What I'm trying to do is create a Magic Memory Stick for MY PSP 1001, which I bricked with a partial flash of official firmware 1.50 with Hellcat's Recovery Flasher, which I ran from 6.60 ME 1.8. Now, I've already tried three memory sticks, all of which I own, one being the newest Sony 8GB Memory Stick PRO HG Duo HX with Magic Gate, one being a standard Sony 4GB Memory Stick PRO Duo Mark2 with Magic Gate, and the last being a standard Sony 8GB Memory Stick PRO Duo Mark2 with Magic Gate also. None of them have worked for me. What is wrong? I've tried all sorts of MMS maker programs, including PSP Grader, but mainly focusing on re-usage of Rain's Ultra Lite MMS. Let me simplify a list of problems I am having with each memory stick, in different situations. I want this to be as easy to read as possible. Sony 8GB Memory Stick PRO HG Duo HX with Magic Gate - It seems to work fine in Rain's Ultra Lite MMS program, but the main problem I am having with this stick is that it just won't do anything when I put my Retail Pandora Battery in my PSP and insert the stick, holding the L-Trigger. I am supposing this may be for two reasons: 1. The storage size is too big (MAH SPOON IS TOO BIG!) or 2. It is one of the newer 8GB memory stick models, being an HG Duo instead of a PRO Duo with Mark2. Thus I suppose it is unsupported if being used as a Magic Memory Stick anyways. 4GB Memory Stick PRO Duo Mark2 with Magic Gate - Now this memory stick is not as big as the 8GB's, so I would assume it to work flawlessly as an MMS (Magic Memory Stick), but apparently I was wrong. I used Rain's Ultra Lite MMS, with the format option checked, and everything appeared to install the way it should. But again I am getting no menu on my PSP when I put my Pandora Battery in and insert the MMS with the L Trigger held down... I tried it the other way also, inserting the stick and then my battery, but ALL I get EITHER way is a green light. No downgrade menu at all. This has me SUPER puzzled, as this should be working, yet it isn't. It also has me super frustrated, but, on with the story. Sony 8GB Memory Stick PRO Duo Mark2 with Magic Gate - This particular memory stick, ironically, has given more problem than the others. Though it is a standard stick, I have trouble getting the TM IPL to inject when using Rain's Ultra Lite MMS Maker, unless I inject the IPL FIRST with "Inject TM IPL Only" and then click "Make MSS". After Rain's finished its work, I again put this stick in my PSP, then put in my battery, holding down the L trigger. Still NO RESULTS! All of these memory sticks have been formatted with Windows XP Professional, Service Pack 3. My PSP is black-screening, so I cannot format my memory sticks with my PSP as I need to do. I also have a pseudo error when I try to format ANY of these sticks with mspformat.exe. I also have another question. Does it matter which size memory stick I use for my PSP MMS? Does it have to be a 1GB or 2GB? I remember using a 2GB Sony standard before, which is now conveniently broken. Does the size matter? Seems it wouldn't... So, I guess this just leaves me to ask... What do I do now? Any help is appreciated! Thanks.
