Planner not letting me change Firmware

I recently tried to change the firmware for my impee and it seems to not “stick.” I don’t see my Imp change from flashing green and it is still running the same firmware.  Anyone else seeing this?

Ok, this seems to happen if there is an error in my code (although it is so hard to tell where). I commented out most of my code, and it let me switch easily.

We are planning on implementing a more elegant method for handling these types of errors in the future.  For now, if you encounter a similar error, we recommend that you (1) run one of the example codes and if problem persists (2) check the power.  If you continue to have the same problem after trying these, then let us know as it may be an imp or planner issue.
