- February 26, 2025 · calculated by us from the maker’s dataHow I calculated it: ASUS’s firmware page for this model says it reached end of life and its firmware will no longer be updated, next to the final firmware 3.0.0.4.386_48322. ASUS gives no separate date, so we use that final firmware’s release date (2025-02-26).
