First of all, I like to say Thank you to the author for this brilliant guide.
http://forum.xda-developers.com/showthread.php?t=1746794
I’ve always wanted to root my phone primarily to make backups and being able to freeze/uninstall bloatware that came with the stock rom is a treat. Anyway to cut to the chase I used method 1 as suggested and now I’m a proud owner of a rooted galaxy s2.
I have a few questions I’ve been searching all over the place on this forum and elsewhere on the internet I was wondering if someone can shed some light. I’m sorry if these questions or similar have already been posted in the forum.
Previously, I have tried a method where you need to flash an insure kernel, root with Samsung Quick Root (aka S2 root), and flash back to stock/secure kernel (optional). Now if I wanted to use ROM Manager to flash CWM recovery it simply wouldn’t do it, even if I try to run the package (update.zip) from stock recovery. Maybe it’s to do with the stock kernel? I really don’t know maybe someone can explain. So the problem is if I can’t boot into CWM recovery, I can’t really backup my phone until I come across this guide. As noted from this guide, so now I can boot the phone to stock recovery, from here apply update from external sdcard to obtain a temporary flash of CWM recovery. Great!
Q. Is this how you backup the entire phone with CWM recovery?
Q. Is root needed to run CWM recovery in order to backup phone?
I’m asking this because I have managed to create a backup before I rooted my phone using method 1. Unless of course the backup created will not restore the phone entirely or simply not work at all. Or the other thing I can suggest is root still exist from my previous attempt but I doubt it as I’ve since flashed back to stock rom via odin.
I noticed with this method CWM is not installed, you need to access it through stock recovery and apply package from external sdcard which is fine by me. If I wanted to install a custom ROM, e.g. MIUI, do I install it via CWM recovery? Sorry all this business with root is still very new to me.
Q. Can I download and use ROM Manager if I wanted to or not required?
Q. As the stock kernel is untouched, will I be able to boot straight into CWM recovery from ROM Manager, without having to go through the apply update from sdcard?
Q. Using Titanium backup, why does SuperSU not on the list?
Thank you
Firstly, you should have used CF-Root as it is just a modified version of your stock kernel to grant to you Root and CWM.
Yes, root is required for CWM to work.
Yes, CWM is used to fully back up your phone.
Don't use ROM Manager with CWM or you'll have a bad day.
No idea why SuperSU isn't appearing. Does it matter?

I know you said earlier you wanted minimal involvement with rooting, but I strongly suggest popping a rom on your phone. Try out cm9 and if you don't like it you can always flash back.

Just think about this: why would you need root in your current ROM to run clockwork mod RECOVERY?
Whatever recovery you are using (3e, Clockwork, Amon-Ra, RAZR, it doesn't matter) will work completely whether you have root or not.
Thanks for your reply. There are many ways to root. I guess each method will have its advantage(s) and disadvantage(s). Please could you explain why CF-Root is better? And if I want to use CF-Root now, can I still Un-root (method 1) and root again with CF-Root?
What happens if I want to un-root and return to my stock kernel? Can I do that after applying CF-Root? And lastly, would it be all right to run your phone long term with an insecure kernel? BTW, what exactly is an insecure kernel?
Oh, if root is required for CWM to work, why was I able to create a backup without root in the first place? Just curious!
I will most probably try out various custom roms out there just taking things a step at a time.
Thank you again

CF-Root is better because it is ridiculously easy. Flash kernel via Odin. Done.
To unroot you flash an official firmware image also via Odin and it will erase all non-standard content from your phone.
To confirm: whatever recovery you are using is not interested in whether you have root permissions in your rom. Its functions do not encounter them at all.

Thank you alc027 for your reply. I guess the one thing with CF-Root is you’re stuck with an insecure kernel. Flashing an official image will revert to stock but root will be lost and you’ll have to reinstall everything from scratch even if you have Titanium Backup its purpose is defeated. Unless of course like you said CWM doesn’t require root to run and a backup was created with all my apps installed I could restore it to point of the backup just like an image backup for your PC. Thank you for your help. Much appreciated.

