How to use an MTK Secure Boot Download Agent (DA) file

This tutorial will explain how to use that DA file you just downloaded for your Mediatek (MTK) device with Secure Boot. You'll need the DA file to backup, flash, bypass Factory Reset Protection (FRP) etc on whatever MTK Flash Tool you're using. This guide covers SP flash tool, NCK Pro Box & Infinity CM2 box.

Important Notice

• Some DA files are tool-specific (i.e will only work with a specific Mediatek tool) so try them on as many Mediatek Flash tools as you can
  
• Only Mediatek devices with Secure Boot require a DA file
