Default [Q] Help in getting back to stock.

Hello ladies and gents,

I am hoping that you all can help me. I recently had a hardware malfunction on my verizon GS4. It was (is) on MDK firmware -rooted - with CWM- and Eclipse TW 3.0. I need to reset it back to stock as I had to get a warrenty replacement. The kicker is I cannot use the USB port. I had a back up of the stock rom. However that leaves me rooted and with CWM. Any help on how to get this back to stock?
