You don't necessarily need Kernel9LoaderHax to use my stage2 launchers. Luma3DS and CakesFW have TWL_FIRM patching now and they have menuhax compatible payloads now? I've used Kernel9LoaderHax for so long that I forgot now. But I'm pretty sure they do. Don't use rxTools though. That thing is ancient and out of date and is missing the last of the TWL_FIRM patches needed for this stuff to work.
If not using Kernel9LoaderHax, you need a console with sysnand on 9.2 or less to use CFW. The new 11.x browser hax WILL NOT WORK for this!
