Because GSIs use a universal system image, VoLTE or VoWiFi might break. Look for "Phh Treble Settings" in your settings menu to toggle specific vendor patches for your carrier.
: This is the internal release codename utilized by developer phhusson for his Android 11 baseline GSI compilation framework. Subsequent Android iterations use different identifiers (such as "squeak" for Android 12).
Some devices require specific fixes in Phh-Treble Settings (found in your app drawer after booting). Conclusion

system-roar-arm64-ab-vndklite-gapps.img.xz is far more than a random string of characters — it's a complete, ready‑to‑flash Android 11 system image built on the rock‑solid Roar GSI from phhusson. Each component of the name tells you exactly what you're getting:
Let's break this monolithic string into its core components: system | roar | arm64 | ab | vndklite | gapps | .img.xz
You will need a computer with ADB and Fastboot drivers installed.
Understanding system-roar-arm64-ab-vndklite-gapps.img.xz: A Guide to Custom ROMs and GSIs
This is a custom GSI – you will receive official OTA updates. You must manually download and flash newer versions.
Use Magisk with Universal SafetyNet Fix module (though vndklite may require extra tweaks).
Yes, these images come with PHH Superuser built in. You can enable root access by installing the Superuser app or using the built‑in su binary.
Now, let's examine each component in more detail.
Thanks to this separation, GSIs can be developed once and installed on any Treble‑enabled device. The Treble Info app is the easiest way to verify if your device supports GSIs: it will tell you whether your device is Treble compatible and report its partition type (A/B or A‑only).
Using a GSI built for an A/B device on an A-only device can cause boot loops or system instability, as the firmware scripts assume the presence of two slots. Always check your device's partition scheme using the app before proceeding.
