Firmware backup labelled gwtn156-7, with the Spanish word respaldo meaning backup, in a 16 MB raw image. The name gives a model-like code but no brand, board number or chip type, so confirm the hardware before use. A 16 MB file matches a 128 Mbit SPI flash and can restore a device whose firmware got corrupted. Read the current chip first and keep that copy, verify the capacity matches, and check the written data with the programmer afterwards.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Satale_bios_esquemas_Laptop. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
