Snagflash already supports flashing Android sparse images. However, users currently need to convert raw images to sparse format using an external tool before flashing when the image size exceeds the target's Fastboot download limit (e.g. U-Boot's max download size). To simplify the workflow, automatically convert raw images to Android sparse format during flashing and stream them as multiple sparse chunks. This allows large images to be flashed successfully without requiring the full image to fit within the target's download buffer and eliminates the need for an external sparse conversion step.
