I rooted my G2 before in 4.4 Kitkat, then I have updated it to 4.4.2 without a problem. Then I used an application that gives you option to turn off camera sound(because I use F320L, it is a Korean version of G2 where camera sound cannot be turned off).
After using the patch(which didnt work) when I run SuperSU application, it gave me error saying "There is no SU binary installed.."(screenshot attached). So I found a way to flash back to stock rom and I have successfully flashed V11G(4.2.2 JB). Then I have rooted my phone on kitkat(4.4) but the binary error is still showing up.
Is there any way to fix this? I am new to android and in desperated need of help!
