Now that Android 4.0.4 for the Nexus S (i9023, i9020-T) is out, you may be wondering how to get your device up and running with the latest version of Android. Allow us to help. If you’re running stock 4.0.3 or any ROM with Clockwork Mod Recovery, the process to update your device couldn’t be easier.
For those of you with Clockwork Mod Recovery flashed, all you have to do is:
Power off your Nexus S, then once it’s off, hold volume up and power to boot into the bootloader
Navigate with the volume buttons to recovery, and use the power button to select it
You should see a warning triangle shortly after that, from there, hold down the power button and press volume up
Select apply update from /sdcard and choose the update file
Reboot your Nexus S with the menu option provided
Of course, using either method to update your Nexus S is your decision. Only you are responsible for what happens to your device. For any additional help, or more information on the update process, you can use the comments or visit the XDA threads for either the rooted ROM or update file.
I’ve been playing around with the rooted but totally stock ROM and so far, and I love it. Everything is very fast and super smooth. No problems yet.
And don’t forget, those of you who don’t want to get their hands messy, this update will be hitting your device before you know it. So just hold on tight.
