3DS cannot boot at all even after doing new setup and buy new card

[knotty sigil]

I would like to ask if anyone knows why my 3DS cannot boot like normally and how to solve?

So, a few days ago I just started to use my 3DS after years. It didn't boot at first, it only shows blue light but black screen. But then, it was solved (SD Card matters) and my 3DS able to boot for a moment and able to play some games.

Yesterday, I keep turning on my 3DS, it was booted but it said that no SD Card detected. After checking to computer, I just found out that my SD Card to my 3DS is corrupted. This answers why I cannot go to "Luma" software and back into the default menu with no apps installed.

So, I bought a new SD Card (it's guaranteed, not replica) to install the 3DS Luma from zero. I tried a lot of threads and Youtube videos suggestion that are pretty much similar. I did install Luma, bootstrap, updatest gm9. Cannot do with Luma, I tried Gateway (the old way of CFW), my 3DS still not booting. There's no problem in the hardware, my 3DS was booted.

If anyone will, please help me... Thanks in advance

Yeah don’t use gateway that has bricked consoles

The console won’t boot if it doesn’t have luma on the nand, if it doesn’t it looks on the SD to boot

How to have luma on the nand?

I don't have any data on SD card since I bought a new one, then fill the card with this data

Except boot.3ds and boot.firm because I was following the tutorial, but I tried to have both boot files and still not booting.

My 3DS had Gateway CFW when I bought, but it was able to change to Luma, even days ago I can still use to play

Neither of these screen is work. I tried push select while booting, I cannot access Luma menu

Can you open godmode?

[knotty sigil]

Also cannot 🥺

That’s bad

Luma 11 copies itself to nand. Sd card needs to be properly formatted and partitioned to be used by 3ds

Luma 10 is way old, and broken on newer firmware

Yes I have luma 11 boot files on my SD card, but no good 😣

The Luma 10 screenshot shouldn't be possible then

[upbeat iris]

They were showing an example I don’t think it was on their console

Sounds like SD card has a problem or the reader on the console does

Show disk management in windows and how it has the SD partitioned

I'd wager there is an unallocated partition at the start
