I had version 2.00 on my psp but decided to downgrade to 1.50. I deleted everything on my psp and tried to start the downgrade process. After i turned on the PSP after the watching the .tif file I didnt get the downgrader up under games/memorycard on my PSP on the main menu. I know I have added it in the right folder. One thing I do remember is that I had a version changer on my PSP v.2.00 and I have set it to 1.00 before I deleted every homebrew games from fanjita. When I checked the version now it says 1.00. But I have the browser and that works.
Please tell me what to do!
