With putty, did you set flow control to 'None'?

What flash size has your module? The ESP01 boards used to have 512kByte Flash. For those you have to use that specific firmware image form the daily builds.

You may try other -fm options when uploading the firmware. The default is -fm dio. Sometimes -fm dout works. But for my ESP-01 I used the default mode.
