Remove JTAG connections. Reassemble the phone minimally (battery, power button). Boot to (Volume Down + Volume Up + USB cable). Use Odin v3.14.4 to flash the same binary version (U or U1) that was previously on the phone. Do NOT flash a lower version – it will re-trigger KG Prenormal.
The Samsung KG lock, also known as the "KG Lock" or "Knox Guard Lock," is a security feature introduced by Samsung to protect its devices from unauthorized access. While it's designed to prevent device misuse, it can sometimes become a hurdle for users who need to access their devices for legitimate reasons. Easy JTAG Exclusive is a popular tool used for various mobile device repairs, including KG lock removal.
Solder or press the JTAG connector pins carefully. Connect the box to your PC via USB. Open . Select your target CPU (e.g., Exynos 2100 or Snapdragon 888 – KG lock logic exists at the TrustZone level on both). samsung kg lock remove easy jtag exclusive

(KNOX Guard / KG) is Samsung’s bootloader lock that prevents unauthorized flashing and can permanently brick or restrict devices if improperly handled. It often activates on devices with tampered partitions or failed firmware flashing. JTAG-based methods can sometimes recover or remove KG-related issues when software-only tools fail.

If you need further hardware troubleshooting, I can provide the or recommend specific partition patch files if you share your device's exact model number (e.g., SM-A042F or SM-A536B) and its current binary version . Share public link Boot to (Volume Down + Volume Up + USB cable)
Samsung is actively fighting hardware methods. In One UI 6.1 (Android 14), they introduced – a flag stored in the e-fuse inside the CPU, not the eMMC. For these devices (e.g., S24 with Snapdragon 8 Gen 3), even JTAG cannot reset KG.
Open Easy JTAG software. Select your Samsung chip (e.g., Samsung KLUEG8UHDB). Read the following full partitions:
Samsung devices are lauded for their top-tier security features, with being one of the most robust.
