Question help with

Can someone help me with creating an that will flash a set of files over /firmware ? I have like no experience in creating zips but really need this to permanently unbrick my s3.
Probably sent from my Galaxy Nexus running CM11, or maybe from my Galaxy S3 running Slimkat...either way it was sent from something with OLED and a custom ROM...even my computer with custom compiled Kubuntu...
