It appears NoDo is rolling out without too many hitches -- other than the obvious issues with carriers -- so we haven't heard too many noises from users online who've had bricked phones because of the update. Nonetheless, Microsoft has released a tool to further help make sure that the update goes as smooth as possible, and the tool even promises it can "unbrick" some phones.
Wpcentral reports that you can get the tool as of today, and that it supports two "specific" error codes that some users have been getting;
800705B4: The timer ran out on what we were trying to do.
80180080: We couldn't update your phone because your operating system might be corrupt.
The latter specifically fixes an issue where the phone displays a black "Connect to PC" logo because the update failed part of the way through. The tool stops end users from having to figure out what the issues are -- be it with hard drive space, or resetting their phones. Jump on over to Microsoft support for the download now.
NoDo, which is rolling out worldwide on selected carriers, brings Copy & Paste support to the platform, along with other improvements, including performance and marketplace fixes.
