How To Update Nexus One To Android 2.2 Manually

By Ali Waqas on May 23 2010 8 Comments

After Google rolled out Nexus One upgrade, many lucky N1 owners got their firmware upgraded to the all new, cool and speedy Froyo. So, what about those N1 owners who either didn’t get the lucky upgrade push notification or those who happen to own a N1 outside the USA?

Here is how you can manually upgrade your N1 software to Android 2.2.

1. To start of with, firstly download this Android 2.2 firmware here. After you have downloaded the file, make sure to rename the file as Update.zip. If you are running windows XP then it is important to double check the name of your file which should be update.zip and not update.zip.zip.

2. After you have this file renamed, copy it to your device’s microSD card using any method you prefer and power off your phone.

3. Now hold the volume reduction button as you power up your N1 again. At this point a popup screen should appear that indicates the phones searching for various files etc.

4. Now tap down to recovery and push the power button.

5. After this a popup triangle with an exclamation should appear on the screen. At this point press the power and the volume up button together and select “Apply sdcard:update.zip”.

Wait for a while and screen will display install from sdcard completion message. Now simply reboot your device and there you go with Android 2.2 on your N1. Enjoy faster, durable and incredible Froyo and let us know what you think.

It is important to note that this method is for non-root users only. We will also cover a way for rooted users to update to Android 2.2.

        Hi Ali,

        I tried the steps above.
        When I get to the “apply sdcard:update.zip” step, clicking on it gives me the following error.

        E:signature verification failed
        Installation aborted.

        What’s causing that?

        Thanks,
        Tee

          make sure the file name is update.zip not update.zip.zip where windows manually adds the extions for you. also make sure it is on the root of the SD Card

            Hi Jeffrey,

            Yes the file name is update.zip (I’m on mac) and yes it is on the root of the SD Card.

            I tried wiping data and still same issue. Any other suggestion?

            Thanks,

              Having the same problem here. Looks like the file’s no good. Guess I should have jumped on the bandwagon earlier.
