Help with Downgrading Android 13 to 12

Star I

Hello, looking for some help on how to downgrade Android 13 to 12 for Zenfone 8. I have downloaded the firmware provided in another thread and have tried to follow the ASUS steps here:

However, I am required to open an "update_image.bat" file which doesn't exist in the zipfile provided by other users in this thread:

Like others, this is because I am unable to pair my Zenfone 8 to wearables (Whoop in my case) which upon reading seems to have been an issue since the Android 13 update some time ago.

Many thanks for any help!
