Okay I've downloaded fw tool, chose the correct firmware and upgraded my zwo 120 mc so it will work on usb 3. Seems that this was a mistake cuz ever since camera is not working properly. There are millions of bad pixels now, bad columns, vertical banding and the images coming in are not stable, they seem " flash" somehow. I've checked all the cables and they are working fine.
Is there anyone there who can help to check what the problem is ? Or maybe to help me rollback to native firmware?
