Cannot upgrade firmware

[yzlisme]

ROG phone 2
Firmware Version: WW_16.0631.1910.35_0
Rooted or not: No
Recently replace motherboard. Used firmware from ROG phone 2 website, tried every WW version from android 9 oldest available to latest available. Whenever restart and prompted to update, click it and it shows "System Update Failed" without any extra explanation. Here's my fingerprint, both bootimage and vendor both WW. Anyone can help?

Well I can't find the above screen anywhere on the app for example like boot count.

There is no .35 version either, are you sure you have ROG 2?

Oh, you have to click "Description" or "Fingerprint" to direct to a new page which is similar to my screenshot.

Yes there is .35 and .44 before reaching .64 as shown in the download page. For some reason Asus remove the older files before .64, all ROG phone 2 update history can be found here https:/www.getdroidtips.com/asus-rog-phone-2-software-update-q-tineline-tracker/

Sounds like changing the motherboard has caused it to lose the integrity between the software and the motherboard. I have taken down the screenshots I have taken now, but the difference was your is showing "orange" state and mine was showing "green" state.
Probably worth going back to the service centre again and let them know about this issue.
