Rooted for a few weeks -- rebooted and stuck on T-Mobile Screen + Random Vibration

Hello all! This is the second time this has happened to me, I've rooted my phone for about a week, and then for some reason when I decide to restart my phone -- it no longer boots up. It is stuck at the t-mobile screen and vibrates for a bit then stops, I have booted in to recovery mode and tried wiping that cache, but to no avail.

Any help would be appreciated -- or even how I can backup my data would be great too.
