Phone boot loop, Custom binary blocked by FRP lock.
phone blocked screen says custom binary blocked by fap lock
So, when you get the message 'Custom binary blocked by FRP lock' it means you have flashed a unauthorized binary file to the phone and the phone is preventing itself to boot since it has detected the modified file(s).
Now to fix this to at least boot up properly you need to reflash the Samsung Firmware for your phone.
Match it to the model number shown on the back cover of the phone (SM-G9xx for example) or model number shown in download mode which you can access if you keep holding power + volume down + home until you get to light blue screen.
Here is a guide on how to flash Samsung Firmware:
Note if you want to also remove Google Account Lock you will need to use the method shown here:
Note that in most cases you will need to downgrade the firmware on the phone back to Android 6.x Marshmallow if you are already on Android 7.x Nougat for the FRP bypass method to work.
1. You'll need to enable the hidden "Developer options" menu by heading to About phone (or About tablet) in Settings, then tapping the "Build number" entry 7 times in rapid succession.
2. Head to the "Developer options" menu, then toggle the switch next to the "OEM unlocking" entry to enable it.
Whenever you get the "Custom Binaries Blocked by FRP Lock" in red letters at the top of the screen when you try to boot to recovery, Ben who previously answered is partially correct in saying you have flashed a(n invalid) file to the phone and the phone is preventing itself to boot since it has detected the modified file(s). This can happen when you are trying to establish Root or flash a ROM that is incorrect for your device. Typically sometimes flashing in the official firmware may help, yet sometimes it does not. When that happens what's needed is an "Unlock FRP" file that most often is specific to each device. This means you can't just use any unlock frp file and this is not the kind of FRP lock that has to do with Google Sign in stopping you from accessing the device functionality. In Binary Lock Mode the device does not load past the Logo screen. BE ADVISED! This will also fatory reset your device.
Open and fastboot minimal and type adb devices then if it says connected to android with a serial number then you are connected to and then type dab boot loader reboot boot loader then type dab boot loader oem unlock oem and that should be it then boot up phone and go to settings and go to about device then look for build number tap it repetitively till it says developer options are open then back out and go to settings at the bottom you will see developer options and in there check oem on and fixed

To see you trying help each and every one of these folks is a breath of fresh air.

Hi, my Samsung Galaxy S7 fell into Custom Binary FRP Lock after plugging it in to charge. I tried to access the download mode to update the framework as per the instruction/advice found on this site. My phone does not go into download mode after pushing the relevant keys. The only screen that shows is the Samsung logo page with a red message stating Custom Binary FRP Lock and a green LED light that is constantly lit. Is there another way to access the download mode? Is there a way to fix the FRP Lock another way?
Usually that's due to a bad cord issue. Make sure you have the latest Samsung driver installed on your PC. Even in the worst of conditions Odin3 will detect the device regardless of which version of Odin3 your using. For the J7 I would suggest Odin3.13.3. You must first return to device back to official status. You may need what's called a combination or repair file. Go to https://samsungfirmware.net/category/sam... and enter your devices model number, then scroll down to find the (binary) firmware. Install via Odin3. Good luck.
This custom binary block error can be solved by flashing the device with official firmware through Samsung Odin.
Simply download your device firmware. make sure the firmware is the latest one. you can download the firmware from androidfilehost, sammobile or any other firmware directory. anyone can flash it easily by Odin. But make sure you know the google account of your device. Because if you don’t know it then your device will be frp google account verification locked. To unlock FRP Lock or reactivation lock from any Samsung device check this Samsung FRP Bypass Guide.
