BIOS package for the Lenovo IdeaPad 330S-15ARR, the AMD Ryzen based 15-inch model, carrying firmware version 7WCN30WW (marked V06 in the name). Lenovo firmware versions follow this pattern of a project code plus build number, which helps confirm that a dump belongs to the right machine. It suits recovering a corrupted or bricked BIOS by reprogramming the SPI chip with an external programmer. Read and save the original chip contents first, and verify that the image size equals the flash capacity before flashing.
