OK, we need to clarify ourselves why this kind of problem occurred knowing that we possibly flashed a correct firmware.
Android firmwares for MTK chips (MediaTek) consist of different partitions. These partitions are commonly known as Preloader, Recovery, Bootimg, etc. We need to understand that these partitions must be totally accurate. Preloader and many other partitions mostly have suffixes of ".bin" or ".img" extract the flashfile downloaded from any of these MTK devices and you will see how they were packed in a folder.
Dead boot, it is something caused by invalid partition flashed on any devices. In case of Android running under MTK chips, "Preloader" is the very sensitive part. Flashing a wrong 'preloader' and your phone is dead.
