I can't launch the homebrew launcher.

Replace your boot.3dsx file with the one in with 10.2.1?

 

Perform (again) this guide (at least, the section III):

https://3ds.hacks.guide/finalizing-setup.html

Or if you have FBI working, then install the Homebrew Launcher (Dummy) Wrapper and try to open the Homebrew Launcher through that app.

 

having the same issue

didn't work

 

Why exactly? Any particular error or difficulty is happening?

And what's your actual hacking set (I mean, B9S and/or Luma version, and actual system firmware)?

 

you need to add rosalina when the download play app starts, not when it shows the splash screen.

 

Latest luma, latest fw. If i try to use the app you linked, i get the screen "if you are seeing this luma3ds is not configured to load the homebrew launcher" and If i do what it asks (same steps to make Download Play the HB launcher i just get the same screen. And if i do it on Download Play same thing as the op, nothing happens.

 

Weird... Are you able to open the Rosalina Menu at least? And you have the latest version of Homebrew Menu (the boot.3dsx file) on the root of the SD card?

Are you using GW or EmuNand perharps?

 

Yes, I'm able to open rosalina menu and do the steps it asks me. If I hold Select on boot, yes the menu does appear. No, i'm not using GW or EmuNand.

 

The only explanation to this behaviour is that Luma config.bin wasn't storing changes made on Rosalina Menu (perharps because a kind problem with the SD card, like corrupted files?...). Could you delete that file from the SD card if exists (onto the "luma" folder) and try again?

On the other hand, when you access to the Luma config menu (pressing SELECT on boot), what exactly does it say in the yellow text on the bottom screen? Just for check
