root cutom ROM recovery - Galaxy S II Q&A, Help & Troubleshooting

Hello
I have a Samsung i9100G running ICS 4.0.3, build no. iml74k.jplp6, baseband i9100gxxlpr, and kernel is 3.0.8 [email protected]#2
I used to have it rooted via "one click root", and had CWM recovery.
After installing Slimkat rom, the recovery automatically became TWRP.
One of my friends wiped the entire phone, and the only way to fix was to restore the original FW "I9100GJPLP6_I9100GOJPLP5_I9100GXXLPR_HOME.tar".
Now, I can not root it, install CWM or TWRP recovery to install any other ROM.
I have searched a lot on xda but I am a rookie.
What I know is I have to root first then install custom recovery, but I can not find the root tool for my device and the custom recovery.
Flashify, rom manager, and other tools always see both recoveries but can not execute anything.

You could try to use different root methods. I used KingoRoot for PC to root mine. Hope I got your problem...

Why cant you root it?
Can you boot into recovery of Stock ROM?

KingoRoot does not support i9100g.
I can boot to the stock recovery.

Installing CWM on "rooted" GT-I9100T

So I reinstalled the stock GT-I9100T (Vodafone S2) 4.0.3 ICS firmware using Odin, and decided to use a method of rooting I found online which was simply installing "update.zip" using the stock Recovery. A SuperSU app is present and Root Checker says it's rooted. Now I want to install CWM to reflash AOKP, but I'm not sure what method to use, since it's already rooted.
Thanks in advance.
Save yourself hassles & avoid 'temporary' versions of CWM. Just flash the Odin version of the Siyah build which is compatible with the current Android version you're running. Read the first page of the Siyah threads to workout which build you need. You'll have a rooted phone + permanent CWM & you can then flash any rom/other kernel you like quickly/easily.

[q] looking for root / cwm

Hello, I am just browsing the I717 posts here, being familiar with android root and CWM, I can not seem to find much with root and CWM on the boards here. I see a lot of root, that installs TWRP a lot but I am looking to root and have CWM. Perhaps I missed it, however wanted to ask. Thank you.
Is this the most recent ?

That root method seems to install TWRP, I just want ROOT by itself so perhaps I can install CWM ?
To root this phone you have to flash a kernel that also installs CWR. The only way I can see to get root only without installing a recovery is put the phone in download mode and use odin to flash a rooted rom. But I've never seem an odin version of a rooted rom.
Why don't you want TWRP? Its way better than CWR.

Latest CWM is 6.0.4.3
You do not need to install a custom kernel to root your phone. Use Odin to install CWM and then use CWM recovery to install a version of superuser.
Easiest method I know is here: Works for jellybean also.

A little information please ?

I have trued to read and search the forums, but I haven't been able to figure a definitive answer to this...
When I flash CWM on my S2 using Odin, does it root the phone ?
I usually Root (with framaroot), Flash CWM, Flash CM 11 nightly, Re-root using framaroot.
But Can I just do : Flash CWM and Flash the CM 11 nightly ? does it auto root ?
What do you mean, 'usually'? Why is it that you can't just flash each new build of Cm11 from the previous one? Why do you need to re-root in the first place?
When I rooted my phone, rather than using a one-click such as framaroot, I flashed a kernel (siyah in my case) using Odin. That gave me CWM and root. That cuts out the step you're trying to to eliminate, if I've understood your question correctly?
I'm not sure in answer to your direct question, try it and see. Hopefully the alternative method I just gave you makes it a little quicker though
Edit : you could, if flashing CWM only doesn't give you root, just flash SuperSU from there and then continue.

