    ocnbrze DON'T PANIC!!!!!!!!!

    what tablet do you have? most likely the update closed up the dev option. was it there before the update? and it was enabled?

    curious, can you post a screen shot when you try to run adb commands?

    Given that this is a secure tablet designed for use in prisons, running a rather customised Android version, that's very likely why there's no Developer Mode in it. ADB may have been disabled/removed by the Jpay update, to increase security against unauthorized modifications?
