If DJI were at least honest in their firmware notes then people could make an educated desicion on whether they consider it viable for them to upgrade or not.

The problem is DJI are not forthcoming with documenting all the changes they make from one version of FW to the next.
It seems the itemise some things in their release notes but have a dabble around and tweak a few things behind the scenes but do not actually tell anybody.

The latest incarnation of code in v1.9 is a case in point. Are users really expected to believe that simply updating a NFZ database (which is the only thing mentioned in the release notes) makes the aircraft change altitude like a yo-yo with no stick input from the user? Something else has been altered in there linked to barometer function else this wouldn't be happening.

Come on DJI, don't treat your user base and customers like idiots...........start being honest!!

Thank you, Tahoe and Paladin.

I was amongst the first few I1 flyers who experienced the issues after upgraded to FW v1.09.01.10. The issues were intermittent - issues appeared when setting off the aircraft after it was switched on, landed it with lots of throttle compensations, and then it behaved normal again after reboot the aircraft.

A week after experienced the issues, I re-calibrated the IMU, did the compass dance, and it flew consistently normal again for several flights in 2 days, so far so good. I had not downgraded the FW.

It appears to me that with the FW v1.09.01.10, somewhere in time the Flight Controller was busy in doing something (as if the recurring of a subroutine loop in a programme that ate up all CPU resources) that rendered it not being able to either collect the barometer or VPS readings. Rebooting of the aircraft killed the loop, I think.

Whilst I trust DJI R&D might have collected sufficient flight records of us and are proactively diagnosing the issues, I hope you or Paladin can relay my 2 cents to your R&D colleagues. Every piece of clue, no matter how small it seems, might help figuring out the issues earlier. And I do wish DJI success in tackling the problem in the near future - we all are looking forward to it.

Hi.  I'm a brand new owner - Inspire 1 V2 X3 so be gentle with me.

As advised by DJI I ensured I updated the FW before using the aircraft and have only had a couple of opportunities to fly.  On my first outing after 2 or three TOs and landings I got the ultrasonic warning and failure to lower the legs.  I landed and returned home assuming it was perhaps a glitch down to local conditions or lack of experience on my part. I had calibrated the compass but no the IMU so thought this may have had something to do with it.

I next did a full IMU and compass calibration and had a couple of flights in the garden - no problems.

Then yesterday I had an experienced flying friend around and put the Inspire through its paces for him to see.  The first couple of TOs and landings were fine.  I then recoded some waypoints and got the machine to re-fly these - all impressive stuff.

Then it all went wrong.  I put the Inspire back into P mode and took off using auto take-off.  It launched itself high into the air - no landing gear raised - and continued up.  I got some control of it at about 30-40 ft but it took some effort with the stick to bring it down safely.

Am taking DJI's advice and reverting to 01.08.01 and hope this will resolve all issues.

One question though.  Once updated do I remove the BIN file from the SD card?  Also, how do I go about downgrading the controller?  IT doesn't seem to want to fall back to a lower release.

Grateful for any guidance from more experienced users and not too happy with DJI for such a slow response on this forum.  Looking forward to a thoroughly de-bugged upgrade from them soon!

Hi Grahamdegg,

Once you completed an upgrade (or a downgrade) of FW and ascertained it from the txt file and the hidden log file (in a hidden folder) in the micro-SD card, you should remove the BIN file from the micro-SD card.

You don't need to downgrade the Remote Controller though - it has to be on FW v1.6.0 for communicating with the aircraft, no matter it is on FW v1.09.01.10 or FW v1.08.01.00.

Hope this help.

Henry

You be fine keeping the Bin file on the card, I use 2 cards, the DJI supplied card for Firmware update only and a second card for normal use.

No need to downgrade RC between 1.8 and 1.9.

Long time ago, I suggested to DJI to make the firmware notes more detailed. Here is my original thread about my suggestion of better firmware release notes: http://forum.dji.com/thread-39400-1-1.html DJI-Tim thought it was a good idea, but so far I haven't seen much of an improvement in the release notes.

Now the release notes are in my humble opinion to generic. Often there are a few fixes, but then there are a lot of stuff that are not written into the release notes that users finds out afterwards (might be known bugs, might be things changed that affects something etc). Perhaps a lot of crashes could have been avoided and a lot of repeated questions here in the forum would not be needed with proper release notes and documentation to the users. Also, when several users report the same repeatable issue, DJI should take a quicker approach to the users.

the firmware upgrade report should also list the components with the release numbers. This will enable us to see exactly what had taken software changes.
e.g.
Component name one: existing release number and new release number
Component name two: existing release number and new release number

Hi Donnie,

Thank for your appreciation.

I just did what I could, hoping in return that we, as customers of DJI, can eventually enjoy a reliable flying platform for taking aerial photos and footages.

Some could have just ignored any issues they encountered without providing feedbacks to DJI.

Not me.

