How to Remove Samsung KG Lock Using Easy J-Tag Plus (Exclusive Method)
The Samsung KG Lock (Knox Guard) is one of the most sophisticated security features in modern Samsung devices. Often triggered by unpaid financing or lease agreements, it restricts access to the phone's features or locks it entirely. While many software-based bypasses are temporary, using the Easy J-Tag Plus box offers a more permanent, hardware-level solution by interacting directly with the device's UFS or eMMC storage.
This guide explores the exclusive method for removing the KG lock using this professional forensics and repair tool. Understanding the KG Lock
Before proceeding, it is vital to understand that KG Lock is not a simple FRP (Factory Reset Protection) lock. It is integrated into the RPMB (Replay Protected Memory Block) and the TrustZone of the processor. A standard factory reset or firmware flash will rarely solve the problem, as the device will re-lock as soon as it connects to the internet. Prerequisites To perform this operation, you will need: Easy J-Tag Plus Box with the latest software installed.
High-quality ISP (In-System Programming) adapters or a UFS/eMMC socket. The specific ISP Pinout for your Samsung model. A stable power supply (usually via USB or the box itself).
Working knowledge of soldering (if using ISP) and partition management. The Exclusive Removal Process 1. Hardware Connection
The first step is establishing a connection between the phone's motherboard and the Easy J-Tag Plus box. You can do this by:
ISP Method: Soldering tiny wires to the CLK, CMD, and DATA0 points on the motherboard.
Chip-off Method: Desoldering the UFS/eMMC chip and placing it in a dedicated socket (the safest but most difficult method). 2. Detection and Backup Once connected, open the EasyJtag Tool suite. Select the correct interface (eMMC or UFS). Click "Check Device" or "Identify".
Crucial: Before making any changes, create a full backup of the ROM1 (User Data), ROM2/3 (Boot partitions), and specifically the EFS and SEC_EFS partitions. This ensures you can recover the device if the process fails. 3. Modifying the Partition Table
The "exclusive" part of this method involves targeting the configuration files that store the KG status. Navigate to the Browser or Partition Manager tab.
Look for the persistent or config partitions. In some newer UFS models, the KG status is checked against the RPMB data.
Professional technicians often use the "Advanced" tab to wipe the specific flag sectors. 4. The "Zero-Fill" Technique
For many Samsung models, clearing the RPMB (if the chip allows) or modifying the Param partition is necessary. samsung kg lock remove easy jtag exclusive
Wipe the param partition or flash a "cleaned" param file specific to your model.
Set the KG State to "Completed" or "Broken" in the boot configuration if the tool's script supports it. 5. Finalizing with Firmware After modifying the hardware partitions: Disconnect the hardware and reassemble the device. Put the device into Download Mode.
Flash a clean, official 4-file (BL, AP, CP, CSC) firmware using Odin or the Easy J-Tag Flasher.
Once the device boots, avoid connecting to Wi-Fi until you have disabled ADB and verified the KG status in the Developer Options. Important Safety Warning
Modifying hardware partitions is risky. If the RPMB is incorrectly handled, or if the EFS partition is corrupted, the device may lose its IMEI or become permanently bricked. This method should only be attempted by experienced technicians. Furthermore, always ensure you are complying with local laws regarding device ownership and software modification.
Samsung KG Lock Removal: The Exclusive Easy JTAG Plus Guide Removing the Samsung Knox Guard (KG) lock—often referred to as an MDM or finance lock—requires professional-grade hardware and deep technical knowledge. The Easy JTAG Plus Box is widely considered the gold standard for this task because it allows technicians to bypass software restrictions by interacting directly with the device's hardware through eMMC or UFS.
As of May 2026, here is the exclusive, technical process for permanently removing Samsung KG locks using Easy JTAG Plus. What is the Samsung KG Lock?
The Knox Guard (KG) lock is a cloud-based security feature used by carriers and financing companies to disable a device if payments are missed or terms are violated. Unlike standard FRP (Factory Reset Protection), KG locks are deeply integrated into the device's RPMB (Replay Protected Memory Block) or persistent partitions, making them nearly impossible to remove via standard USB flashing alone. Tools Required
Hardware: Z3X Easy JTAG Plus Box with updated eMMC/UFS sockets.
