I meant kernel. If you mean turning root on and of as you please I'm not sure but with CF-root you only flash that kernel for root privileges where as s2 root you have to flash an insecure kernel then root then flash original kernel afterwards.
[Galaxy S II Themes and Apps] pilotair:
I own an S2 and have had:-

Already sent it over to Samsung Repair centre..

1. Voice call problems (Been told it was solved but it wasnt, so I have to send it back)

2. Camera Problems (solved when sent back to samsung)

3. MHL HDMI adapter connectivity problems.

4. Samsung Service centre really wasn't of any help!

Overall it's a good powerful phone but it's design problems makes me hates it and the lack of professional support from samsung makes me hate it's brand!

goodluck mate!

Anyone had an luck finding a insecure UHKI1 kernel for SGS2 Int. version?
[Galaxy S II Themes and Apps] ctomgee:
Any insecure KI2 kernel will work for you.
[Galaxy S II Themes and Apps] Ray1:
Hello,

i have rooted my sgs2 using this method about half a year ago.

now i'm thinking of unroot.

previously i use odin to flash an insecure kernal, then root.

after rooting, i flash back the secure one to remove the yellow triangle.

now i'm on the secure kernal.

do i need to flash back insecure kernal to use the unroot program?

or i can proceed using the secure one.

---------- Post added at 11:48 AM ---------- Previous post was at 11:39 AM ----------

Opps, just used the search function for this thread.

not that user friendly, but anyway got my answer.

the insecure kernal is need for both rooting and unrooting.

but kinda weird, since my phone already rooted, why still need insecure kernal that grants "temporary" root access? confusing...
[Galaxy S II Themes and Apps] minahlepak:
How do I know which insecure kernel to use?

Mine says:-

Kernel version

2.6.35.7

se.infra@SEI-43#2
[Galaxy S II Themes and Apps] daxie:
looks pretty easy, does this work on the Sprint Epic 4G Touch too?
[Galaxy S II Themes and Apps] ctomgee:
Not with the kernels linked in post 1. You really should not be looking in this forum for firmwares, kernels, or rooting methods if you are an Epic 4g Touch user. They will not work for you at best, or totally bork your phone at worst. The Epic 4g Touch has a separate forum. Go there.
[Galaxy S II Themes and Apps] Beso:
Is there anythink else needed to do or just download S2Root_1.5.1 and plug SGS2 to PC?

What that means "Flash Insecure Kernels to you device". How do I do that? Is it necessaryto do it?

I Have BUKJ3 version.

Please help
[Galaxy S II Themes and Apps] jonny_ftm:
I won't use this method anymore. No new insecure kernels developed and would have trouble to unroot.

Just use CF_Root (since in both cases you have to flash a Kernel, so no advantage here). You would be able to flash back your original kernel if you like and one is available in intratech topic

I'd also upgrade to ICS since it's officially out for most people
[Galaxy S II Themes and Apps] lyriquidperfection:
I am currently in the process of developing some insecure kernels for use with this Root method for the newer newer ICS releases. I am also developing some linux scripts to aid users with a new method of rooting which pre-roots a system image and repacks it as a full rom to flash in Odin. :)
[Galaxy S II Themes and Apps] jonny_ftm:
Would be great in fact for people wanting to root while keep as close as original and avoid CWM recovery for security reasons.

Well, even in CF root is still possible if you flash back the original kernel (will erase CWM recovery) but CWM Manger remains installed (but broken), so not a clean way
[Galaxy S II Themes and Apps] 77cats:
Looking forward to see your next kernels (especially a BVLPB). ;)

[Galaxy S II Themes and Apps] ski98020:
Hi, Sorry for being a complete noob but I really have to ask what do you mean by Enable USB Debugging and Flash an Insecure Kernel?

I am a brand new user of smartphone(No apple, no android) ever before. I found that many are rooting their smartphone but I dont really know the reason behind it. However, from the article (Why-Root-The-Samsung-Galaxy-S2), I have got an initial idea about rooting. Can you please recommend some useful apps that requires rooted phone? and also some beginners thread that is useful for people like me?

Cheers!

?root?

