Yes, but it's recommended to wipe the system partition ( fastboot erase system ) before flashing the new image to avoid conflicts. Some users have successfully dirty‑flashed without losing apps or settings.

You need a PC with the Android SDK Platform-Tools installed.

This method is ideal for testing the Roar GSI before committing to a permanent flash.

: This component refers to the partition scheme of the device. Android devices traditionally used a single partition scheme (often referred to as "a" or "active"), but with the advent of A/B partition schemes (labeled as "ab"), devices can now have two sets of partitions (A and B), allowing for seamless updates without rebooting into a recovery mode. This enhances the device's reliability and reduces the risk of bricking during updates. system-roar-arm64-ab-vndklite-gapps.img.xz

Because of this separation, you can theoretically take a generic, unaltered copy of Android (a , or GSI ) and flash it directly onto the system partition of any Treble-compliant phone. The generic OS will seamlessly communicate with the existing vendor partition, allowing your phone to boot a completely new OS without a device-specific custom ROM. Prerequisites Before Flashing

: .img is the raw partition image file required by fastboot interfaces. The .xz extension means it has been compressed using high-ratio XZ compression to reduce the download size to roughly 880 MB.
