The V6 revision often includes updated chipsets or memory configurations that differ from earlier models. Hence, Tenda maintains a separate firmware branch specifically for this hardware.
Tenda’s official support site historically provided firmware for the F3, but as of 2024–2025, many older product pages are delisted. Still, archives exist: Tenda F3 V6 Firmware
