If you're using your Phantom for quantitative remote sensing applications (taking video/pictures in a very careful way to extract 3d feature data from the ground, for instance), do NOT upgrade to firmware 1.4.10.  This version of firmware apparently will not validate missions (and therefore not allow them to run) when the waypoints are too close together.  4ft is apparently too close, 10ft is apparently not too close when tested on my P3P.  The previous SDK firmware did not have this restriction and I ran many successful missions using Ultimate Flight on Android.  Now, DJI's firmware has bricked my Phantom with regard to being able to fly those same missions.  What's worse is that I'm told reversion to previous firmware versions is impossible.

This is a horrible regression on DJI's part and it should be fixed ASAP.

You can roll back your firmware to 1.1.9 and then install whatever SDK firmware you were working with. Maybe it is a good idea to read the release notes that came with the firmwares.

yea, where? I'm having different issue but I checked the release notes and there is nothing about my thing or yours, so I clearly see that the guy above just posted useless comment just to only comment stuff... : / c'mon people, be useful on forum not making trash.

The release notes the "guy above" was referring to were the notes on how to roll back your firmware, nothing else. You can actually go back to your earlier firmware and get those old features back, if you read the release notes regarding FIRMWARE ROLL-BACK, not waypoints.

Actually, it's not correct that you can get those old features back.  It is possible to roll back to 1.3.20, but this version does not support the SDK.  It is not possible to roll back to 1.4.1 (the version I was previously using successfully) or 1.4.5.  It is also not possible to roll back to 1.3.20 then "upgrade" to either of these versions.  You can have 1.3.20 or you can have 1.4.10, but you cannot have any firmware version that actually lets you run small-movement missions.

Here's my chronological firmware update log.  Note the failed attempts to go to 1.4.1 and 1.4.5 after earlier updating to 1.4.10.

I've copied the entire release notes section for the latest release into this post for reference.  Note that it does not say anything about the issue I posted about.  It also does NOT say the firmware can be downgraded to 1.1.9 as you claimed (perhaps you didn't read the release notes?), but rather only 1.3.20 or later.  The release notes also don't explain how to roll back the firmware, contra your claim.  My above post shows how it is actually impossible to roll back the firmware to something in between 1.3.20 and 1.4.10.  Problems with reading? Go check yourself before accusing other people.

2015.9.7
Overview：
1. All-in-one firmware version updated to：v1.4.0010
2. DJI GO app iOS version updated to: v2.2.0
3. DJI GO app Android version updated to: v2.1.0
What’s New：
1. Added Intelligent Navigation Modes including Point of Interest, Follow Me and Waypoint.
2. The photo format now cannot be changed when the camera is in operation.
Bug Fixes：
1. Removed the vision position system altitude record from the video caption.
Notice：
1. Firmware update v1.4.0010 does not include a remote controller update package. Users using older
firmware are recommended to update to v1.3.20 before updating the aircraft.
2. It is normal for the motor to sound or the LED to blink during the update process, as the latest firmware
update will affect the motor.
3. The firmware can be downgraded to v1.3.20 or later only

Here is my transcript with DJI support:

