My N3DS (9.2.0.0E) was basically brand new. I had only tried out the new display tech with some of my ~20 physical games before putting it back in it's box, because I didn't want to transfer my saves/files over from my older 3DS XL.
I followed the quide from start to finish within about 2 days. I found this thread when I had to do a Google search because I couldn't find said files anywhere on my SD card. Since I was 100% sure that I followed all the steps exactly as they were explained and since I had multiple NAND backups in multiple places, I decided to continue without said files and everything works just fine.
However, I ran into three other problems:
- Browserhax didn't work. I ended up using Cubic Ninja, instead.
- Had to use an older version of menuhax. 2.1, I think. The latest version didn't work.
- The latest version of OTPHelper didn't work even after ~17 reboots. Ended up using an older version.
