monster9,

You have a version of the jetBook firmware that is not yet publicly available. My guess is that if it includes the eReader DRM support, they added some checks that keep it from being cross-flashable, similar to the problems with cross-flashing the jetBook with Aluratek firmware. For example, after the Aluratek Libre added ADE DRM support, you would not be (easily) able to flash back to an earlier version. If it is as you say -- you cannot flash to 0.33g or 0.33h -- I don't know what to tell you until ECTACO releases 0.34c and we can dissect it.

One other thing you might try is running Reflash NOR in the self-test menu with the 0.33h firmware unzipped to the jetBook/SD prior to downgrading to 0.33h. Worth a shot.
