Default [SOLVED] HTC Rezound: Stuck on htc splash, s-on, unlocked bootloader

I bought my friend's used HTC Rezound he was selling to me for 15 bucks. He said he "broke" it by flashing a bad ROM, and he doesn't feel like fixing it because he already replaced it with an LG G2. I figured for that price, fixing it was worth a shot. Besides, I'm coming from a Rugby Smart, and by the looks of it, this phone is a LOT better specs wise! Anyway, I can't seem to figure out how to fix it...

So when the phone is powered on, it goes to the HTC white splash and freezes there. The only way to get it off is pulling the battery. I CAN however, boot into the HBOOT menu, go to recovery, and all that stuff. So I guess what I'm trying to do is restore this to 100% stock at this point. Apparently in order to do that, I need to make sure my bootloader is locked and "S" is set to on. My "S" is on, however the bootloader is unlocked. Can someone please explain to me how I would go about fixing this phone, in a step-by-step fashion (if possible)? I would normally know what I'm doing, but this is the first HTC phone I've had, and I don't know how to use HBOOT, let alone RUU's and all this other stuff I read about for restoring this phone to stock.

Thanks.

EXCITING UPDATE: I found out how to use fastboot to re lock the bootloader, so that's done now. Also, not sure what i did, but now whenever I try to boot into recovery it gives me a security warning and I can't access it (so now I have no way of flashing ZIP's, unless there's some way of using the fastboot command on a computer to do this). I'm no expert on HTC's, but I'm getting the feeling this recovery issue seals the deal that this phone is not getting fixed, but I guess we'll have to see...
