How To Install Android 4.0.4 ROM on your Galaxy S I9000

Important Note: If you are on CM7, MIUI or any ICS (Android 4) based custom ROM, you can skip steps 2 and 3 below. If unsure of what ROM you are on, follow all the steps.

  1. Remove sim card lock, if you have set it earlier. Go here: Settings » Location and Security » Sim card lock  » checkbox should be clear (not selected).
  2. Flash the stock XXJVU firmware by using → this guide.
  3. Root XXJVU to obtain Clockworkmod recovery (CWM) by using → this guide.
  4. Download the latest version of the ROM from the original development page to your desktop.
  5. Transfer the downloaded zip file to the root of your internal SD card on your phone (don’t use microSD card).
  6. Turn off your Galaxy S and wait for complete shutdown (wait for vibration and check capacitive button lights).
  7. Then, boot into CWM recovery. To do so, press and hold these 3 buttons together: Volume Up, Home, and the Power button till the screen turns on, then let go of the buttons. You’ll boot into CWM recovery soon enough. In recovery, use Volume keys to scroll up and down and power key to select an option.
  8. Perform a wipe by selecting “Wipe data / factory reset” → then Select Yes – Wipe data/Factory reset on the next screen to confirm. (This will NOT format or erase your SD card contents)
  9. Now scroll to “Install zip from sdcard” and select it.
  10. Select  “Choose zip from sdcard”. Scroll to the file you transferred in Step 5 and select it.
  11. Now confirm installation by selecting “Yes — Install **your_rom_file_name**.zip. The ROM will start installing.
  12. Your phone will reboot into recovery after a few seconds, then continue installing the ROM. However, if it simply reboots into recovery the first time and does nothing, repeat steps 9, 10 and 11.
  13. After the installation is complete, select “go back” and then select “reboot system now” to reboot your phone.

Ice Cream Sandwich Android 4.0.4 is now up and running on your Galaxy S i9000. Follow the development page to get the latest updates on the ROM. Share your thoughts and experience on the ROM in the comments.
