Archive of about 1.91 MB containing firmware for the TD-8811 modem, hardware revision 2.2. Nothing else is stated in the name, so check inside whether it is a full flash image or an update file meant for the web interface. A bricked unit that no longer boots is normally recovered by reading and rewriting its SPI flash chip with an external programmer. Before writing, confirm the version printed on the label under the device, compare the image size with the chip capacity and save the existing contents as a fallback.
