Hi. Do You have downgrade file? If no - You can dowload it from main ASUS site: Smartphones-> Zenfone9-> Support -> Drivers&Software-> Bios&Firmware.

Next step is to put the file direct into main directory of internal storage (no unpacking). In few seconds, phone should return the message that upgrade file is found - if You have backup of data, You can proceed with "upgrade" to lower version.

Which folder or where is main directory of the main storage?
