Hey XDA !
I've just installed the 4.0.4 ROM from Free (French operator), and I'd like to root it. I tried to with the non-PC solution, but it failed (no service). I learned that I had luck that my phone didn't brick. So, I'd like to know how to root it, and install CM10 on it (I tried to install CM10 too, but I had a keyboard issue on every ROM, and I don't think it came from the ROM itself).
So, how do I do it ?
Thanks
iSteelZ
flash siyah 4.1.5 kernal to give you dual boot cqapability then follow instructions in the cm 10.
there are numerious threads on dual booting in this forum.
Do I have to keep dual boot ? Can't I just have CM10 ?

Yes.
Just flash the kernel then factory wipe and install your rom via recovery.
This is same process as any other flash, these "how do I flash" threads are silly and have no purpose as they already exist in abundance if you would look and read stickies/guides etc.
I know it must be very boring to always see posts like mine, but I already bricked my phone, I don't know how, and I don't find any topic on how to install it, only on Galaxy Note.
And my version is the LQ2, not the LQ6 (this is my modem).

Not only boring, but it's against the rules, because if you search a bit better there actually are guides for rooting, also via google if you can't find them on xda.

You are right, I looked on google for Siyah Kernel and I found the right one.
Sorry

hi, sorry for the noobish questions. :L
i have a couple of questions, i have heard about checkrom but i havent been able to really find out what it is, could someone please tell me ?
my other question is would i be able to flash miui on my phone?
my phone's details are:
model number: GT-I9100P
Android version: 2.3.4
baseband version: I9100PBVKI2

build number: GINGERBREAD.BVKI3
it's the nfc model locked on orange uk.
thanks
You need a P rom to flash as far as we know so far .If you flash a wrong firmware you can brick your phone .
Checkrom is a custom rom if you go to the Checkrom post in the developers thread it wil giver you a descriptions . Same goes for all custom roms page one this rom is and has the following or not .

does this mean i cant flash miui ?
You can only flash a P rom unless you find evidence to the contrary . Most roms are for i9100 version .
Or be a guinea pig and try .

You can flash 9100 ROM on your 9100P
But 9100 ROMs don't support NFC module (it will be supported natively with ICS).
I have the same device (orange FR) and you can look my signature for working Radio + ROM...

I dont remember
But if your device is already rooted you can install Rom manager or CWM from the market and make a backup of your config. Then reboot in CWM and install what you want (read the how to install section of the wanted rom).
Don't care about your "P" version!
What you read here for standard device (i9100) is working for your P version.

Don't use Rom Manager, use Clockwork. Rom Manager seems to not work well with the SGS2, this forum is littered with posts from people who used Rom Manager to flash and it broke CW Recovery, put the phone into a bootloop or soft brick, etc, etc.
Best to play it safe IMHO.

Oh I didn't know that rom manager was not working fine on our device. I am using clockwork manager and it is working fine.
I've seen a heap of posts in the couple of months I've been visiting this forum from people who ended up with broken CW Recovery & bootloops after using the Manager app.
I used it once to try and flash a kernel & it broke recovery completely.
Obviously any/everyone's mileage may vary, but for me, I'd rather play safe & boot into Recovery whenever I flash or backup.

so if i shouldn't use rom manager, what should i use ?
Didn't say you shouldn't use it Just said that plenty of people have had problems using the app, and rather than risk it, since I had that problem with it, every time I've done a backup or flashed a rom/kernel I've rebooted into recovery & used CW Recovery itself to do the business
As I said in my previous post, your mileage may vary & you may not have any problems with it at all.

Hello guys! I have a GT-I9100P also with the latest BVKL2 2.3.6 firmware. I had it rooted when I was at BVKI3 2.3.4 firmware and now I am looking for a good CF-ROOT kernel for my phone. What would you recommend me? (what if I tell Chainfire to make a CF-ROOT more appropriate to my kernel)?

