If you have a Lumia 930, preferably a carrier unlocked one or are in the UK, you may want to check for an update. Earlier today reports started to surface in our forums about a new, critical update rolling out to various 930s.

The update is not, however, Windows Phone 8.1 Update 2. Instead, this looks to be a small firmware patch to fix a serious issue where the phone could spontaneously reboot. A user in our forum, danmorrissey, described the problem and when he noticed it:

"I've had that issue recently, but it's always when taking or looking through pics, so assumed it was camera beta causing the issue.."

The update itself reads:

"An important update is ready to be downloaded. Windows Phone 8.1 – This update fixes a critical issue that may cause your device to periodically reboot. Please install it now so that your phone will keep working as intended."

After the update, the following version numbers are reported:

  • OS version: 8.10.14226.359
  • Firmware revision number: 02540.00019.14522.26006

No other changes are included, especially since this is not Update 2. Indeed, so far Update 2 is not, to our knowledge, planned for the Lumia 930. However, some users were able to exploit an early hole in the Windows Insider program to get the OS upgrade indirectly. It is also not clear if all or just some Lumia 930s are eligible for this update.

Microsoft has also published a short post about it in their support forums:

"We identified a problem in some versions of Windows Phone 8.1 that could cause a phone to restart periodically. A critical update will fix this problem. If you're unable to install the update or want to learn more, we can help you fix your phone."
