Firmware package for a Tenda networking device, identified in the name by the code US_D152_BRV1 and firmware version V2.2.1 in English. The exact retail model is not spelled out, so match the hardware code on the label before use. The RAR archive is about 11.8 MB. Router firmware like this is normally loaded through the web interface or, for a bricked unit, recovery mode or a flash programmer. Flashing an image meant for a different hardware revision can leave the device unbootable, so verify carefully first.
