My webcam doesn't work, I installed the camera driver. Camera option in Skype:
I closed all programs but camera not work
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).
