According to reports, it seems that some Switch owners who are using third-party docks have reported that their consoles have been bricked as a result. The dock in question seems to be the one created by Nyko, although there have been reports of other brands facing similar problems.
One of the reports claims that the gamer has been using the dock for several months, but following the update to Switch firmware version 5.0.0, that’s when the console started to bug out. The console initially gave off some error messages, but eventually stopped turning on completely.
The good news is that Nintendo seems to be well-aware of the issue and according to the gamer in question, when he contacted Nintendo, the company is offering to repair the console if it was under warranty, although any data recovery would be unlikely. On Nyko’s end, the company is looking into the issue and are working on a solution.
