I have to confess that I have not used this method myself but a few posters have.

Something else you could consider is flashing a stock Samsung ROM, including a stock kernel, that takes you away from the LPH, storage problem, kernel and then root your phone using the new, stock. kernel details.
Thanks ironass. But i think i have just found an issue with the kernel you told me to use as an alternative. My camera no longer works. It can take pictures but the screen is just completely black, so i can see what im taking a picture of. Anyone experienced this before? Any fixes out there??

I don't have any other apps that require the camera. But i can't watch videos either. I did see another thread about the same problem. I think the problem is the kernel i flashed is for 4.0.3 but im on 4.0.4

I thought that the original stock kernel that came with your Samsung, stock, firmware that you wished to root was, "3.0.15-I9100BVLPH-CL969772"?

This, as far as I am aware, is the stock Orange UK firmware, released in August on Android 4.0.4 for CSC code ORA. Therefore the kernel, LPH, is Android 4.0.4 compatible. The only problem with the CF-Root kernel for LPH is that it is unable to mount secure storage and this may be causing your issues.

This is why I suggested that you flash a different stock firmware, whose root kernel does not have this problem, say, XWLPY stock firmware, and then root it with the LPY CF-Root kernel.

This would mean that you have the latest and most up-to-date firmware currently available and without any Orange bloatware. Since rooting a phone means that you cannot update via the Samsung Kies PC Suite anyway, you have nothing to lose.

Thanks ironass. As you can probably tell im a complete novice at this. I don't have access to my computer at the moment. Is there any specific steps i need to take.? From what i gather i need to unroot the phone with a different stock kernel. Then root again? Correct me if im wrong. By the way im sorry for asking all these questions!

Don't worry about asking questions, this is not XDA, someone will always point you in the right direction.

Flash the stock firmware recommended by Ironass. It will come with a stock kernel and the phone will reboot as stock and unrooted. If you want to root again then flash the CF kernel that matches your stock kernel you've just flashed with flashing the stock ROM.

The easiest way to unrooted and go back to square one with a stock phone is to flash a stock ROM using Odin.

Here is a link to the CF kernel for the XWLPY stock firmware you flash. Flashing this will give you root again.

Don't know where you gathered that from!

No need to un-root before flashing a stock firmware as it contains a stock, un-rooted, kernel.

You are right to be cautious sgdcf.

I see from your details that you have the GT-i9100, International, version and that you are running the OLB CSC code for Msalaysia, Thailand, Singapore, the Philippines and Vietnam.

Your firmware is the old LPA firmware from June this year.

This has a kernel code of LPB which can cause problems when rooting as the CF-Root kernel for LPB does not mount secure storage.

Therefore, in order to root your phone, I am going to suugest that you update your fimware to the latest for your CSC code. Currently, this is the LPF firmware.

You can either update by connecting your phone to the Samsung PC Suite, Kies or, if this option is not available to you, you can flash the above firmware that I have linked you to, via Odin and follow the instructions under the heading, "My firmware is not eligible for ICS yet but I want it now!", in post #1, here.

Either method will install the latest Samsung, stock, un-rooted, firmware to your phone and when this is done, you can post your new kernel details and then set about rooting your phone. This I believe to be the safest option in your case.

Thanks Guys, my S2 is now unlocked and I'm in the process of carrying out a nandroid backup, will install TB Pro and root explorer shortly.

The next big step for me is installing a custom JB rom, wish me luck ;-)

Any recommendations on a good stable one to try first ?

Thanks again

It depends on what your current stock kernel details are...

Once you have ascertained which kernel version you are currently running you will need to go here.

Search posts #3, #4, #5, #6, #7 and #8 for a CF-Root kernel that comes closest to matching your current kernel, i.e. KG1, KF3, KI1, KK5, LPQ, LPS, etc:

For instance, if you are currently using 2.6.35.7-I9100JPKJ2-CL655700root@DELL143 #2 use CF-Root-SGS2_XW_XEF_ KJ2 -v5.0-CWM5.zip. If there is not a kernel which matches the letters and numbers in bold just go one number up from yours. ***(See below for number only kernels)

That is not your stock Samsung kernel details. Those are for a rooted kernel. Without knowing your stock kernel, I cannot match or advise you about your root kernel.

As your stock kernel does not follow the usual convention of letter and numbering then choosing one that matches your build number is correct.

Hello and welcome to Android Forums DavidTan!

If you are experiencing problems with your stock kernel then the easiest solution is to flash a custom kernel, such as Siyah or Dorimanx as these should rectify the situation.

Default Yellow Triangle

Hey guys,

So I tried to root my samsung galaxy s2 i9100 2.3.3 on odin, but I've done something wrong and the yellow triangle keeps appearing when I try to turn it on.

I can access recovery and download.

I think I have to flash a siyah kernel through odin to get it going but am uncertain which one or where to get it.

Could not find one on sammobile.

Any help would be appreciated!

Hello and welcome to Android Forums nikkib7854!

Have you tried the wipe mentioned in post #1?

