[Q] My phone seems to have suddenly died topic

So I sent a text before dinner, put my phone down on the table, and ate. When I finished and tried to check my phone, it was off. The power key is unresponsive, along with no vibration on hold. I've done all the possible button holds for about a minute. It doesn't seem to register at all when plugged into the computer. I have a crack in my screen from an unfortunate drop about a month ago, so I know RMA is off the table.

Is there anyway I can fix this, or is this a case of ponying up for a replacement?

PS: It's also rooted, with CF-autorooter if I remember properly, with stock 4.4.2
