Does anyone have or know of archives of firmware files? I need a specific file

Hi everyone,

So, LG is notorious for deleting files the moment their hardware is past support... anything to prevent you from retaining a device when you can be pressed to have to replace it. I have an older device and I have tracked down exactly what is wrong and how to fix it. Some folks have stated it's bricked, but much research has revealed that this is untrue. I need the stock firmware, but LG's site download links are all dead.

The device is the LG US730 (LG "Splendor"). The file I need is:
US73011b_03.S11b_03.P15107

If anyone has this or a previous version, I would so greatly appreciate it! I have spent many hours trying to track down the file from a mirror, an archive, a fan site, a site that has firmware backup files.... no luck anywhere. I figured it can't hurt to post a request just in case someone has it.

Thanks for reading, and if you can help, I would be in your debt and happily return the favor if you ever need anything that I have.
