Mobile Build 14951: Update Screen Shows "0% Downloading"

Hello Windows Insiders!

We've just launched build 14951 to the Fast ring today and we're seeing reports from users staying their device is not progressing past "0% downloading" on the update screen.

We encourage Windows Insiders to file feedback or upvote feedback from others.  We've started digging through the logs we have already received to investigate the issue.

Stay tuned to this thread for additional details.  We'll post updates as information becomes available.

Thanks in advance!

*** Edit 2016.10.19 -  9:45PM ***

In reviewing device logs from feedback submissions, some devices are needing to be plugged in.  As an interim step, please plug your device into a charger and allow it to fully charge if it is not.

To everyone who is waiting patiently, thank you.  We know this is not the usual experience!

We are still actively investigating and trying to root cause the issue.  No new information to share currently regarding solution, workaround, etc.

More updates to come.

THANK YOU to all the Windows Insiders who have provided us feedback on getting stuck at 0% while trying to download Build 14951 on their devices. We have narrowed this down to a new issue that only seems to affect devices on Windows 10 Mobile build 14946. We are making a change to how Build 14951 is published, so that Insiders can avoid hitting this issue. We will also make the same changes when we published the next build so Insiders do not hit this when upgrading to newer builds.

We appreciate all of the feedback that has helped us out.  We are still working on validating this resolves everyone’s issues; please keep filing feedback if you run into issues trying this out.

Here are 4 options we are validating to get out of this state: 

  • FASTEST  - You can force the update session to time out by:
    • Plug your device into a charger
    • Open Settings > Update & Security > Windows Insider Program -  Change your device to "Slow" and then back to "Fast"
    • Turn on airplane mode Settings > Network & wireless > Airplane Mode
    • Navigate to Settings > Time & Language > Date & Time -  If On, turn “Set date and time automatically” to the Off position
      1. Change the date on the device to 7 days in the future
    • Return to the home screen & Reboot the device
    • After the reboot, turn off airplane mode - Settings > Network & wireless > Airplane Mode
    • Check for updates - Settings > Update & Security > Phone update > Check for updates
    • This process will fail with an error code.  This is expected!
    • Change the device date back to the current date - Settings > Time & Language > Date & Time
    • Check for updates -  Settings > Update & Security > Phone update > Check for updates
    • This check may fail again, this is ok.
    • Reboot the device
    • After the reboot, check for updates - Settings > Update & Security > Phone update > Check for updates
    • The check for updates should succeed and begin downloading 14951

      *Note*  We have seen several instances of users reporting getting error code 80242006 after this last check for updates.  We will be doing some additional testing on our side for this, but in the mean time, Insiders are awesome and have noted these additional steps seem to bypass this final error message:

    • Switch Insider setting to Slow ring
    • Check for updates (will say you are up-to-date for the Slow ring)
    • Change back to Fast ring
    • Check for updates again and it should update

    And if you're *still* stuck?  Here's one additional set of steps to try:

  • EASIEST-LONGEST - If your device is already in this state, it will timeout after 5 days. Once the update times out, your device will get the updated metadata and should move forward as normal with download Build 14951.
  • MEDIUM WORK - If your factory reset your device on Build 14946 - Settings->System->About->Reset your phone – you will be able to download 14951 without issue now.
  • MOST WORK - Less optimal, but if you have already rolled back to an older build such as Windows 10 Version 1511 or Windows 10 Anniversary Update using WDRT, you can easily move forward avoiding this issue.

I have a Nokia Lumia Icon (929) and it's not updating.

0% on 950XL here too.

[Update] ...

Ran the suggested 'Fastest' option in the '2016.10.20 - 6:10PM' Update in the original post.

Currently download is at 30% continuing.


Happening on 950, 950XL, 930, and 929 (Icon). All soft resetted. 950 has just been restored with WRDT and updated to 14946 earlier today and setup as a fresh device and still has this issue. Seems to be on your guys end.
SP4 i7 | Custom PC Z97 i7-4790k || Lumia 950 | Lumia 950XL | Alcatel Idol 4S | iPhone 6

Tested RS1 14393.321 updated to 14951 without any issue.

But RS2 14946 update to 14951 caused 0% downloading.

This is extremely helpful.  Thank you for running this comparison.
Unlocked Lumia 950 - 0% updating from 14946
Surface Pro 4 • i5 • 4GB RAM • 128GB SSD
Seeing same issue on my L735. Won't download whether on WiFi or cellular data. Can't leave feedback since I can't login to Feedback Hub on 14946.
My Lumia 535 has the same problem. Stuck at 0%. If I restart get a notification about messaging app updates. Not sure it is related but the notification has shown up all 3 times I restarted. At time on the phone update screen the 'Updates are available' and the 'Downloading updates x%' texts along with the progress bar disappears. 

Do not tell me that we we must return to the 14393? 

With my 640 would have to return to 8.1, lot of work... We need the 14939 in Windows Device Recovery Tool!

Tested 14936 updated to 14951 also without issue.
