So, that is the problem. I tried to search at google but no luck, only responses were boot.img, and those are not the same. updater-script:
assert(package_extract_file("boot.img", "/tmp/boot.img"), write_raw_image("/tmp/boot.img", "boot"), delete("/tmp/boot.img")); set_oemsbl_size(494552); assert(package_extract_file("oemsbl.mbn", "/tmp/oemsbl2.img"), write_raw_image("/tmp/oemsbl2.img", "oemsbl2"), delete("/tmp/oemsbl2.img")); assert(package_extract_file("amss.mbn", "/tmp/amss.img"), write_raw_image("/tmp/amss.img", "amss"), delete("/tmp/amss.img")); assert(package_extract_file("splash.img", "/tmp/splash.img"), write_raw_image("/tmp/splash.img", "splash"), delete("/tmp/splash.img")); set_appsbl_size(66328); assert(package_extract_file("appsboot.mbn", "/tmp/appsbl.img"), write_raw_image("/tmp/appsbl.img", "appsbl"), delete("/tmp/appsbl.img"));
