Hello - I'm running 4.2 system menu. I've followed the guide up to this step (http://sites.google.com/site/completesg/hacking-guide/trucha) And then I wanted to install this: http://sites.google.com/site/completesg/cios/waninkoko I've downloaded the appropriate IOS38-64-v3867.wad, and it is placed on the SD card. Not sure what this means in the instructions [If this is your first cIOS, choose 36. Else, choose 249. (If you have problems with this, go to the Trucha Bug section)] but I chose ISO36. And the error message it returns while reading the WAD is error ret = -1. I'm not sure what this means, and I'm unsure how to know what cIOS I have installed. I also saw this article - http://gbatemp.net/t212497-best-cios-selection-for-newbies - should I follow this one instead? Thanks.
