Firmware package named only Q35T-AM, a model or board code with no brand, revision or chip details given. It is a 1.80 MB RAR archive, so unpack it to identify the image and any accompanying files. A dump like this is typically written to the SPI flash with an external programmer to recover a board with damaged firmware. Confirm the board code on the PCB matches, make a full backup of the existing chip, and verify the image size against the flash chip before writing.
