Overview[edit]
Factory Reset Protection (FRP) is a built-in security feature used in Android smartphones. This feature blocks any person from accessing the phone past the login screen after a factory reset, unless the Google login and password credentials for the account linked to the device are known.[1]
Security Features[edit]
Android smartphones with Lollipop 5.1 and higher were given a security feature called data protection, often known as Factory Reset Protection (FRP) by Google in March 2015. [1] When you set up a Google Account on a smartphone, FRP is instantly active. [1] If a factory reset is forcefully executed on the device without authorization, it disables other individuals from using it. Factory resetting an Android phone means restoring it to the factory settings and removing all data from it. It is also known as "formatting" or "hard reset". [2] When the device is reset via recovery mode, an untrusted reset, a hard key reset, an Android Device Manager (ADM) reset, or repair services, FRP lock activates. To set up the device after a factory reset, the unauthorized user will be required to enter the login information for the most recently synced Google account. In these instances, after the device has been reset, you will need to enter the Google ID and password connected to it. The device will give you the following message once you reach the google account sign in page:
“This device was reset. To continue, sign in with a Google Account that was previously synced on this device.” [2]
FRP is automatically disabled when you make a hard reset directly from the backup and reset settings because the synced Google account login information must be entered before the actual device will reset.[3]
Bypassing FRP[edit]
There can be multiple reasons an individual may want to bypass the FRP on an Android phone (device was reset and login credentials were forgotten, a thief or hacker trying to reset the phone for themselves, or a user wanting to add a custom firmware to phone). There are also many ways individuals have used in the past to bypass FRP. But in recent years, it has proven challenging to maneuver around the security feature. In order to prevent bypassing of FRP, Google will release updates and add new protocols to Android firmware. Before phones were updated with Lollipop 5.1 and higher, it was much easier to work around the security. [3]
A devices bootloader can be locked or unlocked. Unlocking the bootloader allows a custom recovery system or kernel or a modified version of Android to be installed. [4] Unlocking is a popular method to gain root access to a device, it is sometimes called "rooting" or "flashing" the phone. Some manufacturers disable the unlock functionality. The majority of the manufacturers of mobile phones have included FRP or a similar feature in their own models.
Most popular ways attempted at bypassing:[5]
- Bypass with PC
- Purchase software tool designed for FRP bypassing
- Recover Google account on a different device
- Bypass on FRP locked phone through series of steps specific to the device
- FRP Bypass APK tool
- Using On The Go cable (OTG)
Disabling FRP[edit]
There is an option to manually disable FRP on an Android device. Disable any security features currently implemented on the phone (lock screen security, remove all accounts and passwords, remove OEM protection). [5][3]
