Welcome to the forums!

Unfortunately, the scope of your problem (failure to mount /efs) is beyond the standard use of Odin and reflashing the stock firmware (even if the flash was successful it wouldn't fix the /efs partition).

Depending on the resources in your area you might find someone offering JTAG services that could fix it; or, someone that knows how to rewrite the /efs partition using Odin. Otherwise you could try Samsung warranty repair. Sorry.
