Default [Q] Please nexus 4 shutdown. battery issue or unfixable cm11 problem???

please if someone see this. is it possible that the red light of death battery issue happened with 46 percent battery like 1 minute before. i was tweeting something and then it froze. i tried to press the home button and nothing happened. then it shut off and i haven't been able to put it into recovery mode or receive any feedback at all other than the red light of death. but i clearly remember checking the battery life like a minute before and saw that i had the 46 percent battery. is this defiantly the battery issue or could it be a software issue. im running stock cm 11 with the stock kernel. and whenever i try the thing where i hold the power button and volume down for a while then plug in the red light is either beeping on or off or just plain solid red.
would this fix it for sure? :http://forum.xda-developers.com/nexu...death-t2250454
