Phone restarting every 25 seconds
 

Hello,
I dropped my N900 in water while it was on. I immediately removed the battery and put the phone in rice for 48 hours. Now every time i connect the battery the phone starts automatically but freezes at the Nokia Logo screen and keeps turning off and on immediately every ~25 seconds. I can't turn it off unless i remove the battery, so i cannot really connect it to the computer. Is there any solution to this or is it even fixable?
Thank you.
P.S. Sorry if there was a thread with the same problem, but couldn't really find one with the exact same symptoms :)
