Hi,
recently I reflashed my 770 because some applications stop running.
So, newly flashed, without restoring backup, I tried to install something, but when I tried to update the list, it doesn't download anything and I can't put any new repository because the first, http://catalogue.tabletee.nokia.com/certified/ mistral user, is the one that doesn't refresh, and is not "enable"/"disable", so its impossible to use application manager.

There is any kind of fix?
Thanks

Solved flashing the device.
