A Download Agent (DA) enables your favorite Mediatek Flash Tool to read and write to the device. In a case where the default DA can’t, you’ll encounter constant errors or the phone just powering up when you connect (this dates as far back as the Tecno M3S & P5S). This is where a custom DA file comes in. Depending on the tool you’re using, you manually load the custom DA ( MTK_AllInOne_DA_SP.bin or DA_SWSEC.bin ) .
After you’ve downloaded and extracted the bin file, you rename the file to MTK_AllInOne_DA_SP.bin or DA_SWSEC.bin (depending on what you downloaded). At this point, you either manually load the DA in the flash tool you are using or replace the tool’s default Download Agent with the custom DA then relaunch the tool. To learn how to use / load a DA file in several Mediatek flash tools, see the guide on how to use a secure boot DA file for Mediatek devices.
- Do not format devices with secure boot or flash using firmware upgrade
- 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
