3DS firmware 11.8.0-41 out, is actually stable and broke support for Luma3DS - fix now available
The 3DS is reaching its twilight years, with major first party releases slowing down. Updates to the system software are also becoming more and more uncommon. However, Nintendo sent out an update tonight, once more boasting about its beloved stability updates. This time, the claims were actually true, and the new update broke support with Luma3DS. Smealum, a major force in the scene is currently telling users to avoid updating at all costs, as doing so while having Luma will result in a "Failed to apply FIRM patch" error. For now, its recommended to stay below the new 11.8.0-41 update if your console is hacked, at least until there's a fix.
If you have knowledge with compiling files, you can apply the fix, but for the entry level user, it's advised you wait.
- Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience
