I recently decided to install HiyaCFW+Unlaunch with the help of dsi.cfw.guide, but I ran into a problem while trying to backup my NAND. The problem in question is that I only ever get two white screens, after trying five times to launch HBMenu, and following the guide step-by-step. I've formatted my (2GB) SD card, Replaced the files before and after formatting it, but to no avail. Do any of you people know if there's anyway I can fix this?
