AddROM Tool for Vivo Y21 FRP – Complete Google Lock Removal Guide

Getting locked out of your Vivo Y21 after a reset is frustrating, especially when that Google verification screen just won’t let you in. Whether you forgot your Google account, bought a used device, or someone reset your phone you’re now facing FRP (Factory Reset Protection). This is where the AddROM tool saves your time, sanity, and your phone.

What Is the AddROM Tool for Vivo Y21?

The AddROM tool is a small but powerful APK or ROM file that helps you bypass the FRP lock on Android phones. For Vivo Y21, it works by skipping the Google account screen and giving you back full access no password, no login, no guessing games.

There are two main types of tools:

• AddROM APK – Install directly on your phone without a computer.
• AddROM FRP ROM – Flashable file used with a PC, ideal if APK method fails.

Why Vivo Y21 Gets FRP Locked

This happens after a factory reset, and the phone detects a previously used Google account. It’s a security feature by Google good for preventing theft, but a pain when you’re the legit owner who forgot the login.

Common reasons:

• Phone was reset but not logged out of the Google account.
• You bought a second-hand device.
• You forgot your Google account login credentials.
• FRP kicked in after software update.
