I downloaded the file from the previous link to dropbox, uncompressed it (apparently without problem) in my iMac and flashed it with ATK.
The process finished without any trouble; but now my kindle is in an even worse state than before. I mean the reader re-started until the progress bar reach a 20% or 25% of the total; now it stops before the bar even appears.
After that I checked the .zip file (the one I have downloaded before) in XP with Winzip and it said it is corrupted.
So I think the file was always bad, although my iMac did not give me any warning.
I will wait for new links.
