[Q] G2 Soft bricked no ROM on Internal Memory topic

Hello All.. I have searching for hours not making much progress. Last night my LG G2 ran out of battery and I plugged it into the car charger and it soft bricked. I've been pretty busy lately so I'm on an old ROM Optimus DE 2.2. I don't have the ROM saved and I've been trying to ADB sideload the ROM back onto my phone but in the command prompt it says device not found. I tried installing some generic drivers and that didn't work. I tried the LGUnitedMobileDriver and that isn't working either.

I'm not sure what to do next. I have ADB on my computer and ADB sideload on my TWRP recovery, so I would like to push the ROM on my phone so I can flash it without having to wipe my phone. What drivers do I need right now my phone shows up under other devices in device manager. Or am I sideloading wrong? Any help please lol..

I was caught off guard because of the random soft brick. If I would have been working my phone I would have had the proper backups made. Thanks for any help, it is much needed I need my phone back ASAP!! Thanks again.
