My Phantom no longer powers up

    I have not used my Phantom 2V+ for about a year. The batteries were stored outside of the phantom in a safe place. They were about 50%. The Phantom will no longer power up. When I hold the battery button, the 4 green lights illuminate along with the red one on the power button. Nothing happens. After a while, the red power button light starts to blink.

    Any Suggestions?

    1. You can damage (even permanently) your batteries if you tend to re-charge them while they are hot. Let them cool to room temperature first.
    2. Just as in the old computer days, nothing beats "rebooting," which in the case of the Phantom 2 and 3 translates to uninstalling and re-installing the APP.
    3. When you re-install, most cell phones/tablets/etc. require that you enable certain DEBUGGING procedures. To do this, access your cell phone/table SETTINGS and look for DEBUGGING options.
    4. As all cell phones/tablets/etc. are different, finding where to DEBUG will be different for each. In Google Nexus 9 it is done by clicking on DEVELOPER OPTIONS and then enabling two items therein: USB DEBUGGING and VERIFY APPS OVER USB. Until and unless you enable these two guys, you will not be able to connect to the DJI APP. Hope this helps.

    ??? This problem is with my dji Phantom 2 +, not my cell phone or tablet.

    Mikey, please LISTEN. I didn't say for sure this problem was with your
    cell phone or your tablet or other device. What I said was, in summary:

    1. It COULD be your cell phone or tablet. How? Well for one, if you have
    recently updated the Phantom FIRMWARE it will likely have new settings and
    commands that your cell phone/tablet refuse to support until you enable your
    device's DEBUGGING ability. That's to protect you and your cell phone/tablet,
    whose manufacturer could care less about your DJI Phantom. Your manufacture's
    duty is to protect your cell phone/tablet, not your DJI Phantom.

    2. In the case of the Phantom 3 (P3), which I happen to own, there is a
    glitch in the APP that suddenly causes it to "DISCONNECT". The craft will still
    obey commands and fly as though nothing is wrong, but it's uncomfortable
    because you don't know a) why this is happening and b) if it will continue to
    fly as it should or suddenly crash as a result of being "DISCONNECTED".

    The remedy for this is to:
    a. Uninstall the APP
    b. Re-install the APP
    c. Turn on the Remote Control (press once to turn on, and quickly again and hold until the Remote Control lights come on)
    d. Turn on the Craft (press once to turn on, and quickly again and hold until the craft's lights come on)
    e. Open your cell phone/tablet SETTINGS, find something called
    DEVELOPER OPTIONS (or similar) and enable USB DEBUGGING.
    Also enable VERIFY APPS OVER USB. This same wording won't
    appear in all cell phones/tablets the same, but the gist is that until
    you enable DEBUGGING some cell phones/tablets will NOT allow your
    device to communicate with the DJI APP. Moreover, I am having
    to re-install the software and go through the entire setup every single
    time I fly the craft in a new location. Don't know if this is a glitch in the
    APP or my Google Nexus 9.

    All or none of the above may work for you. I'm just sharing with you what
    worked for me. If you haven't tried the above, why not at least try it. If it
    works, let everyone know and if it doesn't, let forum members know that
    as well.

    As stated, I use a Google Nexus 9. The above works in my case. It may not
    work in all cases. But if you want to HELP people, try the various
    remedies that people take the TIME and ENERGY to share here with you,
    for free, and then report your results. That way you help too.

    One short push shows charge level, one long push, the battery status. To power up, you should press the button twice, one short, then one longer, until power up.

    All DJI buttons require that you press them twice, as follows:
    + Once to turn on and then quickly
    + Again and hold down....until the lights come on.

    Thanks everyone for the help. It is over a year since I turned it on and forgot about the double press. It is amazing what I forget in a year. :)
