Manually Install The Official Android 4.1.1 Jelly Bean OTA Update On Nexus S
By on July 20th, 2012

Google has just started rolling out the official Android 4.1.1 Jelly Bean update for the Nexus S via OTA in certain regions of the world. The OTA update will however take some considerable amount of time to be available in different regions of the world, and to the different variants of the handset.

If you cannot wait for the OTA update to be available in your region, and want to update your Nexus S to Jelly Bean manually, follow the instructions below.

The steps below are only valid for the I9023, I9020T and the I9020A variant of the Nexus S. Also, make sure you have root access with a custom recovery like CWM installed. 

Step 1: Download the stock Nexus S Jelly Bean OTA update from here. If you want root access, download the Superuser zip file from here.

Step 2: Once the download is completed, transfer the zip file(s) to your Nexus S. Reboot your phone into CWM Recovery mode by using ‘Quick Reboot’. Navigate to the ‘wipe data/factory reset’ option first using the volume keys, and select it by pressing the Power button. Then navigate to ‘Mounts & Storage’ and from there select the ‘format /system’ option.

Step 3: Finally, select the ‘install zip from SD card’ option and then select the Jelly Bean OTA zip file that you downloaded in Step 1. If you also want root access, flash the superuser zip file as well.

    Wait… Why do I have to have ROOT? I always do it like:
    1. download update.zip2. turn off phone, do volume up + the button (which you turn off phone :D )
    3. update from sdcard/
    4. done, start phone
    Why is root needed now? It is OTA, isn’t it?
    Please explain me it. Sorry for my English, I am Czech :D

      Actually, I have the same question :)

      You can only flash manually if you have a custom recovery installed which requires an unlocked bootloader. Google no longer allows manually updating on their stock recovery due to security reasons.

    Hi! It’s only work with a rooted Nexus S, or is it possible to update it without clockwork mode?
    When I updated from gingerbread to ICS, I just had to start the bootloader and select install update from sd card. In this case it doesen’t work?

    Thanks for the credit but could ya link to my xda thread with mirrors instead of direct file linking (host isn’t happy lol)?

    Again thanks :)

  • Jeremy

    Will this only work from ICS or can I go straight from Gingerbread?
