That is Luma 10. I thought as much when you mentioned having replaced the file in your original post of this thread.
This makes me wonder. Does the sd card has to be a particular kind of sd card? Ik there is like multiple kinds of sd cards
Worked before adding files to SD, tried changing boot.firm…
============
If it worked before removing the SD, you had at least Luma v9.1. For whatever reason (contact issues, dying SD, file system corruption…) boot.firm is not found on SD and B9S falls back to the (outdated) copy on CTRNAND.
The fastest thing you can do is trying another FAT32 formatted SD with only Luma3DS boot.firm (v9.1 or v10.0.1) on it to see if the console boots with that.
I recommend checking the SD(s) in question for defects and fake:
- Copy all your data from the SD to a computer. Reformat the SD to FAT32, 32kb cluster size, if bigger than 32GB and using Windows with guiformat.
- Check your SD Windows, Linux, OS X.
- If you get any errors replace the SD.
- If you get no errors copy your files back on the SD and try again.
