The stone the builders neglected has become the cornerstone. That’s how best I can summarize the DA file crisis we now face.<\/p>\n
You’d probably not really noticed the Download-Agent section in your favorite Mediatek (MTK) flash tool but with the way things are going, its becoming a critical determinant of whether or not whatever you’re trying to do halts abruptly or proceeds.<\/p>\n
DA is an abbreviation of Download Agent. The DA is what enables whatever Mediatek tool you’re using read or write to the device in Flash Mode (powered off and sometimes holding volume buttons).<\/p>\n
A Mediatek device which has Secure Boot won’t allow any tool read from or write to it without a custom DA file loaded to the tool. In other words, no backup, flash, FRP, IMEI write etc without a custom DA. A DA file is thus like a key and the Scatter file like a map.<\/p>\n
The Secure Boot issue has been around for a while (my earliest encounters were with Tecno M3S & Acer B1-770; both Lollipop devices) and has increasingly been adopted in Mediatek devices. When trying to interact with a Secure Boot MTK smartphone without the required DA file, you might encounter errors like:<\/p>\n
…and the list goes on. For such devices, you’ll need a DA file.<\/p>\n
When handling a Secure Boot MTK device, these are some things you should have at the back of your mind:<\/p>\n
Team Hovatek started a Mediatek (MTK) Secure Boot DA file collection<\/a>. We’ll keep updating the list. Its a community effort so please don’t leave all the work to us. Send us any confirmed DA file not on our list and it could help someone.<\/p>\n We’d dropped a video explaining how to load the DA file in SP Flash tool<\/a>, NCK box<\/a> and Infinity CM2 box<\/a>.<\/p>\nHow do I use the DA file after downloading it?<\/h4>\n
