I already have CF-Root kernel and CyanogenMod 7 on my phone. I'm looking for to flash the official ICS, but should I flash a NEW stock kernel for ICS? Should I go back to my GB stock kernel before doing that? Thanks a lot, guys!

There should be instructions on whatever page you download the ICS you intend to install from... Right? Follow them.
If you will push Android 4.0.3 or other Custom ROM on your current set up, it will over write your entire OS.
Hello all,
I am a super newbee in this field ( please dont laugh ) ! I apologise if i have failed to see the solution for my queries in other threads
I own a Samsung Galaxy S2 I9100 with the following config:
Android version : 4.0.3
Baseband Version : I9100DDLPA
Kernel Version : 3.0.15-I9100XWLP7-CL340913 [email protected]#3
Build number : IML74K.XWLP7
I have already rooted the device with the help of posts on xda. I aspire to put a custom ROM of Jelly Bean in my phone. I have certain questions abt it.
1. Can someone suggest me an apt choice of ROM to suit my current build?
2. will i be able to come back to my stock firmware incase of any problem with the custom ROM. If yes, how ?
3. can i partition my ROM and have to Androids running ? Custom ICS and JellyBean ?
Please help. Thanks in advance.
JB ROMs are still in development stages and need some time to get fully baked.
If you want to try one CM is great.
And you can return back to ICS anytime.
To dual boot JB and ICS you need to flash Siyah kernel.
I would suggest you to flash (install) CM9 for few days. Bcoz its better to be using known stable build for regular use. You will get an idea of what to expect of AOSP ROMS and what are their limitations.
Then you can plunge into exciting world of flashing nightlies (less stable) builds.
You can always go back to default samsung roms if CyanogenMod roms dont suite you. There are lot of custom Samsung rom based roms to choose from with very good customizations.
But before you do any flashing of rom, BACKUP YOUR CURRENT ROM.

After Flashing Download the Custom Rom.Zip File You Want to Flash..

Hey guys.
I just bought a samsung tab 2 10.1 and want to flash it to cyanogen to get the multiple users that comes with android 4.2.x
I havent flashed in a while since i updated my i9100 to 4.1.2, so i thought best to flash my i9100 to cyanogen first to try it out as my phone is already rooted. I found a few guides for installing cyanogen to my phone using cwm recovery to install from the SD card.
I remember rooting my device back when i updated it to 4.1.2 but when i tried to boot into cwm is would boot into the stock android recovery.
so i figured i needed to flash cwm recovery.
after checking all kies processes were stopped i flashed the kernel "GT-I9100_ClockworkMod-Recovery_4.0.1.4" , but the phone would not boot and hang at start screen.. as a plus side i now had access to cwm recovery from boot... ironic.
so i booted into cwm recovery thinking to install cyanogen mod as i thought maybe the rom wasn't compatible with the kernel?
but noticed that the cyanogen rom was not present on the menu in cwm recovery, must of put it in the wrong place. I was now thinking to get my phone to boot into 4.1.2 that should still be on the phone, since the current kernel wasn't working i flashed "Siyah-v5-MCM-i9100-vsync_sysfs-20130217" in hopes it would be compatible.. still no luck with it booting. but i still have access to CWM recovery.
Any thoughts on how i should proceed? if i can get cyanogen onto the SD card should i install it via CWM?
little lost at the moment. been a while since i done all this.
here is the information i noted down before i started today.
4.1.2
i9100xxls8
3.0.31-863787 [email protected] #3 smp preempt thu jan 31 12:20:07 kst 2013

Thanks for reading.

Philz kernel lss flash that through odin. Reboot to recovery, do the wipes and and reboot. 4.1.2 should boot up then. Then move custom rom to int sd and flash away. Philz installs custom cwm. Once you have flash custom rom philz will be replaced with stock custom kernel with cwm built in to it.

