Just retried with the same recovery (re-downloaded), and the same thing happened. So then I tried with the one Maba links to, for upgrading to CWM5 (which i flashed like a month ago, and it worked) - but it does the same thing.
Did I just get myself a too expensive mirror?

I just realized that I can get it into CWM though. Maybe I should just try and flash the SNAPSHOT then, and see what happens. But have to go for an hour or two now - so will report back with whatever happens when I get home..
Hmm.. Maybe I should just leave it there, or just try to install the latest SNAPSHOT without messing with the recovery?
