Download Oppo F9 / F9 Pro DA File (MTK Secure Boot Auth File)

Here in this article, we’ll be sharing the link to download and install the Oppo F9 / F9 Pro DA File (MTK Secure Boot Auth File). If you don’t know about the DA file, it’s also known as the “Download Agent” file that fixes the device secure boot error on MediaTek chipset-powered models especially. As both the Oppo F9/F9 Pro models are running on the MediaTek Helio P60 SoC out of the box, this MTK secure boot auth file will be required to fix buffer error, authentication error, secure boot error, FRP lock issue, and even corrupted memory issue.

It’s also good to inform you that by using the SP Flash Tool, all the Oppo F9/F9 Pro model users can easily flash the MTK secure boot auth file to bypass or fix the mentioned errors. Alternatively, MediaTek device users can also use NCK Box, or Miracle Box, or Chinese Miracle 2 Box, etc tools instead of using the SP Flash Tool (depends on the user).
