How to Root Samsung Galaxy S with Android 2.2.1 Froyo


A lot of users have been sending me in messages lately for a guide on how to root a Samsung Galaxy S with Android 2.2.1 Froyo. The one click root method doesn’t work anymore so you have to put in a little more effort to root your phone now.

Samsung Galaxy S Android 2.2.1 root methodHere’s what you need to get started:

Also remember to back up your data before you do this. Disable any lag fixes. This is best done on a clean installation of the OS so if you can, back up your data and do a factory reset to avoid any issues what so ever. Done? Here it goes:

  1. Start Odin. Click the PDA button and select the CF-Root.tar file from the zip file you downloaded (extract the zip file after you download it). Once again, the downloaded file depends on your Android Baseband version. Check the ending letters of your baseband version in the Settings > About page. It should end in something like JPH or the likes.Root Samsung Galaxy S 2.2.1 Odin CFRoot
  2. Uncheck re-partition in Odin. Don’t put anything in PIT or any other field. Only PDA is requiredRoot Samsung Galaxy S 2.2.1 Odin CFRoot
  3. Now you have to put your phone in download mode. Turn off your Galaxy S. Hold down the power button, volume down button and home button until it shows Downloading… as shown below. The phone is now in Download Mode now. Connect the USB cable to the phone.Root Samsung Galaxy S 2.2.1
  4. If your phone is connected properly, Odin will highlight that the connection.Odin3v1.302_thumb (1)
  5. Now click on start and wait for the process to complete. Your phone should automatically reboot and will be rooted now. To confirm, check if you can see the Superuser icon.

    I have 2.2.1 and I have been trying to root the phone or atleast flash it through Odin. Never works for me. My cpu doesn’t recognize download mode whatsoever. Yet if I where to use odin and hit Kies Mini on my Samsung Odin recognizes the device.
