  1. i’m quite certain your phone has to be unlocked or else entering recovery will be impossible. you can save the OTA to your ‘sdcard’ on the Nexus S – the internal memory is mounted as though it is an sdcard. my advice is to download this OTA and save to /sdcard/ update.zip then find the procedure to unlock your phone and then flash a custom recovery.. do not reboot, then enter recovery from the bootloader screen.. then flash the ota update.

    a warning though: you may not be able to enter your new custom recovery after flashing this OTA.
    to do that, you would need to firstly BEFORE rebooting, also flash the super user zip. then enter your new home screen and follow procedures to rename rename install-recovery.sh so that you can later enter the recovery if you wish to.

  2. Doc: No SD card on the Nexus S 3G – the 4G version has a removable/upgradable card. I wish this article could link me to instructions for my 3G.

  3. This some bull the duration time I tried after update I got 2 mbps the second I got 0.46mbps can I go back to 2.3.4 any way?

    • You could try installing a stock 2.3.4 firmware via the same method employed here. Just replace the file used here with a 2.3.4 firmware. You can find it on the Nexus S 4G forums on XDA.
      Hope this helps.

  4. There is NO SD card on the Nexus S4G!!!

    Your instructions are fine…up to pointing to an non-existent SD card.


  5. Absolutely not working for me, every time I try this, I get to the exclamation point part, press volume up many, many, many times and never get any other options. Any suggestions?
