Some Windows Insider members cannot update to the Windows 10 Mobile 14926 build due to an install error. Microsoft is investigating the issue, but it also has a workaround that may solve the problem for some users.
The specific error message number is 800703ed, which indicates an update to the new build gets started but then fails. In a Twitter post, "Jason", the Program Manager on the Windows Insider Engineering team, says that people who encounter that error should try removing the SD card from their phone and try the build install again. Jason added in a follow-up post:
This isn't a guaranteed workaround, but it's something we're investigating. Any feedback would be extremely helpful. Thanks!
Have you encountered this error when you tried to update to build 14926 for Windows 10 Mobile, and did Jason's workaround work for you? Let us know in the comments!
