Ok I was updating my P4RTK from version 02.02.0014 to the latest firmware 0.02.0307 (dated 12-02-19)


update for the aircraft went smoothly, but when I was doing the RC not only was no update available through DJI assistant for phantom (ver. 2.08) but when downloading from within the app on the controller from a WiFi source it stalled at 83.3% and just says that the file verification failed and does nothing (no matter how long I've left it)

I've tried restarting the controller - I can't seem to find the download files on the RC or I'd just delete it and let it re-download


I'm hoping maybe someone could just point me to the firmware file so I can put it on a SD card and hopefully update from that (not sure if that's even possible or not).

Anyhow, like every damn update DJI rolls out there is always issues - now my RC is stuck on ver. 02.02.0014 and my craft is the latest rendering the combination completely useless...I don't have a job until next week so I do have a little time to get this resolved but this is just beyond frustrating...maybe I'll just downgrade the craft and screw all future updates at this point.  

Ok I was able to remove the failed download by swiping to the left on the firmware update.  

Then I found the bin file for the RC  on the following page:   https://www.dji.com/phantom-4-rtk/info#downloads
(download and copy to an micro SD card - install in the RC and then start her up...you should see a system update pop up automatically and ask to install...click install and it will do the firmware update from the SD card - remove SD card and restart the RC - once verified that the update took be sure to delete the bin file from your SD card)

for the aircraft I just used the PC link with DJI assist (v2.08) and it worked first time no issues.  I am using a Propeller PPK solution so no RTK base station upgrade suggestions, but I do have a close friend that told me to reset the controller via the internal settings within the android settings pages

Hello!

I'm fighting this problem in the past few days.. Today I tried this solution, and saw that you wrote the exact same. Sadly, my update process quits at 4% with error code 810.

I use an empty SD card, and clicked all remove options on the firmware page. Though, I didn't get any message back, that they are successfully deleted. Only clicking on delete, then nothing happens. Should it write something? I presume some files are stucked in, which cause this error.

Can you suggest, which files should I delete from the RC, connecting via USB storage? I didn't find anything else other than the DJI->Firm folder..

Any help would be appreciated!

solved with factory reset from the android settings. all apps remains installed after that, but it cleans out the unnecessarry program files

Added an option to control the Terrain Rendering Map Display in the app. When planning a Terrain Awareness operation, users can enable or disable the display in General Settings. This is what the update for RTK Phantom 4 is about. Can anyone tell me where I find the toggle to switch the DEM on or off.

I did not mean to downvote the answer, but clicked it to see if there was a reason people downvoted it.  I'm having a similar problem with reinstalling the current version as well as downgrading to a previous version.  I will need to resort to a factory reboot as well, just wanted to make sure it didn't remove the app.  Thanks for the answer.

I have an update and factory resetting worked perfectly for me!  I am now all reconnected.
