Ok, so I'm planning to write a full updated guide to cfw soon (don't worry, you have plenty of good tutorials so it won't be posted here!) with gets to every corner of the scene, not just installation. I'm having trouble finding how one should downgrade mset on 5.X,7.X and 8.X o3ds/2ds. My idea was to get some no-firmlaunch cfw to run through mset (mainly rx devmode) and sysupdate to 9.2 asap, but for that I need mset downgrade. Good point is they all are running spider, so I think GW Launcher MSET downgrade could be a choice, but 2ds systems will not survive a system format in 4.XDG mset and I don't know for sure what it does to the system. Second idea was cart update to 6.X if lower, but there's the need of the cart. At the end of the way is also that 8.1J browserless system. Yikes. Any tips?
