Removing a Samsung Knox Guard (KG) lock using the Easy JTAG Plus box is a specialized hardware-level solution often used for devices where software bypasses are blocked. This "exclusive" method typically involves directly accessing the device's storage chip (eMMC or UFS) via ISP (In-System Programming) pins to modify the KG state or flash specific "KG-off" files. Core Methods for KG Removal
eMMC/UFS Modification: Technicians use the Easy JTAG Plus box to connect to the chip's data pins. This allows for a permanent KG lock removal by modifying the chip's internal parameters or flashing a debug/custom file that disables Knox security.
ISP Connection: For many models like the Samsung A33 5G or A53, an ISP pinout is used to connect the device to the box without removing the storage chip.
One-Click Solutions: Certain tool updates (like for the Samsung A245F) offer "one-click" MDM and KG removal features once the device is successfully connected to the Easy JTAG interface. Common Steps in the Process

What Is Samsung KG Lock? (And Why Normal Methods Fail)
KG Lock is part of Samsung’s KG Status mechanism, introduced with Android 11 (One UI 3.0) and fully enforced in later versions. It interacts directly with the RPMB (Replay Protected Memory Block) partition and the e-fuse bits on the device’s UFS (Universal Flash Storage) chip.
When a device is KG locked, it means:
- The device was previously linked to a Samsung account with OEM unlock disabled.
- A factory reset was performed without removing the account, triggering the RMM (Remote Mobile Management) KG Prenormal state.
- The device refuses to boot past the setup wizard or enter download mode without a time-based server check (usually 7 days).
Normal methods like:
- Volume Down + Power hard reset
- Odin flashing (fails on “Pre-Validation”)
- ADB commands (disabled in prenormal state)
- Combination firmware (often triggers a hard KG failure)
…all result in the same red text: “KG State: Prenormal / Locked.”
5. Finalizing
- Once the write process is 100% complete, disconnect the EasyJtag box.
- Unsolder the jumper wires.
- Reconnect the battery.
- Power on the device.
