Samsung KG Lock Removal: A Step-by-Step Guide Using Easy-Jtag Plus
Dealing with a Samsung KG Lock (Knox Guard) can be incredibly frustrating. Whether it’s a device locked due to missed finance payments or an accidental enterprise lock, it effectively turns a high-end smartphone into a paperweight.
While software-only bypasses exist, they are often temporary. For a permanent solution, professionals turn to hardware-level intervention using the Z3X Easy-Jtag Plus Box Go to product viewer dialog for this item.
. In this post, we’ll break down how to use this powerful tool to remove the KG lock via ISP (In-System Programming). What is Samsung KG Lock?
The KG Lock is part of Samsung’s Knox security framework. It is a cloud-based lock that ties the device’s IMEI to a server. If the server flags the device (e.g., for "Finance Lock"), the phone blocks access to the UI. Because this lock resides deep in the device’s RPMB (Replay Protected Memory Block) and specific EMMC/UFS partitions, standard factory resets won’t touch it. Essential Prerequisites
Before starting, ensure you have the following hardware and software ready: Z3X Easy-Jtag Plus Box : The main hardware interface.
Easy-Jtag Plus Software: Ensure you are running the latest version of the "Classic" or "Plus" suite.
ISP Adapter & High-Quality Jumper Wire: To connect the box directly to the motherboard’s EMMC/UFS pins.
Device Pinouts: You must find the specific CLK, CMD, D0, VCC, and VCCQ pinouts for your specific Samsung model.
Soldering Skills: This process requires precision soldering on a microscopic level. Step-by-Step Guide to Removing KG Lock 1. Hardware Connection (The ISP Method)
Open your Samsung device and locate the ISP pinouts on the motherboard. Carefully solder your jumper wires from the Easy-Jtag Plus ISP Adapter Go to product viewer dialog for this item. to the corresponding points on the board.
Tip: Keep the wires as short as possible (under 10cm) to ensure a stable data connection. 2. Identify the Chip Connect the Easy-Jtag Plus Box to your PC and launch the EasyJtag Plus software. Set the interface to eMMC or UFS (depending on your phone). Set the voltage (usually 1.8V or 2.8V).
Click "Check eMMC/Connect". If successful, you will see the device's partition table and health report. 3. Backing Up Critical Data
Never skip this step. Before modifying anything, go to the "Read" tab and backup the following partitions: ROM1 (User Data) EFS (Contains your IMEI and network data) BOOT1 and BOOT2 4. The KG Lock Removal Process
There are two primary ways to handle the KG state using Easy-Jtag: A. Modifying the Partition (The "State" Change) Go to the "Browser" or "Partition Table" tab.
Locate the partition responsible for the lock (often labeled as persistent, steady, or model-specific partitions).
Right-click and select "Erase". This clears the local flag that tells the phone it is locked.
B. Using the Samsung Tool TabThe Easy-Jtag suite often includes a dedicated "Samsung" tool. Navigate to the Advanced or Samsung tab. Look for the "Remove KG Lock" or "Fix KG State" button. Look at your pinout diagram
The software will automatically patch the necessary blocks to change the KG state from Active/Locked to Checking or Broken. 5. Finalizing and Flashing
Once the KG state is cleared, disconnect the ISP wires. You will likely need to flash a clean, official firmware using Samsung Odin.
Important: During the initial setup, do not connect to Wi-Fi immediately. Complete the setup offline to prevent the device from re-syncing with the Knox servers until you have disabled the necessary system apps (like com.samsung.android.kgclient) via ADB. Risks and Warnings
Warranty: Hardware-level modification voids your warranty immediately.
Brick Risk: Incorrect soldering or erasing the wrong partition (like the RPMB incorrectly) can lead to a hard brick.
