kies updated me from KF3 to KI4. Lost all my root stuff. adverts everywhere! grrr

android version 2.3.4

2.6.35.7 ......... XWKI4

which kernal do i use... i see some on front page but these date back to may?

XW_NEE_KI4-42-V4.2 and V4.1

is it one of these or is there another one?
[Galaxy S II Original Android Development] DarkNiz:
I'm not. I just want the kernel. Can I still install it?
[Galaxy S II Original Android Development] CamoGeko:
I'm not sure why you wanna do it, but go for it. Either it will boot or it won't, if it doesn't start just go back to ODIN and flash back your current kernel.

Hello Chainfire thanks for the good work... However is it possible for you to make a root kernel for the I9100G? With DZKI1 firmware/kernel ??

The firmware and kernel are from here :)

Kernel

Hello. I just got the AT&T SGS2 today with Kernel Version 2.6.35.7. Baseband of I777UCKH7 and build number GINGERBREAD.UCKH7. Question: Is the KH4 too far away from my KH7 to flash. Also does it make a difference that I am using SGS2- I777. If it does could you create one for this version. Thanks ahead of time
[Galaxy S II Original Android Development] Naka_Timo:
After flashing, the CWM and the super super is not in my screen. Seem like got flash like never flash and tried a lot of time. Root direct, press on the mount read and write,nothing happen.

Hi,

What version used to make root the galaxy with s2 rom GT-I9100 / I9100UHKI1 / 2.6.35.7-I9100UHKI1-CL550245se.infra SEP-40 @ # 2 / gingerbread.UHKI1 of Brazil?

Thanks.
[Galaxy S II Original Android Development] CamoGeko:
If you're running 2.3.4 then try KI2.

[Galaxy S II Original Android Development] Metallan:
Ok, so my Kernel Version says 2.6.35.7-I9100UHKG7-CL417954

According to the guide, I should be using KG7, but it comes to my attention that it says "MUL" while most others say "OXA" or something similar. Does this not matter at all? Is that "MUL" supposed to match something on my Kernel version? Can I just ignore and nothing will happen?

Any help would be appreciated.
[Galaxy S II Original Android Development] Naka_Timo:
Bro chain fire...could u help..i have flash ki8 v4.3 cwm4.tar...it doesnt seem to work despite various attempt..

I do not c the super user icon and the cwm icon on my phone.. N my root loader..cannot mount the phone..

Pls give some advice..
[Galaxy S II Original Android Development] CamoGeko:
Just go ahead and flash it, it will work. Or better yet, upgrade your firmware. ;)

Transmitted from a Galaxy far far away via XDA telepathy.
[Galaxy S II Original Android Development] Metallan:
Thanks for the reply.

Actually that's the latest version that my KIES allows me to update to. I'll go ahead and flash it. Wish me luck.
[Galaxy S II Original Android Development] MakeW00t:
Really noob question that probably has been answered in this thread but its hard to search with mobile so.. If my KIES tells me that there is an update for my phone, what happens if I update? I probably loose root etc? But does it brick my phone?
[Galaxy S II Original Android Development] CamoGeko:
You will most likely loose root, but don't worry because you can just flash the corresponding CF-Root kernel afterwards and voila... you will have your root back.

With regards to bricking.... you have to be galactically stupid and utterly without any common sense to actually brick an SGS2.
[Galaxy S II Original Android Development] donalgodon:
There are no optimizations. These are stock, rooted kernels. Only super user and busy boxhave been added.
[Galaxy S II Original Android Development] aceofclubs:
Happened to me on KI8 because of no wipe. All good except had no root or cwm app. I fixed it by doing a factory reset after install.
[Galaxy S II Original Android Development] Naka_Timo:
thanks, will try it out and c how the responses.
[Galaxy S II Original Android Development] Androidin':
Another question :)

I'm rooted and used Titanium Back-Up to uninstall some of the bloatware and now for some reason 3 of them won't re-install. If I was to do an update via Odin (even though there is none available) would those apps be restored? If not what other options do I have to get those 3 apps back?
[Galaxy S II Original Android Development] MakeW00t:
Thank u. I know that it is hard to brick SGS2 but I come from Moto Milestone (euro version of Droid) and bricking MS was so much easier (according to what I read) so I just wanna be sure before doing anything.
[Galaxy S II Original Android Development] CamoGeko:
They are not re-installing probably because they were system apps that you removed. To get ethem back flash your firmware again.

