What is KG Lock?
KG Lock (Knox Guard Lock) is Samsung’s advanced security protocol that protects devices from unauthorized modifications. 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”
KG Lock operates at the hardware level through Samsung’s Knox security platform, making it more challenging to bypass than standard FRP locks.
Why KG Lock Happens
- Unauthorized firmware flashing – Attempting to install custom ROMs or modified firmware
- Factory reset without proper preparation – Not removing Samsung/Google accounts first
- Failed software updates – Interrupted OTA updates or corrupted firmware
- Security policy violations – Attempting to root or modify system partitions
- Corporate device management – Company MDM policies triggering remote lock
- Warranty void triggers – Knox warranty void counter reaching threshold (0x1)
