Any way to get back to stock without USB port/odin?

http://forum.xda-developers.com – My phone's USB port is borked...as in not working....I'm running BluKuban with CWM installed. Are there any update.zip files that will get me back to full stock so I can take the phone into the sprint store? I can't use Odin as nothing I plug into the USB port works. But I can use WiFi and Airdroid to get a file over to the phone if I can keep it connected long enough. (I'm using a third party charger with some spare batteries to keep running for now.) Any help is appreciated. (HowTos)
