How to install the Windows 10 preview for phones
The first Windows 10 preview build for phones finally rolled out yesterday—that is, if you happen to own a midrange Lumia phone that’s capable of running it.
Much to the chagrin of some enthusiasts, the preview only works on a bare handful of recent Lumia phones: the 630, 635, 636, 638, 730, and 830. Small as it is, this list does bode well for future compatibility with existing Windows 8.x phones, since it includes phones with low-end SoCs and 512MB of RAM. OEM and carrier shenanigans could still keep every phone from getting an official update, but unlike the move from Windows Phone 7 to 8, hardware doesn’t appear to be a limiting factor.
For now, if you want to test the preview but you don’t have a compatible phone (or if you want to test it without messing up your primary handset), the best bet for US buyers is this Lumia 635 GoPhone that Amazon is selling for $50. This cheap prepaid phone is locked to AT&T, but it will work just fine on Wi-Fi even without service. The hardware itself has a couple of caveats (low RAM, no webcam) but is otherwise pretty great for the price.
If you have a compatible phone but you’ve never dabbled in Windows Phone previews before, these instructions will take you through what you need to know. If you upgrade and suddenly find yourself waist-deep in beta software bugginess, we’ll also walk you through the process of downgrading to stable software.
The Windows Insider app is similar to but separate from the app that delivers Windows 8.1 developer preview builds.
If you’re already signed in with the Microsoft account you’ve enrolled in the Windows Insider program, you just need to tap “get preview builds.” Otherwise you’ll have to sign in first.
SO , in the next section you must choose between insider fast or slow , we recomend you to choose slow , because it will got less problem in feature
Now you’re ready to check for updates. If you want to pick a different update track later, come back to the Windows Insider app post-update.
Go to Phone Update in the Settings and start downloading. This may take several restarts.
Note : If you have an unsupported phone, this is what you’ll see if you try to install the preview. This is on a Lumia 520. Microsoft is supposedly finishing up a partitioning tool that will enable installs on other phones.
