Thumbs up [Q] Error while trying to update OTA or using SD card method

When trying to update I get the following error. I need a clean copy of the dexdump file for Sprint Galaxy S3 on v 4.1.2 (MD4)

Thanks in advance if anyone can help. Also, what is the easiest way to copy it to the phone?

Verifying current system…
“/system/xbin/dexdump” has unexpected contents.
E:Error in /tmp/
