Along with the Android Lollipop 5.1 Operating System, Google has introduced a new security feature designed to render the phone unavailable for usage in the unfortunate event when it might get stolen or lost.
Here’s how the Google Account Verification works
Let’s say that you just lost your phone and another person found it. Normally, this person will not be able to use the phone if you have already set up a screen lock pattern or security PIN.

In the past, this could have been easily bypassed by just factory resettingthe device.
Now, since Google introduced the new Google Account Verification or Factory Reset Protection (FRP) the phone becomes unavailable for use if the person performing the factory reset does not have the credentials of the Google Account that was previously logged on the phone.
This can also heavily impact users that buy the device from a third party and cannot get in touch with the person that sold them the phone. Most users reported not being able to use the phone because they could not get past the screen where the phone asks for the Google Account.
Solution- 1st Method
After the phone has finished its factory reset it will reboot and you will be prompted to choose the desired display language. After choosing the correct language please follow the next steps:
Connect the phone to a Wifi Network (preferably your Home network)
The next screen will ask you for the Google Account
Tap the text field in which the account should be inserted until the Keyboard comes up
Tap and hold the “@” character until a Settings menu pops up
Select Google Keyboard Settings
Tap on the 3 dots in the top part of the screen (or Moredepending on what Android OS you are running)
Select the Help&Feedbackitem and select any item in the list that will follow
Long press to select anytext on this page and click on Websearch in the upper right corner
A search field will be shown (delete the text inside the search field)
Type Settings in the search field
Tap “About Phone” and tap 7 times on the Build Number to enable Developer Options
Return to the previous menu and open the Developer Option that just appeared
Allow OEM Unlocking and tap Back two times
Restart the device
Connect it to Wifi again
Notice how you won’t be prompted to log in the previous Google Account and instead the phone will ask you to ADD a new Google Account
Excellent work darling
