Lenovo IdeaPad 5 14ITL05 (GLMS1 la - k321p )

Hello everybody!
I made some repairs to this board and had to replace the EC KB9052Q, Ci's.. UT1, U7,U9, UA1. The board no longer shows shorts, however, when connecting the power supply (USB_C), I only find +TCP0_VBUS(+5V. I have a question??
As for KB9052Q, there is a need to write a BIOS directly on it, or just check the integrity of UC2 and UC4, could anyone help me?
I didn't find anything about writing direct .BIN to KB9052Q on this model, although it is writable.

Already resolved! I downloaded the KB9052Q BIOS. I'm just getting caught because I don't find this one in the list of my recorder that I recently acquired (RT809H)..Still catching it....
