The download link has been removed from the Download Center due to the "no sound on the other end while calling" bug. You can fix it by disabling "OK Google detection" in Google Assistant settings.
There is still a few severe bugs, for instance no data transmittion for NFC, annoying vibrations, lack of ZenUI apps and features, etc.
This is a beta build, proceed at your own risk. This update will completely wipe your phone's data. Further Android Q updates are not guaranteed.https://dlcdnets.asus.com/pub/ASUS/ZenFone/ZE620KL/UL-ASUS_X00QD-ASUS-AOSP-17.0615.2003.20-1.1.1-use...Link

ASUS ZenFone 5 ZE620KL Android 10 AOSP Software Image Beta Version for WW SKU only*
Please ensure to backup data before upgrade.
*We suggest at least to update to 16.0615.2002.120, then use the UL pack upgrade to Android 10.
Steps of Update:
1.Android 10 AOSP Beta version is now available for download. Please note that this version is "pure" Android system, and will not have ZenUI.
2.Please be aware that installing this system image on a device removes all personal data from the device, so please remember to back up your data first.
3.This is the Android 10 AOSP Beta version, so the user experience will be different from Android P. If you are used to and prefer using ZenUI, we recommend that you continue with the Android P version.
