ROG PHONE 5 Won't Update Into UL-ASUS_I005_1-ASUS-18.0840.2202.231-1.1.103-user.zip
Because .231 firmware was for a11 but you have a12
You can try update to .67 for a12
I already mentioned this in my discussion: the .231 update is for Android 11 only
My English is really that bad?
18 = Firmware for Android 11
31 = Firmware for Android 12
@juan_mario_07 Please refer to the UL file called "Version Android 12 to Android 11".
ROG Phone 5 (ZS673KS) Software downgrade from Android 12 to target Image Version: WW-18.0840.2201.226 (Android 11) for WW/EU/RU versions.
