[2informaticos]

Any history available?
It is recognized in DFU?

 

[yobad]

I can't enter DFU mode, but always I have error when I try revive or restore.
The MacBook was filed with dust and nicotine vapeur It was to dirty inside.
When I removed the motherboard and cleaned it works for once after the ultrasound cleaning it return back in the first state.

If stopped working after ultrasound cleaning, you may have knocked off component, or broken trace.
