New to the forum and to Indy

I recently moved my setup to Stellarmate/Ekos.
I found that my guide camera, despite being recognized, does not work under Ekos due to the specific non standard setup of USB
The camera still works fine under Windows.

Research points to this forum where some people flashed the camera firmware with a different firmware provided by ZWO (asi120mm-compatible.iic)

Now, the flashing tool is still on ZWO web site, but the firmware is no longer there (at least I am unable to find)

Does anyone have a copy ? where can I download it ?

best regards
