Hi, I Have a Ta 088 V1/V2 PSP Motherboard and I have accidentally used the flasher on the custom firmware pro B10 6.60 and am having trouble getting rid of it. I want to get it back to official firmware, how do I do that? I have tried uninstalling it using the triangle method in recovery mode but that semi bricked my PSP. When I put ofw 6.60 in the update folder and tried to run it, I get the message 6.60 is already installed. Any help will be appreciated.
