Many MediaTek devices come with a secured boot/boot ROM that can not be modified or controlled with normal DA agents (Download agents). For new Chuwi devices, you will encounter authentication or buffer errors while flashing any ROM or IMG files using Chinese flash tools. For such devices, you need to use a custom secure Boot DA file which can bypass this error. So today, in this article, we will give you links to download latest Chuwi MTK secure Boot Download Agent loader files which will work with SP flash tools.
What are Download Agent Files?
These files are commonly known by the name of DA files. They play a major role in flashing any file into a MTK device/system. These DA files are needed to access the device to backup, flash, bypass Factory Reset protection (FRP lock) etc. using an MTK flash tool like SP flash tool.
However, new MediaTek devices like Chuwi devices comes with a secure boot system which cannot be bypassed with normal MTK DA files. For such devices, we need to use a custom secure Boot DA file.
Advantages of MTK Secure boot download Agent loader files

And then you can perform the following functions:
- Bypassing Factory Reset Protection (FRP lock) system
