Install And Update Latest Android ICS 4.0.4 Firmware On Your Sprint Nexus S 4G

Sprint Nexus S 4G Phone

The Sprint Nexus S 4G device was launched sometime in 2011 and it featured the Android 2.3 Gingerbread. But, since then, it was updated to Android’s 4.0 ICS and now another version of ICS, the Android 4.0.4 beta version, has been leaked. If you continue reading the instructions listed in this post you will be able to successfully download, install and update your Sprint Nexus S 4G smartphone with little effort.

For this guide to work, you will need a rooted device and as you might know, by rooting it you will lose the warranty which can be restored only if you return it to its default stock Android firmware. Also, before we can move to the first step of the ICS 4.0.4 firmware update process you will need to learn how to correctly prepare your phone and what files and software you need to backup.

Remember that this isn’t an official update for the Sprin Nexus S 4G device, but a leaked beta version for 4.0.4 ICS and it might pack some bugs and errors. Also, the device you’re installing it on needs to be rooted. Now that you know all this, it means that you are ready to learn what are the pre-requisites before moving to the tutorial guide. Here’s what you need to take into consideration and what software to install before applying the Android 4.0.4 ICS firmware on your Sprint Nexus S 4G:

  • make sure to create backups of all your data files such as video, music, movies, pictures, documents etc, as these might get lost during the updating process.
  • the firmware update will erase all SMS texts, Contacts and Call logs from your phone and if you need them, then you should create backups of these files also.
  • save the APN and MMS Settings which will help you connect to the internet after the update will be completed. The info can be found by opening Settings, Applications, then Wireless and Network and select Mobile Network where you should find the Access Point Names menu.
  • make sure that you’re device’s battery charge level is over 80% and that will prevent your device from discharging during the firmware update.
  • the USB debugging options has to be enabled; do it by opening Settings, then Applications, select Development and tick the option that say USB debugging. While you’re performing this action, the phone has to be disconnected from your PC.
  • as I’ve told you the phone has to be rooted before moving to the tutorial guide, also the Clock Work Mod recovery mode needs to be installed on your device, which can be downloaded from this Google Play Store link.
  • the info listed here works exclusively with the Nexus S 4G on Sprint model.

If you’re read and applied all the instructions above, then it means that you’re ready to install the new firmware update on your smartphone.

How to update Sprint Nexus S 4G to Android ICS 4.0.4 firmware:

  1. Download the Android 4.0.4 ICS beta firmware package and save it on your computer.
  2. Connect the phone to your PC using its USB data cable and select mount storage mode.
  3. Now you need to take the ICS firmware zip and place it in your phone’s SD Card.
  4. Disconnect the phone from the PC and power it OFF.
  5. Now, as the phone is turned off, we need to enter recovery mode and to do that you need to press the Volume Down key button and then the Power button.
  6. The recovery mode screen should load and after that is complete you need to select ‘wipe data/factory reset’.
  7. Now select ‘Wipe Cache partition’ and then your device should reboot, if it doesn’t do that action by itself it means that you have to do it. Power it back on recovery mode.
  8. Go to Advanced Options and select ‘Wipe dalvik cache’. Select ‘++Go Back++’.
  9. Now you need to select the option that says ‘install zip from SD card’ and then select the one titled ‘choose zip from sd card’. Point it to the ICS 4.0.4 firmware package you’ve downloaded at step 1. Select it and then wait until the update is completed.
  10. When the firmware updating process has been completed, your Nexus S 4G by Sprint should reboot but, if that doesn’t happen then you need to do it manually by selecting the option that says ‘reboot system now’ via ‘Go Back’.

That should do it, your phone will reboot and after its home screen successfully loads it should sport the new beta version of Android 4.0.4 ICS firmware. If the device doesn’t load or if something doesn’t look quite right and the ICS hasn’t been installed then you will have to repeat all the instructions listed above, as something might’ve gone wrong and not all files have been copied or you might’ve skipped a step.
