How to Flash LineageOS on Xiaomi Mi 8

Hi, I installed LineageOS again. This is very very important:

1) flash official MIUI 10 .tgz with MiFlash Tool (lock device)

2) unlock device via MiFlash Unlock

3) flash TWRP (NOT THIS) > only this version

4) Wipe all under "Advanced Wipe"

5) "Format Data"

6) reboot to recovery

7) copy and flash lineage-15.1-20180928-UNOFFICIAL-dipper.zip

8.1) copy and install Open GApps Full or lower

8.2) alternative 1: use Open Gapps Stock and add the following configuration to your Mi 8 > /sdcard/Open-GApps/gapps-config.txt

Exclude
DialerGoogle # Skip Google Dialer

8.3) alternative 2 (Pixel feeling without some apps): use Open Gapps Stock and add the following configuration to your Mi 8 > /sdcard/Open-GApps/gapps-config.txt

[MENTION=6002018]Ninnix96[/MENTION]: Very nice rom. Now the Xiaomi Mi 8 is like my old Google Pixel XL. Thank you again :). The Open GApps Google stock camera run without problems too.
