So let me see if i understand this correctly. From what i have read, it looks like i cant install CWM recovery without installing a custom Kernel? So me backing up my stock set up is pretty much out of the question? So everytime i wish to install a different custom rom i am essentailly reinstalling CWM recovery as well?
How can i backup my stock set up and restore it if i screw something up, or install a rom that i am not happy with? I am coming rom an epic 4g on sprint and it was different with that galaxy phone.
Flash a CF Root kernel that matches your firmware, create your near stock b/u. This will be your point to fall back on. 99.99% of ROMs you flash will include a kernel, that also has CWM, it may be a different version but they all work the same, for the most part. The majority of kernels include CWMr 5 or higher.
You'll always have the option of restoring your "stock" b/u so long as you don't delete it. Titanium b/u is the ticket to back up all your apps and their data rather than having to extract those apps/data from a CWM b/u.
You only have to root once. The easiest way to unroot is to flash a stock firmware. Flashing a stock kernel back on after you've rooted will replace CWM recovery with stock recovery, but you'll remain rooted. Probably doesn't address all your questions, but you've got a start.

forgot to mention that i am rooted now. using oneclickroot.
Just flash a custom kernel with CWM recovery installed inside.
Such as:
- Siyah
- Phoenix
- Ninphetamine
etc...
DO NOT FLASH STOCK KERNEL AS IT WILL DELETE CWM RECOVERY. ROM MANAGER DOES NOT INSTALL RECOVERY ON YOUR PHONE.

is it as simple as using Odin, clicking PDA and flashing the downloaded kernel? and there should be no side effects from using a custom kernel such as Siyah?
Getting back to 100% stock is easy, odin flash a rom.
CF root *is* the stock kernel, just with some bits added (CWM recovery and root).
CF root with your stock rom is defo the safest bet.

Yes if you get the kernel in odin tar file, otherwise flash CF root and use CWM recovery to flash the zips.
Hi All
Please let me explain in detail:
1. I had original ICS and flashed CF-Root with ODIN
2. Flashed new JB-Polland with ODIN
3. Lost root access and CF apps
4. Re-flashed CF-Root, CF apps and root access granted
5. Opening CWM i get the following msg: "This version of CWM should be used with CF-CWM v1.1" Now from reading other posts, i think this error is due to CF-Root not supporting JB.
Therefore what are my options?
1. Can I flash a new root over CF-Root, that supports JB.
2. Do I do the triangle away and try to clear CF-Root
3. Any other suggestions?
Thanks in advance guys.
Whenever I'm flashing a ROM, I flash over the previous one.
I installed CF-Root, flashed MIUI, didn't like it so flashed CM10, didn't like it so flashed to stock again then reset my flash count to 0.
Or use it as is. Everyone who uses CF-Root with JB gets that message. You can still perform backups, updates and ZIP installs through CWM recovery.
Thanks Sleepycat, I didn't realise you could keep using it. Part of the message says some features have been disabled.
Running backup in recovery mode now and seems to be going sweet.
Thanks Guys
its just the app that's incompatible, not CWM itself.

Depending on what you are flashing, what is on the phone will be "overwritten". For example if you flash a kernel you will replace just the kernel, if you are flashing a full rom, everything that the rom contains will overwrite its equivalent in the phone (which is why you needed to reflash the root).
If you want to ensure you can get back to original state you needed to have done a nandroid backup at the beginning from which to restore later.
Hope this helps

Guys I need help with rooting and installing CWM recovery on my phone so i can install custom roms. Im running on stock 4.03 ZSLPE...What is the safest way for me without bricking my phone. Because 1 of my friends super bricked his phone after trying to install a custom rom..Plz help
Try cf-foot ( kernel ) or try the zip methord ( i forgot the link , search in google ,this is a little bit safer )

Cf root will give u root and CWM recovery, so u're be able to install custom rom
1. Download any version of CWM from here
2. Get desired rom (kernel too if you want)
3. Place everything in Externel SDcard
4. Boot into stock recovery (Power+Home+Vol up)
5. Use stock recovery to flash CWM
6. Backup Current stock rom
7. Wipe the usual
8. Flash Custom rom (Or just kernel)
9. Reboot
10. ?? Profit ??
Now you got Custom rom or Kernel + Full stock rom backup (can always get stock rom from sammobile if you lose it)

Thank u for the response. But im a bit scared flash or wipe in temp touch recovery. Because a friend of mine got his s2 super bricked while trying to flash on stock 4.04 kernel. does this emcc bug affect 4.03 stock kernels as well? So can i just flash the latest Siyah Kernel using ODIN ??
Any time you root/flash a Rom theres a chance to brick your phone. What -Grift- said is the easiest and best way to flash a custom Rom in my opinion. Just make a Nandroid backup, delete data and cache, install the zip file from your SD card. I've flashed 4 Roms so far with this phone, all successfully. Currently I'm running Cyanogenmod 7 on my DINC 2. Good luck on whatever method you choose.

