Think I bricked my phone

view story

http://forum.xda-developers.com – SO I am hoping to get a second opinion, but I think i bricked my phone. I rooted my HTC EVO 4g LTE and installed Mean Rom. I am a tinkerer and decided I would try one of those nightly CM nightly builds. I downloaded, restarted to bootloader, installed zip from storage, wiped cache and davlik cache, rebooted AND... Nothing. Black screen for 30+ minutes. Restart phone and start to bootloader and go into recovery and sdcard2 is... Completely empty! MeanROM, CM, everything is gone. Reboot phone again, again black screen. Pull SD card and put MeanROM on it and now it won't recognize in team (HowTos)
