Code image for a Realtek RTS5455 USB-C PD controller on Lenovo board NM-B911, identified by CRC32 0xC1CD2794. NM-xxxx numbers follow the LCFC pattern used by Lenovo's own ODM. Use it to repair a Type-C port that no longer charges or negotiates power because the controller's flash is corrupted. Write it with a hardware programmer after reading and saving the original chip, and check that the board number and revision on the PCB match.
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.
