Samsung KG/MDM/Knox Lock Remove Tool (Free 2025 Edition) – SRS MDM Tool
Overview
Samsung devices are equipped with strong security layers like KG (Knox Guard), MDM (Mobile Device Management), and Knox Security, designed to protect data and prevent unauthorized access.
However, these same protections can sometimes restrict users from accessing essential functions — especially after repairs or ownership transfers.
The SRS MDM Tool (2025 Free Version) offers a safe, permanent, and efficient way to remove these restrictions from Samsung smartphones without any data loss.
Understanding KG / MDM / Knox Lock
Before using the tool, it’s important to know what these terms mean:
-
KG Lock (Knox Guard Lock):
A factory-level protection that prevents flashing or unlocking unauthorized firmware. Often activated remotely by Samsung servers. -
MDM Lock (Mobile Device Management):
Typically used by schools, companies, or organizations to control and limit access to devices. It prevents modification or factory resets without admin permission. -
Knox Security:
Samsung’s advanced hardware and software security layer protecting system integrity, encryption, and firmware verification.
Once active, it disables several phone functions such as OEM Unlock, Developer Options, and Factory Reset.
