Click “Run Script on Target”. The process takes 30–90 seconds. Successful output looks like:
Searching for KG block... Found at 0x4E000
Backing up original KG data... Done.
Patching KG state... Prenormal → Normal
Writing UFS page 0x4F4C... OK
Verifying write... Match.
KG Lock removed successfully.
Go to the “UFS” tab. Click “Read Full Dump” (size varies by model, 64GB–256GB – allocate storage space). Save the raw dump as backup_full.bin. This is your lifeline in case of error.
KG stands for Knox Guard. Introduced with Android 11 (One UI 3.0) and hardened in later versions, KG Lock is Samsung’s enterprise-grade anti-theft and device protection mechanism.
There are two common states:
For repair shops and advanced hobbyists, the Easy JTAG exclusive KG removal method is currently the only reliable way to unlock a Samsung device stuck in KG Prenormal state with a newer bootloader. It bypasses the time lock, ignores Samsung’s server validation, and works at the hardware level.
That said, it demands patience, soldering skills, and access to paid scripts that are not publicly distributed. But if you’re staring at a thousand-dollar paperweight with “KG State: Prenormal” and no way out, this exclusive JTAG method is the proven, permanent fix.
Final tip: Always check your device’s bootloader version (getprop ro.boot.bootloader) before starting. If it’s rev 5 or higher on Exynos 2200, you may need an even newer exclusive script version. Keep your Easy JTAG software updated, and never skip the full UFS backup.

The "Samsung KG Lock Remove" feature in Easy-JTAG Plus a specialized tool used by technicians to bypass or permanently remove Knox Guard (KG) restrictions on Samsung devices
. This lock is typically used for financing (e.g., PayJoy) or enterprise management and can prevent a phone from being used if payments are missed or if it is managed by a company. Core Capabilities
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. Click “Run Script on Target”
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)
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. Go to the “UFS” tab
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)
This is an advanced repair procedure used when a Samsung device is "Prenormal" (stuck on a setup screen asking for the previous owner's Google account) or locked by Samsung's Remote Mobile Manager (RMM), preventing OEM Unlocking.
Here is a feature breakdown and guide on the EasyJTAG Exclusive method for removing Samsung KG Lock via eMMC/ISP.
Follow these steps exactly. A single wrong memory write can hard-brick the device beyond recovery.
