Yeah the reason bricked phones go for that price is because the digitizer, LCD, keyboard, it all still works. It's just the mainboard that's toast.
Yeah, sorry man, I'm out of ideas. I mean your phone can't be TOTALLY bricked, it can boot into the bootloader, there's got to be some way to fix it. I just don't know how you would do that. You know what, actually, I have an idea.
Use 7zip or winrar to extract recovery.img from ESPRIMG.zip and go into fastboot and fastboot flash recovery.img. Here's a guide:

Scroll down to the guide for flashing a custom recovery. This MAY not work because you are s-on still I'm assuming, but we do have an engineering image I believe, so it MIGHT work. Worth a shot at least. You could then you might be able to boot into recovery and flash clockwork and then be able to get your phone working again.You could also try fastboot flashing other partitions in the ESPRIMG.zip but start with recovery.
