Firmware image from a Winbond W25Q64BV, a 64 Mbit (8 MB) SPI flash, for a device labelled 15-G3, in a 4.33 MB zip. No brand or board number is given. Boards that carry both 8 MB and 16 MB chips split the firmware, and a matching W25Q128BV dump for 15-G3 is listed separately. Program it with an SPI programmer only after verifying the model and saving the original contents, and ensure the extracted image is exactly 8 MB.
