Remember the Windows Phone 7 updater by Team ChevronWP7 that allowed you to update your WP7 phone regardless of what model it may be and the warning Microsoft issued about it possibly putting your phones into an unserviceable state?
There were disputes over the whole issue, with some folks saying that they’ve received notifications to official updates even after updating their phone unofficially. Well it looks like it does’nt matter anymore. Regardless of whether it negatively affects your WP7 device or not, the ChevronWP7 updater has been pulled off the internet because Microsoft told the developer that the tool was “breaking phones.” So there might be a possibility that users who updated their phones with the unofficial updater could be stuck on NoDo forever. The developer is working on how to rectify the solution, but until then it looks like a system restore of the phone to its original state should do the trick, which not many users are willing to do for now. I guess we’ll have to wait for the next WP7 Update to arrive first. Read the blog post about the updater being removed.
