What is Vivo Y91C DA File
A DA file, also known as a Download Agent file, is a firmware file used by MediaTek-powered devices to help communication between the phone’s firmware and the computer. It is used when flashing firmware or bypassing FRP (Factory Reset Protection) on the device.

What is Vivo Y91C Secure Boot Download Agent File
Many MediaTek (MTK) devices now have a secure boot system in place, which prevents unauthorized access to the internal contents of the chip. To bypass this secure boot lock, special Secure Boot DA files are required. These files provide access to the device’s internal storage, allowing for modification as needed. In order to use these files, a Secure Boot Download Agent (DA) Loader must also be used.
A Download Agent (DA) allows Mediatek Flash Tool to access and make changes to the device. If the default DA is unable to do so, errors may occur or the phone may not power on when connected. This is where a custom DA file can be used. The custom DA file (such as MTK_AllInOne_DA_SP.bin or DA_SWSEC.bin) can be manually loaded depending on the tool being used.
