Hacking Flashcard firmware backups

[Technicmaster0]

I appreciate the help but I'm sorry I think I didn't explain myself the best way. I'm not trying to use another ds/dsi/3ds to flash the flashcard, I'm using an SPI programmer to flash the NOR chip directly from a computer because the flashcard is not being recognized at all by the ds/dsi/3ds, the backup bin files that I've seen everyone share here look a lot like what I need even tho I know everyone is using ds/dsi/3ds apps to flash and dump them I'm just looking for someone that may have the same flashcard as me to share me their bin file so I can try flashing it with the SPI programmer

Well that's a different story... but not entirely.
There won't be any good flash backups in most cases with unsupported cards. You would need someone else with the tools to dump the flash directly to get a proper backup.
You might find a backup that works with your card if you check the posts about unsupported cards but I wouldn't get my hopes high: https://github.com/ntrteam/flashcart_core/issues

I have several of them dumped from my personal collection, you can use them however you wish to recover your bricked flashcarts; whether they'd be clones or not, use them at your own risk, so long as you know what you're doing.

I found the firmware backup for the R4i 3ds R4iTT for 3DS (www.r4itt.net)
I'm sharing it for anyone who needs it.
