This is the Factory Reset Protection (FRP). It is a security feature designed by Google to prevent thieves from using stolen phones. But what happens when you are the legitimate owner and you have forgotten your old password, bought a second-hand phone that wasn't properly wiped, or your child accidentally locked you out?

High (Works on build numbers ending in .51 and below) Difficulty: Medium

Imagine this: You’ve just performed a factory reset on your Sony Xperia L3 to clear up storage or fix a software glitch. You turn the phone back on, expecting a fresh start, but instead, you are greeted by a wall. A message reads: "This device was reset. To continue, sign in with a Google Account that was previously synced on this device."

The Xperia L3 uses the Google Setup Wizard (Google Setup Wizard), which relies on internet connectivity to verify credentials. The goal of any bypass is to interrupt this wizard, gain access to the settings menu or a browser, and disable the Google Account Manager. This is the most popular method for the Xperia L3 because it requires no computer, no cables, and no software. It exploits a loophole in the Android Accessibility suite.