Go into download mode, connect your phone to your computer and use Odin to flash a custom kernel to your phone. That done, you have root and you're safe from the emmc superbug. (EDIT: although 4.0.3 doesnt have the bug, if thats what is bothering you) You can then flash a custom rom or whatever else you please. Use the TAR version of siyah v4.1.5 from www.gokhanmoral.com
Instructions on how to use Odin are available all over this site and on the web in general. Search and you'll get it.
If you don't wanna use Odin, your only other option is flashing temporary CWM. Search for rachmat3's method or use the one mentioned above. All three are equally safe provided you read up on the procedure adequately.
99.9% of the phones getting bricked is coz people jump headlong into the procedure without first bothering to educate themselves on how to go about it. They get what they deserve.

If noobs on xda have taught me one thing, its that smartphones just aren't for everyone.
Or just wipe only when you have flash the rom (custom recoveries are safe e.g siyah dorimanx)
Edit: AFAIK 4.0.3 are safe the bug is with leaked 4.0.4?

Thank you for the info. I know few things about rooting and custom roms. I have flashed so moany roms with my HTC. Im new to samsung and odin. Thats why i wanted to make sure before doing anything stupid.
Thank u all for the help. I successfuly flashed Siyah kernel to get root and CWM
I am aware that this has been asked before but there are conflicting answers withing the threads that I have read.
I am running 4.1.2 WLSW having worked my way through the various jb releases over time. Root has been retained using everroot in mobile odin. The kernel is stock.
Having decided to install a stable release of cyanogenmod (10.1.3) I have been reading around for days to avoid pitfalls or to know what to do should a problem arise.
The only one thing that I am still unsure about is whether it is indeed safe to use a temporary cwm (flashed via stock recovery) to install cyanogenmod. I have downloaded the latest temporary cwn from the rommanager site and it appears to work just fine - I have created a backup without issues so I can get back to where I am now if I don't like or have problems with cyanogenmod.
I was planning to flash [KERNEL] ClockworkMod Recovery 6.0.2.9 from this thread http://forum.xda-developers.com/showthread.php?t=1118693 - but in the last couple of pages in the thread there are users that have had boot failures after flashing it. This is what has lead me to ask the question is it safe to use the temporary cwm?
I am aware that there are other kernels that I could use (Philz/Siyah) but would like to know which cwm is safest/best for the installation of cyanogenmod.
Install philz kernel by flashing in stock recovery and put that zip on ext sd. Stay away from rom manager. Dont use it. When you have philz installed make a nandroid bkup and make sure preload is included too. Also bk up you're efs folder with ktool free from playstore. As you have root get that and bk efs up asap. once you have done a nandroid bkup and done the efs bkup then flash cm. May be good to get a copy of you're modem now too.

I have backed up efs already using ktool and have already made a nandroid backup using temporary cwm - good advice none the less.
I have read that rommanager is problematic with the i9100 so am not planning to use it.
My method of choice to flash Philz would be mobile odin (unless there is some disadvantage by doing it this way?).
Regarding my modem, it is included in the stock firmware so I could flash just the modem from this using mobile odin if I have trouble (I have assumed mobile odin works in cm).
My original question remains however - why not use temporary cwm?
Mobile odin will work on cm. And yes you can flash with temp cwm. Get you're modem from here on xda. Makes no odds how you flash philz Use odin or recovery its up to you.

If I can flash with temp cwm, there is no need to flash philz at all - or have I missed something?
If you flash with temp there's no guarantee. Philz then flash is a safer way of doing things.

