Nintendo has suspended the rollout of the 12.0.3 update. The systems that have received the update experienced connectivity issues, console bricking and SD card corruption.


Nintendo support just tweeted that the problem with update 12.0.3 has been resolved. If you encounter an error while downloading the new patch, you can consult the provided Q&A.

For those experiencing microSDXC card issues, the folks behind the Nintendo support Twitter account suggest that you "insert the microSDXC card while connected to the Internet and update the main unit according to the displayed screen."


Nintendo's support team has suspended the rollout of the Switch update 12.0.3 due to some unforeseen issues. The update 12.0.3 went live mere days before the company is scheduled to appear in an E3 Direct showcase.

The update in question went live on June 8 and introduced some run-of-the-mill stability improvements. Nintendo dataminer OatmealDome initially shared some additional details regarding the update:

  • package2 (contains OS kernel and key services)
  • SSL (helps w/ creating secure connections to a server - seems TLSv1.3 support was dropped?)
  • bad words list

At the time, it seemed like nothing very exciting would come out of the affair, but then, rumours of bricked consoles and/or corrupted SD cards due to the update started swirling around.

Nintendo support Twitter account sent out the following update regarding the 12.0.3:

"Currently, we are temporarily suspending the distribution of system version 12.0.3 of Nintendo Switch. If you are using the main unit that has been updated to 12.0.3, we have confirmed that network connection may not be possible depending on the environment. We are currently considering a response, so we are very sorry but please wait for the follow-up report."

"We have also confirmed that even if you try to use the microSDXC card for the first time with the 12.0.3 updated main unit, the main unit update is not completed and the microSDXC card cannot be used. Please wait for the follow-up report on this as well."
