Hacking Question BlackScreen after using ChoiDujourNX with wrong Format (Mariko Switch)

[Melvin971]

Yesterday ive tried to update my Switch (Mariko) (SX Core) with ChoiDujourNX,
I didnt knew that this wasnt a good thing to do.
My issue is that my Switch doesnt turn on anymore and only a purple/pink light lights up[should mean that SX Core cant communicate with the NAND](screen stays Black).
I made another mistake but accidently flashing FAT32 instead of exFAT which was the format of my SD Card. Ive tried to convert my
SD Card to FAT32 and see if it boots but i didnt help.
Ive got a NAND Backup but I dont know how to flash it without even getting into SX OS.
Any suggestions how to fix my Switch?

Update your SX chip to v1.3. Several people had similar issue and gone with that.

Sadly that didnt help at all, still a pink light.

Can you post pics of your soldering points?

I updated my Switch Mariko using ChoixDuJour without any problem, my microSD card is in FAT32 so I chose FAT32 when flashing. I think there is no problem with ChoixDuJour if we use the lastest versions of sx core and sx os

@iialaq01 Cant be the soldering points as it happended right after the ChourDujour Reboot.....pressed reboot after that the switch shut down and then nothing else happend the screen just stayed black. But anyway id send a picture in here if my switch wasnt in a repair shop atm

You were using emunand, right? You weren't trying to run this on sysnand?

Try this. Force power by holding power button for 15 sec. then try powering it without the SD card see if you can have the boot.dat on screen. If still same, try disconnecting the modchip cables and put the nand back in original place and try powering see if it works normally. Other than that the only thing that I can think is shortage somewhere in mobo

@hartleyshc I ran it on Sysnand. Didnt work without the SD Card either which is weird......Im going to disconnect the Modchip tomorrow and ill let you know if i fixed it in the next few days. Thanks so far!

No we can only run ChoixDuJour on Emunand, to update Sysnand just turn on Wifi and update as usual

ChoiDujour is a PC program that can only be utilized by sysMMC.
