i put the files on the SD card and ran the install and its just sitting at the screen that says "THIS SOFTWARE MUST NOT BE SOLD" in 2 paragraphs about selling it and just sits there. is this normal? it's been there for about 10 minutes
modmii isn't the problem. any other guide will supply the same files....
the exploit isn't the problem either since you got beyond that to the hackmii installer scam screen. ...so the twilight hack (or any other exploit) won't help. not to mention: the Twilight hack has been dead since SM3.4 anyhow.
so that leaves the hackmii installer itself. you can try getting another hackmii boot.elf file assuming there's something wrong with the one you have (a long shot). the scam screen does have a timer before allowing you to press '1' on the controller....like 20 to 30 seconds or so....which can feel like the 10 minutes you talk about above. so if the 10 minutes was possibly a 9:45 exaggeration, you can try it again....
honestly though, i think your best (only?) option is to try another card. issues with micro card adapters are nothing new....
My apologies, now that I know your system version I understand your problem. The newest HackMii installer DOES infact get stuck on the screen you mention when below v3.4
In anycase, could you please provide me with the following information?
-What region is your Wii? [In System Settings it'll say your firmware 3.2(#) and a letter next to the 3.2 where I put the (#)]
-Is your Wii connected to the Internet?
If your region is U,E, or J and it IS connected to the Internet I would recommend doing an official update to v4.3
Normally I would be against this, however in your current situation I would highly recommend it. After words, you will be able to use the LetterBomb exploit.
After you hack your Wii you can downgrade to v4.1 (The best system menu without the anti-homebrew measures)
