Trying to unbrick my R4i Platinum

I recently found my first flash card: the R4i Platinum from r4iplat.com. A few years ago it bricked and I replaced it with a DSTwo. Anyway, I thought it'd be nice if I could find a way to unbrick my R4i Platinum. It's yet another crappy fake, I know, but it's my crappy fake.

Anyway, the website for the R4i Platinum went down a few years ago. I can view it on archive.org but the downloads don't work. I'm trying to find the file called "fwupdate_for_143_drive.rar". This would contain the firmware update .nds file that I think I could run from my working DSTwo, swap in my bricked R4i Platinum, and run the update to unbrick the card.

If any other unfortunate souls out there had an R4i Platinum at one point and still has any of the firmware update files, I would appreciate it if you could send them to me. It's a shot in the dark, but I might as well ask

This is a picture of the card, btw: https://www.prlog.org/11699827-r4i-platinum-01.jpg

Thanks in advance.
