[LG V20 Guides, News, & Discussion] YoMama25:
I'm also running into the USB Not Found issue. I have tried multiple cables, multiple ports and two separate computers. I'm on 10p already, and I just downloaded FWUL two days ago. Is there anything else I should try?

Flashing... this will take a while.
Flashing TWRP to lafbak. Please wait...