[Galaxy S II Original Android Development] aqualeris:
Does the CF Root kernels come with the improved sound quality or is that only available in stock kernels for now?
[Galaxy S II Original Android Development] CamoGeko:
These are stock kernels, just with su and busybox added.

Now to work through the rooting steps!
[Galaxy S II Original Android Development] Naka_Timo:
Bro, tried your method, still cant get the CWM and superuser icon in my phone.. and the root explorer..cannot work also.
[Galaxy S II Original Android Development] aceofclubs:
Im in the same boat as you right now. Just geting back onto KI8 but for the life of me I cant get root access with chainfires KI8 kernel. Last time a factory reset through cwm fixed the issue but not this time.

tried many things but to no avail...yet..Im still on it though.

Ive flashed the stock KI8 firmware

Factory reset via cwm

fixed permisions

Ive got cwm and busybox installed but superuser is not installing correctly.

Downloaded root checker and it says...

"Root Access is not properly configured or was not granted

....

... other stuff....

...

ls:/system/bin/su:No such file or directory

Standard su binary location: ls -l /system/xbin/su:

-rwsr-s-rx 1 root root 4096 Oct 13 21:05 /system/xbin/su

...

..."

Downloaded superuser from market and same except says superuser is installed.

Gonna try a few more things to see if I can work this sh1t out. Got to be missing something simple surely.

If anyone has any suggestions feel free to bring them on.

---------- Post added at 09:40 PM ---------- Previous post was at 09:23 PM ----------

OK mate got it to install.

this is what I did.

flash intratechs KI8 firmware via odin.

when device reboots to samsung logo [edit: very important! logo is after yellow installation text has finished] use buttons to get into download mode.

flash chainfires KI8 rooted kernel.

Let it boot.

Muddle your way through to change language to english or whatever if needed.

superuser and cwm are installed correctly.

What I didnt do this time was install australian optus csc before rooting or allow the device to boot up and configure 1st time. maybe one of those was the problem.

I know sounds weird but thats how I got it rooted.

Does the CF 4.3 have the AOS bug fixed? Call me blind but i went 5 pages back and read the full first post. Sorry if i missed it.

Guys this is a STOCK kernel with root, BB and SU.

No tweaks. Nothing.

Stock plus root. That's the whole point.

good day guys, I just got my sgs2 and Im trying to root it , already read the first post about this but still unsure about it .

My device is a 2.6.35.7-I0100UMKG4-CL417954se.infra@SEI-44#2 so Im not sure wich file I need to flash , I read that if my kernel is not listed I should ask for one or just flash the closest one, but I dont know if that would be the best idea dont want to brick this expensive device hehe.

thanks for your help
[Galaxy S II Original Android Development] donalgodon:
Yes, just flash the closest match you find. You don't have to match them EXACTLY. I've found that the kernel is pretty flexible in terms of what it will support, because these are all based 100% on stock kernel (with Root, BB and SU added.)

There's no real problem with experimenting, because flashing a new kernel takes less than 1 minute. As long as you are using the 9100 Euro/International model, these kernels will be fine for you.

Just match as close as you can, and flash away. Odin via PDA while the phone is in Download mode.
[Galaxy S II Original Android Development] Valholy:
well I bought my device in mexico , the baseband says I9100UHKD8, MODEL GT-9100,COMPILATION GINGERBREAD.UMKG4 WITH 2.3.4 GINGERBREAD SYSTEM.

[Galaxy S II Original Android Development] donalgodon:

Give it a couple of days and charge cycles. It should calm down after that. It happens sometimes when flashing a new kernel.

that i found on page 1.

Jus a bit cautious because i used kies to update last week and the rootCF is dated 30th may? will it still do the job?
[Galaxy S II Original Android Development] Pfeffernuss:
No, his framework simply doesn't support a percentage-wise-battery-indication. Has nothing to do with charging cycles whatsoever.

If you flash JKay for example (if that's available for his firmware version) there will be a 100-99-98-97% battery indication.
[Galaxy S II Original Android Development] ssuukk:
Would it be possible for you to include additional modules for these kernels? I am looking for cifs.ko, I guess finding it for this particular kernel would be rather difficult...
[Galaxy S II Original Android Development] Valholy:
guys is there any chance of hard bricking your device during this procedure ?? or just semi brick it
[Galaxy S II Original Android Development] :
You'd have to do a lot of things wrong for that to happen. Follow the instructions to the letter and it's highly unlikely. In the event of something going wrong (user error probably the cause) there's an extremely high likelihood that you'll be able to recover the phone.
[Galaxy S II Original Android Development] CamoGeko:
Yes, if you are still running your regional stock rom that is.

