i asked at the GSM section but they aren't giving me some help, please as i see that u know better here, don't u know something to do in this case, something like the last thing to do, couse i tried with the micro SD but it does nothing, when i restarted it (volume down, center button and reset) it asks me if i want to make things like were at the manufacture, after that it loads and restart, returning at the first screen as it was before.
