How to Install Windows Phone 8.1?

As we said before this is a developers preview which means you need to have a developer account. Unless you are a real developer, you might not be interested in signing up the Microsoft Developer site by paying a $19 fees. But for a normal user, you can still get a free developer account. Here is how to do it.

  1. Sign up for Microsoft’s App Studio: appstudio.windowsphone.com which is free of cost, using your Microsoft ID which is used on your phone and allow them to register your email address. Once you have the confirmation on the account created, now you need to install an app on your phone.
  2. Install the Preview for Developers app and then sign in with the same ID which you used to create the App studio account in step 1.
  3. Now you can see an option “Enable Preview for Developers”, check the option and click done.
  4. That’s it. You are now enrolled to the developers program. Now when the update is released, Go to Settings-> Phone Updates and click check for updates button and you will be able to see the updates.

  1. When will this coming? Still not coming to my phone.

  2. Does WP 8.1 preview runs on 525 without any issues. Ashish help me

    • This will run on all Windows Phone 8 devices, but be warned that this is a preview build and you might see issues. So if you are ok with it, you can install.

      • after installing the preview for developers i’ve installed the first two updates then when im downloading the third update it is getting downloaded till 50 odd percent and telling update cannot be downloaded, the same has being repeated even if i try again,can you please tell me whats the problem?

  3. is this avilable in india for lumia 520

  4. I’ve installed WP 8.1 OS on my 720… Now mobile performance is really worst..
    It takes much time to get photos loaded.. There r many drawbacks.. Many apps r not opening at all..
    Battery life has been dropped drastically.

    Now how can I improve my lumia performance ?? :(

    • If apps are the issue, then the migration is not proper. What you can do is to install any new keyboard or language pack from the settings. This will force an update which will rectify the app issue. Well, regarding battery performance, check the new Battery app and moreover this is a preview and we cant complain much as this is not a forced update.

    • go from win 8 agin.otherwise wait 1 or 2 month.

  5. “RE: It will not damage your phone or cause any issues.”

    Refer to Section 7.c. at http://dev.windowsphone.com/en-us/develop/devpreview:
    “YOU AGREE TO WAIVE ANY SUPPORT FOR YOUR WINDOWS PHONE FROM THE MANUFACTURER OF YOUR WINDOWS PHONE AND MOBILE OPERATOR OF THE NETWORK THAT YOUR WINDOWS PHONE WORKS ON. YOU AGREE TO WAIVE ANY RIGHT TO RETURN YOUR WINDOWS PHONE TO YOUR APPLICABLE OEM, ODM OR MOBILE OPERATOR.”

    I am not entirely convinced that waiving off support for the phone is a healthy choice for the regular mortal user.

    • Well, cant blame them. Some operator which have phones in contract have this issue of warranty and support. But this will go off once you install the final version.

  6. Hey Nirmal, I have updated my lumia 520 twice to windows phone 8.1 using the same steps. Still the phone is not updated. need help.
