Hello,
I just bought an Asus ROG ZS600KL 8G/512G phone and I would like to update to Android 9.
I am currently on Android 8.1.0 with security update from october 1st 2018. When I check a new update (as descibed in Asus's page), it tells me that my system is up to date when this is obviously not the case !
Here are some details about my configaration
Please tell us some basic information before asking for help
Model Name: ROG phone ZS600KL 8G/512G - ASUS_Z01QD
Firmware Version: build OPM1.171019.026.WW_phone-15.1618.1810.77
Rooted or not: not rooted
Shall I use manual installation
I've seen here :
sorry, i can't post this asus link to download updates
that there are many updates available.
Please help.
Sincerley yours

Hi diouky666,
Since your current version and the latest version are on different Android systems, to ensure normal update, we suggest that you manually update to the latest firmware version by following the order below:
WW-15.1630.1907.98>WW-16.0410.1910.91>WW-16.0420.1912.16
You may find & download the firmware file here:
ROG Phone BIOS & FIRMWARE | Phone | ASUS GlobalHow to update firmware on my phone? | Official Support | ASUS Global
We suggest that you backup your data before updating. Thank you and have a nice day 🙂

Thank You Y_ASUS.
I've tried yesterday without success a manual installation but my mistake was to start from WW-16.0410.1910.91 or WW-16.0420.1912.16
I've made what you suggested (WW-15.1630.1907.98>WW-16.0410.1910.91>WW-16.0420.1912.16) and now it works !
Many thanks again and have a nice day