Well mate your question is tricky to understand :cyclops:
1. NO installing CWM wont root your device requires another process (such a framaroot)
2. Aftrer installing CM 11 you dont have to re-root the mobile because CM comes prerooted with superuser !!
3. if you had already managed to install CM 11 think that you have already rooted your mobile
just for typing the 3 points my head spins in short no need for rooting after cm 11 ....and NO cwm wont root your device

Thanks for taking the time to reply.
Why do I have to install CWM if I'm already rooted ? Can't I just framaroot then install CM 11 ?
Can I do a CWM, Cyanogen install without rooting ? Since CM already comes rooted. So jut CWM using odin, then CM install ROM. ?
Other question, Let's say I root, flash CWM, flash a ROM (any rom), can I be unrooted after that and have to reroot again ? Or do ALL roms come pre rooted ?

CyanogenMod comes rooted. Also, the default recovery on CyanogenMod is CWM as well, so you can boot into recovery with volume up + home + power and flash a new build from there. You don't even need to use framaroot or flash CWM using Odin...
And yes, most (almost all) custom ROMs should come rooted unless you're flashing stock Samsung ROM through Odin. Besides, if you're flashing something in recovery, I don't think you need to be rooted.

Just to make sure that you understand everything i'm segregating your questions
1.Why do i install CWM when i'm already rooted?
Rooting is a process which just gives your overall control to your device, but just rooting wont make you eligible to flash any ROMS. Now when your install CWM (Clock Work Mod) its a unique type of recovery which enables your to flash Custom Roms. Your ordinary stock rom (your samsung firmware) also does have a recovery (stock recovery) which cannot penetrate into system files. So CWM is a must to flash roms !
Can i do a CWM and flash Cyanogenmod?
Absolutely NO!! Just because CM comes prerooted doesn't mean that you can flash CM without rooting.. CWM requires root to flash and change system files. For instance your are in Stock Samsung Firmware not rooted you just install CWM flash Cyanogenmod and you'll end up in a bootloop or softbrick. Since your system didnt allow files inside coz no ROOT!!..In the other hand if your already running Cyanogenmod (any version) you dont have to root nor flash CWM because they come prerooted and preinstalled with CWM.so you can flash on the go
Let's say I root, flash CWM, flash a ROM (any rom), can I be unrooted after that and have to reroot again ? Or do ALL roms come pre rooted ?
Well cyanogenmod has an inbuilt function to disable root and most of the Roms comes with it now it can be found in settings >developer options> and root access...but not all roms im assuming. on the other hand yes some roms never come prerooted such as (omni rom 4.4.2) where you have to flash superuser to get root. But as i said incase of all prerooted roms there is an option to disable root
hope this helps you understand about rooting and cwm :good:
Thank you both for your answers, I understand much more now.
BUT
Last two answers are in conflict. They say the opposite.
which one to choose ?

[Q] Rooted. unable to Flash Recovry

I rooted my Galaxy S4 using: http://forum.xda-developers.com/showthread.php?t=2290798
Rootchecker shows root access. However, I cannot get TWRP or CWM to flash. I tried CWM through ROM Manager and TWR through GooManager. ROM Manager reports a good install but when I reboot to recovery it is stock recovery.
Any help would be appreciated.
Please tell me you're already read the (many) threads about basebands and build numbers and custom recoveries.

this may assist U
Plenty of threads about this but let me help you out here.
What build number are you on? Any build number other than MDK have no known way to flash a custom recovery due to a locked bootloader. However if you read into some of the safestrap threads you can install a select few modified roms built for SS.

Confused about rooting, recovery and custom roms

Could someone provide me with an easy guide to rooting, installing recovery and installing a custom rom on my S2? I1900 version.
I'm wanting to put a KK rom on it but I'm confused about which recovery to use and the best method for rooting.

I read your post on another thread you said you have flashed siyah kernel, so you are already rooted. You just need to use a "kitkat compatible" recovery such as CWM 6.0.4.5+ or TWRP 2.7+ to flash kitkat roms
Just a quick google search for "kitkat compatible recovery" gave me this one. Just download the CWM .zip, flash it from siyah recovery, then reboot to recovery(not system), then do your wipes/backups and flash the rom and gapps you want and reboot to system. Done
will give this a go!