I don't know whether that's true. I think the insecure kernel is only insecure in that it will allow injection of the su binary via super one click. Whether CF-Root is insecure or not really doesn't matter to anything. For that matter why are you concerned about being left on the insecure kernel?

Actually I’m not really concerned, I guess I’m just curious and want to know the main difference between secure and insecure kernels. I suppose you’re right it doesn’t really matter if it’s left on the insecure kernel. I mean unless I’m selling the phone in which case I’ll probably have to flash to stock rom anyway.
With regards to nandroid backup, I’ve read from this guide that it’s important to backup the EFS folder.
http://forum.xda-developers.com/showthread.php?t=1592104
Well is this particular folder backed up when using CWM to backup phone? Incidentally, does CWM backup EVERYTHING other than the external SD card?
Thanks again in advance
Insecure kernel allows adb access from usb, that's it.
If you do not use cwm manager, bundled with cf root, then you do not need cf root to root. Better stick to the method with cwm: no yellow triangle and no counter increase, busybox is installed and kernel untouched. These are advantages over cf root for who needs them
That way, every one is satisfied

Thanks for the info Phil3759. I haven't properly tried ROM Manager. Is it a good idea to use rom manager or in this case cwm manager that comes with cf-root to flash different roms? If I'm not mistaken flashing to other roms can be achieved via cwm recovery is this correct?

Hi guys, I just got my GS2 (not rooted yet, entirely stock)and think I understand how to flash a new ROM (UnNamed), but I want to make sure that this is the right way before I possibly screw my phone up. Here's how I understand it:
1) Load the kernel (Entropy's Daily Driver) onto the phone with Odin
2) Put the ROM onto my SD card
3) Go into CWM, Backup phone, then go to load from SD card
OR, can I just do #2 and #3?
Thanks a lot guys, It's great to have such an awesome development community for an already awesome phone.
Follow ALL those steps and your good

Entropy's daily driver kernel is ClockworkMod Recovery flashable, you can't flash it with Odin.
What you can do is extract the zImage and flash with heimdall command line, adb, or Android Terminal Emulator. If you need step by step instructions, see my guide.
After that, your steps 2 and 3 are good.
Yeah, just noticed that Entropy doesn't actually have any .tars on the page. Could i flash codeworkxs kernel and the root with superoneclick (option 3 on FAQ thread), and then flash UnNamed through CWM? Is the kernel included in the UnNamed file, or do I have to flash them both separately? Thanks.

Yes, except no need to root. Just Odin codeworx kernel, push UnNamed install zip to root of internal sd card, boot into recovery and install from sd card. UnNamed is already rooted with latest versions of su, Superuser, and Busybox. UnNamed already includes the latest version of Entropy's daily driver. When you Odin the custom kernel, you'll get the yellow triangle and increment the flash counter.
Edit: looks like creepyncrawly beat me to it
That will work but it will trip the flash counter. Not a big deal but some people don't want to risk voiding their warranty.
Unnamed rom contains entropy512's kernel.
I'd recommend following what creepyncrawly said. Better safe than sorry in my book.
Sent from my SAMSUNG-SGH-I777 using XDA App
OK, I'll use creepncrawlers method, thanks a lot for the help guys.
If you want to do it without tripping the flash counter, you need to flash my prerooted system image in Odin (that IS available as Odin-flashable) and then flash a custom kernel from that using creepyncrawly's "no triangle" guide.
But as long as you get rid of the triangle (this can be done "after the fact"), most places you might return the device to don't check the flash counter if the phone boots without the "custom binary triangle warning" screen.
Oh also, one other noob question, when you flash something from a microSD card does it get copied into the internal memory, or do you have to always leave that card in the slot?
When you flash something it 'installs' it. So the original file can be deleted afterwards.

