i hadnt turned my op-z on for a while and went to update the firmware today. that worked well. however, the unit wont power on unless i have it connected to a battery or the computer. i tried resetting the factory settings, taking the battery out for a while, different cables, nothing. the battery meter is full solid green and the ios app shows 100%.
any ideas? could the battery just be defective? not sure what else to try. it works totally normally when plugged in.
