Tested BIOS images for the Hellcat 17 TGL 8-layer mainboard, Wistron number 19829-1, offered in 8 MB and 16 MB versions inside a 9.94 MB RAR. Tiger Lake boards may use different flash sizes, so choose the image that matches the capacity of the SPI chip fitted. Read and save the original contents first, verify the board number on the PCB, and write with an external programmer to recover a dead or looping laptop.
