Use Triangle away.
THEN make all your modifications to the phone. Triangle Away won't be the cause of the brick if you do it in that order. Triangle away causes problems when you try to use it when you aren't on the stock rom or recovery. So use it before you change the rom or recovery.
do those backup my entire system ? if i fk up and have a back up how do i flash it?
EDIT : CWM and Philz touch recovery can void warranty and changes the download mode interface . any other way of completly backing up my phone so when i soft brick it or something i can install that like its a rom or something
