Macbook A2179 Internet Recovery

Customer tried formatting and it failed.
Now it will only go into internet recovery whether I press any key combination. It will not boot up from an external drive as well.
I getter error 2005f 2002f.

What should I do?

I tired disconnecting the Touch ID and also the small board as well. Still the same.

I can't get into diagnostics or target disk mode.

the device did have an issue where the output would automatically go to headphone mode and had to be changed manually to In built speakers

"the output would automatically go to headphone mode and had to be changed manually to In built speakers"
So it boots into macOS?

That was before customer tried to format it to resolve the issue.

Did you try DFU restore?

Yes. Tried Revive / Restore both.

DFU completed without errors?
Did you try internet recovery with ethernet connection?
