Preloader is corrupted or USB drivers are faulty. Fix: Short the test point to force BROM mode, then load the scatter file’s preloader address manually via MTK Client.

| Field | Meaning | |-------|---------| | partition_name | Logical partition name (used in proc/partitions and by-name ). | | linear_start_addr | Byte offset from start of user flash area. | | partition_size | Size in bytes (hex). | | region | Flash region: EMMC_BOOT_1 (bootloader), EMMC_USER (main data), UFS_LUNx for UFS. | | is_download | Whether SP Flash Tool should write this partition. | | file_name | Image file to flash into this partition (if any). |

Because this chip supports both and UFS storage types, the scatter file must precisely define the partitioning scheme. A mismatch (e.g., using an eMMC scatter file on a UFS device) will result in a hard brick.
