1.Find the package from that ISO site. Pick right region if you wish.
Easily you could find 0004013800000102.cia in the package. or simply TWL_NAND.
2.Get PastaMode/DevMode or other no-firmlaunch enviorment.
In case you don't get bricked. Yes braves can do with firmlaunch, and TWL_NAND doesn't get involved in FIRM0/FIRM1.
3.Install FBI. Then launch it, press L to make NAND as destination while you are in SysNAND.
Do not install NATIVE_FIRM/TWL_FIRM/AGB_FIRM to SD, as you shouldn't install SD applications to NAND.
4.Use FBI to install that title CIA. You can see that is "Install CIA" as default if haven't pressed R.
5.Then just try it. Tada/profit.
