By the ZycleDFU you should get 3.25 because the firmware file ia in the download and that is 3.25!?
Does the cmd find yuor bkool and forcing it in DFU mode and then uploads firmware to it? 
You can check version with bkool toolkit app to your phone 
Your welcome
Helped taking out the usb-hub - no idea why.
Thanks a bunch

No problem, sent you the link. I don’t know what the current version of the Bkool software is up to now so if you get it to work please post the version number for anyone else who needs it.
HI,
I have a bkool smart pro (black one), I can’t connect it with ant+. I tried to install an old version of the bkool software, but i can’t connect to it without accepting the update.
Is there any solution so that i can connect my bkool as a smart trainer ?
Thanks

@Sandy_Thomson Thank you so much for the links, really kind of you, however I am having the same problem as a previous thread, when trying to login it says “error connecting to multiplayer server”, Tried to go offline but no sucess.
Has anyone found a solution to this??? @Kim_Pedersen1

Hi, yes I found some Italien website, where someone wrote some code that did the job. Unfortunately I don’t have the link, but try and google it, thats what I did.
Hola @Sandy_Thomson podrías enviarme el enlace para windows porfavor?
Muchísimas gracias amigo!

Hi guys.
I have a bkool smart pro1 trainer, and I think I have the same problem, where i can’t connect ‘controllable’ on zwift. I use a Macbook Air, with Ant+.
The setup works fine with the same ant+ device, and Mac on my other trainer - Tacx Neo 2t.
Do I need the old software version? - where can i download it? 
@Sandy_Thomson maby you can help with a mac link?
The firmware version is 3.16 - the latest.
Sure, I’ll send you the link, but I haven’t heard of anyone getting it to work correctly recently.
Hi, could you please pm the version:
the Bkool Cycling software old version (v3.53)
All links dont wirk anymore.
Thx
Daniel
Hi Sandy,
I have a Bkool Pro 1 trainer and trying to run it on a apple tv. I can’t find my device under ‘controllable’.
Have tried to download the BkoolTool App to update the firmware but it just keep searching.
Can you help me with any guidance for how I can get it to work?
I don’t believe this method to update the firmware works now. Bkool appear to have closed it off.
