hey guys, i dont know how to fix this.. its saying my application data is full
iv opened it and checked with application.. its saying over 2GB is used from "Other Installations"

not really sure what that meant.. but iv tried uninstalling heaps of apps and nothings changed

why is this a problem? well.. its saying my memory is full, and im now unable to view my received sms as well as delete any emails. all my folders are open (as in.. folders holds apps.. but now the apps are everywhere and i cant put them back in their folders)

its weird, coz i can still receive sms.. but when i click to view them, it wont display so i cant actually read the sms
i can send sms but it will sit on "sending" and wont do anything


so i dont know how to remove or fix my application data being full.. how do i empty it?

Are you running pr1.3. Did you restore a backup from pr1.2 when you upgraded?
your emails have been doubly restored. Do a full reflash including the emmc. Don't restore any back up. For your smses beforehand sync with Nokia suite after which restore back from there.

How I can reflash the n9?

Type that phrase into Google, or any other search engine. You might be amazed with the results.
