Unless you're SURE it's a Chicony webcam, I'd be concerned you flashed the firmware of the wrong camera and now you've got a brick instead of a webcam. Notebook manufactures often use more than one webcam vendor in the same model (line).
Firmware is a one-way street, there's no way to uninstall or remove firmware. You might be able to flash the proper firmware over-top, but usually once you flash the wrong firmware, the device is done-for (as there's then no way to communicate with the hardware to flash the 'right' firmware).
Although I suspect it may be too late, you can figure out which webcam hardware your notebook manufacturer used, and then in turn figure out what firmware/drivers you need by following a guide like this TechSpot one: How to identify your webcam (and then find its driver).
I realize this is WAY late, but if what Ƭᴇcʜιᴇ007 postulates is accurate, namely that the camera is now a 'brick' due to having been flashed with incorrect firmware, the first place to try in searching for the correct firmware would be from the manufacturer's website.
Note: The question poster stated in comments "I think I changed the firmware for webcam" and when Ƭᴇcʜιᴇ007 asked "Exactly which make/model of the notebook? What's the make/model of the embedded camera? Exactly which Firmware did you flash?" they replied with "notebook msi ex623 , with tool Chicony Firmware Tool v.3.0.2 -, firmware update CKF7010 firmware 6322."
If the Alex is still having this issue, or if any others make the same mistake, I hope this will prove useful in recovering the functionality of their laptop's webcam.
