BLU MTK Secure Boot Download Agent (DA) loader files
This thread is dedicated to listing BLU Download Agents (DA) files. Before now, we only listed them at the model’s component files thread so this thread will be updated too to make it easier for members to find.
This is a community effort so the files are free, no passwords. If you have any confirmed DA that’s not listed below then help this list grow by sending it to us.
Why do I need a custom Download Agent (DA)?
As Mediatek’s chip security has evolved, we have seen an increased complexity in flashing firmware (like -sign.img & Secure Boot). Its no more (always) as easy as just loading a scatter file and flashing using SP flash tool. DAs are strategic following the increase in the need for boxes and dongles to perform tasks; even in the use of the SP Flash Tool to bypass Factory Reset Protection (FRP).
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 (these dates as far back as the BLU 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.
- Do not format devices with secure boot or flash using the 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
