I have been building two flashable zip files in my builds, one for installation via recovery, one for installation via fastboot.
However it seems that the fastboot method cannot be relied on: it failed for @Cooler on aurora (see [here](https://community.iode.tech/t/unofficial-iode-5-builds-for-sony-devices/2807/71?u=petefoth). So I tried on xz2c` and that failed also.
I don’t have the time or resources to test or debug the fastboot installation method, so my builds will in future only support installation via recovery (which is the only installation method supported by LineageOS and LineagOS for microG).
For devices that are officially supported by LineageOS, you can follow the installation instructions from the LineageOS devce-specific wiki pages. My builds will include all needed img files.
For devices not officially supported by LineageOS (e.g.the Sony Yoshino devices) see this post
Installing on Sony XZ1, XZ1 Compact and XZ Premium using recovery, or look in the XDA Forum thread for the unofficial LineageOS build on which my builds are based.
I will take have taken down the -img.zip files used by fastboot for my latest builds at <link removed>
Sorry for the confusion
2026-02-22 edit from @rik: removing link to old LineageOS for microG server download location for iodéOS builds as it is causing issues users when finding this old, inactive link. The new download location is https://iode.lineage.microg.org/ It was changed in January 2026 to enable OTA updates for the L4M hosted unofficial iodéOS builds.
