Flashing problem

Hi, I have a problem trying to flash a 3310.I am using rolis,I have not had problem before.Iam loading the same as usual and i have tried on a phone which is working fine and i am getting an error message saying;power off mobile first & then connect (or check cable:phone tx=low (o)expected but phone tx=high read)I have tried with and without connecting to the phone & i am still getting the same message.
Have i a problem with rolis prggie; or cable?
Regards.
Rob

I think it is a cable problem but try again..restart your PC and if using winxp try to use userports

Hi Romeo 26222,I have now found the problem.I found a split in the cable.I have now repaired it,and away we go!!!
Thanks for your reply.
All the best.