Presumably the latest Siyah kernel will also do?
Yes that's ok
It's simply a matter of preference.....temporary CWM is as it 'says on the tin'........temporary....
You have to reflash it every time you want to use it.
PhilZ is permanent....once it's flashed, it's there, no further action needed, plus it has a touch interface unlike regular CWM......
If you intend to stay with stock, but want to have the advantages of CWM, then I'd advise go with PhilZ...purely because a few steps less are necessary to be able to use it.......
(Enter stock recovery, flash CWM then use CWM to flash whatever..... every time with temporary CWM)
If you intend to flash a custom ROM, it'll come with its own permanent CWM anyway (which will overwrite the PhilZ kernel and/or remove the need to continuously reflash the temporary CWM)

Thanks for the advice folks. I flashed Siyah then installed cm 10.1.3 and the associated gapps. All went without a hitch. I was actually surprised how quickly the process completed. I had the rotating cm boot image less than 2 minutes after starting the install from first zip.
Off topic, but I am totally impressed with the cm ROM. I find my frustration at constantly waiting for phone manufacturers to catch up with vanilla android releases has completely melted away.
Glad it's sorted :thumbup:

Download HC ktool from the market, create your efs backup with it and use a root explorer to copy it to an external removable micro SD card......

For rooting I will use Framaroot.
For installing CWM I believe that you can install it via ROM Manager, or you can install the ROM directly via Mobile Odin.
Sent from my GT-I9100 using Tapatalk
OK....first....
Why look elsewhere for rooting methods? Everything you need is right here on XDA.
Second.....NEVER use ROM manager on an S2.....it breaks things.
Third....mobile Odin can only be used on rooted devices....primarily for flashing stock firmwares.
What version of android is on your S2....GB, ICS or JB?
This might be my S2, or it might be my W...but it's definitely CM
Yes, I found Framaroot here and am planning to use it for the rooting purposes.
Thanks, good to know. So I will need to install CWM manually I guess. Somehow.
What is it that Mobile Odin does, is it an actual reovery ROM itself or does it install CWM which in turn installs the ROM?
But I can use Mobile Odin to install a custom ROM I think?
I am 4.1.2 JB
Sent from my GT-I9100 using Tapatalk
Mobile Odin is a phone based version of PC Odin.....it is designed to flash back to stock from a rooted modified phone without the need to hook the phone to a PC....
You're on 4.1.2.....
Search for the PhilZ thread.......
With the downloads contained, you can root and flash CWM via the stock recovery in one flash.....don't get much easier than that.......
This might be my S2, or it might be my W...but it's definitely CM
I can root it and flash it in one step? I've found like 50 guides but none of them as simple as you're suggesting.
There are so many ways to do each individual step.
I reckon the steps after that would be to install my custom ROM via CWM via SD card. Clear/Wipe cache and install the custom ROM again?
Sent from my GT-I9100 using Tapatalk
Edit: How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
As I said........easy.....
1) flash PhilZ via stock recovery to root and flash CWM
2) At this stage your phone will still boot normally and allow you to download HC ktool in order to make your EFS backup. It might be an idea to make a full backup (nandroid backup) of your current setup using CWM too....
3) use CWM to flash the ROM (and it's associated gapps package) of your choice.
4) use CWM to perform the cache, dalvik and data wipes.
5) reboot, perform initial setup download user apps.......
Job done.......
This might be my S2, or it might be my W...but it's definitely CM
You could also juse Siyah Kernel, a good alternative to philz:good:
Except that it can't be flashed via the stock recovery.....it has to be flashed via Odin......
This might be my S2, or it might be my W...but it's definitely CM
In which way does a Kernel replace a rooter/bootloader flasher, are these not different things?

I very much appreciate your help Keith. I've been on numerous forum but never got this good feedback.
I searched the PhilZ thread and got so many results. My model is i9100 of the Galaxy S2, I guess the methods you have been describing works for this model?
I need to backup program data and EFS before I dare start playing around.
How can I backup EFS before using the technique you mentioned to root/flash CWM in one go, if my device is not yet rooted?
You can't. And you don't need to unless your phone is rooted, because if your phone is rooted nothing you can do to the phone is capable of borking the EFS/IMEI.
Edit - Also, I'm detecting a lack of knowledge of 'the basics' in the threads you've posted recently; I strongly suggest you read all the guides/tutorials stickied in the thread near the top of the General section before you do anything to your phone. A lack of knowledge exponentially increases the risk of you permanently breaking your phone depending on how little knowledge you have when you attempt to 'do stuff' to the phone.
For backing up the efs you'll need to flash a recovery first (like Philz as already suggested).
But anyway, problems with the efs won't be caused by just rooting so you can go ahead and root first and then use KTool.

