I said it does it automatically only with v.11 and onwards (not with older versions).
Same.
Did you miss the part where I said I upgraded back to 12 and it still didn’t copy? Or did you just leave that out because it doesn’t fit the narrative you’re trying to say?
Here, I’ll outline the steps performed so you can try it too.
1. Remove Luma3DS boot.firm file from NAND using GM9
2. Downgrade Luma3DS to 10.3
3. Boot.
4. Power off.
5. Upgrade Luma3DS to 12.0
6. Boot.
7. Power off.
8. Remove SD card.
9. Attempt to boot. It will not.
10. Replace SD card.
11. Fire up GM9, use scripts to copy Luma to NAND.
12. Power off.
13. Remove SD card.
14. Boot. It boots.
Edit: formatting. Also, I can try this with Luma3DS v11 if you’d like as well, just for posterity?
Second edit: I’m receiving two unmodified 3DS’s today, in fact. One is a n3DS and the other is an o3DS XL. I’ll be sure to try this on them as well with Luma3DS v11 and outline my findings.
