I had the same issue (I am JP - my email was in the DCRainmaker post), and was forced to regress to firmware 2.8 as well. Seems as if this is not something they are likely to address anytime soon, either (which is unfortunate.)
Here is the download link I was provided to get the appropriate firmware:

Still have issues with it not keeping a steady cadence number, but no-where near the problems I had before.
