Help Please!!! Bricked Phone

[redcapevillian]

I tried to use the Nexus Root Tool Kit to root my phone. While using it I was in recovery mode and started messing with everything because I could not find the .zip file for super user. Doing this I wiped out the OS and I did not have anything backed up. I am very novice when it comes to this and don't understand all the terminology but thought it couldn't be too hard to root my phone. I need help please to at least get back to stock.

Hi I did something stupid, I did a factory data reset and usb storage erase on my Samsung Nexus S 4G. I lost all my recovery and zip files. I can access bootloader and twrp but have no way to flash a new zip. When i plug my phone into my pc nothing happens. This has happened to my HTC Evo 3D but all I did was take the sd card out, but with this Nexus there is no SD card. So how can I push a file to my Nexus from my PC?
