Storage [Q] Recovering Pictures, Contacts, etc...

My Vibrant shutdowns after few seconds of showing the unlock screen after booting up, no matter what I do the phone looses power. I can boot the phone into system recovery and keep it on but I'm unable to mount the phone's memory to the computer via USB. The previous owner rooted the phone and it has ClockworkMod Recovery v2.5.1.2, I'm able to perform backups but no way of getting out of the phone. Is there a way I can recover my data? I will be getting a different phone so the idea is to get the data out. Thank you.
