Google Nexus Unbox - 42And the manual update is finally here! Google released Android 2.3.3 software update for the Nexus One and the Nexus S yesterday, but that will be rolled out to everyone in the coming few weeks.

Like always, the manual download links are out and available for the impatient. If you can’t wait for the official download notification to show up, follow the instructions below.

How to Install Nexus One (GRI40) Software Update

Here’s a detailed tutorial on how to install the Android 2.3.3 (GRI40) update on your rooted Nexus One. I have previously done a similar tutorial on how to install Android 2.1 (Update 1) manually, and I will be following the same steps in this case too.

Disclaimer: Try this on your own risk. I’m not responsible if you mess up with your Nexus One.

1. Download Gingerbread GRI40 the Nexus One Android 2.3.3 software update (GRI40) on your PC.

2. Rename the downloaded .zip file to ‘‘.

3. Connect and mount your Nexus One SD card on your computer using the USB cable.

4. Now copy/paste the file to your SD card. Make sure the file is in the SD card root. It should not be in a directory.

5. Then turn off your phone.

6. Now to get in the bootloader mode, turn on the phone while pressing and holding the trackball and power button.


7. Follow the navigation instructions on the screen. Select BOOTLOADER and then go to RECOVERY.

8. Assuming you have Amon RA’s recovery, scroll down to “Flash zip from SD card” and press the track ball to open it.

9. Using the trackball, select your “” file. Confirm the installation and the installation procedure should start now.

10. After the installation completes, reboot the phone by selecting “reboot system now” from the recovery menu. It might look as if stuck again on the Android bot, but it will soon reboot.

That’s it! You’re Nexus One should have the latest software update installed on your phone! Go to Settings >About phone to verify.
