I have a PS3 set up with the lastest REBUG on 4.82. How do I prepare to use OtherOS? I just get an OtherOS: Operation Failed. I know I need to prepare it somehow but don't know how. I found this: https://rebug.me/boot-otheros-otheros-prep-tool/ but it's from 2011. I haven't done anything in the PS3 scene til now so I'm OOTL on this stuff. Thanks.
