Please tell us some basic information before asking for help:
Rog 1 support might EOL just like Zenfone 5z at this point
But to be honest Rog 1 was indeed a mess in terms of updates the fact that it got android pie (based on zen ui 6) after months of no clear answers was a surprising event in itself
the fact that rog 2 is getting android 11 is a good indication for future rog phones though
The last update for ROG Phone was released November 2020. There are no plans to release Android 11 for this model.
