Alright, I'm running CyanogenMod 11 with TWRP as my recovery. When I try to change my build.prop it tells me that the action is not allowed because the system folder is mounted as Read only and not as R/W. I have tried using the chmod syntax 755 while in recovery but, after rebooting nothing has changed. Using my file manager (Solid Explorer) I have tried changing the permissions to be R/W by using the same chmod syntax. What have I done or am I doing wrong? I have never crossed this issue before with any other ROM or phone and I would like to add some additional speed and smoothness tweaks to the ROM build.prop. Have I tried another ROM to see if the same thing continues to happen? Nope, I sure haven't. If I did though and something magically changes to where it would begin working using another ROM, I still would not know how to fix the issue that I'm faced with now. Will ya please help? Thank you for your time in advance as well!
