I have a Hong Kong set which I updated manually using the 1.9 GB FW file via recovery. Google pay then started telling me that I can't make NFC payments due to the software. I suppose ASUS needs to do something to get the FW certified or something? Any idea when that will be completed?
.121 is CTS approved but... some users have reported that they needed to restart their phone to get Gpay working. Some even needed to remove their card, clear the Gpay app and restart. But yes, it will work now.
