Have you already tried with the flashall method with the latest image? In case you haven’t, I suggest you to follow the steps suggested in this message, but use the latest Edison complete image which can be downloaded from here. In that same post there is a suggestion to run flashall.sh --recovery first, please try that as well. In case neither of these suggestions work, please fill out this form so we can take a deeper look into this.
You are correct, the problem was that some features of configure_edison are not available in some of the older stock images. The solution is to update the Edison image with the current flash and then try to configure.
Thank you for your help
