yeah, that's a weird bug with OMNI right now -The phone isn't really OFF when it's off. It shows the questionmark and gets very hot, and it won't boot while it's plugged in. I have submitted a jira report, which just got downgraded to minor. You have to unpplug the phone from any usb charger or port and hope that it has enough juice to boot. Then leave it charging while it's ON.
I'm not sure how to recover from a dead battery in this case, unless the battery-out download-mode thing works? give me fifteen minutes and I'll try it...

I've been having charging problems ever since installing this ROM. When I plugged it in before, it would show a battery with a question mark. The phone eventually died and it won't boot up. I am not really sure what else to put but just ask and I'll answer.

if your battery really is too low to boot the phone, then the only option I'm aware of is to ODIN it to stock and start over.
1)remove the battery
2)plug the phone into a pc usb port
3)hold vol+ & vol- & power until the warning appears
maybe someone else knows some trick way to charge a battery out of the phone.
