It's been a day so I'll just say the obvious.  Make sure there's no sand in the motors.  Spin them around with your fingers before you boot up.  If there's sand, get it all out.  I would remove the motors and blow them out carefully and thoroughly.  Good luck.

Thank you for your response. Can you please check the motors of the unit if there are dust or sands inside and try to remove them without removing the motors on the unit? Also, can you please provide us the latest version of the firmware that you are currently using for us to check if you have the latest one. Please keep us posted. Thank you!

Good day
This is the latest firmware..
  App   3.159
  Version   1.10.90
   R/C    1.9.2
  Just one more thing i noticed, only the back 2 lights on the drone flash when trying the start-up, not sure if the front 2 are supossed to light up...
Back is the opposite end to where the camera is facing...
Hope this helps
