Tested KG Bypass Firmware for Samsung Galaxy A13 5G (SM-A136B)
This is a specialized, tested firmware designed specifically for the Samsung Galaxy A13 5G (Model: SM-A136B) with Binary U2. Designated as A136BXXS2AVI1, this file effectively acts as a KG (Knox Guard) Bypass and Knox Remove solution.
This firmware is indispensable for repair technicians facing devices stuck on the KG Locked screen or those undergoing frequent restarts due to MDM (Mobile Device Management) activation. It is crucial for restoring full functionality and preparing the device for subsequent standard flashing procedures or unlocking services.
Key Features and Functions:
- KG Bypass/Remove: Permanently removes the Knox Guard/MDM lock, eliminating the "KG Locked" state.
- Knox Removal: Neutralizes the device's Knox security features that often interfere with repair processes.
- OEM Off & FRP Off State: Once flashed, this firmware sets the device parameters to OEM Unlocked and FRP (Factory Reset Protection) Off, allowing further modifications and flashing without security blocks.
- Enables Flashing/Downgrade: Facilitates the use of standard flashing tools (like Odin) without triggering critical security warnings.
Important Requirements and Usage Notes:
- Binary Compatibility: This file is strictly for devices running Binary/Bootloader Version U2. Flashing on an incompatible binary version will result in a hard brick. Always check the device's current bootloader version before proceeding.
- Flash Tool: Requires Odin Tool (v3.14 or newer) to flash.
- Prerequisites: The device must be able to enter Download Mode.
