Warning 2: Adjusting the fan speed of U58/H56 at will may cause failure to the system, please operate with caution. If the system crashes, please reinstall Windows 11 (which can be downloaded from our official website).

ITE_WinECU_I2EC_v2.3.1.exe

1. Download ITE_WinECU_I2EC_v2.3.1.exe and run the installation on your desktop.
2. First write 01 in the 0x02f1, and then write the rotation speed (0x00~0xb7) in the 0x1805 position, corresponding to 0~100%.

I followed the steps exactly, the fan does accept my input from step 6, but it immediately goes back to factory setting. How do I make it permanent? I am using the BIOS from https://forum.alliwava.com/threads/alliwava-u58-ryzen-7-5800u-ami-bios.27/ with default settings.

We will update and release a version of BIOS that integrates 3 power consumption options (high, medium and low), corresponding to the appropriate fan speed.

Step1. Download and update the EC File.
Step2. Download and update the BIOS.
Add three modes to the new BIOS page, corresponding to different fan speed.

EC File: EC-ACB20-0.17-GRTID
BIOS: ACB20_1.01_GRT_20240521

Can you please explain in detail how to update the EC file? As far as I read the file must be extracted to a USB flash drive, however the procedure differentiates between the vendors.
Also can you please explain how to update the provided BIOS after that, because the zip doesn't have a .bat-file to start the installation like the unlocked BIOS provided in the thread https://forum.alliwava.com/threads/alliwava-u58-ryzen-7-5800u-ami-bios.27/
