Installation of the USB2.0 cIOS with/without Wifi
You need to install the USB 2.0 cIOS from here (Please note that this requires a internet connection).
There is a offline instalation available, to read the guide, visit: here
The installer is for Homebrew USB2 only, this will install IOS202 using base IOS60 and IOS36 automatically. You can select the IOS to use to do the installation, so you can select a IOS with the fake sign bug. watch it download, install incase it fails and returns to HBC, it should now install successfully. (IOS60 and IOS36 are downloaded to SD via the Nintendo's Update Server).
We are using IOS60 as a base as there has been improvements in wifi. Those that install this cIOS do not require a DVDx instalation.
Users without the fakesign bug cannot install the cIOS to use USB2: There is a work around for this but requires you to downgrade a certain IOS, to be able to place trucha into another.
Trucha Bug Restorer is an application in which to get IOS with the trucha bug back on all Wiis (and new) with system menu up to 4.1. Usually the error codes -1017 and -2011 indicate that the trucha bug is required and missing.
Make sure you understand what you are doing before using this. Only use it if you have an idea what the trucha bug is and why you need it.
