Walshed tool lets bootleg WP7 NoDo updaters go on
Developer Chris Walsh has put out a tool to help keep Windows Phone 7 updates going for those with unofficial versions of the Walshed tool mends NoDo installs loaded using the ChevronWP7 hack so that they can keep receiving official updates from Microsoft. Unlike most unofficial firmware tricks, the new tool is officially sanctioned by Microsoft as a way of getting the phones back on the official path.
It primarily solves the issue behind the "80180048" error codes in the Zune app, and an equivalent in the Windows Phone 7 Connector for Mac app, that prevented the upgrade from even starting.
ChevronWP7 had been used by many to speed up the NoDo update in areas where the patch didn't hit quickly. Americans on AT&T were the most frequent candidates since AT&T was far later than other carriers in getting the upgrade. Microsoft warned that the particular approach used to load the firmware 'broke' its official state and, while the unofficial firmware would work, it couldn't pass as an official firmware eligible for an upgrade.
