I just want to update this card but it seems like i cant it, it says in the first screen (the screen you see when you boot up my r4) it says its updated to 1.70b but when i go to upgrade its on 1.43 and 3DS 3.0 and not only that but the upgrade button never appears. Is there any way you guys could help me with this? Ive been trying to fix this for three days now -_- i feel like you guys are the only ones that can help. heres pics
