How to manually update a rooted Nexus One to Android 2.2 ( Froyo )

The latest Android OS version is out and if you own a Nexus One you must get it on your phone. There are 2 ways to do that: the first is the official method, were you have to wait and have the luck to receive the random OTA update. The second method refers to the steps bellow, a guide that will install and update the Nexus One to Android 2.2. This tutorial is also available for the non-rooted Nexus One.

Before you begin, you should know that the procedure bellow only updates a rooted Nexus One to Android 2.2. The Froyo version is the official one, exactly as the OTA with a full user access added. We strongly suggest doing a Nandroid backup first ( go into recovery mode and click backup ) because you will have to wipe all of your data.

Guide to update a rooted Nexus One to Android 2.2 ( Froyo )
  1. Download the rooted Android 2.2 and save it into your PC. Using an USB cable, transfer this file into the root folder of your microSD card. That means the main directory. Note: The file above contains the version with Radio included. If you do not want radio, download this instead.

  2. Turn off the phone.

  3. Hold down “power” and “volume down” until the skateboarding androids come up then press “volume down” to highlight recovery. Press “power” button to select it.

  4. You are now in the custom recovery mode. Select “Wipe Data/ Factory Reset”.

  5. Select “Flash.zip” using the trackball and wait for it to flash. Then reboot. For some users this would take a bit longer, so do not worry. Nothing wrong happened.

  6. Success. You have managed to update a rooted Nexus One to Froyo.