Interface: ISP (In-System Programming) pinouts or a direct BGA socket for the memory chip.
Software: EasyJtag Plus software suite and model-specific KG/MDM removal files (often called "dump" or "debug" files).
Technical Skill: Ability to perform micro-soldering for ISP connections. Exclusive Step-by-Step Removal Process 1. Device Preparation and Connection
You must first establish a hardware connection to the device's storage. For modern Samsung models like the A13 (A135F) or A04 (A042F), you typically use an ISP Pinout to connect the CLK, CMD, DATA0, and VCC/VCCQ points to the Easy JTAG Box. 2. Identity Modification (Serial Number & EFS) How to Remove Samsung KG Lock Using Easy
A critical step in "exclusive" methods involves changing the device's identity to prevent it from re-locking once connected to the internet. Read EFS: Back up the original EFS partition.
Serial Number Modification: Technicians often use the "Back to Normal EFS" feature in Easy JTAG to edit or clear the serial number from the KG term, preventing the Knox servers from identifying the device as "Locked". 3. Partition Manipulation
Using the EasyJtag Plus eMMC/UFS tool, navigate to the partition table:
Wipe Metadata: Some methods involve wiping the persistent and metadata partitions where KG status is stored.
Flash KG-Removed Dump: Flash a pre-modified dump file specific to your device's Binary (e.g., Bit 2, Bit 5, or Bit 8). These files are designed to set the KG status to "00" or "11" (Off/Broken) permanently. 4. Disabling Knox Services To ensure the lock does not return after an OTA update:
Use the Easy JTAG File Manager to access the system partition.
Manually disable or remove APKs related to Knox Guard, such as com.samsung.android.kgclient. Key Model-Specific Successes (2025-2026)
The process of removing a Samsung KG (Knox Guard) Lock using the Easy-JTAG Plus Box is considered a specialized, hardware-level solution for mobile technicians. This "exclusive" method typically involves deep-level modification of the device's storage (eMMC or UFS) to permanently disable the security protocols that enforce corporate or carrier locks. Understanding the Samsung KG Lock
The KG (Knox Guard) state is a security feature within Samsung's Knox platform. It is primarily used for:
Corporate Management: Allowing companies to remotely control and restrict employee devices.
Payment Protection: Locking devices if a customer defaults on a financing plan.
Theft Prevention: Rendering a device unusable if it is reported stolen or lost. The Role of Easy-JTAG Plus How to fix kg lock on Samsung
The "Exclusive" feature of using EasyJTAG for this task is the ability to bypass the Operating System entirely. While software tools like Odin require the device to be in a specific mode (which RMM Lock often blocks), EasyJTAG communicates directly with the eMMC chip on the motherboard.

Key Capabilities:
RMM_State file that flags the device as locked.persist.data or specific binary files to release the KeyGuard (KG) restriction.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:
Normal methods like:
…all result in the same red text: “KG State: Prenormal / Locked.”
If you are a mobile repair technician, a second-hand phone dealer, or an advanced user who has ever purchased a used Samsung Galaxy device, you have likely encountered the dreaded "KG Lock" (Knox Guard).
Imagine this: You perform a factory reset on a Samsung Galaxy S22, S23, or S24, hoping to clean it for a new user. Instead of booting normally, the phone stops at the Setup Wizard with a message: "This device is locked because the KG state is active. Please sign in with a previously synced Google account."
You try flashing stock firmware. You try the old "Google Account Bypass" tricks. Nothing works.
That is exactly where "Samsung KG Lock Remove Easy JTAG Exclusive" becomes the holy grail of modern Samsung unlocking. This article dives deep into what KG Lock is, why standard methods fail, and how the exclusive JTAG (Joint Test Action Group) method offers the only reliable backdoor.
Solution: Newer Samsung devices (2024+) use UFS 4.0 with encrypted ISP lines. You need the "Easy JTAG UFS Adapter" and must use EDL mode instead of direct ISP. Connect via USB and force EDL by shorting test points while running the exclusive loader.
Follow these steps exactly. A single wrong memory write can hard-brick the device beyond recovery.
