Windows Phone 7 Mango Firmware Leaks on Weekends

A downloadable stock RTM of Windows Phone 7 Mango has been leaked by Hobbyists on weekend. But there's a catch.

A downloadable stock version of the RTM (release to manufacturing) build of Windows Phone 7 Mango has been successfully posted by Hobbyists this weekend. XDA-Developers forum member said that the leaked 7720 build is the reference version and isn’t optimized specifically for any device. As such, some special features may be missing. The OS will work on a core level on most, if not all, Windows Phone 7 hardware. Microsoft’s chassis guidelines had led every phone to run the same Snapdragon processor families, or having much of the same part mix inside so far.

Upgrading through the leaked stock version is considered to be a risky move for almost all owners, since it don’t have the Microsoft’s approval and this might break the warranty. As such, owners who want to patch to a newer version of Mango likely won’t have an option except for getting a separate version of the generic updated build. Otherwise, they will need to revert back to the original firmware and do the usual upgrade method.
