It looks like there could be a problem with the recently released ChevronWP7.Updater that was posted a few days ago by Chris Walsh.



From WPCentral:

According to Microsoft, the use of ChevronWP7.Updater could possibly put the updated Windows Phone 7 device into a state where it cannot receive future regular updates to the OS anymore and the only fix will be re-flashing the device with an original stock ROM. At the end of the day if could mean that such Windows Phone 7 devices have to be send to the manufacturers or carriers service centers because unlike for Windows Mobile, stock ROMs are officially not available as a public download for end-users.

  ChevronWP7.Updater pulled, breaks future updates on Windows Phones? Maybe not.
