Hello.

What was initial state of the phone? Was it booting correctly?

Try to make Factory Reset and Wipe cache partition from Recovery Mode. If problem will remain the same - try to reflash the phone.

If "E: failed to mount /efs (invalid argument)" error still remains in Recovery Mode - You can try to manually write EFS of another, correctly working SM-A500FU.
