Mtk-allinone-da.bin
Meaning: The preloader is refusing to set up external RAM for the DA. Solution: Boot into BROM mode (not preloader) by shorting CLK to GND on the eMMC. The DA will load into SRAM only.
Older MediaTek tools used separate DA files for different chipsets (e.g., MT6575_Android_scatter.txt DA or MT6582_Android_scatter.txt DA). The mtk-allinone-da.bin is a unified, modern DA file that contains protocol handlers for nearly all MediaTek architectures up to MT6893 and beyond. It automatically detects the chipset and adapts its instructions. mtk-allinone-da.bin

While the All-In-One DA is the standard, you have alternatives. Meaning: The preloader is refusing to set up

If you flashed the wrong boot image or corrupted the preloader, the device won’t turn on. Using SP Flash Tool with a proper DA can overwrite the corrupted partitions because the DA bypasses the main boot flow.
