Can you be more specific? Yes i can access setting, but i don't know exactly where to go to delete it. I already unticked "Download Update File for System Software" under "System/Auto-start Settings"If you're able to reach the Settings program you can search for Download Updates (or called something similar) under the startup programs.
If you untick the box there it deletes the update from your memorycard (there is no notification that it was deleted, but it should work)
