I've got an R4i 3DS card (R4I-SDHC.com). It works fine but I'm thinking of doing a system update so I can use the browser and possibly download the free Zelda 4 swords game. I have never done a system update, on the system settings page it says Ver. 1.0.0-0E. I'm worried about blocking the R4 card. This is what I plan to do, I just want to know if it's safe: Upgrade my firmware to the latest - "R4i-3DS V1.46b English" through the 3DS R4 upgrade and then performing a system update. Would this be ok to do?
