So, you’ve already installed the leaked XXJVS Android 2.3.5 firmware from Samsung. And now as always, you want that root access to become great superuser of your Galaxy S, again. Well, good. We were using the XXJVR Root for the time being to root XXJVS, but now our favorite developer Chainfire has just outed his CF Root kernel for XXJVS too, which lets users root XXJVS firmware without any pains whatsoever and without any bugs — WiFi is working fine now, it was a problem with XXJVR’s root.
Before we see the download links and installation instructions, let’s go through boring compatibility notes and warnings:
[error]This guide is applicable only for Samsung’s Galaxy S international version (i9000) running on XXJVS firmware. Check your phone and firmware version and in Settings – About Phone. The model number has to be “GT-i9000” and the build number “GINGERBREAD.XXJVS” for the this root to be compatible with your device. If it’s not so, simply don’t try this or anything discussed here on your android device; in fact, don’t even think about it if you care about your android device.[/error]
[warning]The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to you or your device, we won’t be held liable. You only will be responsible, you’ve been warned!!![/warning]
Quick Instructions: Make sure you’ve XXJVS firmware installed, as I said above too. Download the CF Root Kernel and flash it using Odin by selecting the kernel’s .tar file in PDA tab. Keep Re-Partition un-ticked. That’s it.
It’s okay if you didn’t get the root method discussed above because a detailed guide too is available for you, just below. Btw, if you wanna see a video first on ‘how to flash root kernel’ — check this video, which shows flashing the root kernel of earlier firmware XXJVB.
Step-by-step guide:
- Download CF-Root kernel first. Filename – CF-Root-XX_OXA_JVS-v4.1-CWM3RFS.zip. Size 6.08 MB.
- Unzip the above file to a folder. You will get the .tar file – CF-Root-XX_OXA_JVS-v4.1-CWM3RFS.tar — inside folder. DO NOT extract the .tar file (even if you see it as a zip file, which it is not). You need to flash the .tar file using Odin to gain root access and install the ClockworkMod Recovery (CWM) alongside. (If you’re getting zimage, it means you’ve extracted the .tar file too! — and that’s not a right thing to do.)
- Use the Odin software you used while flashing the XXJVS. No separate download is required.
- Switch Off your phone. Wait for vibration to confirm complete switch off.
- Boot your phone in Download Mode — Press and hold VolumeDOWN+HOME+POWER keys together.
- Open Odin now.
- Connect your phone to PC now. You’ll notice “Added! !” message in the Odin’s message box in the bottom left.
- On Odin, click the PDA tab and select the .tar file you got in step 2 — CF-Root-XX_OXA_JVS-v4.1-CWM3RFS.tar.
- Make sure “Re-Partition” checkbox is un-ticked. Leave the “Auto Reboot” and “F. Reset Time” checkboxes ticked.
- Double check step 8 and step 9.
- Click the Start button on Odin to flash the CF-Root kernel.
- After the CF Root is installed, phone will restart automatically. When the
Galaxy S IIGalaxy S logo shows up on phone, you can disconnect the cable from phone. - Your phone is rooted now. That surperuser app is there!
That’s it. Thanks the Chainfire for this! And, if you like this article share it with friends and others who may need it.

I have installed on my Galaxy S 2.2.4 XXJVP the gingerbread I’m very pleased with the performance and performance of my galaxy. The battery life has doubled. I wonder what the benefits of version 2.3.5? But continue to say that there is something wrong with the 2.3.5 files
i have installed on my Galaxy S 2.3.5 gingerbread. after rooting, CF-Root-XX_OXA_JVS-v4.1-CWM3RFS, I’ve lost my data connectivity.
Wifi is oke
Update APN settings.

is this like lagfix on 2.3.5 XXJVS?

