If during the installation of Windows 10 Mobile build 14342 your phone gets stuck at the Windows logo screen, then use these workarounds to fix the issue.
After Microsoft accidentally rolled out a pre-release version of Windows 10 for PC, the company is now once again aligning the version of the operating system for PC and Mobile with the release of Windows 10 Mobile build 14342 to the Fast ring.
The new update brings swipe navigation gestures for Microsoft Edge, Apps for Websites to allow certain sites to open with an app and a lot of new fixes. However, a small number of users has also been reporting that an issue where the phone may get stuck at the Windows logo screen during reboot after the installation of build 14342.
Microsoft is aware of the problem, and it's proactively investigating to find a solution for this issue. In the meantime, the company is offering two temporary solutions to get around the problem.
How to fix the install of build 14342 on MobileAccording to Microsoft, you can fix the Windows logo stuck at reboot in two different ways.
This first workaround involves being patient. The company said that if you come across the issue, then wait between 30 and 40 minutes when you see the Windows logo stuck on the screen to allow the handset to complete the data migration and installation of the operating system.
If waiting didn't fix the problem, the second workaround is to force-reboot your phone. You'll do this by holding the Power + Volume Down keys for at least 11 seconds.
Once your force the reboot, your phone will vibrate, boot again, and it should continue with the installation.
In case, your phone again stops at the Windows logo screen, don't do anything else, as it'll eventually complete the installation. However, make sure your phone is connected and charging during the process.
It's important to note that if you don't wait and try a hard reset, your Windows phone will fail, in which case you'll need to use the Windows Devices Recovery Tool to recover your handset.
Users running into this issue have been reporting that the Windows Recovery Tool successfully detected the bricked phone and the software was able to reinstall the original version of the mobile operating system.
