Yeah, I read about that earlier and considered it but I read somewhere that there's a chance that the console may be bricked. Since I'm just going to use my 2ds for pokemon cloning and the like, I'm not open to such risk however minimal.Don't update to 9.4! Update to 9.2 and use CFW. You can update by software, see https://github.com/Plailect/Guide/wiki/9.2.0-Update
And that is why I intend to go the safe route which is updating through cartridges. Any idea as whether all Codename STEAM cartridges update the firmware to 9.4?