Greetings!
I'm a noob.
I'm completely confused with upgrading to ICS, "Rooting" and installing custom ROMs.
I currently have Android 2.3.5 and some custom ROM installed (On power on a Yellow exclamation mark appears.. I think it's relevant)
In "about phone" it says the Kernel version is:
2.6.35.7-i9100xwki8-cl616395 [email protected] #2
What I'd like to eventually have is a phone (perhaps rooted) with ICS and the ability to install custom ROMS.. How on earth do I get there?
Thanks in advance!
and pardon the Noobness..
Well the yellow exclamation mark is caused by an insecure kernel. Anyway, just download Chainfire's KI8 CF-Root, and flash it through Odin. Then you will have root and Clockworkmod Recovery, and then you can flash to your hearts desire.
Sent from my GT-I9100 using XDA
Doesnt the exclamation mark on the boot screen mean he is already rooted?
From what I understand your phone is al ready rooted..(triangle in boot) If yes you can flash whatever rom you want already...
You can search here there are a lot of nice roms...
If you want just ics you can flash an original rom from here You can download wherever you see 4.0.3 version. Its ics!
On the other hand if you're not rooted themadba has already answered..
This is a very good guide.. http://forum.xda-developers.com/showthread.php?t=1125414
Not always. I had an insecure kernel flashed FOR root but I didn't have root yet. All the OP has to do is flash the KI8 kernel and he will obtain root.
Sent from my GT-I9100 using XDA
Go check out the video tutorials at galaxys2root.com. They'll walk you step by step through everything you need for rooting and installing.
Yeah in the 'old days' you had to flash an unsecure stock kernel so an app like super one click could root. So its possible to have triangle but not root
Triangle away or a jig can clear the counter easy.

Thank's all for your replies!
According to "root checker" (an app I downloaded) my phone is rooted.
Now, if i understand correctly in order to install a rom or a new version of an OS i need to place whatever installation files on my SD card and then "reboot into recovery" and choose one of the options there (falsh from card, run zip etc.)
I have Rom Manager installed, so that can reboot into recovery.. if that's what needs to be done, that is.
That about right? Is this called "flashing"?
Do not use Rom Manager & CWM on the same SGS2.
Choose one or the other. Yes, I realise Rom Manager premium has a few more bits of functionality over the non-paid version & CWM, but if you continue to have/use both on your phone you will have problems eventually.
Rom Manager tends to either break Recovery and/or cause bootloops.

Rom manager tells me I must install The CWM in order to install roms.
Which app should I use instead? Do I need some sort of app to actually install ICS?
Whenever you want to install a rom, boot into CWRecovery. I've always done it this way & have never had a problem. If you've rooted your phone & have CWM installed, that's all you'll ever need.
Apart from the one time I thought I'd buy Rom Manager premium from the Market. Broke my recovery & put me into bootloop. Fortunately for me I do a backup whenever I make changes to my setup (flash a new rom or kernel) so I fixed it easily.
As I said, use Rom Manager & CWM on the same phone at your own risk.
ok, I uninstalled the Rom manager.
I finally figured out the Volume UP + Home + Power which allows me to boot into recovery. (very noob, remember?..)
Is there an easy way to copy something like an ICS installation file to the SDcard and run that from the recovery menu? Or must I use one of them Odin or Kies for that?
If such an "installation file" exists, where does one find it?
If you want install one of the original firmwares I posted you previously, you need Odin. Don't worry is very easy a way.. If you want other roms such as CM9 or resurrection you'll have to copy the files to sd and install them as you said from recovery..
Don't worry we were all noobs once.. These are easy procedures
And one more: you said something about kies.. You just need kits for it's divers.. You can't flash out install anything from kies.. And it's very important to close it(and every other procedure comes with it) when you are using Odin...

A very simple question. I wanna root my S2 (UK Sim Free ICS). I don't wanna use CF-Root Kernel. I wanna root it the way I rooted it last time, i.e. using an insecure kernel by Odia. Odia has not published any working insecure kernel for ICS (I have tried using various some kernels for 4.0.3 and some for gingerbread, none of them worked... obviously). So, all I want is an insecure kernel so that I can root it using ADB. I don't mind making an insecure kernel myself, if someone can teach me how to. Hoping for a quick reply.

Can I ask why?
Cf root adds root and it's own manager to the stock kernel. Nothing more.

