[Q] no su binary installed lgsm323. SuperSu cannot install it. topic

hey there my lg l70 was rooted up untill updated to 4.4.2. There is no SU binary installed and SuperSu cannot install. This is a problem. If you just upgraded to Android 4.3 you need to manually re-root-consult the relevant forums for your device.
This is the message i receive from SuperSu. If you can please assist me as i am new to this i would greatly appreciate it. The info on my phone is: lgms323,android version4.4.2,kernel version 3.4.0+,software version MS32310c
