    I'm going to try keep this simple and direct.

    I reverted back to 1.08 firmware after updating to 2.0 then 3.0 because the craft would not maintain elevation and overall general decrease in control. After reverting the craft controls the way it used too ie. very good response and feel. It was very easy to revert since the DJI software never uninstalls the previous version of the Assistant software, my PC has versions 1.0, 1.02, 1.08, 2.0 and 3.0. I simply ran the executable for 1.08, plugged in the Phantom, checked for updates and it said I could "update" from version 3.0 to 1.08, seems any variance from the current version is seen as an update, this happens to make things very easy. I do have a lingering issue I will be working on today, that is my Gimbal no longer works, it stopped working after the update to version 3. I have the Zenmuse H3-2D gimabl.

    Now before I start getting a bunch of advice please read these clarifications below. PS. I re-calibrated everything via the software after every version update, as well as re-calibrating the craft as well.

    1. I have flown my Phantom 2 for 5 months EVERYDAY for an hour at least. This is the only way to become a good pilot.

    2. I do lots of low flying over water, very delicate flight patterns, NO room for error.

    3. I never update firmware unless I have an issue, don't fix it if it ain't broke.

    4. I decided to update from 1.08 to 2.0 for one reason only, I loved the new max descent speed limit since my one and only crash was due to a very high altitude descent in stormy conditions and came down too fast and without enough forward/backward movement and entering into the wobble of death/vortex ring state and the craft plummeted to the ground. I now know that if I enter this state simply back of the throttle and give it forward or backward stick gently.

    5. As soon as I updated to 2.0 I began to notice flight control issues, to be specific, the craft would no longer MAINTAIN altitude at hover and also when you moved in any direction the craft would lose altitude, I nearly ditched the craft into the water several times before heading to the backyard for some serious flight analysis. I verified that the craft no longer moved or responded in the same way it had for the previous 200 flights, I was always having to add throttle up to maintain elevation, with no control movement at all the craft would drop several feet and rise and fall slowly over and over, when moving in any direction the craft would lose elevation and lastly when I would do a big pull back shot ie. Backwards and up at the same time it would "hook" left as it flew away, not a hard hook but a hook. I do this type of shot every day and do know that a compass issue will cause the same thing, but remember I recalibrated my compass before each flight just trying to eliminate variables.

    6. Next I upgraded to 3.0 just in case these were version bugs, they do occur, I am a programmer and I know how easy it is cause issues with "improvements" and debugging can take time. The flight control issues remained PLUS now my gimbal would not work. I did extensive flight tests, low level, hover, pull backs and all the conditions existed. Keep in mind I performed all tests in exactly the same location as to not introduce any locations variables.

    7. Frustrated I got up this morning and decided to attempt a roll back to what IO deemed the last stable version 1.08. I read the forums but there was way too much conflicting and emotional dialog to sort thru so I decided to just give it a whirl. Since the DJI software never uninstalls the previous version of the Assistant software I DID NOT have to locate the installer for 1.08 or uninstall 3.0, all the older versions still existed in an installed state on my PC. I had versions 1.0, 1.02, 1.08, 2.0 and 3.0.
    a. I simply located the executable for 1.08 C:\Program Files (x86)\DJI Product\Phantom 2 Assistant_1.08\Phantom2.exe
    b. Plugged in the Phantom, checked for updates and it said I could "update" from version 3.0 to 1.08, seems any variance from the current version is seen as an update, this happens to make things very easy.
    c. I then recalibrated the controller and went to do some hands on flight tests. Everything is now great again, all the previous issues were gone, no drop in elevation when moving, much more stable hovering and no more J hook on the big pull backs
    d. I do have a lingering issue I will be working on today, that is my Gimbal no longer works, it stopped working after the update to version 3. I have the Zenmuse H3-2D gimbal.

    I truly hope this info is helpful and would love to get your feedback. I love to fly my Phantom and know how hard it must be for DJI to manage hardware and software changes and also know they are trying to beat the governments to the punch at protecting airports and aircraft from careless pilots, I think this is a good thing for the sport.

    EXACTLY my findings too - thanks for typing all that up.

    I'm sticking on 1.8 for as long as possible, I have faith in my Phantom on that firmware but ZERO faith when I went up to 2.0

    My Gimbal tilt control is still not functioning, hoping I can find a fix in the forums, probably a sequence issue in terms of upgrading/downgrading versions. To be claer the gimbal is keeping the camera level but the switch on the transmitter no longer works to articulate the gimbal in its normal 90 degree movement, basically the gimbal swicth on the controller will no longer work to articulate the camera.

    Re-calibrate the X1 (Gimbal Switch) using the Assistant Software, go to Basic, then RC, then go to the Sticks Monitor and click Start in the X1 calibration, articulate the gimbal switch, then click Finish and all will be well.

    So all you had to do to downgrade the firmware was install the old v1.08 installer? Or am I missing something?

    Note that the assist still have to download the actual firmware from DJI server. So do whatever downgrade you think you need ASAP as DJI may not keep those files around forever.

    To calibrate X1, you have to follow VERY STRICTLY the steps recommended by DJI:

    1. Calibrate the stick in the RC Assistant (note that X1 cannot be calibrated in RC Assistant);
    2. Calibrate X1 through Phantom Assistant.

    If you do step 2 first, you will have no control on X1 no matter how many times you repeat Step 1 or Step 2.

    The ONLY solution is to "upgrade" or "downgrade" P2 and then perform Step 1 and Step 2 again in that order.

    I lost my X1 control and resolve it by using the above method. Hope this is helpful.

    Thank you so much Raptor…it worked!! You're a lifesaver…or a Gimbal saver I should say LOL….Now I just hope this 1.08 downgrade helps the flying…3.0 almost caused me to crash a few times with the way it was drifting and not stopping when I wanted to, it was j hooking..had TBE…this is my first quadcopter and so far I am kind of disappointed with the problems people are having. I hope they can get this stuff figured out.
    Thanks again for your help

    Hey guys, i am living in purmerend the netherlands and my ph2 went after upgrading to the left in gps mode as well. In attitude mode it worked much better. So thanks for the software to downgrade to 1.08. My question here is, is the rc downgraded also. As i only am connected to the plane with usb . The software tells me that it was succesful but i like to make sure i am not forgetting anything before flight. I had to many crashes allready. Thanks for replying Ronald

    Thanks for the info. It just confirms there are some serious issues with versions 2.0 and 3.0 as so many reports are coming in like this.

    It's annoying for any if us wanting to upgrade to a H3-3D when it finally gets released. Hopefully DJI is working hard to get this sorted. The fact they are now offering v2.0 and v.3.0 is not very reassuring and no doubt only adds to the confusion for many users.

    There is a rep on here somewhere, we should make sure he is aware of these issues asap.

    Re: Frimware Updates - Lessons Learned - 1.08 vs Anything El

    I'm going to try and revert to 1.8 tonight. Question, when I go to calibrate the compass afterwards, is there a good way to disconnect the gimbal during the vertical and horizontal rotation process. My HD-2D & gopro will hit the anti-vib mount if I get the phantom turned to sideways. What's the best way to do this?

    downgraded to 1.08…got it out today and did a little flying. finally got a day with light wind…definitely better than 3.0…felt way more confident…held altitude perfect, no dropping…did get TBE and j hook at first but then it settled down after a few minutes…Im a newbie here but I would def recommend downgrading from 3.0 until they fix all the issues…I hope they can get this TBE and J-hook fixed because with it taking a few minutes to settle down, those are precious minutes wasted
