FRP lock, also known as Factory Reset Protection lock, is a new security feature for devices running Android operating system 5.1 and higher. This new feature is designed to prevent unauthorized factory reset or software modification of a device without a user’s permission. This feature uses the registered Google account on the device as the verification measure to check if the software modification being done is authorized or not. That your device shows the “Custom Binary block by FRP lock” error means that there is a Google account logged in. FRP feature is only enabled if a Google account is present on the device. It also means that the phone you are working on have screen lock feature enabled. Your device should have prompted you to enter the correct lock screen as well as your Google account credentials to perform a factory reset or software modification in the first place. Did you do this? If the phone didn’t prompt you to enter your Google account credentials, try to call Samsung and ask them for more direct assistance regarding this new FRP lock feature. Or your can visit
Samsung’s site to know more about it.
Because it’s a new security feature, there is no known hack to bypass it at this time. If reflashing via Odin does not work for you, we don’t know any other means to resolve the issue you have except to tell you to ask Samsung for help. We know that you have already attempted to do that but try to call them again and simply tell them that you lost access to your Google account. Perhaps they can be persuaded to assist you if you can present proof that you are the rightful owner of the device
