And yes I only installed SuperSU(synced from my previous phone) without rooting and when I open it asks if I want to update the binary normally or via twrp/cwm... so it looks like I got a second handed device packed new.
The only problem I'm having is that, the method to switch from CUCC to WW failed and now my phone keeps rebooting itself if I open anything application or settings related and the micro sd is suddenly not detected. I have a huge feeling that reflashing the ROM fresh will fix the problem since I've had so many weird issues like this fixed easily by flashing a stock rom(my previous S3) but sadly so far it doesn't seem like anyone has uploaded a stock zenfone 6 rom.
I also have a question, if you want to update the firmware does the newest update show from the system update at settings? Because mine doesn't, it kept saying I have the latest but I obviously didn't. And correction I didn't have 1.17 but I had the 1.16 version.
To change SKU, have you downgrade to firmware 1.14 first? That firmware is the only one able to be used to change SKU (CMIIW), higher firmware (1.15 and above) will not avail.
