After 2 months not flying (and no prior problems for 2 years), I can no longer connect to the AC. I connect to RC then launch DJI GO 4. On the initial page it says in red "Aircraft firmware has been updated to 0.1.00.1000, and at the bottom left it says "disconnected". If I click "enter device" then "connect to the ac" then "AC combo" then after "install battery" I click "next" it says "start the ac and rc" I click "next" I get a page which says "1. Tap Next after connecting to the RC's wifi" but though I'm connected I don't get "next". This may have something to do with the fact that I'm using an older version of DJI Go 4 (if I use a newer version it did not work properly). If I click the red "ac firmware has been updated..." it takes me to "start updating"  but then to "Tips connect the ac or rc and confirm battery level". Any suggestions?

Hi, Sorry for the troubles that it caused. I would like to clarify if the error message is "DISCONNECTED" or "Aircraft Disconnected"? If the error message would be DISCONNECTED, meaning you have to connect your remote to your phone, however, if its Aircraft Disconnected then it requires to do the linking process between the RC and AC. You can check our video tutorial for RC linking.

DJI Tony, I am having the similar problem. I am able to take off and every thing is working fine. About 1-2 minutes into my flight the screen goes black and states disconnected. Normally it will reconnect but on Oct 3, 2018 it did not reconnect and the spark started to RTH. Which is fine but it was trying to land in a tree about 7 feet away from the set GPS home location. I was able to get RC control but unable to shut off RTH. I was able to stop the spark from hitting the tree by blocking it with my hand. Unfortunately this did damage the led mounts on the left and right front. I opened a case on the same day CAS-2310169-M0M5D3. I was sent a shipping label to send the spark back for repair. All I need is the led mounts. The spark does not need to be sent back. I also uploaded the fight date as requested when I opened the case. This was not a problem until it did the latest Go 4 update to 4.3.3. Both the AC and RC are also up to date.
Any help would be appreciated
Thanks

I was able to check the case number you provided and it seems that our team has already sent you an email for further instructions on how to proceed on the case. Is it possible for you to provide the photo of the LED cover, the Spark itself and a screenshot of a proof of purchase? You may send it via email. Thank you.
