Why Is My LG G3 Lollipop Phone Stuck In A Boot Loop?

[AC Question]

I Tried Rooting My LG G3 Lollipop Phone But When I Turn On My LG G3 phone It's Just Stuck In The Power On Screen Where It Say's "LG Life's Good Powered By Android". I Tried Taking Of The Battery Putin It Back On My Phone And Turning It One But It Still On A Boot Loop. I Also Tried Factory Reset And It's Still On A Boot Loop. And I Also Tried Installing Items For LG G3 And Plugin My Phone On My Computer And Disabled Root Methods But It Won't Work. But The Real Problem Is I Don't Have Warranty On My LG G3 Phone. I Guess I'm Buying The New LG G4. And Can Anyone Help Me With This Problem Please.
