I will post this again and hopefully this gets you all up and running. If not, then please contact support.

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.

You do not have to update if you do not wish to.

You don't understand. I want to update, but it shows no new firmware...

Edit: Did the Academy trick again. Unknown firmware on my controller though I did never install it from DJI Go app. Downloading the 1.5.80 and will try to flash it.

For me, the best way to update the app for iOS is to open the DJI Go app on your mobile device and click on the firmware update that is in red at the top of the page. Simple as that. I think we're all getting mixed up because there are two ways to update- through the DJI Go app or through the software download. Then you have people with either a mac or windows machine on top of that two mobile platforms- iOS or Android. DJI's communication to its customers is very weak. They need good technical writers who can relay the information correctly and clearly because there are a huge number of customers that are new to flying.

This is the issue I was having

I can now see what the issue is, the firmware update to the aircraft failed when I did it I thought it had completed so I then did the RC
DO NOT UPGRADE THE RC BEFORE YOU UPDATE THE AIRCRAFT this is what is causing the issue of unable to connect

Wow this is so frustrating.  I think I'll wait a week or so and see if the firmware upgrade process has been improved.  Just can't get it to work but my P4 is working great with old firmware so all is not lost.  Really hoping DJI fixes things on their end and provides us with some clear and specific step by step instructions.

Just updated mine, I'm running PC / Android.  I updated the P4 using the DJI Assistant2 and the RC using the GO app.  The whole process from start to finish took about 15 minutes.

I'll test fly tomorrow but everything seems to be normal.

Check your OS firewall. I manually allowed DJI Assistant 2 in Windows 10 firewall and now I got a firmware listing. Upgrading now as I write. I don't know it was the firewall setting that did the trick, or if I was lucky to get a connection that I did not get before with the servers.

Well..   I got mine out of the box.   Connected everything up.  Did the upgrade by following the instructions on the screen of my iPad Air..   The controller upgraded with lots of beeping.

After that, All that was left on the upgrade screen was "Download new firmware from DJI".  Nothing was happening, there were no lights or progress bars to let me know that anything was going on.

I shut everything down and went looking for the new firmware at DJI (Which I can't find).

When I started up again, I get RC Signal Lost and have solid red lights on the drone.  It is sending video.

Is this fixable and if so, how?

Thanks in advance

I'm having the same problem. I reverted the controller back to 1.5.8, but the aircraft update never shows up. And trying to do it with the Assistant application fails repeatedly.

Ok, finally done upgrading. I never did get confirmation of a new aircraft firmware in any DJI Go app (nor on iOS or Android), despite waiting for about 10-15 minutes. I finally got lucky with after several tries on DJI Assistant 2 (I tried first on Windows several times, then on OSX several times, and then back in Windows again).

I hope that the Phantom 4 in the future will support SD card firmware upgrades, just like the older Phantoms and the Inspire. This upgrade took me 4 hours.

In a few posts above, I mentioned a tip to open the firewall. After my success with the upgrade, I went back and tried to list firmwares, It took about half a minute, then it listed the firmwares. So for you who have problems, it *might* be a firewall issue. Or, it could be that the update servers had problems and are working *a bit* better.

I've actually been following this thread in the 2 days it took for the P4 to arrive.  I've tried just about all the suggestions:

Is there some way to download the firmware from DJI and put it on a memory card?   I can't find anything like that on the download page.

Here is my screenshot:

Ken, I can't seem to downgrade the RC because it will not give me the option to pick any firmware via the dji go app downgrade path. I am not able to get the Assistant app on my Mac to get a list of firmwares available period. I would hope that we could just stick the USB with the firmware bin in the USB port on the RC and get it resolved. Or insert the MicroSD in the P4 and be able to upgrade... Also it would be nice to include in the release notes the warning to upgrade the aircraft first and not the RC... I upgraded the RC because it did not show that the aircraft had an update available... again not very good communication on DJI's part...

Thank you for the screenshot, the reason you have no signal is because your RC is updated but the aircraft is not. Please try to downgrade the RC to 1.5.8 in the instructions I posted earlier. Then start all over again but do the aircraft first and the RC last.

Are you following the instructions I posted earlier and pressing down on the graduation hat icon for about five seconds. You have to have the RC only turned on and connected to the app with the USB cable.

I upgraded per the instructions on this thread - was NOT able to upgrade through the DJI Go app (notice to upgrade aircraft never came up), so I updated through DJI Assistant.  Does this cover the upgrade for both batteries as well, or do you need to do anything different for the batteries?

I do not know if you need to update the aircraft first before the RC. That was just a solution that I found that worked on the aircraft that I had updated personally. I see your screen shot in the app and do you have the RC connected and  Howard on? If so then go to the about page in the aircraft status and post a screenshot of what everything says. And make sure to have the aircraft turned off when you do that.
