Firmware dump for Toshiba Satellite C55 and C50 series laptops using board 6050A2566201, compressed as a 2.95 MB RAR. The 6050A numbering belongs to Inventec, the ODM that produced many Toshiba boards. Extract the image and program it into the BIOS SPI chip with an external programmer to revive a board with corrupted firmware. As the name covers two models, check the board number silkscreened on the PCB, keep a copy of the original chip data, and make sure the image size matches the flash device.
