fmtool error

Hello, I am trying to run osmocom on Motorola C117. Using the following : PC(Ubuntu12 64bit)<---->USB To Serial cable (5v)<---->serial to (3.3V)<---->phone when i press power button all i can get is "fmtoolerror" . and there is no more messages only that . I am wounding if that means the phone is not working properly or it could be a cable issue ? Thanks very much .