Hello,welcome to our website!How may I help you today?
13:47:59
I upgrade my Phantom 3 Professional's firmware to 1.4.10 but discovered that it has minimum waypoint distances making it impossible to fly the automated missions I was previously flying with 1.4.1. I want to downgrade the firmware to 1.4.1, but the Phantom won't let me ("The current firmware does not support downgrade. Use a different version of firmware to downgrade the target version."). How can I downgrade to 1.4.1 from 1.4.10?
I have also tried downgrading to 1.3.20 (success) and then upgrading to 1.4.1. That does not work either.
After downgrading to 1.3.20 successfully, I was then able to upgrade back to 1.4.10 successfully. But I was unable to load firmware 1.4.1 after "upgrading" to 1.4.10.
13:50:09
Customer service is for your query,please wait for a moment,thanks!
Ok
13:51:19
Customer service is for your query,please wait for a moment,thanks!
Ok
Ok, were you sure to format the sd card?
13:52:43
Yes, and I was able to change firmware versions from 1.4.10 -> 1.3.20 and from 1.3.20 -> 1.4.10, but not from either of those versions to 1.4.1. The message I receive in my P3X_FW_RESULT_AB.txt file is:
========== 2014.01.01 00:00:12 remo-con disconnect======
Packet: P3X_FW_V01.04.0001.bin
Result: Abort.
The current firmware does not support downgrade. Use a different version of firmware to downgrade the target version.
The Abort message means that there is no need to update.
There is a need to update. I want version 1.4.1 because 1.4.10 breaks functionality I was previously using successfully in 1.4.1.
Have you connected to the app yes?
13:53:45
You can check the current version on the drone there.
Yes, via Android devices
Yes, the current version on the drone is 1.4.10
I want it to be 1.4.1.
The 1.4.001 is the current version.
That is the latest.
No, the current version is 1.4.0010: http://download.dji-innovations.com/downloads/phantom_3/en/Phantom_3_Professional_Release_Note_en_9.9.pdf
13:54:46
That is the latest version.
The only version that is current is 1.4.0010
Yes, correct
I want to downgrade to 1.4.0001
13:55:57
The release notes say "The firmware can be downgraded to v1.3.20 or later only." I want to downgrade to 1.4.0001, which is later than 1.3.20, but earlier than 1.4.0010
Sir, the firmware you have is the latest.
13:57:01
Are you referring to the way it reporst in the app?
Yes, that is correct. I want to downgrade to 1.4.1. "Downgrade" means "use an earlier (not current) version of the firmware"
The earlier version was 1.3.2
There is no 1.4.1
Yes, there was 1.4.1 -- it was released to support use of the SDK before 1.4.10
13:58:05
There was also a wide release of 1.4.5 after 1.4.1 and before 1.4.10. I heard there was also 1.4.8, but I do not believe that one was widely released.
http://www.dji.com/product/phantom-3/download
If you click on the link you will see the only available firmware versions.
Those are the production releases. I am a tier 2 SDK developer and have both 1.4.1 and 1.4.5 bin files.
Ok, now I understand.
13:59:55
Customer service is for your query,please wait for a moment,thanks!
Ok
In that case, you will need to send an email to the Development department and request that information. I have no knowledge of those versions. I can't even confirm that they exisist.
Ok, what email address should I use?
We do not support the SDK program.

Ok, thanks

First of all I don't accuse anyone of anything. After all it's not my problem but I'm willing to help. appreciate  that! So, when you continu reading you see the release notes for 1.3.20 There it says you can downgrade to 1.1.9. So first you downgrade to 1.3.20 and then to 1.1.9. This is the lowest version you can downgrade to. O, and there is no official firmware between 1.3.20 and 1.4.0010.

There is no general-release firmware between 1.3.20 and 1.4.10, but yes, there is official firmware between those two versions.  One of those official releases (1.4.1) works fine with close-waypoint automated missions.  But if you upgrade to 1.4.10, there's no way to get back to that working state as far as I know.

So, you are a developer, yes? And you need to discuss this stuff in a normal users forum? OK, everything is clear, discussion closed as far as I'm concerned.  O, and one more thing: DJI didn't brick yhour Phantom, you did it yourself by installing a new firmware without checking if it would suit your needs. Not very professional, so blame yourself.

No offence intended.

giant Posted at 2015-9-22 02:57
No offence intended.

Uh huh.

I have not developed anything myself but I have been using the SDK firmware (as mentioned in the original post) to use third-party apps as this was the only way before 1.4.10 -- this firmware is available without a subscription from app developers, but you asked for the official version.  DJI did brick my Phantom for the purposes of this mission, unless your position is that everyone should first install new firmware on someone else's Phantom before installing it themselves to see if all the features they use are still there.  My position is that 1) DJI should not disable useful features, but failing that, 2) DJI should not prevent me from rolling back to a previous working firmware version, but failing that 3) DJI should document that it is not possible to roll back to a previous firmware version.  Which of those do you think is unreasonable to expect from DJI?
