So how can i reprogram it, if machine doesn't boot? in the istruction it says

Insert your USB stick, then power on the device whilst holding Option ⌥

You MUST get an SMC which can boot the machine.

For example, 00165 SMC can do that.
But needs to be reflashed, because lost the sound.

New/empty SMC is useless, I already told you.
