tried to flash recovery with PIT realized only after that repartition was selected, but nothing changed.
tried to flash firmware with PIT, unselected repartition, and i supposed i bricked it. Still, on charge shows the battery, but no other response. damn.
[EDIT] The tablet is still alive, I found on another section that letting it charge and pressing volume button, can make it wake up and..."yes"! We are back at soft brick as before...same exact situation!
