I know you all just threw up in your mouths a little from reading the title of this thread but sadly yes I do need some help Unjailbreaking my PS3. The reason for doing so is my own. I have done a full format, attempted to install the latest patch from PlayStation but I either get a "data corrupted" from doing an update via storage device or no applicable data found when doing it in safe mode. It wont let me update via network and I followed many of the instructions that i found on another thread but unfortunately I came up empty. I have used multiple USB devices and all were formatted correctly. Please help if you have any ideas i could try.
