Hi again guys. It's desperattion stage now!
I have tried to flash using the Odin link above and all seemed to be going well... Until it got near completion and there was a message in Odin along the lines of 'Cannot find pit file or partition'. Then FAIL! Any thoughts on how to proceed? Or a way around this issue? Any other methods I can try? Basically, anything that will stop me putting a gun to my head and just ending the torment!
Thanks again for all of your help and advice.
