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). It's 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 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. 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 ) .
How do I use an Alcatel custom Secure Boot DA file?
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.
Important Notice
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
If your model is not on the list below, you can check the collection list and try each item one after the other, hopefully, one will work for your device and if anyone eventually works, do let us know by replying on this thread with the exact name of the file that worked and your phone model
