I got the same problem as you today.
If you have a custom theme, just remove it.
That instantly fixed the issue on my Gateway cart.
I believe it has something to do with Badge Arcade, since I downloaded it after the update and messed with it.
Right now, I have a R4i Gold 3DS game cart with that quiz game and my firmware on my 3DS is 4.5.0-10.
So, my question is, can I update my cart up to the latest update (6.1.0-12) through the instructions found on the first post?
I am a bit worried since I am not sure what the official site...
One of the sites that weren't blocked on the school's network was some file uploading sites. I would upload some games, write down the URL and take it to school one day.
my school has a chrome extension called light speed filter agent and it legit blocks YouTube pfps since the file cdn(I think aka yt3.ggpht.com) is classed as mature
It was easy to bypass some of the restrictions, as one of the admins left a registry key in the administrative shares drive, which allowed me to get around the blocking of some sites.
