Hacking Flashcart setup failed

[deadnuggets]

I have a R4 SDHC Dual-Core 2021 and I tried to install ntrboot and go to the R4iSDHC Family and press A it freezes and remains that way I followed the 3ds hacks guide and I saw that they mention that the flashcart has to be 2014-2020, and maybe that's the problem, but is there any way to do this with a 2021 flashcart?

When the guide says it works only with 2014-2020 cards, you are out of luck.
