HTC Vivid bootloop, how do I fix it?

My phone got wet a while ago (weeks ago) but still worked just fine, until one day, I dropped it [not far] and it completely conked out.

So since then it's been in this infinite bootloop. As soon as I put a battery in (I got replacement batteries), it vibrates, goes to the htc screen, then shuts off.

I've tried hard resetting it as well. I get to the screen, and tried factory reset, and recovery, but it does nothing to help, and the phone goes back into the bootloop.

Also
-The battery charger doesnt work, the charging light turns on for a few moments, then turns off,
-There's a weird faint light next to the LED notifications light.
