Hi, I am trying to downgrade a psp slim using the easy installer. I am having issues with the software. The issue I am having is that it is notbring up the ABS sector Y/N option at the end of the installation, hence not finishing the install. The computer is running XP and I am using a 1gb sandisk. I have used this same installation process on my own psp with the same computer and memory stick. I have followed the guide numerous times, step by step, but no success. Someone please help, I am at a loss. Thanks
