No no. You reflashed the correct one = USB C Rom. It is used to define the code for the ACE conrollers from TI (CD3215). The firmware you downloaded is the correct one for the same flash device. Since you have 20V contracts being selected - all is ok.
My bad reference earlier to the part being called for the T2 ROM.
The T2 ROM is another device on this logic board which demands a different firmware to be loaded. Perhaps that component also needs to be reflashed but not sure if this forum has the dumps posted. There is a tool from Aliexpress that has the dumps but a proper socket or PCB with a proper voltage (level shifter) can program the device as well.
For now...
Confirm the voltages on that device but you may have to probe elsewhere on the PCB to measure each leg.
