Unable to Reflash via LG Flash Tool

Hey all, thanks for reading. I've caught myself in a predicament. I can solve most issues that crop up my way, but right now I'm a bit stuck. It is likely fairly simple and I am just dumb...



The huge issue here is that I am running stock lollipop for the D415 model. I am having the typical base-band and WiFi issue that a lot were having. Like most, I just booted up into TWRP and restored a backup. I Wanted to try again so I flashed the stock ROM and tried again; didn't work...oopss..



LG Flash Tool refuses to locate my device. Download mode fails to connect my device properly. Error is:



EP1/out FAIL nfo=40 pg0=ffbd880

usb_read() transaction failed



So now I am stuck with a broken stock ROM, no TWRP, and no current way to re-flash a stock KDZ.



Steps taken so far:

1. Reinstall all drivers

2. Attempt to root and install TWRP to access my backups (No access to Download mode)

3. Started all over with original USB.



What can I do? Thank you again for reading my long post.



EDIT: Forgot to include that I see the proper devices in device manager.
