Help me with Asus x512u

[Leggga]

Hello everyone. I have a notebook Asus vivobook x512u. I`m new to hackintosh and need some help to fix the touchpad, webcam.
My specs are next : CPU: i3-7020U, RAM: 8 gb, integrated graphics: UHD 620, WIFI: Atheros QCA 9377 (now I use a usb dongle), Audio: Realtek ALC256, BIOS: v303.

There are several problems:
1) Touchpad only works while installing mac OS or boot in safe mode(flag -x).
2) Webcam doesn`t work and shows a black blank screen in apps. In system information webcam detected like USB 2.0 HD UVC WebCam.
3) Brightness control (F4, F5) doesn`t work

What`s works:
1) Integrated graphics uhd 620 (1536mb)
2) Audio and mic with AppleAlc kext
3) HDMI port
4) FN + hotkeys (only F1-mute, F2-decrease vol, F3 - increase vol)

I`ve attached my EFI. Thanks for the help.

Brightness: Use Karabiner-Elements in order to map the keyboard, it works like a charm for me
Touchpad: remove VoodooI2CELAN.kext, leave only the HID driver.
Webcam: I face the same problem, sorry for being unable to resolve it
