1. You need Devmenu to install the Mset.cia
2. Pasta boots you into sysnand with signatures patched (You need this to be able to install unlegit stuff to the Sysnand with FBI) - Reinand doesn't have an option to turn off firmlaunch atm as far as i'm aware.
3. You want to install the Mset to the Sysnand, not the emunand
4. Dunno
5. Yes
6. Once everything is done. You can remove the mSD > Format the Sysnand > Go through the setup process > Reinsert emunand. - you'll need to reinstall the ROP to sysnand.
1. well FBI is probably the best cia manager (imo), BUT, its a tad on the "advanced" side and gives users the ability to delete system titles etc, so seeing as this is a noob friendly guide its best not to have newbies messing with tools that could potentially brick their system if the mess about with it....that and dev menu cannot be launched via ninjhax, so we need to get devmenu installed with a ninjhax compatible cia installer, and even more, FBI has a handy MSET profile installer so it serves 3 purposes having FBI in there, but keeping dev menu as the final cia installer makes it safer for newbies, if they feel like playing with FBI instead they can find it and install it themselves, but this guide was just to give people what they need to get up and running
So is Devmenu literally required to downgrade MSET, or is it used just for the purpose of making this guide "newb-friendly?" Doesn't ReiNand permit the installation of unsigned CIAs as well? Why is firmlaunch a bad thing? If our objective is to downgrade MSET on the sysNAND, why do we bother injecting it's backup into emuNAND in step 3 in the first place?
