Can't update Zwift Hub firmware in Companion app [Android and iOS]

Hi @shooj you moved my thread to a resolved thread. As this is closed I cannot interact with anybody. I have created this new thread as I do not know how to send private messages in this forum…

I already followed steps and cannot make it work. Location services are activated and not paired by bluetooth or Zwift app (today is on maintenance so this is not a problem).

I have a Samsung S9+ and Android 10).

I have recorded a video of the process, but cannot include any link on the post…

Unfortunately I can’t help you on your update issue but I can provide you infos about Links and PM: you have access to that only when you have reached the “member” status (trust level 2), that’s why you can’t do that for now…

I hope you can get your issue sorted though!

Hub is not paired with phone, just with app.

As someone from Zwift team recommended by e-mail…I have also tested trying with airplane mode and wifi/bluetooth enabled, disabling 5g. But same result.

I think it has to do with the app, because in the process it can connect but stucks at bootloader…I have latest version from 12 october.

Resolved! Tried in another device and worked…Seems mine has some security configuration that prevents upgrade.

Thanks for letting us know, and glad that it’s working on a different device.

I am curious, though: is that Samsung a work-issued phone? What do you think is the security configuration blocking the app?

I think it may be my company security policies, as it has some firewall installed

Didnt work

I did the new software update and now the hub connects to Bluetooth but no signal is sent and blue light blinks slowly and Zwift doesn’t have an answer.

Hi @Kevin_Warshel, welcome to the forums!

Did you update the trainer firmware, or are you talking about the latest version of the Zwift game app?

I updated the hub

I can get it to work through the companion app but the Hub shows Bluetooth connected and ANT not working when I just use the computer without the companion app.

I updated the Zwift Hub trainer and now I can only use the trainer with the companion app. The ANT+ shows a problem.

unfortunately there are many reports similar to yours over in this thread:

You may want to contact Zwift support

thanks for the info it’s much appreciated.

Hi everyone,

after assembling my brand new Zwift Hub trainer I followed the setup guide and tried to make a firmware update with the iOS Companion app. After starting the update process on the Companion app, either the app or the trainer crashed.
The trainer is now showing the red LED, when opening the “Zwift Hardware” section in the Companion app the LED switches to a steady blue, but the Hub can’t be found by the app. Trainer switches back to red LED after a while.
I also tried to use another iPhone and turned Bluetooth off on mine, but to no avail.

Is there any hard reset or similar on the Zwift Hub? Has anyone else encountered the same issue? Or are there any other recommendations how to proceed?
I’d really love to start zwifting…

Best,
Tim
