Notes:

This Kernel was changed to work with old Modem EFS_V1 on new Samsung based Jelly Bean 4.3.x roms!!!
This Kernel is only for the new Samsung based Jelly Bean 4.3.x roms!!!

Big thanks to Lord Boeffla the creator of this awesome kernel, all i have done was litle changes that the kernel cold work with old modem EFS_V1

Disclaimer

*** As always - Flash on our own risk! ***

Make sure you flash the correct version depending on your firmware version!

I can and will not take any responsibility for bricked phones or lost data.

It is generally recommended to run a complete Nandroid backup in CWM recovery and safely store your personal data before you flash a new kernel.


Cheers and enjoy

If you are on old modem yes but on new ones I haven't tested because I'm stuck on old modem efs v1.
If you have efs v2 you can flash the official one of Lord Boeffla.

What is the difference between the SE for Android status: Enforcing, Permissive and Disabled?

Enforcing — SE for Android is enforcing the loaded policy. Your device is actively protected from security threats and malicious apps will be denied access.

Permissive — The SE for Android policy file is loaded, but your device is not enforcing it. If a malicious app tries to access a resource that it is not allowed to, the access will be logged but not prevented. This mode is intended for testing and debugging. It generates log files of denied app and allows Samsung to identify new app threats and update its policy files.

Disabled — The SE for Android infrastructure is not enabled, and there is no policy file loaded. Log files are not generated and your system is vulnerable to security threats.

To find out how to check a device’s SE for Android status (formerly called SELinux status), see the KNOX User Guide on the KNOX web portal > Resources tab. You cannot change this setting.

After you flash the ROM flash old modem and this kernel. Only if you are stuck on efs_v1
