Looking for help with burned out Mr. Bulk Ti Dragon

[qmtu]

My dog placed an AW 18650 battery backward in my newly bought Mr. Bulk Ti Dragon light.
I saw a tiny flash and smelled a burned smell.
Looking at the battery contact, it looks a little melted.
When I screw the light back on, it turns on, but when it's completely screwed on, the light has a bluish tint.
I also have to unscrew the light to turn it off.

I don't know enough about electronics to know if the circuits are beyond repair, or if the melted part is contacting some circuit and shorting it out.
Any help I can get would be appreciated.

P.S. The light is a Seoul P4 emitter I was told, original to the flashlight.

Thanks

That blows, they are great lights and feel great in the hand.

Darn dog, no biscuits!
Can you take the head apart enough to get a clear shot Of the driver? I don't know much at all about these torches

I should have done that.
I sent it off to someone to look at.
If we have no luck, I'll post a picture when it comes back to me.
I was wondering if someone can diagnose it by the behavior, whether the melted battery contact is shorting out a circuit, or whether it's completely fried.
