verizon soft brick help

[AC Question]

My lg g2 vs980 is soft bricked. it repeats the same lg logo and my download mode will not work, when I connect it to the pc it says not found. Once I get my download mode I know ill be able to get the stock operating system back. I just need to find a way to get my download mode to work. Also I've already tried to command prompts but I keep getting the message saying no more space.
