Thank you for your reply. To answer your questions: - Yes, I am unzipping the image that was loaded prior to putting it on sdcard - Nothing else is plugged in. Only SDcard and 5V brick are plugged in - The brick is rated at 5V, 2Amps - I have formatted the SDcard but not consistently. I will try again.
Note: The SDcard I am using is a SanDisk 8 GB class 4 card. It has been used successfully to re-flash (un-brick) a different BBB, although I am using a different image.
