Root & Rom a stock EU Galaxy S2 ICS - Galaxy S II Q&A, Help & Troubleshooting

Hello xda forum,
I'm a total newbie to rooting and flashing Android and I would like to root and install a custom rom based on Jelly Bean.
That would be the AllianceROM i9100 JB V5.2.
Is there a overclocking tool included?
My Phone is a Galaxy S2 european version with stock Android ICS.
Is there a way to root the Galaxy on a Mac, or is a PC with Odin required?
Is it enough to just root the phone and then install the file of the AllianceROM i9100 JB V5.2?
What method is the best to root the Galaxy S2 ( I don't mind losing the data on my phone, backup already done )?
Do I need a kernel or modem or is that all included?
Thank you for the help.
And sorry for the total noob questions...

yes, in sdtweaks that come with rom, there is a section that will allow you to overclock.
My Phone is a Galaxy S2 european version with stock Android ICS.

You can use heimdall on a mac to flash but it is safer and easier to use a computer with odin as there have been some reported problems with using heimdall.

Once rooted, just follow the instructions posted in the AllianceRom thread as recommend by the developer.
What method is the best to root the Galaxy S2 ( I don't mind losing the data on my phone, backup already done )?
easiest way is to flash the siyah kernal with odin and it will root your phone.
here is the link to the siyah 4.1.5 kernal.
DOWNLOAD TAR (for Odin)
Do I need a kernel or modem or is that all included?
once rooted, kernal, modem and all other files are included in the alliance rom that you want to install.
Thank you for the help.

Before yu start flashing read and understand the flashing instructions throughly to save yourself from mistakes caused by improper flashing.

Thank you for the reply!
I thought that the root method with flashing a siyah kernel was not possible since in the AllianceROM 5.2 thread the following is mentioned:
" Kernel - Philz safe kernel. THERE IS NO SIYAH OR DORI FOR SAMMY JB. DONT ASK FOR IT!!! "
So people who want to install the Alliance ROM on their stock Android 4.0.4 Galaxy S2 should just root their phone and then use the ROM Customizer to install the zip file from the internal sd volume.
Or flash the AllianceROM ICS version with Odin and then use ROM Customizer to install the AllianceROM 5.2 package.
( Which has the Dorimanx Kernel I've heard? )
Ok.
Thanks for the help again.

No odin it is a flash tool to flash entire rom or kernel.
Kernel are normally rooted so you can flash a tar file in pda and obtain root and cmw to flash custom rom.
To flash you have to put phone in download mode.
Custom rom have different graphics and some feature but battery life is same.
I suggest you cf root kernel to root and gain cmw.
Also to know your firmware version dial *#1234* and check pda

Please read the Quick Root Guide in Intratech's first post of this thread => http://forum.xda-developers.com/showthread.php?t=1075278
He describes two rooting method, but as you are running a relatively new ROM, the zergRush exploit method won't work for your phone. (The other rooting method will work fine.)
The easiest rooting method is to flash a rooted kernel, such as CF-Root.
Here is Chainfire's thread => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root
Stick to his description.
There are a lot of other "good" kernels which will root your phone, increase performance and extend battery life (e.g. SpeedMod, Siyah, NEAK and RedPill).
You will have to search a little bit and then make your own decision.
P.S.: After flashing an insecure/custom kernel, you will get a yellow triangle at boot and the binary counter will be increased.
That's why Intratech and Chainfire also describe how to get rid of the yellow triangle. Or you buy a USB Jig to remove the yellow triangle and reset the counter.

[Q] Galaxy SII Upgrade with Siyah Kernel And Ressurection Remix Kernel

Hello I Bought a SGSII With Andoid GB 2.3.4 I Want To Install This Fw:http://forum.xda-developers.com/showthread.php?t=1436854 and this kernel:http://forum.xda-developers.com/showthread.php?t=1555259
How to do please?I must Update to ICS Or not? and did Siyah Kernel replace CMW(I was on Galaxy Mini)
Help me please
The answers to your questions are in the threads you linked to, I.E follow whatever specific instructions the rom/kernel you want to flash has.
Siyah has it's own version of CWM & this will overwrite the current version you're using (that's if you're using a kernel that has CWM before you flash Siyah, obviously).
Read those two threads very carefully, all the info you need is there.

If you know how to flash kernels via odin its simple. Just download siyah kernel for i9100 , install the drivers required fr odin , flash the kernel in download mode. It will give you rot access and CWM recovery. Then yo can boot into recovery,wipe data/cache and install any rom you want. But do not wipe anything n stock recovery since you are on 4.0.4 (which has the brick bug)
you can also root by stock recovery just by flashing a single .zip file. But if you know the way to do it by odin i suggest the odin mehtod.
and to flash JB....MobileOdin Pro.......so you'll forget about rooting with the EverRoot option........................beware of the wipes with 4.0.4 tho, that crap is nasty.

[Q] clear some things regarding kernels , roms on new ics 4.01

hi,
i have a new sg2 i9100 version witch came with 4.04 and no brick bug as reported the emmc.
i am searching for days and i am a bit confused .i am not familiar with that kind of softwares and i would like your help.
the goals: i want to root, and to be able to flash any rom i want.
1)if i understand so far i will need a kernel too?
2)i do not have the knowledge to understand what varius kernels offer and i simply choosed the siyah since it is the most popular(??) the s6 version states "This kernel is only for Samsung JB ROM (No ICS support anymore).
that means that my ics 4.04 will not be accesible and working anymore and i should flash a rom imidiately after the kernel flash?i do not mind to flash rom imediately after siyah kernel since i do not have anything instaled on the phone yet.
is it posible?with odin?1.86 , 3.04?
3)after the siyah kernel flash from the oficial siyah site , do i have root?
4)do i have cwm? if not what do i need to do?
5) is the siyah consider safe kernel?
thanks
i apreciate your help.

Frist root your phone, everything will be explained in the thread. Check FAQ
If you don't know what you are doing, don't flash siyah and stay with the kernel that gets installed when flashing the rom you want.
Flash a custom kernel with Odin. Another Siyah kernel than v6 will do, just check the changelog.
You will have root, CWM and you're able to flash custom roms. You can choose to try other kernels than the one that comes with a rom, but it's not a must.
And the person above is right: If you don't fully understand all this, try to learn a little bit more. It will prevent you from doing something wrong.
Good luck.

S2 I9100P Help please

Hello, and many thanks for your great efforts here. I have purchased a new i9100p mobile. Now, i want to root then try a new ROM. My kernel is 3.0.15-i9100pxxlps-cl674609, so i have downloaded a root file '' CF-Root-SGS2_XX_OXA_LPS-v5.4-CWM5'' is this right?
second thing, after making it with odin, do i have to install superuser? or just root with the above file and i am rooted? and later i can install any ROM.
last question, now i am on 4.03 originall stock firmware, and i want to try custom Rom 4.4.1, is it possible after rooting?
help me please, i am a noob
The CF Root method is meant for the I9100. But since I9100P is almost identical to the I9100 (except for NFC), that file should work. However, I suggest you go for Philz kernels, which includes root kernels meant for the I9100P also.
After flashing CF Root or Philz kernels via Odin, you don't need to install Superuser app. It will be installed automatically. And yes, you can try any custom ROM after rooting, including 4.4.1.
