How do I full reset my phone?

[AC Question]

Hi,

I tried to install TWRP and wipe data to install Sultan ROM on my Oneplus One. I am extremely stupid and wiped everything. However, now I have no OS, and forgot to move the ZIP file to my phone to flash before doing so. When I plug in my phone to my computer, my computer does not recognize my phone, so I can't move it over. I just want to completely reset everything and have an OS, or figure out how to make my phone show up in my computer. Please help!!

Thanks.