How can i see that my phone is rooted? my Kernel is I9100XWKE@-CL187*** root@DELL101 #2.

If not rooted can i use this to easily root my phone?

tnx for any reply!!:o
[Galaxy S II Themes and Apps] lyriquidperfection:
Try using an app that requires root access. If you get a superuser request, you have root!
[Galaxy S II Themes and Apps] Gohann001:

I also hope to get Galaxy S II in 10-15 days and first time I hear about insecure kernel !? Can we root our stock ROMs that comes with the phone ? If not, can you please post link in your first post to that insecure kernel with step-by-step instructions on how to do flash it on the phone. I am also sure that I will root with your app because it looks great and easy.

How do I know which insecure kernel to use?

Hi

How can I tell which insecure kernel I'm supposed to use?

My S2's details are as follows :

Baseband version : I9100TDUKF2

Kernel version :2.6.35.7-I9100TDUKF2

Build number : GINGERBREAD.DUKF2

Current firmware version : PDA:KF2 / PHONE:KF2 / CSC:KF2 (VAU)

Thanks in advance.
[Galaxy S II Themes and Apps] lyriquidperfection:
I dont think there is an insecure KF2 kernel for your device. Try the KE7 one this worked for me! :)

[Galaxy S II Themes and Apps] dantemaster:
Hi, first of all thanks for your great work!

One note about my experiences:

Although I have enabled usb debugging, ODIN could not flash the kernel.

The solution was to restart the phone in download mode.

Cheers, D
[Galaxy S II Themes and Apps] lyriquidperfection:
Oh crap forgot that step! Ill update the guide! :)
[Galaxy S II Themes and Apps] ctomgee:
Read post 1 again. THOROUGHLY.

EDIT to add: seems post 1 says it works with all Samsung devices, but the kernels linked are ONLY for i9100 and directly compatible devices. (so don't use them for YOUR device)

So if you can find an insecure kernel for your device somewhere, then it should work.
[Galaxy S II Themes and Apps] jcmarx:
Thanks man, but where would I go about finding an insecure/unsecure kernel? I have read through several posts of people tring different root methods and no one has posts success.

I have rooted several phones ( thanks to all the great walk thrus here) but Im not super tech savy. I can follow instructions but dont have the knowledge to do it on my own.

any help would be great, I have been reading the same for samsung illusion the same phone only the verizon paid version. No luck there either.
[Galaxy S II Themes and Apps] ctomgee:
Sorry, I have no idea where you would get kernels for the Proclaim. Definitely not here in the I9100 forum though. ;)
[Galaxy S II Themes and Apps] jcmarx:
Yah sorry about that I know some people get serious about forum ediquette but Ive tried in the general area and only posted here not because of the i9100 but because of the oneclickroot for all samsung post. Not sure where else to look or go just a person looking and grasping for info anywhere in hopes someone can point me in right direction

Anyways sorry for being in the wrong place...
[Galaxy S II Themes and Apps] lyriquidperfection:
Read the guide in the first post of this thread. Links are provided. ;)
[Galaxy S II Themes and Apps] ctomgee:
I wasn't saying that as a matter of etiquette, just that it's unlikely you'll find kernels for your device in a forum for a device different than yours.

He's not got an i9100, so the kernels linked in post 1 won't work for him since they're all i9100 kernels.

Edit to add: well, there are two i9100g kernels, and three m250 kernels, but my point is still valid. There are no kernels for HIS device.

[Galaxy S II Themes and Apps] kevinm2k:
Went through this method and although all the steps worked successfully with S2 root telling me it was successful and installed Superuser.

I still dont have root access, tried a few different programs.. nothing, tried a root checker program which confirmed I have no access.

Tried doing this 3 times, same everytime. Any ideas?
[Galaxy S II Themes and Apps] lyriquidperfection:
Please post your device model and ROM version so I can investigate further.
[Galaxy S II Themes and Apps] kevinm2k:
Model: GT-I9100

Kernel: 3.0.15-I9100XWLP7-CL340913

Android Version: 4.0.3

Build Number: IML74K.XWLP7

I'm on stock ICS rom.

