I cannot update my Sigma 30mm 1.4 copy from v02 to v03.

I have downloaded the installer from Sigma's site: Update_SigmaC30F14V3.exe connected the camera with the lens installed to the PC and followed the on-screen steps.

The update was transferred onto the camera and on the display it showed the Updating lens message.

But the progress bar remained empty even after 20 minutes.

I have tried to update from two different windows machines (10 and 8) but to no avail.

Do you have any suggestions that I might try? (Other than contacting the seller for warranty)


Exactly same issue here. I think I have tried everything, including updating it with different camera body which updated another copy of the same lens OK. So now I contacted seller for warranty.
