How to successfully install Windows 10 Mobile build 14951 (workaround)

Microsoft recently began the rollout of Windows 10 build 14951 to the Fast ring. The new release includes some subtle improvements and fixes, and a few features for both PC and Mobile.

Although users quickly began updating their PCs to the latest version without a glitch, users running Windows 10 Mobile on their phones have been reporting getting stuck at zero percent while trying to download build 14951 on their handsets. Thankfully, there's a few workarounds.

Microsoft quickly acknowledged the issue and now has already narrowed down the problem to an issue that is only affecting phones which have been previously updated to Windows 10 Mobile 14946. The company says that is currently making the necessary changes to properly publish build 14951, and the same changes will be part of future flights to prevent users hitting this issue again.

In the meantime, the company is now offering a few workarounds to help Insiders successfully install Windows 10 Mobile build 14951 on their devices.

In this guide, we'll walk you through the four available paths to download and install the latest test Windows 10 Redstone 2 update on your mobile device.

Wrapping things up

Although Microsoft has isolated the issue, keep in mind that these instructions are still being validated.

Finally, remember that some of this options will wipe out your phone, and as always, it's recommended to make a backup your data before proceeding.
