Hi,
I was working on this this morning concerning the same problem. So far I have made it all the way in with minimal damage... but I did some minor damage I will have to go get fixed. Anyways to open the zen micro,
1) Take the battery out
2) Move the metal plate behing the player towards the back
3) Where you plug you USB and Headphones, with a small srewdriver you can pop the from mini rubber plate... You should see two small srews to be removed.
4) Only then can you push from the back (on metal plate on battery) and take the hardware out of the casing, try to keep it as staight as you can, do not take the hardware out on a angle.. this could be dangerous.....
if you have questions email me