Are you sure that you used the correct CF-Root kernel that matched your original stock kernel details, as per post #1? Could you post your original, stock, kernel details and the details of the kernel you used to root in case there is a mis-match.

I don't think I used to right CF, that is why this happened.

I also followed the instructions from a different website not this one!

the CF was CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5

I am not certain what the kernal was beforehand, and stupidly can't check it now, such a n00b!

Oh dear!

Here we go... We need to flash a stock firmware for you in that case, to get you up and running and to be able to re-root.

I'm guessing that you don't have your CSC code details and so all we can do, as you cannot boot up, is to flash a generic, stock, Samsung, firmware to your phone.

Was your phone running carrier branded firmware?

Which country are you in?

Do you need a language other than English?

This is the stock Optus firmware, Android 4.0.4, for the GT-i9100. You will need to download this and flash it with Odin, following the instructions under the heading, "My firmware is not eligible for ICS yet but I want it now!", in post #1, here.

This will put the Optus, ICS, firmware on your phone with a stock un-rooted kernel. You can then follow the steps in post #1 and #2 of this thread to root.

Rooting does not unlock your phone.

No, you were told wrong I'm afraid. You will need to either obtain the unlock code from your service provider or take it to your friendly local mobile phone shop.

Sorry again, my phone is fixed now, but after flashing that firmware my phone has reverted to this..

samsung galaxy s2 GT-i19100
android version. 4.0.4
Baseband version. i9100XXLQ6
kernel version. 3.0.15-1056084
dpi@DELL168 #3
SMP PREEMPT Wed Aug 22 22:55:24 KST
2012
Build Number: IML76D.XWLPW
Pda:I9100XWLPW
PHONE:I9100XXLQ6
CSCI9100OPSLP6

I'm trying to Root it now but because of these details am having trouble. I did notice in post rooting 4.0.4

Ironass you said to try LPW I can't seem to find a CF Root for that, only the firmware u just gave me. Any ideas where I can find this?

Hey guys,

I've been running Siyah 5.0.1 with Vanilla Rootbox, but I wanted to see if I could get better battery performance under 4.1.4 as tha was what I was getting the best batterylife on before, however, when I flashed the kernel now it doesn't boot. Just gets to the gok logo then blank. I can get to Recovery, but that's about it.

Any ideas?

Edit: It appears that Rootbox flashes its own kernel. So I'm assuming there is no way of getting a siyah kernel to work with this rom?

Have you tried wiping cache and dalvik in Recovery, as per post #2?

Failing that, post on the, "Rootbox JB ROM", thread and see if they have any ideas.

Hi

I am using Rootbox 3.2, and also Dorimanx Kernel.

After flashing the ROM, I then flash the kernel in recovery before restarting the phone.

Boots up fine on Dorimanx.

You may want to give this kernel a try, as it has lots of battery tweaks.

On your phone, go to... Settings > Applications > Developement > USB debugging and check the box.

(On ICS ROM's.. Settings > Developer options > USB debugging and check the box)
and that you are turning light blue...

Connect your phone, still in Download mode, to the PC using the USB lead. If you have successfully connected to Odin you should see the ID:COM box in Odin turn yellow or light blue, (depending on which version of Odin you are using).

Question

Hi, I am really new to the rooting subject, so I am worried because there's a chance to cause some damage and I really need to do this because I have to record some videos of the Smartphone screen with Screencast that requires root.

Smartphone model: Samsung Galaxy S2 GT-I9100
Kernel version: 2.6.35.7-I9100UHLB2-CL966147
Build number: GINGERBREAD.UHLB2

What CF-Root do I choose?

Thanks

Hello and welcome to Android Forums BrnTsw!

The UHLB2, Gingerbread, build is very old, February 2012, by Android standards and there has been an update for your CSC code, which I guess is ZTO, in May 2012, to ICS, Android 4.0.3.

Since there is no CF-Root kernel to match your existing, stock, kernel of LB2, you could upgrade your firmware, using either the Samsung Kies PC Suite or Odin to the latest Android 4.0.3 and then match the new stock kernel with a CF-Root version.

Well here's the thing, I'm developing an application that is olny being tested on Android version 2.3, so I'm not sure if it's gonna work on ICS. There's no other way? If there isn't, if I install the ICS, is it easy to re-install Gingerbread if I need? Sorry for this questions, but I have to finish recording the videos of my app tomorrow.

You could try using CF-Root kernel LA4. That may work for you.

If you move up to ICS you will have to manually flash your existing Gingerbread firmware, UHLB2, after first doing a Factory Reset and a re-installation of all your app's and settings.

You could try rooting with the LA4 CF-Root kernel and if that does not work you will have to flash your existing firmware, with it's stock, un-rooted, kernel, using Odin.

There are 2 LP7 Cf-Root kernels... XW_XEN_LP7 and DX_XTC_LP7.

I would start with the XW_XEN_LP7 first.

Sounds like you may need to re-calibrate your battery.

Just double checking...

Could you post your, "Version", details...

This will give you 4 lines of information about your phones firmware and CSC code, etc: You should make a careful note of all this information and keep it somewhere safe.
and your original, stock, kernel details...
