Safety Measures ( which you shouldn't start without )

1. Have a working Ex-Link cable at hand.
2. Ensure the backup exe.img ( stored on /dev/tbml10 ) is in good condition ( and ideally not altered. )
3. Ensure your RS232 Setting in the Service-Menu is set to "debug".
4. Know that your TV will reset RS232 jack back to UART mode after new firmware installation or reverting back to old version.

Interesting Reference Material

• Introduction to SAMSUNG's Linux Flash File System - RFS

The file-system used in the the recent Samsung TVs is "RFS". Its proprietary nature and consequently so the absence of an according Linux RFS-Module in the standard Linux distributions makes it currently impossible to modify files by simply mounting the respective image as "RW", modifying it and saving the respective image again. This is the reason why currently all changes are done via patching of the image-binaries.

• Linux RFS ( Robust FAT File System ) Porting Guide

The information provided here should help, that we get a RFS module compiled for our common Linux distributions
