Experimental OS Images for the ASUS Zenfone 8

Introduction

This page lists several Custom ROM images for the ASUS Zenfone 8 that are not official supported by the maintainer of the Custom ROMs.

All images were build by me and successfully installed and booted on my ASUS Zenfone 8.

I have also conducted some successful initial tests with each of these Custom ROMs on the ASUS Zenfone 8, but I have NOT done any in-depth testing of these Custom ROMs.

WARNING Do NOT use the images on productive phones! These OS images should only be used for testing the OS and are not supported in any way. All OS images are build using the certificates that are publicly available in the repositories for the Custom ROMs. Backup ALL data from the phone before installing any of these images! You should have one of the raw OS images for the ASUS Zenfone 8 in order to restore the operating system on the phone from scratch if necessary before using any of these images. You should know how to restore the OS on the ASUS Zenfone 8 from scratch using a raw OS image! You should know how to restore the OS on the ASUS Zenfone 8 in EDL mode. Installing an OS image on the phone should not damage the phone but you never know. I accept no responsibility if your phone becomes nothing more than an expensive doorstop after installing one of these images!

An OrangeFox recovery compiled for the image is also available for download for each Custom ROM. These OrangeFox recovery images allow the access to the files in the partition /data after installing the OS image.

The original TWRP and OrangeFox images for the ASUS Zenfone 8 can not longer be used if one of these images is installed on the phone


There is also a link to the guide with instructions on how to build the OS image for each of the Custom ROMs.


If you want to use one of the images on your production phones, I strongly recommend that you download the source code for the image and compile it yourself.


A list of guides with instructions for compiling various supported and not supported Custom ROMs for the ASUS Zenfone 8 can be found here. These instructions can also be used as template for compiling the Custom ROM for another phone.

General instructions for creating a LineageOS based Custom ROM for a phone that is officially not supported by the Custom ROM can be found here.

To install one of the images, boot the phone from a recovery like TWRP or the LineageOS recovery and install the image via sideload.

It is possible, to "update" most of the LineageOS based OS with another LineageOS based OS without performing a factory reset, e.g "upgrading" crDroid to evolutionX or "upgrading" /e/ to crDroid, as long as the Custom ROM supports local updates.
