The wrt routers have two partitions, firmware is installed on each, follow these instructions to switch over to the other partition and you may have working firmware there, although there is no way to be sure -

Power off router with power switch.
Turn power back on and Power LED will light.
As soon as all LEDs turn off (~2s), power off router with power switch
Turn power back on and Power LED will light.
As soon as all LEDs turn off (~2s), power off router with power switch
Turn power back on and Power LED will light.
As soon as all LEDs turn off (~2s), power off router with power switch
Turn power back on and allow router to fully boot.
It should now be booted to the alternate firmware partition
