Hacking Unsupported launcher (argc = 0)

[Tocamos]

Hello! First of all, apologies for my English, I'm using a translator.

• Explanation fast: My 2DS has the error of the title.
• Long explanation:

I was banished by the wave a few days ago. Following a guide I changed my localfriendcode_b but from there my console did not turn on (the screen remained in black and the blue led)
Looking for solutions I decided to upgrade to Luma 8.0 and boos9trap 1.2 however, still did not work.
Finally I followed another guide that made me change the "boot" file, but it did not work either.
And, the strawberry of the dessert I followed the instructions of a comment that said that it removes the folder LUMA and boos9trap and that puts new ones. Result: The error.



Does this have any solution? If so, how do I fix it? Keep in mind that in addition to being an imbecile I'm not very aware of this of hacking nintendo 2DS

That error means you are on boot9strap 1.2 but are trying to boot Luma 7.1, not Luma 8.0. Download the latest Luma and put its boot.firm on your SD card/CTRNAND: https://github.com/AuroraWright/Luma3DS/releases

Oh my god, I think I love you. The error no longer appears but the screens still do not light.
Solution?
