    What happened to my comment? You took it off?

    All I was telling you is that your instructions require a .tar file and that is not there; so either put the .tar file in the download, or change your instructions so that people understand how to load a .zip file on Galaxy S4.

    The file(s) you offer for download are simple .zip files… the instructions you provide are for .tar file! Please make up your mind and publish a correction soonest…you are confusing a lot of people with this!

    This is not an ODIN flashable firmware… they are simply ROMS. Please fix text.

    Once you download these files,and extract them there are no tar files. hence you would need to load them on to your phone via a custom recovery, such as TWRP, or Clockworkmod Recovery. you can only do this if your phone is rooted. Unfortunately with the update that went out from AT&T in the last couple of days ,that would be nearly impossiable.

    You realize these instructions are wrong?

    These are not Odin files, they are CWM recovery zips …
