Hi everybody, first i'd like to apologize for my ugly english... frome several months i tried to update my son's 3ds to get the profile exploit in 4.5 but i encountered a lot of problems... sysnand is actually 8.1.019E and was updated from a cartridge update ( maybe fantasy life ) wich is not like an e-shop update. The result is that some files are missing and i'm not able to downgrade from 8.1 to 4.5 because gateway downgrader doesn't let me do so. I got an error everytime i try the process. I need a way to update our sysnand from 8.1 to 9.2 and then downgrade properly via gateway. The problem is that Sysupdater doesn't launch in Sysnand. So is there another way to install cia's from 8.1. Thank you very much for your help.
