RAR-packed firmware for a Realtek RTS5452H USB-C PD controller from Compal board LA-M611P. Compal uses the LA-xxxxP pattern, and the number on the PCB should match before you write anything. No checksum or version is given in the name. The image is used to repair laptops that will not charge through Type-C, stay at zero watts or lose USB-C data, by reprogramming the SPI flash next to the controller with a programmer. Dump the original chip first so it can be restored if the new image misbehaves.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosdumpcomputer. Enginerys does not host this file.
