Sprint Hero, not bricked but need some help!

[jeffy2walgreens]

Ok so I rooted my hero, but i accidentally tried to load a custom rom with out flashing a recovery image. So when i tried to do that, i forgot to uncheck the debugging setting. so basically its stuck on the htc screen. i can boot into recovery mode if i hold down the volume down button, but if i hit reboot, it goes back to the htc screen.

when i went into recovery mode, i read one of the lines and it says that there is no recovery image. i tried to run the stock RUU, but my computer will not recognize the device so the RUU wont run. does anyone have any ideas?

any help is appreciated. thanks
