I have installed CloudyStock 1.3 ROM in my LG G2 and also installed simple kernel v1. I am interested switching to CloudyFlex 2.1 and how should I switch to Cloudyflex and also the kernel to normal one? Please help me.
Well you switch pretty much the same way you install. Download the ROM of your choice and (since you're already on the kk baseband because you're using cloudystock) flash in recovery. Wipe from front to back and then flash the ROM (cloudyflex in your case). If you have intentions of maybe going back to a jb based ROM, simply flash the ROM of your choice and flash your device specific baseband/modem after the ROM or before you reboot (as I have been doing) and wallah, magic.
As far as kernels go, flash it as you did when you flashed cloudystock (assuming its designed to run with the ROM)
