in newer update, ufi failed to create gpt partitioning (repartition)while write firmware in mediatek phones, software shows fake log of create gpt partitioning , writing preloader and set bootcfg.. it only set bootcfg but doesnt create gpt also doesn't write preloader.so it should be repaired.
most of tool nowdays need preloader and gpt inside emmc to write flash. it working well in older versions.
