In a hurried frenzy to try out the latest build for Windows 10 Mobile, some Insiders throw caution to the wind. Unfortunately, doing so may result in a less than pleasant Insider experience and in a few rare cases, Insiders might be forced to drop out of the Insider preview due to 'deal-breaker' issues.
According to the known issues list for build 10512, rolling back may be something many of us end up doing over the next couple of days.
Some phones with a large number of tiles pinned to the Start screen may get stuck in a state where the device shows “Loading…”; the device will need to be reset or rolled back to Windows Phone 8.1 using Windows Phone Recovery Tool.
As Windows 10 Mobile Insider build 10512 begins rolling onto devices, there will undoubtedly be Insiders who have to reboot, restart, rollback and re-enroll in the Insider preview in the coming days. Fortunately, we’re here to help.
A quick overview of the Insider Program may help new as well as current Insiders gain a better perspective on what Microsoft is releasing and what Insiders should reasonably expect. The Insider program is an extension of Microsoft Beta preview program that has been a part of Windows since forever. However, the Insider program (formerly Preview Program) is far more communicative and quicker than previous Beta Preview efforts by Microsoft. Insiders are given access to more builds, and the Windows team is given far greater feedback on a more continual basis. It’s typically a win-win for both Windows users and Windows developers.
Due to the nature of the Insider Program and the speed at which development is occurring, Insiders are given fair warning that builds they receive are often less than optimal. Microsoft does provide ways to avoid builds, reschedule them and in rare cases, a rollback from them.
For Windows 10 Mobile builds, there is a recovery tool that will help Insiders rollback from a glitchy, buggy or broken build they receive during the Insider process. Barring the device is not bricked, follow the steps below and you should be able to restore your device to Windows 8.1. Once restored, Insiders could give the latest Windows 10 Mobile build release another shot, and another, and another until it works for them.
First, you'll need to make sure you have a few pre-requisites satisfied. You'll need a Windows 7 or newer computer, with at least 4GB of storage space, and a USB cable to connect your phone to the computer. You'll also need a Lumia phone, this recovery tool was developed by Nokia. Connect the phone to a PC, open the recovery tool and follow the guide. It could take some time to restore the device fully but once it is done, your phone should be back to factory working order.
Good luck Insiders.