I'll give it a shot, is the Philz kernel you mentioned this one?;
<< 03.06.2013 - PhilZ-cwm6 v5.06.1 with CWM 6.0.3.2 based recovery >>
I'm not to sure what kernel version i need.
how would i find out this information ?
Many thanks.
Edit:
I noticed in my previous notes i made when first flashing my phone a year or so ago. The kernel i used was this;
3.0.15-I9100BGLP8-CL317471 [email protected]#3
It is now kernel version;
3.0.31-863787 [email protected] #3 smp preempt thu jan 31 12:20:07 kst 2013
which has no reference to previous kernels. but my current baseband version is: i9100xxls8
LS8 stands out in both... so would using PhilZ-cwm6-XWLSY-ORA-5.10.0.tar.md5 work on my phone?
Lss will work as it for 4.1.2 it just has newer cwm installed.tar is for odin. You could get the zip one and put on an sd card put bk in your phone and flash it like that. Make sure its zip not tar for flashing in cwm.
Thanks

Thanks, that worked. opted for no installing the nightly version of cyanogenmod as i would like something more stable on my phone.
I've been looking at Resurrection Remix 3.1.2 or CM1UI Jelly Bean.
Is the Philz kernel i installed a widely compatible kernel or should i install Siyah ? my last attempt to install Siyah kernel lead me to write this post.. how would i go about installing a more widely compatible kernal with out ending up in a hang screen again ?

By 'compatible', you mean the kernel works with many ROMs?
Philz is a stock based kernel. So it only works on stock based ROMs, and depends on the android version and the build versions (like LSS, LSJ, LSD etc). Siyah is more compatible, because it only depends on the android version (like JB, ICS or GB).
You had a bootloop before after flashing Siyah mcm kernel, because the mcm kernel supports AOSP 4.2.2 ROMs, not stock JB.

To avoid bootloops after flashing a kernel, use these tips:
1. Flash only kernels supported by your current firmware. Suppose you are running stock JB and you want to flash AOSP 4.2.2 ROM. You might be tempted to flash Siyah mcm kernel (because it supports AOSP 4.2.2). But that would end up in a bootloop as Siyah mcm doesn't support stock JB! :good:
2. Use a kernel cleaning script before flashing any kernels. :good:

Thanks for your reply, i have a few questions to try and understand.
Would i be right in saying;
When im looking to install a new kernel and/or Rom. My check list should be;
1. Kernel to phone compatability. I.e my phone is LS8 so i look for LSS/LSY/LSD soforth and so-on.
2. Kernel to Romcompatability. I.e Philz is a stock kernal hence why it works with 4.1.2 stock Rom.
So if i want to install Resurection Remixed i believe its a modified stock Rom so it should work with Philz?
As would cyanogenmod as it is modified stock?
Or is even that modified to much?
If i want to change both kernel and Rom, would it work if i installed for example siyah kernel then boot into CWM recovery and installed from there a new Rom?
Im looking to try out a few roms on my i9100, mainly Reserection remix, and other cyanogenmod clones with light modification as i enjoy the stock android experiance.
Also looking to install cyanogenmod to my p5100 tab. Flashing Philz p5100 kernal and then installing superuser through recovery and then installing cyanogenmod 10 stable version?
thanks for reading and taking the time to anwser my previous questions.
Many thanks

Don't worry, things can be a bit hard to digest at first.
Let me make it easier:
1. U are currently using a stock or custom ROM, but you want to change the kernel (without any plans to flash a new ROM). In this case, you need to select a kernel that is compatible with your current ROM.
2. U are on a stock ROM, and you need to flash a custom ROM. You want to flash a kernel to root it and install CWM (to enable u to flash a new ROM). In this case also, u should flash a kernel that supports your current stock ROM.
3. U are on a custom ROM, and you want to try another custom ROM (which may require another kernel to support it). In this case, you DON'T need to flash a new kernel that will support ur new ROM. You can flash the new ROM directly. All custom ROMs come with their own supported kernels bundled in the ROM. So, after flashing the new ROM, your current kernel will be REPLACED by a supported one from the new ROM.
Better?

