Linksys wrt1200 AC main partition bricked?

Hi all,
my main partition with openwrt suddendly became dead, no wifi, no ethernet, nothing.
So i booted the second partition of the linksys wrt1200 AC, to reinstall openwrt again(by updating the img file in the custom linksys page), but seems like nothing works, everytime i boot the main partition nothing works.
did i brick it ?
do i have to use the pins on the board to recover ?
