Trying to get my phantom 4 to do imu calibration

[donnie187]

No success getting a successful imu calibration on my phantom 4. I have tried everything I can think of with no success.

and

and last

I have downloaded dji assistant 2 to my Sony laptop running Windows 7 but haven't been able to get the drone to connect using a USB to mini cord that I use on my Samsung s7 phone but it never shows up on the dji assistant 2 page. If there is any pictures I need to post to give a better explanation of what's going on please let me know. I really need help with this.

Kind of looks like a bad board. Did an update fail?

Check this out

this is from the control board here's another view

I replace the ribbon last night with a new one from dji and reassembled and powered it up and the same thing happened to the new wire. I ordered a new control board last night so hopefully that's it. What's anyone's thoughts on this.

I'm missing what's wrong with the ribbon cables you removed

If you look at the 2 cables in the first photo, the top cable has a burned out section going across it. There must be a short and it could be the processor board ( the gray one)

Need to take care of the abnormal firmware. That isn't the problem but if they don't match sometimes people can't even fly.

Was there a crash bybthe way

No crash that I'm aware of but I did purchase the drone used. I replaced the flight controller board with new ribbon wires and that fixed all my problems. I updated firmware and now I'm ready to get back in the air.
