MicroSD Card Problem with B9S System

[Zamoksvaqi]

Sorry guys, I am first on this web and a noob.

Things here: I made the latest version of B9S, successfully, the system updated to Sys 11.15.0-47U, I can play my game. However, the MicroSD card is so small (4GB), so I took another one (32GB SanDisk SDHC 1 U1) from my cam. I checked the card, which is genuine for sure, and I formatted as said on FAT32 vector 32 whatever I don't know but following the rules specifically. I inserted it into my baby New3DSXL, I push the START button, the blue light flickering once even less than one second and ... ... there is no and. I tried other way: I turned on my machine, and inserted my card with power on, suddenly, the screen told me that COULD NOT DETECT A MICROSD CARD. THE SOFTWARE ON THE MICROSD CARD COULD NOT BE DISPLAYED.

I don't know why, the card can be used any where else, and it is working smoothly. Just cannot be inserted into the back.
Can someone help me with it? It drives me crazy now. Thanks.

Sound like you are missing boot.firm, grab the latest boot.firm and put on the root on your SD

Did you follow https://3ds.guide , or did you follow some random Youtube guide?

Your 3DS will not be able to boot without an SD card unless Luma is copied to the CTRNAND, as in https://3ds.guide/restoring-updating-cfw .

Don't you think it's important to say exactly what you did when you're trying to get help? How did you check the card?

Also, was the card empty when you inserted it into your 3DS? When you are upgrading to a new card, you are supposed to copy the contents of the old card over to the new card before you put it in your 3DS.
