install the XXJVU update on your Galaxy S

The latest release of Android™ Gingerbread available for the Samsung Galaxy™ phones is version 2.3.6, firmware XXJVU. This upgrade brings only a few changes, such as Lock Screen from Galaxy Note®, a photo editor app from Galaxy S®2 and Ice Cream Sandwich Special Face Unlock feature, in addition to the usual Android™ 2.3.6 Gingerbread features.

For most users, these changes are important enough to flash the ROM on this version; however, there is a more valuable reason why it is important to install XXJVU on your Galaxy S®. The Ice Cream Sandwich (ICS) platform requires this update. So if you want Android™ 4.0 ICS, you have to upgrade to version 2.3.6 and have the CWM (Superuser access) root in your phone.

The instructions below explain how to install the XXJVU update on your Galaxy S® and how to add the CWM, which is necessary for an ICS upgrade.

Back up your Phone:

Remember all the data in your phone might be deleted, so be sure to back everything up including:

  1. Photos and images
  2. Contact list, SMS and other communication, such as emails
  3. Music and Video files
  4. Applications and Internet settings
  5. Bookmarks and stored pages
  6. All data stored on your SD card as a flash drive

Prepare your Phone for the latest upgrade:

  1. Before you upgrade, check to see if you have working drivers in Windows® 32 bit (x86)  and 64-bit (x64) so your smartphone can be properly connected with your PC.
  2. If you have installed the PC software application Samsung® Kies, be sure to exit it before using flash this ROM, or anything with odin software.
