If anyone can offer even a nugget of assistance, I'd be eternally grateful. I'm trying my best to figure out how to get this thing to 4.5 but I can't even access the gateway website from my 3DS properly. Everytime I input the url and press the L button when the bottom screen turns white, it just stays at the "loading Gateway 3ds..." black screen of death. I can't figure it out. I think the first step is to downgrade but then I still need to get into this website, back up Nand and then downgrade before I start playing games offline. Please help. What am I doing wrong? For the life of me I can't even find the answers online.