I’ve installed 2.3.5 XXJVS on my galaxy S, now I’m trying to root it. Before that, will my data wipe out after I root my device? Or I need to backup my data before start rooting my device?
Rooting won’t delete data. Go for it.
Hi Kapil after STEP 11, the text box status in ODIN says ‘setup connection…’ seems to be stucked. Can I just close the ODIN and load it again. Do I need to unplug the SGS?
Yes, unplug phone and close Odin too, without any worry.
Hi Kapil, I unplug the phone restart ODIN. But no connection detected anymore in ODIN. Can i shutdown my phone and boot to download mode again. I ask because I am under the impression that during the failed attempt earlier, I was thinking that there were files invoke already into the phone in the middle of the process and might cause something haywire.
You need to boot into bootloader mode again. Odin recognizes it one per boot. So, remove battery and boot into bootloader mode again.
Hi Kapil, its detected now. I reinstalled the USB drivers downloaded in this post. Previously it was detected as COM 21 not it is detected as COM 11. I will start again.
thanks for the early response.
Hi Kapil, Sorry need to ask you again. I still encounter the problem. Im stuck in SetupConnection .. in the ODIN Status window. any idea?
Kapil,
Thanks mate. Works fine now.
More power to you and ChainFire. Keep up the good work.
Cool 🙂

Is this for the Galaxy S and the Galaxy S II ? Start of the text mentions Galaxy S but step 12 it says Galaxy S II.
Oops!
This is only for Galaxy S running XXJVS firmware. For S2, there are other root methods we’ve covered. Which phone do you have and what’s the build number?
he meant about the logo that u said… about s2,
and thank for the great tutorials … keep it up
Oh ok… 🙂

is there a way of rooting it without a computer? for some reason, now ive installed jvs i cant boot into download :/
ive got a jig that i can use but this is strange..
Download the kernel’s zip file from root guide on your mobile, extract it using Astro file manager, then download mobile odin from android market and flash the extracted .tar file of kernel using mobile odin to root.
You have to be rooted to use this app!!!n

So I successfully performed this upgrade from a Bell 2.2 Vibrant and it all worked fine. However, it appears that this radio doesn’t support the Bell frequencies in Canada. I have no voice or data at all. I understand I need a modem selection from the Captivate to work on Bell frequencies. I have that file in .zip format for CWM. More unfortunate is the fact that no matter what I try to flash in CWM all I get is a (Status 7) error in CWM. Why does this method break CWM so I cannot flash any file? I’ve tried multiple versions of Cyanogenmod roms and this modem and they all error the same (Status 7) error. Kies does not detect this as an upgradable phone anymore and I know of no way of going back to the old 2.2.

Hi Kapil, just wonderin.. if my phone is rooted via the SuperOneClick method, do i still need to root using this method once XXJVS is flashed ?
Thanks in advance.
You can use the above to install clockworkmod recovery. If root is what you only needed, then the above won’t help you, you’re already good.
Hi Kapil,
Another quick question.
I used OneClickLagFix, which i think created a ext2 partition,
is it alright if i still proceeded with the guide above ? or should i remove the partition first ?
sorry, kinda lost here a little.
Thanks.
Yes, you are good to go, that shouldn’t be a problem.

Hi Kapil,
im on Galaxy S GT-I9000 running official 2.3.5 NEJVK from Three network UK.
*#1234# reveals:
PDA: I9000NEJVK
PHONE: I9000NEJVB
Will this rooting method work on my device?
If no, can you recommend an root method using CF Root Kernel from Chainfire!
One last thing, (if i can ask) can i install 2.3.6 without rooting?
Thanks in advance
You can install Android 2.3.6 without rooting. Only if you want to install Android 4.0 Ice Cream Sandwich, you would need Root and Clockworkmod (CWM) Recovery installed.
Use this guide to install Android 2.3.6 – nerdschalk.com/galaxy-s-gets-official-value-pack-firmware-xxjw4-includes-touchwiz-4/ Use this guide to install Android 4.0 – nerdschalk.com/galaxy-s-gets-android-4-0-based-aokp-rom/
Also, I couldn’t find a root method/tool specific to NEJVK build your Galaxy S has, so install the Android 2.3.6 as linked above, and root it if you want, although it’s not necessary.
Thank for you help Kapil. Will install 2.3.6 and give you feedback later
