LG G2 (d800) Stuck in Bootloop
Try flashing this zip (the xposed disabler attached to the OP) in recovery. You can also try repeatedly pressing any hardware button during boot until the phone starts vibrating. Xposed will have entered "safe mode" when it vibrates for a longer duration. From the post:


  Quick explanation of the safemode: It was developed by @Tungstwenty and makes it possible to disable Xposed by repeatedly pressing one of the hardware buttons during early startup. The phone will vibrate twice when the first key press has been detected. Then you have five seconds to press the same button four more times. Each key press will be confirmed with a short vibration; the final one with a long vibration. It creates /data/data/de.robv.android.xposed.installer/conf/disabled, which prevents most of Xposed’s actions (e.g. no hooks are made and no modules are loaded). There’s no 100% guarantee that this will get you out of a bootloop, but in most cases it should.
