Tutorial Installing Dev Firmware and Dev Apps on Retail 3DS

[Duckling]

There is literally a option called "Dev. features"

Yes I figured that out however I am unsure which I am supposed to check off as in the Dev. features.

Your Luma3DS (DEV) Link is dead seemes the uploader deleted that pathway. Any other dev Lumas?

Thanks for the heads up. Fixed.

So... I think creating a EmuNAND on my New3DS with Luma9.0 + UNITINFO + SD SystemUpdater for SNAKE (N3DS Dev Firmware / 598MB) wouldn't work, huh?
Have not tried it yet.

i found a software named firmtool that could allow to convert an a9lh binary to a firm file, i'm trying to look at it

 

[Pikachuk]

hmm just tried it i got a black screen after converting it to .firm so it doesn't seem to work well with b9s

is there an easy way to go back to a9lh in this case ?

No, you dont need to change to a9lh, I'll upload an AIO pack in a minute.

One question, do you want to boot it by holding a key or boot it automaticlly instead of Luma3DS?

hmmm since it's for a dev firmware it would be on emunand so with a key (l key for instance)
actually i've fastboot3ds installed so it makes it easy

Ok, so when I upload the pack assign the file called BootCTR9.firm to a boot slot and confogure the keycombo as L.

Extract this to the root of your SD Card, then assign it to a bootslot and set the keycombo as L:
