Updating My Phone
Hi, I am currently the owner of the Asus Zenfone 4 Selfie ZD553KL. Recently I discovered that I can install android version 9 on my phone (currently i have android version 7). But whatever I tried, I could not install the latest android version. I installed the zip file from the official site. I might be possible I tried in the past to unlock the bootloader, but that did not worked. I think this is the issue. I tried several ways to install the zip file, like being in the boot menu, whith fastboot and my pc etc. Does anyone knows a way how to install the latest android version? Cause android version 7 just is not good enough for me.