Nevermind.
I did try CF-Root. I wanna keep my phone close to stock.. as much as possible. Plus I don't want CWM, so is there any way of rooting via CF-Root and then uninstalling CWM? I tried the ADB commands, but they don't work.
Easy fixed. Someone thinks they know what they're talking about (and is unable to use the search function or Google), yet they're expecting their hand held. Just another day on XDA.

Let me tell you one last time, if you know this than you are wasting your time....
When you flash cfroot you get root and the cwm manager. When you flash stock kernel back you are now 100% stock.
Cwm manager app left is like any other app you use, you want to get rid of it use root uninstaller or root explorer and remove/delete the cwm manager apk.

Finally, a proper answer.
Ya, I checked out the option this morning. But haven't tried it yet. I rooted my phone using CF-Root and I have an issue with ad away as well. Anyhow, I was suspecting that this option would give u a temp root, as in after a restart it would go away.. is that true? Also, did it increase your custom binary counter? and what about the yellow triangle?
No yellow triangle because the kernel is unchanged. I doubt the counter has altered either but I don't know how to check it (or what it said before ).
The root is permanent and survives restarts.

Oh.. thank God for u are gonna stop posting, as it is you have been of NO help.. Also, there is a difference between a stock kernel and a stock ROM.

Hi guys,
Firstly apologises in advance, I'm using my phone to browse so trying to navigate what I need to know.
I be using this guide to root, I read it several times and it makes sense for me.
Before I root though and this is a huge factor, is there anyway I can save all my current apps and restore them after flashing a new rom?. I know titantium backup does this but you need to be rooted to achieve this and before you root I understand you need to have a clean wipe for the phone which I haven't done yet since I'm hesistant reinstalling the apps all again 1 by 1.
Thanks

You can use that guide, sure. But I find CF-root to be even easier, as you don't need to use an outside application. Just flash the CF-root kernel for your build of android. Done.

Thanks, I'm still new to this trying to understand everything before rooting.
So backup efs?, what is it and does exactly.
I was under the impression that once I should pick the kernel closest in the about section?.
you will only be able to backup EFS after the rooting...
first Root with Cf-root then the first thing you do EFS back using Ktool (search on google play)
You'll be amazed how easy it is once you've done it (I did it a couple of weeks ago). It's all available right here.
Pay particular attention to this when choosing the kernel:
Listen closely, for I will say zis only once!
Go to Settings -> About phone -> Kernel Version. Note the string present there:
2.6.35.7-I9100XXKG1-CL349526
What matters most (KG1) in this case, is in bold. Try to find the matching file under downloads:

Good luck dude, let us know if you have any questions.
Thanks UK, so CF root it shall be:
Instructions - ODIN (short)
- Flash CF-Root-xxx-vX.X.tar (from the attached zip) as PDA in ODIN, without repartition. Done.
Correct?
Then how does one flash a rom?.
Yes, you flash the TAR file in Odin.
Flashing ROMs comes after you have rooted. First, you put your desired ROM zip in the root of your internal sdcard. Then once you have installed a CF-Root kernel, your device will have ClockworkMod (CWM) Recovery. You access this by holding Power+Home+Volume (Up) until your phone reboots into recovery mode. Then you simply follow the instructions to flash the ROM (read instructions from the developer and always backup).
^Well that's for custom ROMs. If you're talking stock Samsung ROMs, there are many guides around for installing those.

Yes, you flash the TAR file in Odin.

Ok makes sense.
So flash tar file with Odin giving me Root Access.
Grab the desired Rom, so for example MIUI then can you elaborate on the kernel. Because this is the one things that bothers me the most because I can't get my head around it.
From reading I need to get the kernel closest to the one on my about phone info correct?.
Yes that's right. As in the example, where the kernel version says I9100XXKG1, you find a similar one based on the KG1 kernel.
Ok all makes sense, thanks for all the help.

You should read the guides and faqs everything is posted .
EFS is a backup that allows you to restore your phones EFS folder that contains the IMEI for your phone . Its rare but possible that flashing may break IMEI leading to no network connection .

It's always a good idea to backup - search on the market for some of the best solutions. But honestly, I just winged it the first time I rooted with CF-Root, and went without backup. It's up to you.
But after you have rooted get kTool off the market and back up EFS, put it in the cloud or on your computer so you don't lose it.
Custom ROMs normally require a full data wipe first time flashing, so get titanium backup pro and backup all your apps from there.

