My dsi Is bricked

[unu]

OláHello everyone, I need help with my ndsi. I recently uninstalled unlounch after I wanted to format my console and it gave me an error screen in Japanese and after that I didn't When I turn it on, the LED just stays blue and there is no image or anything. I have already tried combinations with the buttons and I have already removed the battery and nothing has worked. I have my Nand saved on my PC.

I don't know anything and can't help you, but I did want to give you a massive shout-out for such an appropriate avatar!

DSi NANDs are known to be made of hopes and toilet paper, and fail more often than a temper trying not to fall for bait. But fear not, you can solder on a microSD card adapter [I think?] in place of the dead NAND and write your existing backup to it.

You can try NTRBoot:

Uninstalling an unlaunch error is usually an Error+number on the screen.
Did it go wrong after uninstalling unlaunch?
If not, it is also possible that the wifi board is causing a malfunction(error screen in Japanese and blue LED)
Try replugging the WiFi board.
