NANDroid Backup Question!! Please answer, it is very important and vital!

Let me start by saying that I want to modify my Mixer_Paths.xml file located at /System/etc so I can increase the headset Volume of my LG G Stylo. I want to know, as long as I have a Nandroid backup on TWRP with System and Data selected, can I modify the file and if it corrupts and I have no sound, can I restore the device back to the way it was before I modified the Mixer_paths file and everything work the way it worked before I modified it? Please answer, as this is vital to me because I want to make my headphone volume be loud enough to have it at lower than 50% volume and it be loud like an iphone. Don't ask me why, I just do. Thanks in advance

Yes. As long as you have a backup before making the changes than you have no worries
