Microsoft newly launched Lumia 950 and Lumia 950 XL  runs on Windows 10 Mobile build 10586. The build is the RTM candidate for public release on existing Lumia devices running Windows Phone 8.1.

The company recently released the cumulative update, build 10586.29 for Lumia 950 and Lumia 950 XL bringing some security fixes and improvements. However some users are facing issue when upgrading their devices to build 10586.29 and Microsoft had to pull the update from their public servers. According to Microsoft the users are facing the following issues:

  • Update not being offered on your devices
  • Upgrading to new build, get stuck at 0%, and
  • Very low storage warnings

Microsoft said the following statement:

First, we want to thank everyone for their open and candid feedback on the update experience so far. Please know we’re reading your comments and hearing you loud and clear. Your input is incredibly valuable in helping us address your questions with timely updates and fixes.

We are aware of issues related to the recently published Windows 10 Mobile update, including: update not being offered, update appearing to get stuck at 0%, and pesky low storage notifications. The team is working on fixes and improvements to the upgrade experience in the short-term and with future releases. In the meantime, we have unpublished the 10586.29 update for Windows 10 Mobile from our public update servers while we work through these reports.

For those of you who still see the low storage notification: while bothersome you can safely ignore this message.

For those of you who still have pending updates (OS or apps): make sure to plug your phone into a charger and leave untouched while it works through those items.
