A: Indirectly. Some antivirus quarantines the DA_SWSEC.bin file, causing the tool to fall back to an older DA. Check your quarantine folder.

If you see MTK_MT6580 , MTK_MT6735 , etc., you need an old SPFT (v3.x). If you see MTK_MT6785 or MTK_MT6893 , you need a recent version (v5.2124 or higher).

The SP Flash Tool is not a universal driver; it is a version-specific client. Each new generation of MediaTek chipsets (from the MT65xx series to the recent Dimensity series) introduces changes to the communication protocol, memory addressing, and secure boot handshake.
