The Solution (I’m not responsible if you break your tablet or doesn’t work for you): Finally I couldn’t wait so I opened the tablet and fixed it, how? let me explain for everyone who has same issue
After checking by HDMI that the tablet is working you have to shut it down and then remove the screws with a pentalobe screwdriver
Tnx for the instructions Jorge. What size pentalobe is the correct one and where did you buy it?
