Ensure the bootloader is unlocked, or supply an authentic secure Auth File ( .auth ) if it is a modern secure chip.

Working with low-level trace modes gives you deeper access to your device, but it also carries risks. Keep these best practices in mind:
Before we dive into Runtime Trace Mode, let’s establish a baseline. The Smart Phone Flash Tool (SP Flash Tool) is a Windows-based utility designed to read and write firmware (ROM) to devices powered by MediaTek processors. Unlike Qualcomm’s QPST or Samsung’s Odin, SP Flash Tool offers low-level access to NAND flash memory, including preloader, bootloader, and NVRAM partitions. : Navigate to Options > Download and enable
If you are using an MTK Bypass utility to bypass secure boot protection alongside SP Flash Tool, make sure the LibUSB Win32 filter is properly mapped to the specific boot port.
Tracks the precise memory offsets where the scatter file partitions are being burned.

A "Not Acknowledged" (NACK) message indicates that the computer sent data, but the mobile device's flash memory chip refused to write it. This often points to a locked bootloader or a failing physical memory chip. Crucial Safety Tips for Advanced Flashing Enabling Runtime Trace Mode (v480 and above) Ensure
Do not flash the preloader file or use the "Format" option unless absolutely necessary, as it can make the device unbootable.
The process for version 4.8.0 follows the standard MTK flashing workflow with the addition of trace logging: Smartphone Flash Tool (runtime Trace Mode) - Facebook
