New3DS bricked (black screen and blue light staying on)

[Slexer]

Hello everyone.

A few years ago i bricked my New3DS in the process of installing CFW.
If i try to boot the 3DS i get two Black Screens with the Blue Light staying on. No Sound what so ever.
It only turns off after holding the power button long enough or removing the battery.
Because i was a dumb little kid back in the years, i formatted the SD-card in panic.
I dont know which CFW i wanted to install because that all happened so long ago.
Sadly i also cant remeber which firmware was installed on the 3DS.
I looked up tons of threads in forums now and tried multiple fixes.
Things i tried:
Booting while holding either Start or Select - nothing happened, still black screen.
Formatting the SD Card to FAT32/MBR as Primary and putting the latest version of Luma3DS into the root of the card, then try booting - nothing happened.
removing the wifi-thing for 30 seconds and connecting it again - nothing happened

Thank you for your answers!

Try ntrboot to install B9S (or at least start GodMode9)

The only thing that is promising.

Removing WiFi thing? Only the old models have a removable WiFi board (but your thread title contains "New3DS bricked")
For the old models: They won't boot without the WiFi board correctly connected (and trying a different WiFi board is a good idea).

Do you have a flashcart, DS, and a nand dump? try to use NTRboothax and reflash it from there

Sadly i dont have a flashcard which supports ntrboot. If there is no other way i will buy one. Could you give me a detailed explanation of how to do it when the card arrives?
Thank you

Okay i dont really know what exactly i unplugged there but i guess it wasn't the wifi board then. xD

I know of no other way. You could say this is the official way; the way Nintendo did software repairs (we can only do it since a signature check bug allows our own carts to boot with ntrboothax)

Detailed explanation? Why reinvent the wheel? Ntrboot is already described on The Guide.

The same thing happens to me as to him, only that I have already tried the flashcart (R4-SDCH-Gold Pro 2021) using the ntrboothax method and it has not worked for me. When starting the gm9 it freezes on the boot screen that says booting, however if I remove the sd card from the 3ds it does enter the gm9 menu, but I can't do anything since I can't access the .firm necessary. If once started I put the sd when entering any menu option it automatically freezes again. I have tried ntrboothax on another console with the same flashcard and if the gm9 boots correctly, I have also tried with different sd. I do not know what else to do

Thanks in advice

For me ntrboot worked without problems. Did you format your sd card into the correct format?

 

[vendofincas]

yes, in fat32 32kb, and I have checked it with h2test with no errors

did you follow this guide? 3ds.hacks.guide/flashing-ntrboot-(3ds-multi-system)

No. I actually followed the NDS guide:
3ds.hacks.guide/flashing-ntrboot-(nds)

I used a DSi to setup the card.

Ah okay. Anyway, the process in the broken 3ds I think is the same

I don´t know what else to do
