Power Button and Volume up while the usb cable is plugged in.
Im gonna work it out today i will try and put my over lg g2 in your state and fix it and i will upload all the steps needed but if you have good luck with any over solutions let me know
I had this problem too, i think it was either by accidentally flashing a stock kernel on cm rom or trying to switch from cwm to twrp.
But please dont destroy your device
Also btw there was a guide mensioned in this thread i have seen it before and i have had problems when using a virtual machien infack i clean install ubuntu on a old laptop and had sucsess with it dont know why but if you have an old pc laptop hanging around clean instal ubuntu on it that fix guide may now work that way if you dont have anything lying around dont wroory im onto a work around for you
I used VirtualBox on my mac to set up ubuntu from zero, did work fine for me.
