While opening camera in my asus zenfone2, it shows a black screen and suddenly exit from camera application (The device got authorized service from asus twice, and after second service, the problem arised. May be due to camera driver errors). Everything functions perfectly except camera. So, I am trying to root the phone and need to install cyanogen-mod in my device. Does this operation solves camera error? Please, tell me how to root and install(TWRP) recovery in asus.
