HealthCliff74 has laid down three methods for updating the tile situation. They are-
  1. The ShellTile.Update(ShellTileData)- This is a method that will permit the user to manually update the contents of the live tile from the application or the background task of the application. These Apps use them for the creation of custom tiles. For instance a Twitter user may register a background task that checks twitter feeds and writes these text updates on the live tile. He stated that he did not face issues when using this functionality in both the WP 7.5 and the WP 7.8.
  2. The ShellTileSchedule.Start()- This is a process that permits the setting of a URL for a live tile image on an external host. This URL is been fetched at interfalls that have been pre-defined. HealthCliff74 found that the Shell Tile Scheduler has begun behaving erratically under specific circumstances. This application from his previous blog post had used the above method and he has made an attempt to isolate the circumstance that sets off this issue. If this problem takes place it is a serious one. It seemed specific to WP 7.8.
  3. HttpNotificationChannel.BindTo ShellTile()- This is a method that tends to open a channel to the Microsoft Notification Servers. Here external sources are able to post texts, counters and images to the Microsoft Notification Servers. This is routed to the phone and he has found this functionality to be interrupted on the WP 7.8. The user can send a counter or a text. The moment the URL for one live tile image is been sent to the device, the phone closes the endpoint to the server and nothing is updated at all. http://www.nokiaphones.net/
