Help

Downloaded bad vanir rom to my G2(came from 4.4 paranoid), i wanted that everything would be clean and moved my TWRP backup to computer, now i'm in problem because i cant mount usb in twrp and adb wont work either, I can go to download mode.

i dont have nothing to flash in my storage and i cant put there anything either. if i look up for devices in device manger i see G2 with "!" next to it. I cant solve problem by my self so hoping you guys meiby can help me out.
