There have been reports that some Windows Phone users were experiencing BitLocker issues after upgrading their handset to the latest Cyan update, but a clear confirmation of who was experiencing it and how could not be made. It now seems that the users being affected are Windows Phone 8.1 Preview for Developer users who are using BitLocker full disk encryption through their companies, having their devices bricked after updating to the latest Cyan update.
Microsoft is said to have issues an official statement and recommends users to downgrade from the preview version of WP 8.1 to the commercial software before attempting to upgrade to the latest Lumia Cyan update. Along with the latter, the company has also suspended the preview program, which includes the 12400 build as well.
“We are currently investigating the issue. We have paused delivery of the update to customers using the Preview for Developers, and will resume once a fix is in place. Customers whose phones have been affected should use the Nokia Software Recovery Tool to return your Lumia to a normal commercial software state before downloading the Lumia Cyan update.”
Users who are still running on the Windows Phone 8.1 Preview for Developer software and noticed that the Cyan update is not available for them should know that Microsoft has postponed the Cyan rollout for the given preview software until a fix is available. For those affected by the BitLocker issue, Microsoft recommends using the Nokia Recovery Software Tool in order to return the handset to a commercial software in order to regain functionality of the device.
