When I originally did this I did 'launch Dop-Mii (You have to put Dop-Mii on your apps folder on your sd card). Then press a to continue. Dan you have to stand on IOS: 36 and press a. Then you have to press A on IOS, BC, HIOS. Then you have to go to IOS 56. And do the newest version. Then press + to patch the IOS.'
(Edit: I was getting an error, but I guess the shop channel was down!)
On a side note, do I just have to install the d2x? Or do I have to load it and make sure it's running off that one? I'm new to softmodding, and wasn't quite clear how it worked. If it loaded the correct one automatically after install, or we have to. Thanks for the patience.
