P-660RU-T1v3s

BIOS .zip 230 B Shared

ZIP labelled for the ZyXEL P-660RU-T1 v3s ADSL modem, but only 230 bytes in size, too small to contain any real firmware image. It most likely holds a text note, a link or nothing useful, so open it and treat it as a placeholder. For the actual firmware, a separate full-size package for this hardware revision is required. When flashing, make sure the revision on the device label reads v3s, use the web interface or recovery mode, and keep power stable until the modem restarts.
