Overview

• Nintendo's 20.0.0 firmware update earlier this week introduced Virtual Game Card support and prepared for the Switch 2's GameShare feature.
• Shortly after the update, some users reported their consoles becoming unbootable due to error code 2206-1015, causing a black screen restart loop.
• Nintendo quickly acknowledged the issue on its Japanese support account and released the 20.0.1 update to address the problem.
• Affected users must boot their consoles into Maintenance Mode to manually install the 20.0.1 update and restore functionality.
• The 20.0.1 update is optional for users who did not experience the error, as it solely fixes the boot-up bug caused by the previous update.
