I followed this guide to install BootMii and HBC with LetterBomb And later it told me to fomat my SD card. After that I tried booting BootMii via HBC I just got a black screen. I thought I did something wrong and uninstalled HBC. Now I'm retrying to install HBC via LetterBomb, except it doesn't recognize it anymore. (I don't see a Letterbomb in the mail section.)by tunaspirit - Getting Started
