#1 Asus ROG Strix G513-6050A3249301- MB-A04 (A4) damaged Embedded Controller

I have an Asus ROG Strix- G513IH mainboard G513-6050A3249301-MB-A04 (A4)
The mainboard had an error on the 3V3 rail and a defective embedded controller U301 (IT5571E-128). I fixed the short circuit and also replaced the embedded controller. Now I have a problem with the 3V3 rail. It is not switched.
I have examined the 3V3 and 5V circuits.
The board has a Power Management Controller U8003 (ITE8252E248A) and an Embedded Controller U301 (IT5571E-128). The Embedded Controller is powered by U6100 (RT6575B) via the 3V3 Linear Regulator Output-PIN3. 3V3 are present on the EC.
The RT6575B switches:
1. MOSFETs for the 5V rail on PIN16-UGATE1 the Q6150 and PIN15-LGATE1 the Q6151. 5V are present and always on.
2. MOSFETs for the 3V3 rail on PIN10-UGATE2 the Q6100 and PIN11-LGATE2 the Q6101. However, 3V3 are NOT present. The 3V3 output is activated on PIN6 of the RT6575B. PIN6 of the RT6575B is on PIN84 (ALWAYS_PW_EN3V) of the U301 (IT5571E-128). However, the 3V3 output is not activated by the Embedded Controller.
Does the Embedded Controller need to be programmed? Where can I get a file to program it? I have a SVOD Programmer, but the IT5571E-128 cannot be programmed via the Keyboard-Connector. Only the Power Controller ITE8252E248A (U8003) can be programmed via this.
I hope someone can help me. Thanks in advance!
