Here’s a concise troubleshooting post you can use for forums, social media, or a tech blog: If you are trying to unbrick or flash

Common Causes of the "Download DA 100%" Hang

Wrong or Incompatible Download Agent – The DA file bundled with SP Flash Tool is generic. Many newer or specific MTK chips (e.g., MT6765, MT6785, Dimensity series) require a custom or auth-enabled DA.
USB Driver or Port Issues – Poor connection, loose cable, or legacy USB 3.0 ports causing handshake failures. Also, outdated or incorrect MediaTek USB VCOM drivers.
Preloader Interference – The phone’s preloader pulls the USB port offline after a few seconds if authentication fails. The DA upload succeeds, but the subsequent preloader reset kills the connection.
SLA (Secure Loading Authentication) / DA Auth – Newer MediaTek chips (Helio P60/G90/Dimensity) require an authorized, signed DA. Without it, the phone accepts the DA but won't proceed to flash.
Battery Level or Hardware Fault – Too low battery or a faulty eMMC/UFS storage can cause the flash process to hang at the very first step after DA handoff.

Disconnect battery internally (requires opening the phone) or drain it to 0%.
Connect USB. The phone will get power from USB alone.
Flash immediately.
