Purchased a P3 Pro from a friend who hadn’t updated the firmware (still on 1.1.8).  Got the AC firmware to update fine, however RC would not update to latest version.  Found a link to version 1.2.6 online and was able to get it to update using usb.  So it seems if your firmware is way out of date it won’t let you jump a lot of versions.  Now I just need to find versions between 1.2.6 and 1.11.20.  Anyone know where I can locate these?

For the RC update of P3P, you need to download the firmware of 1.3.20, and copy it to the SD card to update.

Here is the link of downloading 1.3.20 version: https://www.dropbox.com/s/i8iao2 ... 01.03.0020.zip?dl=0

After upgrading to 1.3.20 successfully, you can update the RC via DJI GO to the latest version.

Thanks!  It's updating now, taking a really long time though, and no status bar.

Ok, it beeped a long time because it "failed to update". The update downloads via the dji go app but won't install.  Keeps doing this

Ok update, swapped out my iPhone for an iPad mini, re-downloaded the upgrade and was able to re-install without issue.  Had to go through re-linking AC to RC, but works great now.  Thanks!

Glad to hear that you have figured it out. Enjoy it and happy flying!
