Just bought a brand new Spark but after installing the latest FW is gave an error "Aircraft Locked". I even tried older FWs but with no luck. But after installing DJI GO 4 version 4.2.6 Android app it started to work. The latest version of the app 4.2.12 does not work... anyone else with the same problem? Do you know if DJI is fixing this?

I have noticed today almost over 5 posts with same Issues. They are installing all Latest Firmware and their Spark cannot Fly, they get a Message - "Aircraft is locked" - ''Cannot take off''.

Can you please solve this issue, many New Buyers, Including Me, need to setup my NEW Spark next week, and I am not risking to get it locked too.

Dear Elektra,
  
  The problem is this -
  
  Version 4.2.12 Launched on Google Play for Android
  
  When you have a NEW SPARK and you set it up for the first time, it is Locking the Drone and after everything is installed it is displaying the message - ''CANNOT TAKE OFF'' in the DJI GO4 App 4.2.12.
  
  After hours hearing problems, and asking NEW SPARK OWNERS, I came up with the Solution -
  
  1) Remove the Version 4.2.12 (Launched on Google Play)
  2) Switch off Auto Updates
  3) Restart Phone
  4) Install old version 4.1.15
  5) Setup the Spark Drone for First Time
  6) Fly it for sometime
  7) Wait a Few Days to see all is ok and do some Flights
  8) If you want Upgrade back to 4.2.12 as Normal (I prefer setting  AutoUpdates to Manual  as this give me chance to Update with my  Confirmation, but as the  4.2.12 is a Really Good Version and wish to  Thank all DJI Support for  helping us, its ok right now to Turn  AutoUpdates on Google Play)
  9) Make sure you have Firmware of Spark Updates / Remote / EACH Battery too.
  10) Problem Solved.
  
  Thats the only problem we encountered, just when SETTING UP the SPARK  for the FIRST TIME, afterwards the Upgrading to 4.2.12 would not effect  the Spark or LOCK IT.
  
  What needs to be done is - Technicians  must import the same procedure of Setting Up the NEW SPARK from v4.1.15  (Works Well) to the NEW VERSION v4.2.12 (Is Faulty). THATS ALL !
  
  Please forward this to your Technical Support Team. I am an Ex IT Programmer, so I have some background about these Issues.
  
  Thank you so much for the Help as always,

Please wait patiently, our engineers are working on it. Or you can use an IPhone to update the database first to unlock the drone. Thanks for your support.
