If you experience a RC signal lost, delete and reinstall the app and you will be fine.

I've done Ken three times now.  I'm still getting the Rc error.  What do I do?

Can you tilt the camera with the tilt wheel or does nothing work in the app.

Do we know why the settings do not stick after a firmware update?  It's an inconvenience that I have to go in every time to update the settings?

I've tried DJI Assistant 2 on both PC and Mac. It is just a spinning wheel, it does not show any firmware at all.
Connecting to the RC/aircraft via IPad Air 2 and DJI GO, it only shows that there is a new firmware for the RC (no new for the aircraft).
Connecting to the RC/aircraft via Android and the new DJI GO, it only shows that there is a new firmware for the RC (no new for the aircraft).

In DJI GO App, it says following firmware versions are installed:
Aircraft: 01.00.288
RC: 1.5.80

Is the aircraft firmware pulled?

Ken, I don't see a reset button -- as displayed in your diagram -- on my Phantom 4.
My status says "RC Signal Lost".

My app version is iOS 2.7.1, Aircraft is 01.00.0288, and my RC version is 1.6.0.

If your aircraft is on 01.00.0288 then there is an update for the aircraft. It will show up in the aircraft status then "overall status" page. It may take a minute for the "aircraft requires update" to show up.
And your RC is not updated as well.
So you should be able to fly and have no errors correct?

Go to the About page and if the aircraft is not on 1.1.301 then there is an update.
From the home page and everything powered up, press the top middle tab, then tap the overall status and wait a minute and if your RC or aircraft needs updating, it will say.

If your RC is on the latest 1.6 firmware and you cannot get the P3 to update through the app then downgrade the RC and it will take it to 1.5.8 as you can see in the images I posted.

I've tried this on both DJI Assistant 2 on Mac and on Windows. The update shows up on both, yet when I choose to install it, it consistently reports the update as failing.

PS, it takes a l-o-n-g time for the updates to show up in the list of available updates... like 5 minutes at least.

Here's my app screen after only being prompted to upgrade the controller:

You will see RC Signal Lost if BOTH the aircraft and RC are not updated.
If you are updating through the app and updated the RC first and now have the "RC Signal Lost" and the aircraft will not update, then downgrade the RC to 1.5.8 (instructions posted in this thread) and restart the firmware upgrade process and UPGRADE THE AIRCRAFT FIRST, then the RC.

JCK, I am in same boat as you. Finally, I figured out that to downgrade the firmware in your RC, you must turn OFF the drone. Then, connect to your RC and turn it on. Then, launch your DJI Go app. Press and hold on the graduate hat icon in the upper right corner of the screen for 5 seconds. When you release, you'll see the firmware version 1.5.80 available. Hope this help you.

Removed DJI GO from my iPad Air 2, reinstalled.
Now RC is unknown, Aircraft 01.00.0288
Overall Status Normal (Latest Firmware)

Waiting several minutes for it to update, but it does not.


When doing the Academy trick, it shows no firmware to downgrade to.

For those who are having trouble with the firmware update on your P4 and getting RC Signal Lost it means that you do not have the update done on both the Aircraft (1.1.301) and RC 1.6). This means you probalbly uodated the RC first, If the aircraft will not take the update, you can update the aircraft through the Assistant2 PC or Mac program.
OR, downgrade the 1.6 RC firmware to 1.5.8. To do this, from the home page upper right corner is a graduation hat icon. That takes you into the Academy section of the app when you press it.

Have the RC on connected to the app and the aircraft OFF.
DO NOT give it a quick press, instead keep it pressed down for 5 seconds or so and let go. Then you will see the RC firmware downgrade to 1.5.8 page.

This should take care of the update, and it takes a wile to update the aircraft firmware.

No Signal after firmward update

I have the Phantom 4 with a Galaxy Note 3 (Android). My problem is similar to the above threads. I get "No Signal" error. Can't warm the motors, no control over camera and can't take off. The downloading part took several attempts and failures. I did the RC first then connected directly to the Drone. Still not sure if all went correctly since there wasn't any indication updating was in progress.
I found a solution by doing this:

http://forum.dji.com/forum.php?mod=redirect&goto=findpost&ptid=48126&pid=369566&fromuid=275427

Relinking RC to Drone needed.
Push in link button next to SD card slot. Same hole as LED light.

Press the C1 + C2 + REC buttons simulateously for about 3 secs then release.

Then push in the camera control wheel in (right side) until it beeps and new sound.

Reattach cabels if not already connected. Recycle power in both the RC and P4.

Check firmware updates.

At this point is where an update was required for the P4 (Drone only). I connected the cable from phone to P4 and waited a few seconds to view the app with Firemware upgrade needed. Followed instructions until completed. Problem resolved.

Ken,
What shall we do? I have not upgraded the aircraft nor the RC with these new firmwares for the aircraft and RC, because it shows like everything is ok (ie no new firmware release). Are the upgrade servers down or something?

The best I got from DJI Assistant 2 firmware upgrades was that I could press Retry two times. Then just spinning waiting wheel.

Yes, my internet is fine. I'm used to flash since I'm in DJI Beta also.

Turn off the aircraft, and only have the RC powered up.
Your screen shot shows the aircraft firmware so that means you have it powered up.

Don't update!!! , after update display signal lost, and you can't take off

For some reason  only the RC update is available on the iOS DJI go app.  If you update it you will lose RC signal. To revert back to the previous firmware turn off your phantom 4.  Connect your phone or tablet to the RC and turn on the RC only. Open up the DJI go app. Press and hold the graduation cap for about 10 to 15 seconds and then release, you should be on a screen that will allow you to swap your firmware back to the previous version. I guess we have to wait a little longer for the Phantom 4 firmware to become available

You say the RC upgraded fine but the aircraft will not.
Please power off the aircraft and only have the RC on and downgrade the RC to 1.5.8 with the instructions I posted a few posts ago.
