@savalizz: So far here is no special ROM for the Mi 9 Lite, unless the ROM for the Mi CC9 (pyxis) also fits the Mi 9 Lite. For the Redmi K20 and Mi 9T this is the case - one ROM for both units (davinci). Maybe one of the devs can confirm this?
Edit: Maybe you can try to find out the codename of your device with an app like Material Terminal, Android Terminal Emulator, AIDA 64 or Droid Info.
Ah, ok, I didn't look in the download section, because the ROM for my Mi 9T isn't ready yet. Now I saw it - one Rom for both devices. Only the table isn't yet updated.
