your BLU Vivo IV 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.
