For MT6580 devices running Android 7.0, 8.1, or newer, a Secure Boot DA file is almost mandatory. In the search results, you will see extensive discussions regarding devices like the Infinix Hot 7 X624b and Symphony i75 requiring a "Mediatek Secure Boot DA File" to perform FRP bypass or flashing operations.

The process is a brief one: the tool uploads the DA to the device's volatile memory without modifying any permanent firmware, making it a safe procedure. It is essential for any kind of read or write operation on a MediaTek device. Many MT6580 devices now include a system that rejects any DA file not specifically authorized for that model. To work around this, many technicians employ specialized Secure Boot DA files.
