I've been trying all evening (its now morning) and I havent even managed to launch Homebrew browser yet.
I'm running 9.9.0.26U on Zelda MM gold edition N3DS, followed the instructions for tubehax to the letter, tried all the various 3dsx versions people have used and stated it worked for them, but its clearly not working for me. (I'm no noob to Wii/vWii/PS2/PS3/Xbox/360/PSP & vita hacking so.....)
I have deleted and tried again more times than I can remember.
The only thing I havent tested is using an alternate wifi connection: could this be the cause?
(edit: I have a Virgin super hub 2)
