Firmware dump for a Winlink WL7030U device, read from a GigaDevice GD25Q64B flash chip according to the name. The GD25Q64B is a 64 Mbit, 8 MB SPI NOR flash, matching the 7.58 MB RAR archive size range. Use it with an SPI programmer to restore a unit with corrupted firmware that no longer boots. Verify the chip marking on your board is the same part, read and back up the existing contents first, and confirm the image size equals the 8 MB capacity before writing.
