Hacking New 2DS Wont Load R4 Cart

[Aeecee]

I just bought a R4I BS9 cart and used it to install Luma on my New 2DS and got it working just fine. But now I wanna use the R4 to play DS roms and my system wont detect the card when I put it in the system.

Since the cartridge arrived flashed with B9S, you won't be able to use it to play DS games until you flash it back with it's original flashrom.

You can find a guide on how to do this here, along with a table telling you which card requires which flashrom: https://3ds.hacks.guide/installing-boot9strap-(ntrboot)#section-v---removing-ntrboot

Please do note that the flashrom links are magnet links, so you will need to use a torrent client to download them.

If I do that will I be able to flash it back to BS9 in the future if I ever need to install custom firmware again.

Yes.
