Hello

By me was today C421 with same problem - input only 5V. After bootup win with precharged battery was visible problem in device manager - Device UCM-UCSI shows error code.
So i have desoldered rts5455 from donor board (E590), then bios update. After reboot no error in device manager, but still not charging
So i have replaced 6S30A (SN1710033RUKR).
....and now is all fine

Soo i can confirm, that rts5455 from another board is working after "reflash"....
