My friend coded some of the options such as mirror folding, etc....in my car and I am trying to find the best way to back up all original. I saw he backed up FA, SVT and all .ncd. the E-Sys has been installed with all options on my PC and I can connect and get around the tool but I never done coding.
I really appreciated if some one tell me step by step how can i revert all coding back to original using the backup information. I need to take my car for warranty service to the dealer and I don't want them to blame coding for the issues.

Thx,
