[LG G6 Guides, News, & Discussion] network-samurai:
They must work with waybackmachine because the page was setup to redirect on page load no matter what. I have bypassed it by loading the file locally and removing the body onload function.

Which reveals the pages core functions, which I have identified this following line of particular interest, which I have amended to include the LG domain.

var target = "https://developer.lge.com/resource/mobile/common/file/DownloadFile.dev" + "?fileId=" + encodeURIComponent( json.fileId ) ;

I believe this could possibly be reverse engineered to give us a direct link to where the files were originally hosted. I have probed the URL above which still appears to be active. The JSON component is the file ID of the file you want to download.

There are other functions present which may also interest others. I recommend reading directly from the source (ARCHIVE.org DEC 6 2021) as I have modified these functions to point to LG's domain for - probing purposes :alien:.
