We have to install Via TRWP only? No OTA from updater? Did you clean Data - Cache and Dalvik if it was from TRWP? I dont have computer and not sure how to install it.Just flashed on my Mi8. Everything working amazingly. Much smoother than 8.1 and notification bar higher than notch issue is fixed.
If anyone has any question I'll sure try to help.
Thanks in advance.
