How to Install Android 2.2 Froyo on Motorola Defy
Android is probably the best mobile OS out there. iPhone users may disagree, but there are many who would agree with this statement as well.
There are now scores of Android devices available in every possible budget range and category, in every size and shape. The Motorola Defy is a very capable Android smartphone too. It comes with an 800 MHz processor, 512 MB RAM and a 3.7 inch capacitive touchscreen display. It also has a 5 MP camera. It is priced quite well and offers a good overall package.
One of its major shortcomings though, is that it still runs Android 2.1 Eclair when almost every high end Android smartphone has upgraded to Android 2.2 Froyo. Google has also launched Android 2.3 Gingerbread with the Nexus S, and many phones are expected to get the Gingerbread upgrade in the coming months.
We also have published a lot of guides for many phones which explain how to install Android 2.3 Gingerbread on your Android device, but unfortunately, no ROM is available yet for the Motorola Defy.
We do have an Android 2.2 Froyo ROM for the Motorola Defy though, so you can install it easily. In this tutorial, I will explain how you can install Android 2.2 Froyo on your Motorola Defy.
