Update Samsung Galaxy S 4G T959V with Slim Bean ICS Firmware

So here is some Ice Cream Sandwich taste for Galaxy S 4G users as here is a fully-functional custom ROM for them from XDA. It is not an official upgrade as Samsung hasn’t announced any update for it but I advice users to upgrade as there is no upgrade news coming in near future.

Important Note: Although, we have taken the ROM link from a very reliable developer(XDA-Forum), yet go for this upgrade at your own risk as neither this site nor the author would be responsible for any problem in upgradation. However, this happens rarely. Also you would lose warranty of the hardware(if any).

The upgradation Process has been divided into two parts:

  • Pre-Upgardation.
  • Final Upgradation.

Please follow all the steps given below in the order they are given and donot skip any step in between.

Pre-Upgradation

Follow these steps with a little care. If you have any problem, feel free to ask-

  1. First of all check the phone version. It should be Samsung Galaxy S 4G T959V only (Check at Settings> About Phone). Do not upgrade if you have some other version.
  2. We advice you to take a backup of your existing ROM by using Nandroid Backup and Restore App from XDA.
  3. You can also take backup of some important data such as SMS, Contacts etc.
  4. Make sure that your Galaxy S 4G is at-least 85% charges. If it isn’t, we advice you charge your phone first.
  5. Next, disable all the anti-virus on your Device. Also uninstall all the Kies from your computer.
  6. Now enable USB Debugging on your cellphone (Option available at Settings > Applications > Development > USB debugging ).

  7. Your device is now ready to be upgraded.

Final Upgradation

  • First of all, download the official ROM for Samsung Galaxy S 4G T959V from the  developer’s page on your PC. Also download the Google Apps package.
  • Now connect your phone to PC via USB cable and copy both downloaded files on SD Card of your Phone.
  • Now turn off your phone and reboot it in ClockworkMod Recovery. This can be done by pressing and holding Volume Up+ HOME  Button all together.
  • Now from the options available on the screen, Select “wipe data/factory reset” and then further select Yes when prompted.
  • Now, you need to select the Installation zip file from sdcard(one you’ve copied from PC). For this select “choose zip from sdcard” and then select the ROM package from SD card.
  • Repeat the same step for Google Apps package.
  • When the installation is complete, go back to main menu, and select “reboot system now” and it will

With this you’ve successfully upgraded to Jellybean on your Samsung Galaxy S 4G T959V. Enjoy 🙂
