Router firmware for the ZyXEL VMG1312-T20 VDSL gateway, build b8 dated 11 May 2018, packed in a 14.3 MB RAR. A technician can use it to restore a unit with corrupted firmware or to bring an older box up to this release. ZyXEL gateways are normally updated through the web interface, while bricked units may need the bootloader recovery or a serial console. Confirm the model and hardware variant on the bottom label, and note any ISP-specific branding, since mismatched images can be rejected or break settings.
