Mariko V2 stuck on BOOT MOD?

[dethronermods]

HEllo I made all the installation (Mariko V2) perfectly fine without errors (Green light fine) on soldering but it keeps stuck on BOOT DAT screen
I formated my tested micro sd 3 times to fat32 but nothing happened. I've never update my Mariko (original firmware from factory) what can I do?

Are you sure your SD card is working good? Did you try on your computer? Which tool did you use to format it? I recommend Guiformat FAT32 for Switch usage.

If the problem doesn't come from the SD card, it is probably from for SD card reader. Are you sure you correctly connected it back after soldering the SX Core? It might be worth checking it again.

Let us know.

What version of boot.dat are you using?
Make sure to use the latest beta as prior stable versions have been know to have issues with the Mariko + SX core.

the previous post stating to check your SD card reader connection is also a must.
