Samsung Knox Guard Security: CRTL, Knox, KG, RMM, and OEM

Aug 26, 2024 / By Robert M. Taylor / in How To

Understanding Samsung Knox Security: CRTL, Knox, KG, RMM, and OEM Explained

Samsung has built a robust security framework known as Knox to protect its devices and users from potential threats. This layered security approach can sometimes lead to errors, especially when rooting or installing custom files. Common issues arise from terms like CRTL, KG, RMM, and OEM. Understanding these can help you resolve issues effectively. This article aims to demystify these terms, explain their meanings, and how to deal with related errors often encountered in Odin mode or what’s often referred to as download mode.

 

What is Samsung Knox?

Samsung Knox is a comprehensive security platform integrated into devices running Android 4.3 and above. It encompasses various features to safeguard sensitive information through sophisticated encryption and isolation of apps. Knox provides users with a secure environment for work and personal data, but it also poses challenges for users wanting to customize their devices.

Key Components of Samsung Knox Security

Let’s delve into the key terms associated with Samsung Knox:

1. OEM (Original Equipment Manufacturer)

Meaning: The term OEM refers to the original manufacturer of a device.

Functionality: Samsung employs OEM settings to prevent users from unlocking the bootloader and installing unofficial ROMs or rooting their phones. If the OEM option is “ON”, rooting and the installation of custom files are restricted. To enable unlocking, users must activate the OEM setting from their device's menu.

Issue: Usually, this option is hidden, making it inaccessible for the average user. Activating OEM can be crucial for those intending to customize their device further.

Solution: Activating this option typically requires entering the developer options on the device. Users may need to enable developer mode by going to “Settings > About Phone” and tapping on “Build Number” multiple times until developer options are unlocked.

 

2. RMM (Remote Monitoring and Management)

Meaning: RMM stands for Remote Monitoring and Management.

Functionality: This feature determines the ability to make system changes, including rooting and writing custom files. If RMM is marked as “Prenormal” or “Locked”, users won't be able to make these changes as it indicates that the device is secured and under monitor control.

Solution: To work around RMM restrictions, one must ensure the device condition is set to “Normal”. This might involve resetting the device, but keep in mind that unlocking such features without proper permissions may void warranties.

3. KG (KG State)

Meaning: The KG State is closely related to the RMM status.

Functionality: When the KG state is listed as “Prenormal”, it indicates that the device is locked against rooting and installation of custom software. If it is in a “Checking” state, the device is rendered as functional for modifications.

Solution: Users should look out for any documentation related to their specific device models that may describe how to transition the KG state from Prenormal to Checking, often involving specialized software tools or processes.

4. Knox

Meaning: Knox is Samsung’s proprietary security system.

Functionality: It segregates and protects user data within its secure spaces, primarily used in professional settings where data privacy and protection are paramount. When modifications are made to software via rooting or installing custom ROMs, users often encounter the dreaded “Warranty Void: 0x1” message. This signifies that the Knox warranty has been tripped, affecting the device's eligibility for official support and updates.

Solution: Once Knox is tripped, the warranty is permanently voided, and users may lose access to Samsung's secure services. It’s crucial to weigh the advantages of rooting against these drawbacks.

5. CRTL (Control)

Meaning: CRTL signifies Samsung’s new security measure primarily for MediaTek devices.

Functionality: The sec_crtl status denotes whether booting the phone in BROM test point mode is permissible. If it’s marked as (0), it's inactive, allowing for modifications.

A (1) status means it’s active, blocking such attempts.

 

Solution: Bypass techniques for this status should adhere to device-specific forums. It often requires deep knowledge of device firmware and flashing techniques.

The Impact of Samsung Knox on Rooting and Custom Firmware

When attempting to root a Samsung device or install custom firmware, the aforementioned terms play pivotal roles. Users frequently face obstacles rooted in Knox’s security protocols. Notably, encountering any of these statuses in Odin Mode signifies restrictions currently in place.

Proven Ways to Remove Knox Lock and Unlock Android Devices for 2024: A Comprehensive Guide

Owning a smartphone is nearly a necessity. For many, Samsung devices provide reliable performance, a rich suite of features, and robust security measures. However, one significant hurdle that some users encounter is Samsung Knox—an advanced security platform that protects sensitive data by locking certain device functionalities. For individuals who wish to customize their devices, or those using phones on loan from companies like M-KOPA, PayJoy, or Watu Credit, navigating Knox can be particularly challenging. In this article, we will dive into proven methods to remove Knox Lock and bypass its security features, especially for Android versions 12, 13, and 14.

Understanding Samsung Knox

Samsung Knox is a comprehensive security solution designed to protect personal data and enterprise information while providing users with a secure workspace environment. While it ensures data integrity, it can also limit user customization, making it hard to use devices for multiple purposes. This is particularly true for devices marked with a "KG Locked" status, often used by businesses to protect sensitive information.

Why Unlock Knox?

  1. Personal Use: If you purchased a device on loan, unlocking Knox can enable unrestricted personal use without financial penalties.
  2. Customization: Users often want to personalize their devices with custom ROMs or apps that require root access.
  3. Device Performance: Removing Knox can lead to better performance and more dynamic use of the device's capabilities.

Understanding OEM Unlocking and Status Completed 11 on Samsung Devices

What Does Completed 11 or 00 Mean?

 

When you complete the OEM unlocking process, represented by Completed (00) or (11), you are essentially:

 

After Completed 11 this allows you to modify your device's firmware on a Knox locked device.

Flashing Knox Off Firmware: This means you can install custom firmware that disables the Knox security system.

 

Without achieving these completed 11 or 00, you won't be able to flash Knox-off firmware, limiting your device's customization options.

 

Bypassing the Knox Lock

 

The state of your Knox lock can significantly affect your device's usability:

Active State (01): You can bypass the Knox lock but it won’t be permanent. This means:

You can use the phone temporarily without restrictions.

However, if you perform a hard reset, the KG lock will reappear, reinstating the Knox security.

Permanent Bypass: Achieving a permanent bypass means:

 

You can use the device without encountering the Knox lock after a reset.

This is ideal for users who want a fully functional device without the worry of Knox restrictions returning.

 

Conclusion

 

Understanding these processes and terminologies is vital for anyone looking to modify their kg locked Samsung devices. Whether you're aiming for a temporary workaround or a permanent solution, being informed can help you make the best choice for your needs. Always proceed with caution, as modifying your device can void warranties and lead to potential issues if not done correctly.
