Unrooting HELP A NOOB OUT

[TayGotThatLuck]

I decided to try and root my HTC Evo 4g LTE. I rooted it sucessfully but failed to notice that it wasn't an S-off root by that time i had already tried flashing a new rom (failure i know). So now my phone doesn't load an OS and just goes to a black screen after the main "HTC: quietly brilliant" screen. i have no idea how to fix this i've tried finding an RUU to work but nope, it doesn't work.
i'm running Hboot:2.09.0000


CAN SOMEONE PLEASE HELP ME!!
I just want my phone back

Do you still have an unlocked bootloader with your S-ON?

Actually I fixed it ... I'm s-off now but I don't know what I should do with it now .... There's too many ROMs out there don't know which one I should try
