Hi All,
I successfully installed AOSP Oreo 8.1 system image on whyred, thanks to treble. It successfully booted and all the things are working fine till now. Here is the screenshot of the device info:
Steps to do the same:
1)Unlock Bootloader!
2) Flash Miui 9 China 8.1 Fastboot Rom from the link below(instructions available on Miui website):
http://bigota.d.miui.com/V9.5.4.0.O...EICNFA_20180308.0000.00_8.1_cn_c2879bfe3a.tgz
3) Boot and setup the rom just to make sure.
4) Now, download the AOSP Oreo 8.1 system.img, from the link below. You have 2 options, either download the img with gapps and su included or without them, your choice. I went for option a). (Thanks to @phhusson for the system imgs)
a) system.img for A-only ARM64 devices with GApps and SU:
https://androidfilehost.com/?fid=962187416754465917
b) system.img for A-only ARM64 devices vanilla:
https://androidfilehost.com/?fid=962187416754465916
5) Replace the system.img in the fastboot rom downloaded in step 2 with the system.img downloaded in step 4. Now, flash the rom as you did in step 2.
6) Your phone will automatically reboot after successful flashing.
7) Enjoy AOSP Oreo 8.1 :highfive:

Bugs:
1) Screen doesn't wake up using power button after devices sleeps.
Solution: Turn off 'Jump to Camera' from gestures settings.
2) Lowest brightness setting is not low enough.
3) No voice in-call