Thank you. As I want to perform all the necessary steps directly on my phone, I am now thinking of doing the following.
Installing Framaroot (APK) and rooting my Samsung Galaxy S2 i9100 (http://forum.xda-developers.com/showthread.php?t=2130276)
Installing KTool and backing up EFS to external SD-card
Installing Titanium Backup (Root version) to backup AppData
Alt 1.) Downloading Mobile Odin to OS. Flashing ROM + GApps via this. But this keeps my stock recovery? (http://forum.xda-developers.com/showthread.php?t=1347899)
Alt 2.) Downloading PhilZ Touch Recovery 3.0 for Galaxy S2 i9100 which flashes + re-roots for me (?). Not sure if it's the right version as the post is old? (http://forum.xda-developers.com/showthread.php?t=1840223)
Alt 3.) Flashing CWM via Mobile Odin, and then in turn boot to recovery (now CWM) and flashing ROM + Gapps via CWM. This should update my recovery as well as my ROM?
After flashing ROM, entering recovery to Wipe Cache, Dalvik and Data
Flash ROM again as previous step supposedly deletes the ROM?
Boot ROM, Configure, Install Apps and restore App Data
Does the above look correct?
Is the version of PhilZ the correct one? It appears to be a 'temporary recovery' rather than a permanent, which might be what I am after if I want to flash the current version of CWM for Galaxy S2 from www.clockwerkmod.com/rommanager
Follow the instructions I gave in this post....
http://forum.xda-developers.com/showthread.php?p=48583106
and you will have a rooted phone running a custom ROM. No need to reflash the ROM after the wipes. Wiping cache, dalvik and data will NOT erase the ROM, all it'll do is erase any personal settings and downloaded apps.
Mobile Odin can't be used to flash custom ROMs, I think it can be used to flash CWM.... but only if you can find a compatible version in a .tar format.
PhilZ is still your best bet.....you will root your phone and install CWM in one hit.....all from your existing stock recovery. The CWM inPhilZ is NOT temporary, though it WILL be overwritten when you flash the ROM which will contain it's own permanent version of CWM. Just match your phones build version to the PhilZ kernel that you download.......
Why make extra work for yourself by increasing the number of steps you have to take (use framaroot then try to find a compatible CWM) when you can do it in one step?
And as mentioned before.....DON'T use ROM manager on an S2.....it breaks things....specifically recovery....one of your prime goals.....

I made big projects of things. As a complete novice within Android, I've read through numerous threads, made project notes, consolidated info and made Mindmaps to understand this.
From my understanding, a kernel (I've seen Siyah mentions on many places) is the interpreter between hardware and the instructions given by the software.
In which way is this comparable to a recovery partition/ROM, namely PhilZ?
I'm sure it's some detail I'm missing, and thanks for the tip.

Thank you once again Keith for your engagement and good tips.
I think the reasons why I am considering the different options, and also trying them out - is to get a broader understanding of Android and the alternative processes as I approach my goal of flashing a new ROM.
1.) So far I installed Framaroot and rooted the device successfully.
2.) I then downloaded Hellcat's kTool and made an EFS backup (and a kernel dump, whatever that is)
3.) Then I installed Titanium Backup and backed up all user + system apps (+data I think)
4.) I then downloaded CWM from www.clockworkmod.com/rommanager > recovery as a zip, booted the stock recovery and started CWM (locally, without replacing stock recovery for some reason), from which I did a full Nandroid backup (with stock recovery intact in this backup, I guess. Device was however rooted so it's not fully original).
I reckon I now just need to download my custom ROM and it's relevant Gapps.
I have read good things about Mobile Odin, and since a while back it supports *.zip files so I believe it is a good alternative for flashing custom ROM's now as well.
PhilZ was a bit intimidating, as there was a general thread and different model based threads in each subforum. They were also in different versions, dates and basebands. Also it appears to be available in a "permanent" download as well as a "temporary", which caused my confusion in the last thread.
I did not know that the recovery was replaced when installing a custom ROM, as I did not know that they contained their own partition of a recovery ROM.
Thanks for the information about not needing to re-flash ROM after the relevant wipes.
Thanks for the discouragement of ROM Manager, I promise to stay away from it.
From my understanding, PhilZ seems to be a modified version of CWM6, which includes ChainFire's Auto Root and some other add-ons as well. Is this a correct understanding?
You don't need to backup system apps/data from Titanium Backup because restoring them on a new rom will definitely cause issues.
Plus in case of a bad flash or something nandroid is always there for you so before doing anything new with the phone always do a nandroid backup.
