Modern MediaTek devices utilize secure boot schemes that require an authorized connection. If the tool fails to authenticate properly, it can break the initialization sequence and throw a RAM exception.
When an eMMC/UFS flash memory chip or the physical RAM chip fails internally due to a short circuit, drops, or age degradation, it becomes "Read-Only" or completely unresponsive to the initialization script. In the repair industry, this is known as a dead memory IC. Fixing this requires professional hardware servicing, involving a motherboard replacement or a highly technical process called "chip reballing."
Ensure the device battery is charged to at least 50%. Alternatively, try flashing with the battery completely disconnected if your device model permits it.