I can't see where the SU binary is being installed - therefore Superuser is giving the message: "Failed to find currently installed su binary". When I 'unroot' it does say removing su binary but when rooting it doesn't say installing su binary.
[Galaxy S II Themes and Apps] lyriquidperfection:
Hi you need to flash an insecure XWLP7 Kernel in order to root your device with S2 Root. They can be found on a link by following the guide in the first post.
[Galaxy S II Themes and Apps] wuufer001:
I tried flashing back secure/original kernel,

tried it twice, the triangle did go away, but after that the phone will not boot.

since then i have flashed with the insecure kernel in order for the phone to boot properly.

is there something i did wrong?
[Galaxy S II Themes and Apps] Rekuja:
Titanium and Superuser keep telling me that my device isn't rooted.. I have flashed the correct insecure kernel and your software tells me the root was successful..

any idea?
[Galaxy S II Themes and Apps] Decepticaons:
Use the Odin method, its quick and easy and works every time. This method is great and the dev does awesome work. I just found Odin to be easier.
[Galaxy S II Themes and Apps] ctomgee:
Without more detail, I can only guess you flashed the incorrect secure kernel.
[Galaxy S II Themes and Apps] AndehX:
Odin method?

I have the same issue. Followed instructions to the letter, and superuser says fail when trying to gain root access.
[Galaxy S II Themes and Apps] Decepticaons:
You have to install that zip like 4 times. Keep doing it till it goes through.
[Galaxy S II Themes and Apps] AndehX:
Zip? the installation of this root doesnt involve flashing any zips.... what do you mean?
[Galaxy S II Themes and Apps] Decepticaons:
Do you are stuck in odin then?

[Galaxy S II Themes and Apps] A22AC:
so do we need to install CWM after that?
[Galaxy S II Themes and Apps] lyriquidperfection:
This is really for people who only want root access whilst retaining stock recovery. As recovery is part of the kernel CWM is often bundled with root access anyway so if you want CWM aswell as root then just flash a rooted kernel.

My method however is safer as you flash the stock kernel back afterwards where as a rooted kernel is exposed as they use a patched adbd binary which always runs as root.
[Galaxy S II Themes and Apps] stanley08:
Are the kernels on the first page for GB or ICS?
[Galaxy S II Themes and Apps] UnwiredDroid:
It supports other Samsung Android phones?
[Galaxy S II Themes and Apps] lyriquidperfection:
Yes it does as long as you have an insecure kernel for that device.
[Galaxy S II Themes and Apps] UnwiredDroid:
i still need to push an insecure kernel on it? Like the one from intratech?

insecured kernels for rooting

Find the insecured kernel repositories herehttp://d-h.st/users/LyriquidPerfection/?fld_id=2886#files depending on your present modem checking from your phone by browsing Settings >> About

Happy downloading :D

---------- Post added at 11:59 PM ---------- Previous post was at 11:55 PM ----------

After rooting please download original kernels from http://d-h.st/users/LyriquidPerfection/?fld_id=2886#files and flash through Odin to revert back to original kernel. By doing this you phone won't lose ROOT, your phone's root will still remain.

Any issues we are all here to support you...
[Galaxy S II Themes and Apps] ctomgee:
Context is important.

If you go back a page, you would see that zackwire has a Galaxy S Advance GT-I9070. Not an I9100. He was asking if this would work for his phone, and LyriquidPerfection said it would - IF he had an insecure kernel for his phone.

You provided a link to secure and insecure kernels which are ALL for the I9100. None of those kernels would work for him, as they are NOT for his phone.

EDIT to add: also - what does the modem have to do with the kernel? (Absolutely nothing)

EDIT 2: @zackwire - see this google search: http://www.google.com/search?q=site:xdaforums.com+i9070+root. Also, if by a "factory" kernel you mean you have the kernel that came with your phone, then it is almost assuredly NOT an insecure kernel. Samsung is not in the habit of providing insecure kernels on their phones out of the box.

You likely used the wrong kernel, since that kernel (KF5) is super old, and one of the first Gingerbread releases. If you haven't figured out what to do yet, I'd just say flash a stock ROM.
