KR/WA version back to MTA version?

[tomasmp3]

I updated my K5 to the WA version (latest)... then realized I needed the MTA version! I really need to go back to the MTA version. However, I cannot seem to do that. I went to the Samsung site and got the latest English version, and put the files in the root folder, and restarted (even reformatted then placed files in root), and still have the Korean/World version. I really need to go back to MTA. How do I do this?? Please help!

Thank you.
