Hi zero_cool, I hope you might be able to steer me in the right direction. I have successfully downgraded and installed m33 CFW on 2 Fat PSP's and 2 PSP 2000, however I just purchased a UK PSP 3003 and find that my Pandora battery & Magic mem stick do not work. PSP wont go into service mode and data on mem stick shows as corrupted..... then it just turns itself off..... The new PSP 3003 has Official FW 5.05. Is there currently any way to hack this and install CFW on the new PSP. Any help with this problem would be greatly appreciated. Thanks in advance, AntonJack
