I have the Novo 7 venus and worked fine for about a month. Then, the tablet started to get stuck when I was using it. So I had had to keep performing a soft reset for a bunch of times. After this had happened a lot, it started getting stuck in the first loading screens. Obviously, the tablet became useless. So I decided to do the firmware update. I did it and re-did it with many versions but the only thing that changed is that I can use the tablet for 1-2 mins until it stucks again. Any help?
