Hardware Switch Bricked?

[bhccm]

I was playing a game and then suddenly its gone. An black-white error screen and mario kart closed.
I'm using sx ox, off line. Never got online. Charged it, used the dongle again but no response. try to hold 15seconds too. Nothing.
Charged with different chargers. Nothing.
Any one?

Did you have AutoRCM enabled?

It is likely in RCM mode and you should try to boot it by hekate payload.
