I already had the 1.7 firmware on it..
Even so, I formatted the miniSD card and only put the 1.7 firmware on it..
I don't understand "# 4. Open the DS power switch, don't care about the screen and wait 5 seconds." Do you mean turn on the DS and wait until the Supercard screen is up (with list/save/cheat/etc at the top)? I still have the Superkey in to bypass the health warning and boot screen..
So far, pressing A at any time has not done anything.. I'm not sure if I'm doing it wrong, or that it won't work since I already have 1.7 firmware installed..
Frustrating..
