I have patched IOS36 and HBC ended up upside down but re-installing Homebrew channel sorted this out. I have since loaded preloader v0.29 and run into problems. Preloader loads and I get the menu (systememnu, homebrew channel etc) but this is as far as it goes. i cannot load homebrew or systemmenu. If i try to load systemmenu it says there is 'the sytem files are corrupted....'. On the preloader screen it says there is an important update to v0.30. Should i try to install that next? Any help is greatly appreciated. I assume it is something to do with running preloader on a 3.4e system.
