Getting an error message like "Custom Binary Blocked by FRP Lock" when you've been tinkering with your Android phone's system, like its firmware can be frustrating. But don't worry, we've got your back! In this guide, you'll learn more about this error message and some useful methods to bypass it.

What is "Custom Binary Blocked by FRP Lock" Error?

FRP, or Factory Reset Protection, is a security feature introduced in Android 5.1 to safeguard your phone from unauthorized access or software changes. The FRP lock triggers on your device automatically when you perform a factory reset without logging out of your Google account.

If you attempt to root your device, modify critical settings, or install unauthorized software without first removing your Google account, FRP detects these actions and prevents the device from starting up. The "Custom Binary Blocked by FRP Lock" error message will pop up and prevent you from proceeding further.

To bypass this error on your Android phone, you'll need to revert your device to the stock firmware and then unlock the FRP lock using the methods below.

Custom Binary Blocked by FRP lock

Step 1. Revert to Stock Firmware

To bypass the "Custom Binary Blocked by FRP Lock" error, you'll need to first revert to the stock firmware on your device. For example, if your device is currently running Android 7.x Nougat but the stock firmware is Android 6.x Marshmallow, you'll need to flash back to Android 6.x Marshmallow.

In this situation, you can use Odin software to help you revert to the stock firmware. Odin is Samsung software that can assist you in flashing stock firmware, making modifications, updating, restoring your device, and unbricking Galaxy devices.

To use Odin to flash the firmware on your Samsung, you'll need:

  1. The latest Odin software tool for Samsung Android smartphones.
  2. The right stock Samsung firmware update for your device.
  3. A Windows PC.
  4. A compatible USB cable.

Here's how to flash the Samsung firmware update using Odin:

  1. Download and extract Odin to your computer.
  2. Download and install the compatible Samsung drivers for your device.
  3. Download the stock firmware from internet for your device.
  4. Boot your Samsung Galaxy into Download Mode by holding down the Power button to turn off your Samsung Galaxy device. Then, with the device turned off, press 'Power + Volume Down + Home' to enter Download Mode.
  5. Connect your phone to your PC using a USB cable.
  6. Add the firmware file to Odin and Begin flashing the firmware with Odin by click the 'Start' button.
  7. Wait for the process to finish.
  8. Check for the 'PASS' message on Odin and your device should reboot automatically with the new firmware.

Remember, be careful and follow the instructions closely to avoid any errors or problems during the process.
