i want to test your GSI Image on an older Smartphone Samsung Galaxy Xcover 3. I am a Beginner concerning installation of custom ROMs to Smartphones. My Problem is, that my Testphone doesn´t support fastboot. Samsung is using Download Mode instead. Is it possible to flash the gsi image with the Odin Utility from Samsung or is there a way to get fastboot working on the phone?
Both Xcover3 models do not fulfill the requirements with stock Android 5.0 (Lollipop) or Android 6.0 (Marshmallow) by far, as they are not GSI Treble compliant. So - no chance of getting any GSI to work.
