W580i: water, then "bricked" after master reset

Hey everybody,

I'm back after a year or so... haven't been on this forums since I gave the phone to my mom for use...
This is what happened: some water splashed over the phone and then I wiped it off... didn't think it was much of a damage until it stopped picking up a network... it showed me all the bars but AT&T didn't display... now that I remember correctly, I modded that part, which would get rid of the AT&T logo on the home screen...
All I know is that I wasn't able to call or receive calls from it... also the skin was acting somewhat weird... think it was the strobe skin...
I for whichever reason then decided to do a master reset, now it doesn't work at all... It directs me to a screen shifted to the top where i can only see "OK" and "Back/Cancel" I think... the top screen which probably contains a question is hidden.

So many problems at once, what's the first thing I can do here? Can I flash this thing to default settings and then see whether there's something wrong with the hardware?

We haven't found a spare phone yet...Please help! thank you!
