If you’re working with Vivo PD1901 and face secure boot errors during flashing or unlocking, you’ll need a special tool — the DA Auth File. DA stands for Download Agent, and it’s essential for bypassing the secure boot on many MediaTek-powered devices. Without it, your software flashing tools won’t be able to communicate properly with the phone.
The DA file acts like a key to unlock access for tasks such as removing FRP, repairing IMEI, fixing boot loops, or flashing firmware. Whether you're using SP Flash Tool or another GSM utility, a compatible DA file like the one for Vivo PD1901 ensures a safe and smooth operation.
