I recommend you to use the latest version of CWM or TWRP recovery, as the SlimKat custom ROM has been tested on the AT&T LG Optimus G only by using the mentioned custom recovery images. Don’t worry as CWM recovery is the most popular custom recovery used by worldwide Android users while TWRP recovery is the touch version of the same.
