Allright guys I'm back and now I'm confused? How exactly do you use the dual boot feature on the E3 flasher? I have 4.00 OFW on my current slim 160GB PS3 that I bought to replace my broken Fat. I understand how to install the Flasher, that's easy. But the dual booting feature they added will be confusing, but that will be exactly what I'll need to get back to my beloved custom firmware I once had!

Thanks guys!
