Zip archive with firmware for the Realtek RTS5452H USB-C controller at position U27, from a WIN4 device with the 6800U CPU variant, carrying CRC32 0xF822AA32. It pairs with images for other designators, as each Type-C controller on the board holds its own code. Technicians use it to restore a port that no longer charges or negotiates power after corruption. Back up the original flash, write this image with an SPI programmer and verify the checksum. Check you are targeting U27 and not another controller position.