So my breakdown would be I'm using a Stock ROM with Philz kernel rooted and CWM. I want to Install Resurrection Remix which is a 4.2.x ROM, Philz is a 4.1.x Kernel so i need to install a new kernel to support Resurrection Remix? or would that come with its own Kernel?
And for my tablet. I flash Philz kernel and install superuser to root the device. so now its stock Rom with Philz kernel. So when i install Cyanogenmod Rom it will install its own Kernel or do i also need to install a Kernel that supports 4.2.x?
Or is it Firmware version based Kernel updates that happen when you install and new custom ROM?
i.e Running 4.1.x kernel and installing a 4.1.x Custom ROM will update the kernel, but installing a 4.2.x ROM will not?
vice versa Running a 4.2.x kernel and installing a 4.2.x ROM will update the kernel, but installing a 4.1.x ROM will not?
Kind Regards, I appreciate your time for reading my mind numbing questions.

For you i9100 just flash the rom using philz cmw recovery and once its done you will have a custom rom with custom cm kernel which is rooted and has cwm with it. I would say to format system ,data, cache and preload before you flash it using philz recovery and make sure the rom and gapps is on int sd card were you can find it.
As for the tablet make sure philz is compatible with that tablet first!! Dont just flash it on that thinking because its 4.1.2 it will work.
Btw with philz also come with root access too.

No, you don't need to install a new kernel, because flashing RR will flash a compatible kernel (included in the ROM) by itself. :good:

Don't overcomplicate stuff mate. When you flash a ROM, the kernel contained in the ROM will be replace your current kernel. Simple.
Thanks a lot!!!
I installed RR to my i9100 and cm10.1 to my p5100.
I'm having a little trouble with i9100 device though, I keep getting random sim locks on the device.. Not sure what could be causing it. It didn't happen on stock 4.1.2.
The devices will be locked and when I wake it I get prompted for the sim lock code. I now have the sim lock on my phone deactivated but I'm fearful that even thought I am not getting prompted for the sim code, the sim could be de-activated while the phone is in sleep thus not connect to the network?
Could be a loss of signal activate a security feature of the sim. Or a problem with the kernel?
Kind regards.
Many many thanks for all your advice into helping me understand a little better.

If you're sim locked, then you want the app 'Galaxsim unlock'. Search for the xda thread, the OP is spocky12 if that helps you find it. It won't be kernel related. And, test it for yourself. See if you get messages /calls / push notifications while your screen is off & phone is sleeping.

The i9100 was originally sim locked, but I paid someone to unlock it, once I got the phone back from him "unlocking" it. It was apparent that he has flashed the device with a new kernel and ROM in order to unlock it... Not to sure of the process. A couple months later I flashed 4.1.2 as it wasn't available as a update on the ROM he installed. The phone re-sim locked and I downloaded the app you mentioned and unlocked the phone successfully, been happily using it up until I installed RR. Now I'm suffering from random pin locks. The phone connects to the network and functions perfectly, apart from said sim locks.
My only fear is missing important calls if this lock is causing network disconnections. Can I log network functions and connectivity to see what's causing it?

Hello and Good Day Devs !
I am kind of a newbie in the world of rooting (for samsung galaxy s2 gt i9100). So i just recently got my dad's permission to root and flash a custom rom on my device . I am currently using a samsung galaxy s2 gt-i9100 running jelly bean 4.1.2 XWLST . Am from India and i am highly confused. So i would like to know which kernel would be the best for rooting my phone (best i.e. safe , bugless) After rooting i am planning to flash a custom rom. I would Most probably flash the PACman ROm (jelly bean 4.2.2) and would like to know which kernel would suit the rom. rather i would like to know which kernel is supported by the PACman rom. i searched and read a few threads and concluded that siyah is a bit buggy causing a lot of problems . Philz is a good kernel but i also read that PhilZ's kernel is not supported by a few roms. I also checked out the 'jeboo" kernel and found out that it was somehow related to the PHilZ kernel and eventually backed out . So pease help me out devs .. any help would be appreciated and thanks a lot for your co-operation :laugh:
Whatever kernel you flash will be overwritten when you flash your custom rom.......every custom rom comes with its own kernel......
So the choice is yours......
Select your kernel and flash it however the instructions say, then flash your custom rom.....job done.....no issues/worries about incompatiability........

start with siyah kernel v6.0b5
It is the safest kernel to start with
Then flash pacman
It is your choice to flash a new kernel over the stock pacman kernel
You can flash whatever custom kernel you like and as @keithross39 mentioned dont worry about incompatibility
Use odin
Gud luck mate
The only time you have to think about kernel compatiability is if you decide to flash a kernel on top of your custom rom. As I previously mentioned, the kernel you flash to root your phone will be overwritten when you flash the rom, so no incompatiability will exist because you will have basically erased that kernel during the flash. But any kernel you flash on top of your new rom HAS to be compatiable or you'll end up with an unuseable phone......

