Many thanks to Buddy Lumpkin, Christopher Dupre, Audet Benoit, and John McIntire.

John McIntire and Audet Benoit suggested reset the resetting the NVRAM to factory

Buddy Lumpkin suggested reprogramming the NVRAM.

I've tried both suggestion but didn't work me.

Christpher Dupre suggested replacing the chip.

The chip is on the way.
