If you are one of those, you will probably have to update your smartphone to the current version of Windows Phone via a public mechanism and then try installing Lumia Cyan on the device.
We don’t believe that there will be another fix for this particular issue affecting a small number of Windows Phone users, but anything is possible. We will keep an eye out for additional details on the matter, so stay tuned.
