What should I do when my device shows ‘custom binary blocked by FRP lock’?
Recently, I encountered a frustrating issue with my Samsung device where the screen displayed a message saying ‘custom binary blocked by FRP lock.’ I understand that FRP (Factory Reset Protection) is a security feature designed to prevent unauthorized access to my device, especially after a factory reset. However, I’m puzzled by the ‘custom binary blocked’ part. Whenever I try to boot up my device, it fails to start normally and gets stuck on this error message. I haven’t tampered with the firmware or installed any custom binaries intentionally, so I’m unsure why this happened. This situation is quite inconvenient as I rely heavily on my phone for daily tasks and communications. I’m looking for a comprehensive understanding of why my phone is displaying this message and what underlying issues might be causing it. Specific guidance on precautions I should take to prevent this from happening again would also be helpful.
