Okay, I'll admit it. I kinda rushed trying to install 5.50 GEN-D3, and selected "Flash 5.50 OFW" instead of installing the CFW itself. I assumed that I had to have the OFW before installing the CFW. Of course, as you probably all know, I was dead wrong. Now, to ask: is having a Pandora battery and a Magic Memory Stick the absolute only way to downgrade my PSP? If the answer is yes, then here's another question: does using a Pandora battery mean that it will go into service mode every time I turn the PSP on? Because I only have one battery to work with. If the answer is no, then please elaborate. Thank you to all who answer.
