Upgrade Zenfone 3 from Android 7 to 8

[Tinkerer]

Hi There,

Having a few issues with the forum so plse ignore any posts with just a subject heading. I'm wondering if its possible to upgrade my Asus Zenfone Z01HD from Android 7.1.1 to Android 8. I need the latter for access to banking apps, etc.

If anyone know if and how this can be done that would be much appreciated.

Unfortunately, the ZE553KL is an earlier model and has now ceased to receive maintenance and updates.
If you have a need for a system upgrade across versions, we recommend visiting a service center where our staff can assist you.
