Nintendo warned everyone in march: The Nyko charging dock doesn’t use the standard it should and therefore they can brick your nintendo switch.The release of the firmware 5.0 done it: Most peoples who used the Nyko docks got their console bricked!
Nyko is now being sued, by Michael Skiathitis. He filed a class-action lawsuit against Nyko in the US district court of central California. He lost all his save-data due to the bricking, even if his console was repaired by Nintendo.
As stated by the lawsuit claims, the docks “are prone to causing numerous problems to the devices that they are intended to support.”
Nyko has not defended themself so far.
They confirmed that numerous console were bricked, and that it could not had been prevented.
