This will be my last post about the Google Nexus S since I just purchased (and received) my Nexus 4. That said, I really wanted to give one last update on the Nexus S since it looks like things have changed quite a bit with the update process. While it looks more complicated at first, it’s actually a lot more flexible now. Here is how to upgrade your Nexus S manually to a full 4.1.2 Jelly Bean, even if you have not received it yet/are in a country where the updates are not coming in, or are on a carrier which is not pushing OTA updates.
The first step is to go to Google’s Official Factory Images for Nexus Devices
Now, you have one of four choices for sections, based on your phone:
- If you have the (MOST POPULAR) T-Mobile or ATT (GSM) version of the Nexus S, go to: “Factory Images “soju” for Nexus S (worldwide version, i9020t and i9023)”
- If you have the Sprint (4G) version, go to: “Factory Images “sojus” for Nexus S 4G (d720)”
- If you have the Korean version (VERY RARE), go to: “Factory Images “sojuk” for Nexus S (Korea version, m200)”
- If you have the NON-1Ghz (STILL RARE) version, go to: “Factory Images “sojua” for Nexus S (850MHz version, i9020a)”
Let’s assume you have the T-Mobile/ATT one since most people have that.
You will want the “4.1.2 (JZO54K)” image, which you can download from their official link:
