Might be worth mentioning that for those of you who have updated to ICS via Kies and now wish to root your phones, this guide still applies.

hi i have done everything, Step 1.

Ensure that your phone is fully charged.

On your phone, go to... Settings > Applications > Developement > USB debugging and check the box.

Put your phone into Download mode by turning it off completely and then press and hold the following buttons... Volume Down + Home (centre hard key) + (lastly) Power. Continue to hold these buttons until your phone boots into the Warning! screen asking you to press volume up if you want to continue or volume down to cancel. Press volume up.

Step 2.

Right click on Odin3 v1.85 and select, "Run as Administrator", to open it.

With Odin3 v1.85 displayed on your PC screen, click on the PDA button and navigate to the CF-Root Tar .zip file, that you placed on your home screen, and select it.

Make sure that Re-Partion is unchecked and that Auto Reboot, F.Reset Time and PDA are checked and that the PDA box now contains your .tar file.

Step 3.

Connect your phone, still in Download mode, to the PC using the USB lead. If you have successfully connected to Odin3 v1.85 you should see the ID:COM box in Odin turn yellow.


now the box does not go yellow what is going on i download the CF-Root-SGS2_XW_XEN_KK2-v5.0-CWM5.tar, I have a i9100xwkk2 so i guess this is right? please help my phone has not been nice to me since i started to back it up.
really want it rooted so i can remove all the crap optus put on it that i can not remove now, also want better battery life.
why is it not going yellow???

thanks in advance

Did you complete this step in post #1 and did it connect to Kies?

You're not the first to do that, (or not do that as the case may be).

Congratulations on rooting cybaree!

Before rushing into anything, please read the rest of post #2 and make a Titanium and nandroid backup.

You don't have to put a custom ROM on to get rid of bloatware, as mentioned in post #2 but if you really want one, may I suggest CheckROM RevoHD v6. A Gingerbread ROM that is very stable and popular. I'm not recommending an ICS ROM as, IMHO, they are not without their problems still and probably not a good choice for a first time flasher.

Hi Cybaree, don't feel silly, I did exactly the same. But the guide is exellent and I agree with the CheckROM RevoHDv6, works like a champ

Hi khun wim!

Yes, I remember now, you did do the same and I posted this afterwards:-

Default Amazing...

Ironass, you are a goddamn hero! Not being the least bit sarcastic. Yours is the guide I used which both: 1) best explained terms I was (and still kind of am) unfamiliar with, and 2) best described the rooting process and post-rooting tips.

Thank you so very, very much, and thanks also to all the posters, senior members, mods, etc. for asking pertinent questions and elucidating the mysteries of everything Android. It's completely beyond me how some people can teach/discover for themselves so much about complex technology--from mobile phones to computers to cars to anything that's not a pulley or lever--and are always willing to help others out.

Again, many thanks!

Congratulations on rooting your phone FiveBodyBlade!

WOW!

What can I say?

I'd like to take the credit for the, "Dummies Guide", but there are those on this forum who know, only too well, that I am as thick as two short planks!

It's really an amalgam of lots of different posts, from all over the web, that I tried to bring together to form as safe a method of rooting the SGSII, for absolute beginners, that I could possibly write.

Before posting the original draft I had to run it by other, more experienced forum members, such as Slug, Hawker and Shotgun84... who were only too keen to point out the errors in it!!!

Thanks to their, and others, help, we arrived at a "Dummies Guide", that didn't actually brick your phone.

Since publishing it, I've updated it constantly to keep abreast of events and to take into account things that people were finding difficult about it. For instance, one young lady PM'd me and said that she did not know how to extract a .zip file. Something I hadn't thought of.

So, what you see now is a culmination of effort and, hopefully a guide that people can refer to, at their leisure, that not only roots your phone but also gives you some ideas as what you can do with it afterwards.

So, on behalf of everybody concerned, thank you very much for your post and good luck with your rooted Galaxy SII.

I have to say, I read post #1 and #2 and you've laid out the Rooting procedure clearly and succinctly. For that you have my thanks.

A couple of questions though if I may as i'm about to root my phone and i'm a bit nervous (actually, very nervous).

I'm running an SGS2 with ICS 4.0.3 and XWLP7 kernel. I've got the latest version of Odin and Kies is up and running fine and the phone connects perfectly.

I've downloaded CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5, which I believe to be a close-to-stock rooted kernel and compatible with my phone as it currently stands and I have a USB Jig ready to go too.

I have a couple of questions and I know the answers are on here but I just do not want to brick a brand new phone by being an idiot, so i'd like to ask them plain and simply just so i don't screw up, if I may please?

If a new version of ICS is released, say 4.0.4 and/or beyond, can I use Kies to update my phone please? All the signs i've read seem to say no and that I would have to use another program called CWM (Which I think stands for ClockWork Mod). How difficult is this procedure please? It looks like CWM is here - https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager&feature=sea rch_result#?t=W251bGwsMSwxLDEsImNvbS5rb3VzaGlrZHV0 dGEucm9tbWFuYWdlciJd


Whilst rooting looks to be very easy, providing I follow all the steps carefully as laid out in the initial posts, flashing a new ROM looks to be a potential ballache though. As does using CWM to update the firmware if a new version of ICS is released for my carrier/phone.

If I wanted to return it to stock, I guess I would flash the XWLP7 from here - http://forum.xda-developers.com/showthread.php?t=1075278 pretty much using exactly the same method used to root it. Is that right please?

Sorry for being a noob. Be gentle!

If you root, your phone will no longer be recognised by kies so if you want to update your phone to another official firmware you will need to use Odin again. You just download the file and flash it the same way as the cfroot kernel you use to root.

It is custom roms which you instal using cwm. There is a good guide to flashing checkrom here
CheckROM v6 - A Dummies Guide to installation

This can be applied to almost all roms as the method is the same.

I wouldn't recommend using that app from google play as ROM manager doesn't play very nicely with the gs2. Cwm will be installed automatically when you root with the cfroot kernel, which is the right one by the way.

It worked without a hitch. Rooted now!

The USB jig put the phone in download mode but it won't get rid of the warning triangle unfortunately. Even after following the video tutorial carefully it's still showing the triangle. Shame, as I wanted it gone.

EDIT: Damn, I just found out that USB jigs don't work on ICS. Apart from using Triangleaway app, is there a USB jig that works on ICS please?

The jig doesn't work with the new bootloader so all you need to do its flash the old one using Odin then the jig will work. It can be downloaded from here

Its in the middle of post #2 under the DXKH2 firmware.

I'm not too sure if the ota option will work as you are rooted. If it does work it won't brick your phone but you will lose root. Random reboots are usually caused by your firmware. On some of the older firmwares I had the problem quite frequently but the problem disappeared for me with the 2.3.6 updates.

If you are considering flashing ICS to your gingerbread, rooted phone, I would recommend a full wipe of both phone and Internal storage, prior to flashing ICS. After the boot into ICS you will then be able to sign in to your Google account and re-download Titanium Backup Pro.

Of course before commencing such actions, you should make both a nandroid and Titanium Backup that are saved to your external SD card.

Please help guys. I think I killed my S2

It's a the GT-i9100P through o2.

VERSION

PDA i9100PXXLPH
PHONE iI9100PXXLPC
(Need the rest?)

I rooted as per the instructions given in the original post, Using CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5

The root all appeared to go successfully. The phone went to reboot and brought up the i1900 Logo with the warning logo beneath. But after that the screen is just black, no sounds or anything.

I tried once again via odin, Pass again. But still the same problem.

Oh what have I done Please please help!

Hello and welcome to Android Forums TaKeNUK!

Just to clarify...

You have a Samsung Galaxy S2 GT-i9100P variant with NFC on the UK O2 network but with Mobitel, (Slovenia) carrier branded firmware installed on it, which I guess you flashed with Odin?

Have you got the original, full, kernel version that came with the above?

Hello Ironass! Thankyou for your welcome and reply

I do indeed have the o2 Branded Galaxy S2 NFC (i9100P)

The firmware installed was updated last week via Samsung Kies.

Very confusing to see that it's actually another carriers firmware?

I do not have the original full kernal unfortunately. I didn't know how to back this up, or if it was indeed possible. So I just rooted the phone with CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5

After three more attempts with the same LPH Kernal this morning I tried using CF-Root-SGS2_XW_O2U_LP3-v5.4-CWM5 which seems to work ok!

