If you find Android Oreo is buggy or you want to return to stock ROM, follow these steps:

Make sure you’ve backed up all of your IMPORTANT DATA before downgrading/returning to stock ROM.

I am not responsible for bricked devices and dead SD cards. YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

1) Download Nougat RAW firmware here:
ZE520KL: Link
ZE552KL: Link

2) Download ASUS Flash Tool here: Link

3) Install ASUS Flash Tool

4) Now, power off your device and enter Fastboot mode by pressing Power Button + Volume Up button

5) Open ASUS Flash Tool and select your device

6) Select the RAW firmware you've downloaded

7) Click on the Serial Number of your device.

8) Click Start and wait 5-10 minutes

9) Congratulations, you have downgraded/returned to stock Nougat ROM

Well, anyone done?
I'm seriously thinking about doing it because Oreo here did not work out.
