Well, i already downgraded three o3ds , but this is the first time i will do the oposite, and to be honest i'm more scared now than when i needed to downgrade. I will receive one o3ds with sysNAND < 9.2 and i want to install rxTools and "do the cooldboot stuff " to start on emuNAND, so i need the 9.2FW. I read some topics and tutorials, and already asked some questions, but as i say, i'm a bit (a lot) scared to do this. So i need "a recap". If i get it right, this is what i need to do and the the order i need to do: 1 - Install emuNAND (can do this with gateway) 2 - Install rxTools 3 - Install sysUpdater .cia in sysNAND (Can i do this with gateway sysnand mode? using fbi.3dsx) 4 - Run rxTools DevMode to use sysUpdater 5 - Update the sysNAND to 9.2 using sysUpdater (ofcourse, after i placed the .cia files in updates folder) Thats right? Did i forgot something or i'm wrong in any step? That is the tutorial i will be following: https://gbatemp.net/threads/how-to-upgrade-your-old3ds-from-4-1-8-1-to-9-2-0-20.389187/ Thanks!
