NS2 bricked after power failure?

Hi there!
I have been using and upgrading the fvdw-sl firmwares for over a year now without any problem.
Unfortunately my son pull out the power cable from socket by accident and when he put it back the ns2 looks stacked.
During power up, I can hear some hard disk spinning, some minor blinking and that's all. Blue light always on. No connection with dhcp server. On router's interface looks like its IP is 0.0.0.0 (It had a static ip when it was ... alive).
I dont remember last firmware, possibly it was 12.1
I have pressed power button for more than 10 seconds, nothing happens
Any help please. I hate to make a clean install again.
Thanks ab front
