The Neon VFD 320 is a relatively new device running the Android 8.1 Go version. The device spots a secure boot MTK chip and flashing or unlocking is impossible without its DA file.
In this post you’ll find the DA File necessary to work on your device be it, unlocking, FRP Bypass, IMEI repair. I have gone a step further and provided the device’s scatter file should you need to use.
The DA file linked in this article was tested on SP Flash Tool but go ahead and try it on your favorite flashing tool.
