If you are using a Windows Phone, you would be probably knowing that you cannot install custom themes on the phone and you can only select the available set of themes from the settings. But if you have an unlocked phone, you can install more themes (accent colors) on your Windows Phone using the free app Theme Install. For using the app on your phone, you need to have a full unlocked phone. The app is created by XDA Developers forum member.

Instructions to install the app:
- Deploy .xap
- Launch app
- Click Install button (installation takes a second)
- Close app
- Now Go to “Settings – Themes” and check the new themes.


The app was tested on Lumia 710, but should work on other Windows Phones as well.
