What is KG Lock?
KG Lock (Knox Guard Lock) is Samsung’s advanced security protocol designed to protect devices from unauthorized access and tampering. When triggered, it completely locks the device and displays messages like:
- “Custom binary blocked by KG Lock”
- “Unauthorized software detected”
- “This phone has been reset with unauthorized software”
Unlike FRP (Factory Reset Protection) which is Google’s software-level protection, KG Lock operates at the hardware level through Samsung’s Knox security platform, making it more challenging to bypass without professional tools.
Why KG Lock Happens
Understanding the triggers can help prevent future lockouts:
- Factory Reset Without Proper Preparation – Performing reset without first removing Google account and Samsung account
- Unauthorized Firmware Flashing – Attempting to install custom ROMs or modified firmware
- Failed Software Updates – Interrupted OTA updates or corrupted firmware installations
- Security Policy Violations – Attempting to root or modify system partitions
- Corporate Device Management – Company MDM (Mobile Device Management) policies triggering remote lock
- Warranty Void Triggers – Knox warranty void counter reaching threshold (0x1)

A: This indicates the bootloader is still locked. Simply repeat the process ensuring you:
- Enable OEM Unlocking in Developer Options first

Understanding FRP Lock
FRP (Factory Reset Protection) is Google’s account verification system that activates after a factory reset. While related to KG Lock, there are key differences:
| Feature | KG Lock | FRP Lock |
|---|---|---|
| Implemented By | Samsung Knox | |
| Trigger Level | Hardware/BIOS | Operating System |
| Bypass Difficulty | High (requires special tools) | Medium (several methods available) |
| Common Triggers | Unauthorized firmware | Factory reset without Google removal |
TSM Tool Pro can bypass both KG Lock and FRP Lock simultaneously in most cases, saving time compared to handling each separately.

- Initial KG Bypass – Complete standard KG Lock removal first