Also you would most likely lose root.

where can i find the difference between secure and insecure kernel please...
[Galaxy S II Original Android Development] BrandoHD:
This is a modified stock kernel, just adding the necessities for root, if what you ask for is not int the stock kernel, then it won't be in CF Root Kernels....

Check which build versjon you're running (KI3 or KI8 or what ever), then flash the correct kernel that matches..

Last week, Vodafone in Croatia just sent an update for Galaxy S2 with this info :

I9100BUKI1

2.6.35.7 - I9100BUKI3F-CL604789

GINGERBREAD.BUKI3F

I can't find particular kernel that matches BUKI3F, so i should flash BUKI3 or BUKI4 kernel, right? Or am I completely wrong and have to wait for some closely related kernel?

Tnx
[Galaxy S II Original Android Development] CamoGeko:
Just look and see if you're running 2.3.5 or 2.3.4, then choose a kernel. It doesn't have to match up exactly, just the closest one will do.

Transmitted from a Galaxy far far away via XDA telepathy.
[Galaxy S II Original Android Development] CamoGeko:
That's nothing to do with the kernel, its the rom. Try flashing a different battery mod which will reduce itself in increments of 1 instead of 5.

Has anyone successfully restored a nand backup created KI8 cfrooted kernel?

I've tried heaps of things from cache wipe to factory resets, b4 and after restore, with no luck.

Looks all fine and goes through to completion but boot loops every time.

Got to be something im missing but for the life of me I can't restore any. I can restore all previously created backups just not KI8 ones.

No need to send me to boot loop thread just interested if anyone has done a successful restore.

However, last week when I was having stock cf-rooted kg2 2.3.3 hk rom, i backed up with nandroid and updated to ki3 2.3.5 hk through kies, yet, I found it used more battery than kg2 and Samsung had hold it up after a day, I decided to revert it back to kg2 until a more stable version to be out. Yet, when I nandroid restored my kg2 backup, all my apps and settings are gone, all I left is a clean rom with kg2. (I am sure I chose full restore)(I hadn't format my internal storage nor SD card)

Anyone has a clue on this?
[Galaxy S II Original Android Development] CamoGeko:

I wouldn't bother with KIES if I was you, its always has been a bit messy.

Just flash any firmware you want via ODIN. Then you can try to root again. I would suggest a factory reset as well, just to clear things up.

okay, so I've read a good amount of info so far and did some research but it's still a little confusing. I heard different ways to do things:

A

1. flash appropriate kernel

2. flash ROM

B

1. flash ROM

2. flash appropriate kernel

C

1. update firmware from Kies

2. flash appropriate kernel

At the moment I just want to get root funtionality however I want to set up the phone so that a future ROM flashing can be done swiftly without having to flash the kernel again. Regardless, I have it UNLOCKED at the moment via an unlock code from Samsung.

kernel version:

2.6.35.7 MUGKG2 -CL371789.

It is currently unlocked and used on the Rogers network.

Got it from Samsung and unlocked.

I read that I should use one of the following:

ZS_OZS_KG2

JP_XSG_KG2

As they are both 2.3.3. However I also read somewhere that someone was in the same situation as me and they flashed a stock Bell rom after but lost root? Anyway I don't plan to flash a ROM yet...not ready to have to lose all my info :(

Thanks in advance all!!! :D Hoping to get some added battery life once I find a GOOD ROM with battery mod so it shows a percentage at the top.

+1 to Chainfire and all others who have helped so far :)
[Galaxy S II Original Android Development] It_ler:
Ok, if you only want to root your phone, then do the following:

Read Chainfire's first post and root your phone!

If your current kernel is KG2, then use one of the mentioned CF-Root kernels to flash to your phone using PDA section in Odin.

As described in Chainfire's first post!

If you need a stock kernel for getting rid of the yellow triangle after rooting, you can find it e.g. in Intratech's thread (=> http://xdaforums.com/showthread.php?t=1075278) - look at the second post with Original Firmwares or alternatively at the third post with Frankenstein Firmwares.

Please remember to follow Chainfire's description!

CF-Root does NOT work, insecure kernel and root app does NOT work, pre rooted kernels do NOT work. I dont understand what im doing wrong.
