The Switch 20.0.1 system update was released on May 2, 2025 (UTC). This Switch update was released for the following regions: ALL.

Security flaws fixed: <fill this in manually later, see the updatedetails page from the ninupdates-report page(s) once available for now>.

Official ALL change-log:

Fixed an issue where Error Code: 2206-1015 sometimes occurred when restarting the system after updating to system version 20.0.0.
If you're encountering the error, update your Nintendo Switch console in Maintenance Mode.

NPDM changes (besides usual version-bump): none.

RomFs changes:

No changes.

The only changed function was L_dce70.
- This function iterates through "tmpCache" and attempts to shrink all JPEG images with ShrinkJpegEx in a loop.
- However, the objects holding the JPEG file context were being freed unconditionally which resulted in passing invalid arguments to ShrinkJpegEx which, in turn, would return the error code 0x7EECE (2206-1015).
- The issue was fixed by first ignoring any error code returned by ShrinkJpegEx and then properly implementing the conditions that lead to freeing the JPEG file objects.
