Direct soldering to the motherboard (ISP) or removing chips requires advanced soldering skills. A small error can result in a "bricked" device that cannot be powered on or repaired.
Before proceeding, you must understand the implications of this process:
Check solder points; they are likely loose or have high impedance.

The Samsung KG lock is a security mechanism managed by Knox, which can lock devices if they are suspected of being stolen, not fully paid, or if they violate company policies (MDM). When activated, the device shows a "KG Locked" screen, rendering it unusable.
: Allows for direct communication with the storage chip. By connecting via ISP (In-System Programming) , technicians can flash specific KG-OFF debug files or modify the configuration without removing the chip. Flash File Updates (FFU)
Samsung Android devices utilize a specific partition table (PIT). The lock status is not stored in the standard system or data partitions, which are often wiped during a factory reset. Instead, the state is stored in a protected partition known as PERSIST or within the sds (Secure Data Storage) partition structure. Direct soldering to the motherboard (ISP) or removing
Enrolled in an Enterprise Mobile Device Management (MDM) system. Reported lost or stolen 1.2.5 .

After flashing, close the EasyJTAG software, desolder the wires, and reassemble the phone. Boot the device to confirm the KG lock screen is gone. Important Considerations Navigate to the or Partition Manager tab in the software
The KG lock is not fully removed. Re-read the RPMB or use a different patch.
Solder micro-jumpers carefully to the critical connection points: (Clock) CMD (Command) DATA 0
Erase the network locking states by formatting MODEMST1 , MODEMST2 , and VBMETA partitions.
Write a specially modified boot/firmware image that disables the KG check. 5. Verify and Reassemble
To ensure the KG lock does not accidentally trigger again via Google Play services or automatic updates, apply these setup steps on the first boot:
