- Previously, when running, mkboot recovery.img recovery, the second argument can't be stat when attempting to determine it's original size. - I included a file check for the path to properly handle this situation which also allows the ability to unpack an image from a separate directory rather than having the image inside the project directory. - Following commands have been tested to work for the second command argument: mkboot /sdcard/recovery.img recoveryfolder mkboot recovery.img recoveryfolder mkboot ./recovery.img recoveryfolder mkboot ~/sdcard/recovery.img recoveryfolder
