thanks, there were like 2 titles that it didnt install
I ran into an incomplete downgrade on my n3ds as well.....
It displayed as 9.2 in syssettings but CFW would not boot
They call this frankenfirmware or something like that.
I fixed it like this:
1. Used a Super Smash Bros game cart to update to 9.5 (i think xenoblade will work as well)
2. Downgraded again using
This SysUpdater
Just make sure the cart you use will put you on 9.5 or firmware that is higher than 9.2 but still has hax easily available on it.
I am now on legit 9.2 and running CFW just fine.
