I finally, made it work. I used
Phoenix card, a software that flash 'booteable-auto-intall' images of android.
Before start you need
PhoenixCard 3.06 and a
already confirmed compatible image form your tablet.
1.-The tablet need to be charged for at least 20 min(i plugged the USB cable and connect to PC and it did charge, even when the display doesn't show anything).
2.- Connect the Micro SD to the computer(with already backup your data, because it wipe it all)
3.- Run PhoenixCard.
4.- Select the drive letter where your card is mounted (be careful to select the correct one).
5.- Select the image from your computer with Img File.
6.- Click on Product radio button (already selected but it does need to for the process to work).
7.- Click in Format to Normal(this step is optional, but it doesn't hurt).
8.- Click in Burn, then wait to finish (i didn't have any issue at this point).
Then after that, insert the already flashed card into the tablet then turn on. A green progress bar (in my case) appears on the screen, then wait to be filled (complete), then the tablet should turn off. After that remove the card from the slot and turn it on again. The tablet should boot normally.
Hopefully it helps somebody, like it helped me.
