[How To] Install The Leaked Android 2.2 FRF72 Build for Nexus One

Looks like a new build of the Android 2.2 Froyo FRF72 for the Nexus One was leaked yesterday after being handed out to Google employees earlier this week. We managed to download the file and put it up on our site for you guys in case the official google link gets taken down. Based on the file name, the build is an incremental upgrade from the FRF50, so you have to have the FRF50 build already installed to upgrade to this new build. No one has a clear idea what the update has in store for the phone but rumors are out that Flash support was updated and some improvements were made to make the web browser operate even faster. As we find out more info, we'll update you guys as well so stay tuned by following us on Twitter and/or subscribing to our RSS feeds.

Download the file by clicking here.

If you know what to do with it already, enjoy! If not, follow the instructions below:

1. Rename the file to update.zip. Note that if you’re using Windows, just rename it to “update” (no quotes, of course) because it’s already a zipped file.


2. Copy the update.zip file onto your microSD card.


3. With your Nexus One off, hold down the trackball and press the power button.


4. You’ll be booted into a white screen with three Android robots on skateboards. Select “Bootloader.”


5. On the next screen, select “Recovery.”


6. Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.


7. Now press the power button and volume up button at the same time. It could take a couple of tries.


8. Now (using the trackball this time) choose “Apply sdcard:update.zip” and let things run their course.


9. Scroll to the top and hit "Reboot"