The parts o2u and LP3 seemed similar to the CSC i9100Po2ULP4 which is listed in my phones version.

Have I done the correct thing? Many thanks.

I have replied to your PM's but, in short, it would appear that your phone, purchased through eBay, came with Mobitel, carrier branded firmware which is why you could update via Kies last week, since O2 has not released their ICS firmware for the P variant yet. Glad you have it rooted now!

Congratulations!

Somehow i've messed up my attempt at rooting.

I have an Orange phone I9100P with the latest ICS update done using Kies.

CF-Root-SGS2_XX_OXX_LP6-v5.2-CWM5.zip was the kernel i used, and now sadly it just doesn't reboot but stays at the Galaxy S2 screen.

Everything seemed ok in ODIN but it did not reboot, although i can get into ClockworkMOD.

-

As far as i can tell i did follow the instructions given, and i know they are easier but i update my ZTE Blade a fair bit and have encountered the odd bootloop, but with this i am stuck sadly.

Any help would be appreciated, i did read the guides and it all seemed to flash alright.

I'm not familiar with the, "P", variant, so could you give me the details of the original stock kernel that was in ICS firmware, prior to you flashing.

Damn, i noted that down on my works machine.

Essentially the firmware ended on the same LP6 characters that the CF kernel i chose did.

Try wiping your Dalvik cache in Recovery. Failing that, re-flash, following the Dummies Guide, again.

Thanks so far.

Sadly i'm having no luck with it at the moment.

As it stands the phone model is GT-i9100P, Orange branded and upgraded to ICS via Kies, which all seemed to go ok.

I've tried the wipes and just still get stuck on the reboot screen with the yellow triangle.

-

I'm thinking about installing a stock Orange update now but does this depend on the kernel also? Would like to just start all over again really

You have two choices as far as I can see...

1. Flash the stock, Orange, ICS ROM via Odin, from here. This will overwrite your current kernel and install the Orange one.

2. Since you do not have the exact kernel details to hand, you could try flashing this LP7, CF-Root kernel, here.

Appreciate this.

This is actually the first time i've messed a flash/upgrade on a piece of kit for ages.

I'm genuinely usually careful

-

I will try those methods, i also used a program called Fusdownloader which gave me this information regarding my model on Orange.

Product Code: GT-I9100LKNORA
Latest firmware: I9100PBVLP6/I9100PORALP7/I9100PBVLP6/I9100PBVLP6
Modified: 20/04/2012 22:09:50
Filename: GT-I9100P_ORA_1_20120420220937_73eglp6t0d.zip.enc2mod el on Orange.

Cheers again, hopefully i can sort this

Go for the LP7 kernel first... what have you got to lose?

Followed your advice there ironass and i can happily say i've now got a fully rooted SGS2 running the latest Andy's mod and Synah (sp?) kernel.

All backed up and running now, thanks a lot for taking time to help a newcomer

Nice one Bailzebub!

I think you might find that the stock ICS, Orange firmware, for the, "P", variant, has an LP7 kernel. That would explain why you could not get it to work before.

Congratulations!

Can someone pls tell me whether this guide is for SGS2 I9100 or I9100G? As I do not want to spoil the expensive phone. I am only new to this. Thanks in advance.

Welcome to the forum JohnSGS215 and thanks for joining.
The guide is for the i9100 but it can be applied to the G variant. If you have the i9100 follow this guide to the letter. But if you have the g use this guide as instructions on how to root but DO NOT use the cfroot kernels. Get your kernels from post #2 of this thread

That rather depends on how badly you plan on fouling it up!

If you want to, you can re-flash your original kernel back again. If you, "brick", your phone, by, say, yanking out the USB cable during the rooting process... that could be a little more involved.

Reading through the thread mentioned above, the, "Lucifr", kernel seems to be the most popular for rooting, see here.

Since you have the, "G", variant, (judging by the kernel version you have posted), of the Samsung Galaxy S2 this thread should prove very useful and this post in particular, by Shotgun84, describes your kernel and how to root it and can be used in conjunction with this guide.

I would suggest, strongly, reading the, "G" variant thread, thoroughly and carefully, as this applies directly to your model of handset and is tailored for the, "G", users.
