Neo 2 Firmware 0.0.18 Rollback

Firmware Issues

Tacx has released firmware version 0.0.27, and we have received multiple reports from Neo owners that their cadence sensor stopped working after updating the firmware. Specifically, several people requested a firmware rollback to version 0.0.18. We are providing version 0.0.18 as a courtesy, along with the installation instructions below.

Steps To Roll Back Tacx Neo 2 Firmware

BEFORE YOU BEGIN

Take a moment to read our Firmware Update rules, located here. Failure to follow these rules may leave your Neo 2 in an unusable state.

For iOS:

Please make sure you are using Chrome browser. The instructions below will not work with Safari.

  1. Click on the file link above. You should be prompted to download the file.
  2. Tap the “Download” link.
  3. When the file has completed downloading, the link text should convert to “Open in…”
  4. Tap the “Open in…” link, and swipe through the options until you see the “Copy to Tacx utility” icon.
  5. Tap the “Copy to Tacx utility” icon, and the Tacx Utility App will open with the firmware version preloaded.
  6. Connect to your Neo 2 by tapping either the Bluetooth icon, or the circle to the right of your Neo.
  7. Tap the menu icon at the top left of your screen, and choose the Update option.

For Android
  1. Click on the file link above. You should be prompted to download the file.
  2. Tap the “Download” link.
  3. When the file has completed downloading, you may see an option to open it. However, we have had reports that this does not work for all users. If you cannot open the file, open your email on your mobile device, and email the downloaded file to yourself as an attachment. Then, open the file directly from your email. This is due to a flaw in the Android “Files” app on some Android devices.

  5. Connect to your Neo 2 by tapping either the Bluetooth icon, or the circle to the right of your Neo.

  1. The 0.0.27 update resulted in massive vibration and noise when roadfeel was on with my Neo 2. Then the loud grinding noise came rapidly followed by the flywheel seizing. I assume something came loose and jammed the flywheel. Unit is now useless and Garmin told me a replacement won’t ship till October 11. My roadfeel in zwift and the Tacx utility was weak, and getting weaker, hence I hoped the firmware upgrade would help. Unfortunately it made things way worse.

    1. Hi Ian. Sorry to hear you’re having this trouble. Are you certain it was the firmware update, and not something else? By that, I’m wondering why a rollback to .18 or .15 would not have resolved the issue, if it truly was firmware related.

      You are well within your rights to be frustrated by a two week ship date. That’s difficult to accept. May I ask who your retailer was?

  2. I purchased from Excel Sports, but contacted Garmin directly for warranty.
    I assumed as the 60 days were up I needed to contact Tacx, and was routed to Garmin, directly. Excel are excellent so I’m not criticizing them and neither am I criticizing Garmin. Its just frustrating. As soon as I updated to 0.0.27 I tried roadfeel in the Tacx utility and it was massively different. The vibrations were very strong and loud and the whole casing was shaking. It was a huge change from 2 days earlier when I used the trainer with 0.0.18 and it was fine. I was having issues with roadfeel being too weak, in my opinion, in Zwift and the Tacx utility, but as soon as I switched to 0.0.27 it went the opposite way. It may have been that I had an issue with a poorly attached magnet or something that was exacerbated by 0.0.27.

  3. I’m using Chrome on an iPad (13.1.2) and can’t do the rollback from 0.0.27 to 0.0.18. When I download the file there’s no “copy to Tacx utility” icon in the list. I’ve tried all options including uninstalling/reinstalling and rebooting but still no luck. Please advise. Many thanks.

    1. Hi Marshal,
      The problem is that iOS limits the number of “open in” apps that will appear in the list. The “official” solution from Apple is to examine the list of apps that *does* appear, and uninstall those which do not apply. You can always reinstall those apps from the app store. End users do not have control over which apps appear on the “Open in” list, so this is a limitation of iOS that we can’t directly assist you with.

      Here is an example of what you might expect to see on an iOS device with fewer apps cluttering the “open in” list

      1. Hei Drew. I have same the problem as Marshal. I don’t think it is IOS fault that no option for Tacx utility show up when trying to do a firmware rollback. For even when all apps are deleted on my side no utility app shows in the IOS window….

        1. Hi Espen. Thanks for your comment. When you install an app on a device, the app registers itself as being able to open certain file types. That’s how they get into the list. I wish I had more clear information as to why it would not, but according to Apple, it’s that the list is being obscured by other apps. In my own environment, I have not been able to reproduce the behavior; mine always shows on the list (see video comment in previous thread). If it isn’t iOS, I’m not sure what else to suggest.

          The workaround is to download the file, and then email it to yourself, and open the file from your email.

  4. Hi. I have the 0.31 version and have the same problem with the cadence. Suddenly drops to 0. I tried the 0.15 but then nothing worked anymore. So back to 0.31. What can be done?

      1. Okey. But how do I know the new one dont have the same problem? I will contact the store I bought it from. I have not used the utility app, so I do not know if it says overheating, but after a while, no cadence…

        1. Because the symptoms are different.
          Neo 2 – erratic cadence, or zero cadence, ever. Born with firmware version 0.
          Neo 2T – Cadence for a minute or so, and then none. Born with Firmware Version .27
          You can trust us. We are the experts. 🙂

          1. Okey. I will call the store, and tell them about this. So maybe I get a new one. Hopefully one which works nicely.

  5. Hi Drew, my Neo 2 is having a big problem. It loses resistance: red ligth flashes and i get a motor temperature ligth on the utility app (firt one from left to rigth); but I know is not a heating problem bacause it happens even when the device is not in use and cold. My firmware version was 0.0.18 when it begun, I updated to 0.0.32 and problem persist. I my tablet is iPadOS 13.2.3 and with my phone andorid 7.1.1; happens with both devices.
    Thank you for help!

    1. Hi Edgar,
      Unfortunately, when the red light is flashing, it’s never a good sign. It may not be overheating, but something is definitely not working correctly.
      The easiest way to determine why your power LED is flashing is to open Tacx Utility App, and ride with your Neo 2 in the testing dashboard. The testing dashboard will give you very specific information about the condition, and you should try to take a screenshot from your mobile device to provide those details to Tacx / Garmin support. They will be able to assist you further, but there is very little you will be able to diagnose or correct from the consumer side. In all likelihood, you will have to have your Neo 2 replaced.
      I’m sorry you’re having this problem, and I hope it gets resolved very quickly for you.
      -Drew
