I Managed to recover the unit.
What I made was whe the unit was starting the boot I pressed and hold the power off button until appear a screen asking if I want to power off, ansewred yes and the unit powered of ant then when I tryed to turn it on again it worked.
The problem is that The Voice Brazilian Potugueses TTS file, The Portuguese text files , the Keyborad Language files and keyboard lay-out files was missing.
I managed to recover the voice and text files (had it in my back up, but the Keyboard language and lay-out I don't back-up .
Does anyone can send me such files?
