Firmware update issue

[bigb8]

Initially I had an issue with my camera (1MGN), that occured within the last few week. Last week I could stream frames in both VLC and in Python using OpenCV. Today, the camera only returns black frames in OpenCV and in VLC I get an error something like "Camera not providing correct parameters" (translated from Danish).

However, I decided to try and update the firmware. The deletion and Win10 driver installation went succesfully, and the "181112_UpdateFW" tool also provides a "Successful" message when running the write sequence. Regardless of this, the device never appears under camera upon reconnection, the Cypress FX3 bootloader just continues to show up.

I have tried several times, with many different firmware versions, on two different win10 machines and a
win7 machine - all without success

I am clueless as how to proceed - can you guide me on further troubleshooting ?
