Upon reviewing your picture above a little closer, the warning box says:
It is either a bad firmware install or your Tx is not calibrated!
So let's go back to the basics:
First:
Download and install ( DJI RC ASSISTANT ) if you have not already from DJI.com
Next
Download and install ( DJI PC ASSISTANT, and DRIVER ) if you have not yet
Once installed
If your Tx does NOT have an external USB on it, remove 4 screws on back, open Tx to access internal USB. Use supplied DJI data cable ( USB to miniUSB CABLE ) hook Tx to computer, run RC ASSISTANT.
Turn on remote, wait for a link ( you'll see 2 lights flashing bottom of computer screen ( 1 green 1 blue )
Once linked, CALIBRATE BOTH STICKS, " U " ( S2 switch ), " X1 " ( note below ), and " X2 " ( S1 switch )
( note X1 only if you have dial wheel Tx, or 7th channel mod ( lever on rear of remote to tilt camera )
Turn off Tx, then back on, make sure nothing changed, and calibration took! If Ok, turn off unhook plug, close RC assistant! Put remote back together, replace 4 screws, CAREFUL NOT TO PINCH ANY WIRES INSIDE TX.
( also if you are switching your switch, but nothing is happening on assistant, than your switch is bad! Needs replaced )
Next
Open PC ASSISTANT, plug the plug on phantom this time. Turn on Tx, then phantom, wait for a link ( same 2 lights blinking )
Now
Open BASIC TAB
Then open RC TAB
now calibrate BOTH STICKS, click finish ( follow warnings onscreen ), next calibrate X1 ( if applicable ) and X2 click finish
Ok
Now open TOOLS TAB
SELECT ADVANCED TAB bottom left.( MAKE SURE BIRD IS SETTING LEVEL, and firm ( no wobbling, ect )
Run ADVANCED IMU CALIBRATION, IGNORE overheat or IMU too hot warnings, as it always says that, click through it, let it finish calibration.
Turn off phantom ( also known as power cycle ) while still hooked up, turn it on again, double check all changes stuck, if all good turn off everything, unhook bird, close assistant.
Now final step
Go outside ( in a field or somewhere away from power lines, cables, metal, ect. Now do a compass calibration ( DJI DANCE ), switch S2 up-down-up-ect several times until phantom lights turn solid yellow ( if switch don't work, you can calibrate though app as well!
( you might want to make sure app is up to date )
That is it!
( if that does NOT WORK )
Then REINSTALL ALL FIRMWARES, Tx and bird!

Good luck! Keep us up to date!
