SBG3300-N bricked, how to recover back.

mlml139

my SBG3300-N bricked, 4 lan port can used as switch, Plugging an Ethernat cable from router to PC, connection light comes ON but no IP address is assigned to PC, tried assigning address to PC in the range of 192.168.1.x manually and couldn't ping the router on either .

Was wondering if there is another procedure to restore the firmware? maybe via USB or using some application that can access the router over some different protocols?