I still have a few questions before rooting my phone for the first time.
1) if i root 2.3.6 using the right kernel, Can i still install an ics custom rom like resurrection?
2) if i root stock 4.0.3 Poland version or argentinian version, final result of installing a new custom Rom is gonna be the same because it completely replace the first one?
3) what's the difference between nandroid backup and cwm way to backup custom rom? Do i need to keep my backup inside the phone in order to unbrick it tomorrow, or may i just store it on my notebook and delete it from the phone?
Thanks a lot!!

1) Rooting is just to give you access to CWM.. ergo the ability to install custom ROMS so you can install ROMS after rooting
2) When you flash a new ROM (which is rooted) then you dont have to bother about what did you did before that..
3) If i'm not mistaken CWM only allows u to do a nandroid backup.. And if u want to restore to the backup ( in ur case unbrick :silly U need to have that in ur sd card :good:
Happy rooting.. Happy flashing..
1) Follow whatever instructions the rom you're wanting to use has to the letter.
2) If you install a custom rom, then yes, obviously it will replace any stock rom you flash it over the top of.
3) A CWM backup is a Nandroid backup. It's the same thing. You can store your backups wherever you want. I have my 4 most recent Nandroids on my phone, and I have every backup I've ever done on my phone stored on my PC (and another copy on an external drive I use for backups). So I guess the question you're asking is, can I take a Nandroid backup from ages ago stored on my PC, put it on my phone & restore it. Am I right ? If that's what you're asking, the answer is yes.
Thanks. Actually i was asking in case my phone bricks after installing a new rom. I guess i won't be able to come it back to life if i don t have the backup in the phone.
And one more thing. What is efs backup. Do I also need to do it?
Thanks

Yes. The 2nd thing you should do after your root your phone (first thing is do a Nandroid backup) is to get kTool from Google Play & backup your EFS. Before you install another rom or kernel do both of those.
Keep a copy on your external sdcard & keep another copy on your PC. Just in case you ever need it. We get quite a few people on here every week with IMEI/EFS details gone & most don't have EFS backups.
thanks!
I forgot to ask, is there any real risk at using triangle away app? So far, is it working on any kernel? thanks

I've actually used that app a few times well (about 5) and haven't had any issues but once you get CWM installed and you flash kernels through it you won't get the yellow triangle.

There will always be a risk when using anything that manupulates root access, but triangle away is quite safe, as for what kernel if works on, most kernel threads will say if it is compatiable or not, but only with ICS kernels, not GB kernels.
"...once you get CWM installed and you flash kernels through it you won't get the yellow triangle."
What do you mean by that? I actually don´t need to use the app, because triangle will dissapear anyway after flashing a Kernel?

You will still have the triangle after flashing a new rom or kernel, the best way to get rid of it is triagle away, this app will also reset your flash counter.
Once you get a working CWM, let's say you're using Cyanogenmod 9 and you want to flash over the stock kernel.
You'd put the kernel file on the memory of the device (sdcard) and boot in CWM recover and flash from there and you won't get the triangle.
The triangle won't go away now if you unless you use a USB jig or the triangle away app. So get rid of the triangle now and when you want to try a new kernel flash it through CWM and the triangle won't appear. Flash a kernel through download mode and you'll get the triangle.

Fixing permissions is automatic I believe in CWM recovery. It's an option in the recovery menu. Remember to wipe data and cache (dalvik too) when flashing a next rom or else you won't be able to boot.

Thanks for the info mate
By the way, you should really just buy a USB Jig off eBay for a few quid, it resets the custom binary counter (on old bootloaders) and can also force your phone into download mode after a bad flash. Handy to have around. Also, now that you have rooted your phone, download EFS Pro (found here on XDA) and back up your EFS folder before any flashing. Lose this folder and your in serious trouble!

Hi! When rooting or flashing a custom rom or kernel, do I lose internal sd card content?
Where is the EFS folder I need to backup?
Thanks!