Keep up your good advices to folks here. A lot of us are benefitted from you Donnie.

or take v1.9.1.10 off

One possibility is the tolerance of each electronic component in the circuit.  If the firmware is written for a certain tolerance level, and each component is slightly above or below the spec, it will behave differently.

Even in full scale aircraft avionics, consumer grade components are used - however each part is tested and either accepted or rejected for use.  And certainly different then a product like this, an aircraft radio, transponder (or any TSO certified product) is run through a battery of tests upon completion.  My brother is a test engineer for a major avionics mfg, and I've watched him run units from 125 degrees F to negative 100 degrees F in less then 2 minutes, while on a vibration table for 10 hrs prior to shipment to a client.  You would be amazed how the tolerance spec can swing on a component, and of course this is the major reason why equipment in a passenger aircraft costs so much.

Tahoe,

I'm trying to post an email I received from DJI to verify it's authenticity.

Hi Linolens
Did you contact DJI support about this problem? if you did not then it might be a scam.
if you did then when support send you an email, they will mention your name in the email, not customers.
I think you should use online chat and talk to Hong (ask for Hong) to confirm the email and link.

I did not contact DJI about this problem.
That's a good suggestion.
thanks

Guys,
DJI is working on this and a fix will come soon to everyone.
Probably related to different regions and batches of i1 involved , but that's me talking out of my back end.

I also got a email with attached Fw file for my Inspire. I am on travel and it will be some days until I will be able to check this out. I hope some of the Dji folks on this forum can check it out for us.

Hi, Linolens,

I confirm I also received the same email which appeared to me from DJI. I have sent an email to DJI Support requesting for DJI's confirmation on the authenticity of the email and hence the two "internal firmware" it pointed its links to. Also asked DJI to confirm warranty issues if upgraded with the linked firmwares.

I downloaded the two internal firmware files, but will not upgrade until DJI's affirmative confirmation.

Mine did the same thing on firmware 1.9 Henry. Luckily I had read this thread so I identified the faults as soon as they happened. Was hard to land softly the first time as it was descending on its own. Have downgraded to 1.8 until they fix the bugs. Have never had any problems with the inspire until this latest update

Hi Brendanabbott,

The issues were intermittent - I first encountered the issues twice amongst several normal flights on 19 Jun 2016. One week later, after completing IMU calibration I carefully flew the I1Pro - no issue at all during the several flights on 25 & 26 Jun 2016. Today I encountered the issues again, exactly the same uncommanded climbing without autoraising landing gear. I have not downgraded and am still at FW v1.09.01.10 at this moment.


It seems to me DJI has been working hard in diagnosing and addressing the issues - I received an email from DJI with hyperlinks pointing to two files referred as "internal firmware" for Inspire 1 & Inspire 1 Pro respectively. I downloaded the 2 files and am considering upgrading.

Will provide any findings upon completion of upgrading with the "internal firmware" and test-flying.

Henry

vincentlublink@ Posted at 2016-6-30 21:31
thake the update of from the website before more people have issues withe the latest update!!!!

But to do that would mean an admission something is wrong which DJI as a Chinese company is culturally incapable of doing.

It will be 'Fixed' but nothing was ever 'wrong' in the first place

I just called DJI and they are unaware of any "internal firmware.".........  Just thought I'd check on it.

Hi Folks,

I have upgraded my I1 Pro with the "internal firmware" from DJI Support Team and tested it out in this morning with 4 packs of batteries (8 taking-offs & 8 landings). I would like to advise that the I1 Pro with the "internal firmware" consistently performed as it should be, with both X3 & X5 attached.

I am looking forward to DJI's official release of the firmware after DJI has received further feedbacks from other Fellow I1 Owners to whom DJI sent these "internal firmware" and from their own tests.

In the mean time, I wish all who upgraded to FW v1.09.01.10 good luck!

Happy and safe flying!

Henry

Thank you, Lino.

Without your advice on the confirmation from DJI in relation to the authenticity of the email and the 2 "internal firmware" files, I might still be hesitating to upgrade the firmware.

It appeared to me you had edited your post several times, didn't you? Were you asked to do so?

Nevertheless, I hope we all will soon receive the official firmware release from DJI. A lot of folks here need it.

thank you for reporting back your findings   It is good to hear they have worked correctly on your Inspire 1 with both cameras. I wonder how long it is going to take before they release the FW as I have downgraded mine even though it was not acting up. I have noticed during filming this week the inspire would sink several feet by itself and I held up-stick to keep it in one place.   It has never done that before

Hi Rich,

The FW upgrade processing from FW v1.09.01.10 to the DJI's supplied "internal firmware" only took less than 5 minutes, and in fact only device [17 00] was upgraded. I have no idea on which device in the Inspire 1 this device [17 00] is, but my observations in this morning's tests after the upgrade were that the Inspire 1 Pro held altitude quite well - rock solid as before.

I remember in FW v1.08.01.00 my Inspire 1 Pro did change altitude sometimes, and I thought it was due to windy condition. Please see my case in this post. inspire rising or lowering when landning gear changed
