That sounds frustrating! Don't worry, I'm here to help you troubleshoot. Firstly, let's try a simple reset of the camera. You can usually find a reset button or menu option that will restore the camera to its factory settings. This might resolve any issues caused by the firmware update. If resetting doesn't work, it's possible that there's an issue with the new firmware version. Try booting the camera in recovery mode (if available) and see if you can downgrade to a previous firmware version or reflash the old firmware. Another possibility is that there's a problem with the camera's hardware. If none of the above steps work, it might be worth checking for any physical damage, such as loose connections or faulty components. Lastly, if none of these steps resolve the issue, you may need to contact the manufacturer for further assistance or repair. They should be able to provide more specific guidance on how to fix your camera.
