As stated in the other thread, don't buy a sky3ds+, it's expensive and you have a chance of install arm9loaderhax, which is the perfect hack and gives you endless possibilities of piracy and homebrew.
Sky3ds+ should only be considered in situations that you're
stuck on 11.0 and don't really have a chance of downgrading (which you have because you are on a hackable 4.5 firmware and can follow the guide to upgrade to 9.2 and thus carry on with the cfw and a9lh process) which makes the money a waste.
Alao, it's pretty unsafe to use a sky3ds without private headers and kind of tricky to inject them which makes using it online a risk.
And it's not convenient for even piracy overall.
My recommendation to you would be finishing updating to 9.2 and from there just setup emunand, menuhax , update emunand, and use luma3ds cfw, and stay there, if you don't want a9lh.
Anyways, it's your choice.
Just saying that getting cfw is faster and cheaper and certainly easier than paying 80/90$ for a stupid flashcard and waiting x weeks just to be banned when playing online.
But it's your choice.
Anyways, on topic:
