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 method

Here’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 required Root 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.

      1. hi, i cant find the right file to download, my build number is FROYO.BOJS5 and i cant find a similar download link for the .tar files. any help would be appreciated! had it rooted before but it went off to repair and came back with froyo 2.2 and auto-updated to 2.2.1 when i connected to my laptop. very annoying lol

    1. if your running a late model of windows, when you unzip the file another .zip file will appear. This is the .tar file. windows see’s it as a .rar file but load it into odin and it will work

  1. I have a Samsung vibrant, it only has Android 2.2 will it still work? If so, what CF-Root file will i need? (Build number: FROYO.UVKA6)

  2. Will this method still work if the phone has 2.2, not 2.2.1? Also, will it work on a Vibrant or just the GT-i9000?

  3. Yes! this worked on 2.2.1 Galaxy S. Finally a rooted phone. tried so many other ways, Thanks very much.

  4. That 2nd link for CF-Root is to a forum thread with over a 100 pages of posts. The list of specific ROM versions does not include the latest pure stock Froyo 2.2 which is KA6. Seriously, trying to wade through that thread is nuts.

    1. You don’t really need to go through the thread. The links are all included in the first page of that thread. You might have to wait for the latest KA6 for a day or two before it’s rooted with CF-Root.. ( I haven’t checked, don’t have a Galaxy S nowadays )

      1. KA6 is the 2.2 release on the T-Mobile Vibrant. It’s been out over a month. The 100 pages of posts is is an indication of all the problems folks have had, partially due to loading the wrong version of CF-Root. Just a cautionary note.

  5. thanks allot had heaps of trouble then found this site had a bit of trouble then realised i needed to hold the down button to put into download mode then realised i needed to close and re open the program for it to work absolutely genius thx

  6. tryed this. odin failed then disconnected phone and it bricked (i think) shows a phone …..! …. computer

  7. i dont know which cf file to download i have firm 2.1-update 1 baseboard T959UVJI6 Build Eclair.UVJ16 help please

  8. *edited from earlier* hi, i cant find the right file to download, my build number is FROYO.BOJS5 and i cant find a similar download link for the cf files. any help would be appreciated! had it rooted before but it went off to repair and came back with froyo 2.2 and auto-updated to 2.2.1 when i connected to my laptop. very annoying lol. baseband is I9000XXJPY. maybe im looking for the wrong thing, please help me : )

  9. I can’t find the right CF-Root Package. My Firmband is I9000XXJQ1 and I seriously can’t find the right one. And one more thing, I have Samsung Galaxy S with Android 2.2.1
    Some one please help!

    1. Sorry for my last message, I meant that my Baseband version is I9000XXJQ1… Please someone read my other message and help me!

  10. did everything as instructed was going find the firmware update was successful the phone rebooted but it is stuck the first part of the reboot with galaxy s gt i9000 on screen constantly i used
    CF-Root-JP6-v1.2-Busybox-1.17.1 also tried CF-Root-JPM-v1.2-Busybox-1.17.1 and had the same problem any idea’s where i what went wrong?

  11. I try to root my Galaxy s 2.2.1 with CF root Root\CF-Root-XX_OXA_JVK-v2.4-CWM3RFS.tar
    After that it gave me the following messages but the phone never boot,it keep going off and on. Can you help me out or what can i do to get it working back. Thanks.

  14. Hi,

    Great stuff Imran! However, I think it should be build version and not baseband version, right? I have baseband: I9000XXJPY and Build FROYO.XWJS5.

    /M

    1. Will this work on a Samsung Galaxy S Fascinate SCH-I500, 2.2.1, Froyo? I have tried so many that say it will work for the 2.2.1 Froyo but it never works for the SCH-I500.

  15. First–thanks, Imran, for the helpful tutorial. Original Froyo 2.2.1 on Vzn Galaxy S SCH-i500 now booting into i9000, boots through to logo, then goes dark. I’m stuck. Can you suggest the next step?

    1. If it’s not booting up, the first step I’ll suggest to you is to boot into recovery and wipe cache etc. If that doesn’t help, try reflashing the ROM. Let me know how it goes

  16. Update on the previous question: Getting an error message on reboot screen: E: can’t mount /dev/blocki/mmcb1k0p1. All this started when I tried to root. Can’t get to SD card with dark screen . . . .

      1. OK–I have not a clue how to reflash the ROM. Can you point me in the right direction?

        I have flashed

      2. OK–I have not a clue how to reflash the ROM. Can you point me in the right direction?

        I have flashed Stock-1500-VZW-Recovery.tar and have Stock-1500-VZW-Kernel.tar waiting. Avoided everything but PDA. Your help is appreciated more than I can express. I feel like I just got positive news from a biopsy test.
