This post is an attempt to try and catalog some of the more useful values that can be changed (and the result of changing them.) Not all the variables seem to do much, and only by trial and error can we really know what will happen... So far, I've only played around with items I found interesting, but will continue to expand in this and if people reply to this post with actual experience changing other variables, I'll add the information to this thread.
PLEASE TEST THINGS AND CONTRIBUTE TO THIS THREAD.
Please don't reply with guesses as to what things may or may not do or with requests about specific variables. I'm hoping that eventually document every CSC variable available and "requests" won't make it go faster. If you want to know what a not-yet-documented variable does, try it out (and post your results.)
First, in order to play with the csc files, your phone should be rooted. This isn't optional, as you'll need the ability to overwrite files in the phone's /system partition (the firmware - sometimes improperly called the "ROM")
I'd strongly suggest making a nandroid (or backup via CWM Recovery or TWRP) before making changes. It's possible to mess things up badly enough that the phone won't boot properly.
It's possible to edit the CSC files directly on the phone, but I'd strongly suggest not doing that. Therefore, you should have a good text editor on your computer that's able to properly deal with unix/linux style line endings (notepad isn't good enough.) Notepad++ is a very good editor and freely available. Google "notepad++" For a linux box, plain "gedit" is fine.
In order to edit the files, you'll need to be able to mount the /system partition as read-write, and to move files from /system/csc to your PC or other location for editing. You have several options for this including root explorer, ES File Explorer, or just using adb. I prefer adb myself, but I'm a commandline type of person.
I won't be spending time describing how to get the CSC files off your phone to your PC, nor will I tell you how to overwrite the existing ones with your edits. This isn't because I'm elitist, an a**hole, or anything like that. (I _am_ some of those things, but that isn't my reason here.) My purpose for leaving out the information is to force inexperienced users to learn these things before editing system files. If I give you all the information, you become dependent on me for more information, and I don't want that (and trust me - neither do you.) As well, if I spoon-feed this, you won't have any idea what do to when something goes wrong.
Find this post helpful? If so, please make it MORE helpful by testing one of the other CSC features and replying to this thread telling us what result you had.