Hi guys
I have the following isue, i flashed my phone and I used this kernel
3.0.31 siyah s2-v6.0b5+ [email protected] #177
Now I cant make calls, I can't hear the person who call me and that person can't hear me, the phone radio doesn't work, sometimes the phone freeze specially when I watching videos. The phone doesn't recognize all internal memory. The return and search button doesn't work, to go back now I have to press the home button.
My question is: can I flash the kernel i have installed and install a new one. What kernel do you recommend me for this phone that works fine and what rom 4.2 is the best for this model.
I really appreciate any help.

Your signature says your phone is GT-I9100, but this is the forum for SGH-I777 AT&T version of Galaxy SII. Which phone do you have?
I have an i777 from at&t, after i flashed the kernel the phone model changed from i777 to I9100, but it is an i777 from at&t

Did you flash only the kernel, or did you also flash a rom?
What version of the operating system, and what rom are you currently running?
The kernel you flashed was built for the GT-I9100, which has a different hardware configuration from the SGH-I777. You should flash a kernel that was built for the I777, probably AJK, but answer the above questions first before I suggest which one.
First I flashed the kernel and installed the siyah one, then I installed a different rom. I had before 3.2 and then I installed 4.1.2 rom. Can you recommend me a god kernel for the I777 and a good rom if it possible 4.1.2 or 4.2 . I really appreciate your help.

You appear to have flashed the GT-I9100 stock XWLS8 full package. Most likely you flashed the I9100 boot loaders with it. You also have an I9100 modem. I'm guessing that you flashed the I9100 siyah kernel afterwards. Your I-777 will not function with that firmware. I am surprised it even booted into system.
First, double verify that you are working with a SGH-I777 by pulling the battery and looking at the label in the battery compartment. After verifying that you have an I-777, you should flash the AT&T version of stock 4.1.2, I777UCMD8 full package which you can get from the download repository.
If you are unsure of anything, or have any questions, please ask before proceeding.
If you want to root and install a custom kernel, or install a custom rom, after getting your phone working again, we can point you in the right direction.
Thanks for your help, yes I verified and it is an i777 from at&t.
A have some questions:
1- I need to flash the kernel first and then install the new one?
2-can I install a 4.2 rom with the kernel you recommend me? I really like to have 4.2 on my phone.
3-how I get rooted after do that?

No. Flash the I777UCMD8 full package from the download repository first. It contains the complete firmware, including stock kernel, stock system, an AT&T modem, and the I777 boot loaders. You can do any modifications after you return the phone to full stock 4.1.2.

I am answering this question next, because it is the next step after flashing the stock firmware. To root, you should use the Framaroot application which you install on your phone. Use the Aragorn exploit. If the latest version doesn't work, download and use an earlier version, like 1.4.2.
2-can I install a 4.2 rom with the kernel you recommend me? I really like to have 4.2 on my phone.

Once rooted, you should use Mobile Odin lite or Mobile Odin Pro to install a custom kernel containing ClockworkMod Recovery. With this stock firmware, you would use AJK v4.9 No Swap.
After downloading the kernel, open the zip file and extract the boot.img. Use that to flash in Mobile Odin. After flashing the capacitive buttons will not work, so immediately reboot into recovery and flash the full AJK v4.9 No Swap package in CWM.
4.1.2 is the latest version of stock firmware available for the I777. If you want the Samsung Touchwiz interface, that is the latest you can get. Anything available 4.2 and above will be AOSP based. You can look in the I777 Android Development forum and the I777 Ported Development forum to see what is available. They all flash from ClockworkMod Recovery.
Ok man thanks, I'll do that, after that I'll let you know how everything goes
