For those like me, who have a bricked phone and would like to solve the problem, since the download links of the officials ROM's here at Xda aren't working any more, i ask to search your pc's and post here those ROMS.
Thank you very much.
P.S.: I have the following roms:
1.30.514.2 (Portuguese, WM6)
1.27.405.1 (Worldwide English, WM6)
I also have this one, but I don't know what it is, probably a earlier rom.
