Place Luma3DS 9.1 on your SD and try the following troubleshooting steps if you didn't already https://3ds.hacks.guide/troubleshooting#black-screen-on-sysnand-boot-after-installing-boot9strapPlease help!
I am new to CFW. I have been following the 3ds hacks guide provided by Plailect. And I got stuck in the finalizing steps when I couldn’t get the Homebrew launcher to work. I found out that it wouldn’t work because I’m using Luma 7.1 and I need 8.0 or higher. I tried using the latest release of Luma3DS but for some reason I could only get the boot.firm for luma 7.1 to work. Any other version and my DS wouldn’t start up just a black screen.
I am using a:
Nintendo 3ds(old version)
r4i sdhc flashcart
Boot9strap 1.3
Luma3DS 7.1
When I started the process my DS was 11.6 but the finalizing process said to update so now it is 11.8.
Thank you in advance.
Make sure to boot without your flashcard inside the 3DS
