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.
- 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."
The team is still working on the fix and we'll be sure to update you on the development.