Why don't you post in Chainfire's thread to ask him about making an insecure KL2 kernel?
But I think you can use the insecure KL1 kernel from Chainfire's thread to use for root. Or you could flash SpeedMod or Siyah, and the rooting will happen for you. You have lots of options.
were to put the rom zip file
I got the exact same phone as the OP im trying to flash a rom in a zip format but clockwork mod recovery cant find the file ive looked in install from sd card and install update.zip. ive also tried installing it through rom manager, no joy there, inside rom manager i chose to boot into recovery to flash it manually and now i got a black screen with a white triangle n a lil green android dude so i see what people are saying about the s2 and rom manager, anyways my question is were do i place the zipped rom? on the internal or external and should i rename the rom file?
Ive had 2yrs experience with a HTC HD2 so im not exactly a noob to flashing roms, but the galaxy s2 is very new to me.
hi guys,
i'm new here so i don't know how everything works,so i could use some help.. i've recently rooted my phone using CF-ROOT 5.0 XWKJ1 and i'm a bit confused what to do now.. i wan't my phone to run on newest stock firmware, which one should I use ? the most recent one in intratech thread is XWLA4 (phone is XXKI4,just like mine,so it is for my phone or what does it mean? ), can I just flash it to the phone ? can i do it through CWManager app ? and i still don't entirely understand the difference between Kernel and ROM, I'd also like to try the cyanogen mod,what should I do first ? and how can I flash back original stock rom ? because cyanogen is 100mb and original rom is 8, so I'm not sure if it will restore the phone to the stock state after flashing stock rom back.. and yes, I've read the guide to GalaxyS2 and Android,but still do not understand everything..
thank you guys for your effort.

You need to start reading the guides your questions are all answered in the relevant guides .
You want CM you follow the instructions for CM you want xxx you follow the instructions .
ROM is firmware kernel is part of the firmware that interfaces OS and Hardware .
But suggestion is to wait for release of ICS .

Take time out to read the guides as it'll help you out.
XDA is a development forum and requires leg work!

No. Those would be for the GT-I9100 I believe. The kernels for the I777 will all be available in this forum, in the development section. You must use a Gingerbread kernel with a Gingerbread system, so when you are rooting with UCKH7, the two main custom kernels are linked in the guide. That would be Siyah, and Entropy512's daily driver. Either one will work fine to get you ClockworkMod Recovery. You'll probably be flashing a different kernel when you put on a new firmware anyway.

Use the Siyah kernel from here:
http://forum.xda-developers.com/showthread.php?t=1592228
It is the same kernel from the website you found, but adapted specifically for the I-777. There are two versions. For aberration i believe you need to install the version WITH micswap, but check the threads to make sure. If you are using it with another ROM, check the first post from the thread above, they list which versions you need for different roms.
One caution: some people have reported problems when installing v4 of the kernel immediately after flashing a new ROM. To avoid problems, Flash your rom, reboot the phone fully, then go back into CWM recovery and flash your kernel. Or, if you are not flashing a jellybean rom, you can just use version 3 of ktoonsez kernel instead of the version 4 beta, and avoid the problem altogether.
Edit: oops...seems creepy beat me to it. Just do whatever he said, he is one of the most knowledgeable people here

@bigote,
Maybe I misinterpreted your question, and wgoldfarb has it right, but just to be clear...
If you are rooting the phone with UCKH7 plus root from my guide, you will need to install a Gingerbread custom kernel to get ClockworkMod Recovery so that you can flash Aberration. In that case, DO NOT use this kernel since it is for ICS and will not boot when flashed with a UCKH7 system. Read and follow my previous post.
Once you have Aberration installed, then you can upgrade the kernel to the latest Siyah ICS kernel from this link.

Sorry, when i replied i had not yet seen creepy's post. As i said above, just follow what he said.

In any case, if you are ever in doubt, you can never go wrong with creepy's answers.

You are right, go for SiyahKernel (latest) (safe -> no mmc) Flash it with Odin.
That will give you a safe kernel with Root then you can follow instruction in CM website (CM10 zip + gapps) to get a working CM10.
Search XDA for more help. There are lots of articles on this!
Same prob here..

Hi
this is my first post here and im new into Android world, not even a month with my S3, have a bit of patience, sorry if im going to make such obvious questions that sound a bit "stupid" to experienced users, but i need to know exactly what to do, and i have to understand
first of all i like reading, i already took a look at about twenty different ROMs/ and read about Root.
i think you'll need my device infos:
