N910A OC4 4.4.4: Failed to moutn/efs problem

I got this Note 4 N910A OC4 4.4.4 version which it seems somebody in town who named his business as "Cellphone Doctor" messed with this phone’s EFS. I guess he conducted a failed surgery on this phone :):)

Anyways, I flashed OC4 4 files with Odin and Z3X, but failed. Honestly I don’t know what to do next. I believe I need a working N910A EFS file but I am not positive about that.

Any help and input will be appreciated. Thanks!

After flashing the 4 files, I got this!
