I have it mostly disassembled (and the battery unplugged), but it won't detach. It seems to be a problem with the area around the top strip of the back of the ereader, in the panel where the power button is.
Can anyone who has disassembled one of these before give me a pointer on how to completely open it up?
Here are some photos for clarification.
