Well its a long story........
First, I bought a LG G2[F-320k] few months earlier . I gave it to my friend and he rooted it and maybe he was using a custom rom[not sure].
Second, I got it back 1 week ago, I saw few changes like, battery icon,status bar color,navbar height but no xposed framework installed so maybe that was a custom rom. Cant contact him anymore!!!!
3rd, I tried to get some software updates but no option in about menu, tho I decide not to take kk update as it tone down benchmark scores.
4th, then as it was rooted I tried the camera mod of G2 but wrongly downloaded and installed the kk rom one. And bricked my phone[bootloop].
5th, then I flashed it with F320k11k[JB 4.2.2] using flashtool 2014, wanna do the CSE Flash but that option didn't popped so did a Normal Flash.
6th, I rooted my device using Kingo's Root. After that I installed xposed Framework and G2 Tweakbox from Play store to modify navbar and status bar.
Now my battery of phone doesn't last more than 12hrs which was 1day and 12hrs before. I uninstalled few bloatwares and battery increased 3hrs. And lags everywhere! Settings menu, home page. When ever there is something to scroll in the launcher[Contact,music etc and other 3rd party apps didn't lag while scrolling] its laggy/hickup.
Pls help me!
One more question why kingo's root wants me to give root access to ADB Shell[I did give but dunno why should I give it] using SuperSU!
Note* I tried iOroot but it doesn't work for me!
