You don't have to be rooted and the image is good. In Windows,. I used fastboot command as follows: fastboot flash super C:\super.img and it seems like nothing is happening but give it a minute. It started flashing 35 files one at a time. Worked very well for me

Ok, my mistake. Flashed without error but now tablet starts automatically on fastboot mode and doesnt boot into user interface. Tried with dotos and some stock firmware. Any ideas?

u need to recover full os. reflash dotos super using mtkclient

first erase super partition and re write super using mtkclient (u need to rename super.img to super.bin)
