The last month — March ‘11 — was quite hectic for Samsung Galaxy S as the phone tasted its first Gingerbread ROMs by way of leaks — XXJV1 and XXJVK. Obviously, there were custom ROMs released too, that were based on the leaked ROMs. We tried the ROMs and felt delighted too. But all that summed up to the fact that we had put our Galaxy S to lots of trials with Android 2.3 and it became imperative that we shared with you an article which tells about ‘how to revert back to Android 2.2 nice and safe’.

Also, those of you who are still on Android 2.1 (Éclair), use this guide to install pre-rooted Android 2.2 on your phone so that you can try the Android 2.3 stuff or other custom  ROMs.

So, here it is. Although there are many ways — I mean, the ROMs, both custom and stock — I’ve picked up the EZRom which I’ve used quite a few times and looks good to me. The EZRom uses a different Odin than what we’ve been using for so long, Odin3. The new Odin is called EZOdin and it’s different looks-wise. The EZBase ROM will install the following stuff to your phone:

  1. Android 2.2 (Froyo) – JVE
  2. Phone’s already rooted
  3. Apps — SuperUser, Titanium Backup, ROM manager, etc.

It’s plain and simple and already roots your phone, so, I like it.

EZRom installation video:

Although there is a very informative guide already available (Get the .PDF file here) from the developer himself, but here’s my instructions set:

  1. Download required files [PREMIUM HOTFILE LINKS]:
    1. EZbase-CSC-XXJV1.tar.md5
    2. EZbase-PDA-XWJS3.tar.md5
    3. EZbase-PHONE-XXJVE.tar.md5
    4. EZodin
    5. EZbase.pit
    6. 64bit Samsung USB Drivers (No need for Kies)
    7. 32bit Samsung USB Drivers (No need for Kies)
  2. Don’t extract any of the file. Don’t play with them in any way.
  3. If you don’t have drivers installed or just in case want to re-install them for safety, uninstall them first and reboot your PC. The, install the drivers from step 1.6 or 1.7 above as applicable to your windows.
  4. Switch Off your Galaxy S. Wait for vibration to confirm complete Switch Off.
  5. Put your phone into ‘Download Mode‘ using the three button combo — “Volume DOWN + Home key + Power Button”. Don’t connect it to computer.
  6. Open EZOdin. [Looks cute than Odin3)
  7. Connect your phone to PC now. You should get the “Added” message in the message box.
  8. Check the Re-partition button first of all.
  9. Keep the Auto Reboot and Reset Time buttons checked too.
  10. Keep these boxes UNCHECKED — EFS Clear and Bootloader Update
  11. Hit the PIT tab and select EZBase.pit file at step 1.5 above.
  12. Hit PDA tab and select file at step 1.2 above — EZbase-PDA-XWJS3.tar.md5
  13. Hit Phone tab and select file at step 1.1 above — EZbase-PHONE-XXJVE.tar.md5
  14. Hit the CSC tab and select the file at step 1.3 above — EZbase-CSC-XXJV1.tar.md5
  15. Double check everything above. The EZOdin window should look like the screenshot at the top.
  16. Hit Start button. this will flash the EZRom on your Galaxy S. phone will boot up automatically.
  17. Check out your phone’s version here — Settings – About Phone.

That’s it.

      pretty good ROM and works beautifully. It’s fast and has good battery life
      too. Search this website for xxjvq to find download links and installation
      guide.

      Btw, try playing the mkv files with mvideo player.

    Hi Kapil. I have a Samsung Galaxy S GT-i9000. It is stuck in a boot loop just flashing the Samsung start-up screen. I have followed your excellent instructions to the letter and the flashing process works fine with no errors. However, the phone is still stuck in the boot loop. I can get into recovery mode and download mode no problem. Do you have any ideas? Anything I can check? Thanks – Matt

      No need to go back to 2.1/2.2. Just disable the lagfix, if it’s enabled — search our site for guide on that.

      After disabling lagfix, install CM7 using the guide linked in the guide above.

      And then, continue from next step — after installing CM7 — in this guide.

      Oh, no idea. But my best guess would be that while you were download the firmware/rom, your download got corrupted.
      Anyway, EZRom thing is old. Just install the latest firmware XXJW4 on your Galaxy S – nerdschalk.com/galaxy-s-gets-official-value-pack-firmware-xxjw4-includes-touchwiz-4/
