You can 8.5.10 dowload again, because reuploaded this rom for face unlock added(yesterday)...
Wipe(twrp) or delete(file manager) cust folder but root directory/cust/cust, don't all cust folder.

Exactly. I returned to 8.4.12.
8.4.28 very laggy and phone make reboot.
I don't understand, why it is so slow for global rom?
You prepare and deliver the global rom. Why do you expect to be able to offer a global marketplace device for your software?
I just updated from 8.4.12 to 8.4.28. With twrp. Apn settings no problem, 2 sim ok, 4G ok. The wifi standby settings were not in 8.4.12, not are they now(8.4.28).
You are welcome.
I have no idea about face id.
