Hi,
This is just a quick note for the people who are on the Windows Phone 8.1 Update and are trying to install the Lumia Cyan firmware update.
Even if the Cyan update is available for you phone. It will not install when you are running the developer preview. To get this installed, you need to be ok with wiping your phone (Backups may be a good idea). The steps to get your phone updated are:
- Download the Nokia Recovery Tool
- Run the tool which will wipe your phone and reset it to an earlier released OS (Mine was to WP 8.0)
- Once the phone has updated, You then need to go into settings and select Phone Update.
- Once this update is finished Go back to 3 until the updates are completed before carrying on.
- Re-download/run the Developer preview app enable the preview on the phone
- Check for update again until there are no more updates and to get your phone back up to 8.1 Update.
This process takes a loooooooooong time so be prepared to spend a couple of hours doing this.
