Today I was installing the m33 prometheus-4 onto my PSP 1000 so I could run Monster Hunter Portable 3rd with iso_tools, but instead I installed prometheus-4 auto-cfw and now nothing will load on my memory stick. I can't even load the UMD in my psp. I was able to load the m33 updater but it wouldn't change my firmware. How can I remove it and do a fresh install of m33? Going into the recovery menu and trying to recover from there also hangs. I have also changed the umd driver to sony but that doesn't help. The system info when I go to it says it's on 5.00Prm-4at.
