When you purchase a used Samsung phone from another person, the first thing you do is factory reset the device. And after you reset and restart the phone, you may see “An unauthorized attempt has been made to reset your device to factory default settings” message on the screen. The message appears because FRP lock is enabled and it prevents unauthorized factory reset and access to the phone. This is done to prevent wicked people from stealing phones and factory reset them to use in their daily lives. Since your intentions are not wrong, you should be wondering how to get past unauthorized factory reset. Here we will illustrate the most legitimate way to bypass unauthorized factory reset Samsung phone or tablet.

Part 1: What Does It Mean When It Says Unauthorized Factory Reset?

An unauthorized factory data reset refers to someone’s attempt to perform a factory reset on an Android phone without the owner’s authorization. To protect Android devices from unauthorized factory data resets and prevent use of a device, Google has introduced a security feature called factory reset protection (FRP) which requires users to authorize their identity by entering the credentials of the Google account that the device was logged into after a factory reset. If you factory reset your device but fail to authorize your identity, you will come across the message “An unauthorized attempt has been made to reset your device to factory default settings.” To get past this message, you have to enter the credentials of the synced Google account, otherwise, you will get stuck on the Google verification screen.
