anyone who knows on how to reflash dead bios.

try to put jumper in a cmos battery. make sure its unplug from ac

I already tried it. but it not working.

are you update the bios?

Yes. After I update. it got bricked.

I think you need to go to service center of your motherboard.

whats the brand and model of your motherboard?

From my own experince if you have bricked Bios it normally means it's gone dude, but in saying that what's the exact model of the board i can try assist you but doing what was mentioned above normally fixes the issue if doesn't i'm affraid it's bricked is it still under warranty and how did you brick it did u try to flash it with another bios or did u accidently turn off the power during flash?

try this method hope it work
