Hi,
Ive taken the plunge and decided to upgrade to the galaxy s2 from htc desire , ive enjoyed flashing the phone for many months so understand clockwork recovery but i want to check as ive been reading the various guides in regards to rooting the galaxy.
From what i understand it seems fairly straightforward ie i root the phone with odin which install a custom recovery which is clockwork same as desire.
My question is when i come to flash phone (which i get monday) i just flash the rom same as desire, ie go into clockwork recovery wipe all factory data reset ... and just flash rom ?
Just want to make sure i got things right before i continue with flash ...
Flash CWM and root via Odin .
Root + CWM .

Hi I am going to be rooting this phone soon but before I do I want to make sure I fully understand everything I do because I am nosey and this is how I learn. So I ask alot of questions usually NOOB questions.
So As I understand it All I have to do is install a custom kernel which has clockworkmod on it. Now when I do that is CWM installed on the recovery partition of the phone so if all else fails I can still get into CWM to install a backup? I know if you use rom manager it fake flashes and the only way to get into CWM is through rom manager and mif the phone wont boot you are screwd. Also this phone has download mode is that a factory way to flash things? Like when I install a ROM do I flash it in download mode or do I flash it in Clockworkmod or do both work? Also I noticed that there are different versions of this phone I am guessing for different carriers. I have SGHt-989 so are all ropms okay for all the model or are they model specific? It seems that the 9100 is the most popular model. I am sorry for all the questions but as soon as I am comfortable with this device I can start to understand it.
Thanks alot
Charlie

Rom manager only does fake flashes. Only way to get cwm on our phone is via flashing a kernel that supports it.
Download mode can be used for first time rooting (to flash kernels), also for flashing roms via odin.
Once you're rooted, with a cwm supported kernel, you can use the clockwork recovery to flash roms, or even kernels. This way, it deosn't increase your binary counter.
i9100 is more popular because it is the international model and most common.
I know it's been adressed many times in different ways, but the info I found yet is not clear so I need a little help! I am trying to install the latest stable Cyanogen mod, using Gingerbread 2.3.7.
I have a Galaxy SII from Bell that I rooted and unlocked when I got it last november. It came on 2.3.3 and I flashed an official 2.3.4 on it, mainly to improve the battery life (and it worked). I did that using Odin and it went well.
Now I try to install Cyanogen mod through ClockworkMod ROM manager, I download and launch the install from ROM manager but on restart the install fails because of the classic 3E recovery message that says the whole signature cannot be verified.
I was having doubts if my phone was even rooted, but since it is still unlocked and software like Titanium backup runs fine, I guess that confirms it!! I am not sure what route to take from here...
Right now here are the phone details...
GT-i9100 on 2.3.4, FW I9100XXKG2, Kernet 2.6.35.7-I9100XXKG2-CL375027 [email protected] #2
I'll appreciate any help!!!!!!

Thanks jje... The instructions did work! Tough I tought I had bricked my phone at one point, on the final restart it would get stuck at the Samsung logon screen, but I forced it back in recovery, re-flashed from the zip and then it booted in CyanogenMod!!!
I really appreciate your reply
Hey everyone,
i've got an i9300 device with 4.1.1 (XXDLIH) on it
I wanted to installed a custom rom on it (Omega ROM v38)
First i flashed CWM via Odin like in the instructions, after that i downloaded the rom put it in the sd card and booted the phone into CWM, i did the wipe and factory reset and choosed the rom zip for installing
After about 10 minutes the phone rebooted, but it is still on stock rom, so i thought what could the problem be and remembered that i need to root the phone first.
Now i have the problem that i can't (don't know), i don't know which way i should use for rooting so that i can afterwards install the Omega Custom rom ....
Note that i have now the CWM 5.5 recovery and don't know how to get back to stock recovery ...
Please if someone could tell me exactly what should i do, how exactly to root it and install the rom :/
Thanks everyone in advance
If you think that it would be better to install another custom rom then feel free to tell me

First the specs. Samsung Galaxy s2 GT-9100 running Android 4.1.2 Build XWLSH Kernal 3.0.31-889555
Need a touch of help here. Finally had the nerve to root the GS2 on the weekend and clean out all the crud not required... so far so good
Had no success in attempts to install CWM Recovery through ROM Manager (Recovery setup > ClockworkMod Recovery > Galaxy S2 i9100 > "does not have an officially supported...."). Also found the Recovery builds on the official site but no guides whatsoever as to how to install... oh so helpful
Finally came across a guide at galaxys2root[dot]com on installing recovery from download mode using Odin. Ran through the process and ended up stuck at boot with no way of proceeding. After a panic session, was able to recover from back-up (thank god I backed up the ROM and all data before attempting to install CWM recovery). Now I'm right back where I started with no idea how to go replacing the stock recovery.
Can someone please shine some light on the situation? At a complete loss as to how to get the CWM Recovery on the phone without bricking it.
Cheers in advance
1) Don't use Rom Manager. At all. Uninstall it. It will break recovery & cause bootloop eventually if you continue to use it.
2) Thread stickied near the top of Q&A has all the info you need. Essentially, any CWM you flash independent of the kernel will only persist until the next reboot. Reason being recovery is baked into the kernel on the S2 & isn't a separate partition like other phones. So you flash a custom kernel, you end up with rooted phone + permanent CWM.

A huge thankyou for pointing me in the right direction. I had since the original post found Mobile Odin (invested in the pro version) and installed the CWM Recovery from the their site... only for it to revert back to stock recover screen At least now I know why.
After much hunting around - I notice the stickied posts don't make it easy to find the correct kernel for for the AU i9100 - I found the PhilZ cmw6 kernel build.... used Mobile Odin to flash and all is now rosy.
Now question.... I was under the impression that ROM Manager was required as an install with CWM. I use Online Nandroid Backup to create full ROM/Data backups and trying out Nandroid Manager for selective recovery.... is that all I need then now that CWM is successfully installed in recovery?
Cheers again
Can't speak to those products as I've never used them, but Rom Manager & the S2 is a big no no. Doing nandroid backups, which is essentially a 'snapshot' of your phone at the time you make it, by simply booting into CWRecovery & also backing up apps/app settings with Titanium has always done the job for me.
Hi All,
Had my S3 for ever a year now all rooted succesffully and runnung wanamlite roms. all of a sudden it died - Samsung fixed it and my and sent it back however it was now on 4.3.
The problem I have now is that I am not able to boot any custom rom - I just get stuck at the samsung Galaxy GT-I9300 screen.,
Root Phone and install CWM
Check with Root Checker and its successful
installed all types of rom including Wanam 4.3 to no avail
All Stock roms including 4.1.4 work
I'm a bit stumped and any help would be appreciated - its as if my bootloader is locked
Thanks,
Jag
Die you try formatting everything including internal sdcard?
Do you have an international SIII without a simlock? Or was your SIII shipped with a simlock in the first place?
If you have a verzion SIII try this:

Ive done a clean rom install through philz cwm - im assuming this is the same as a clean install?
Im based in the uk so doubt I have a verizon model.
Thanks
You say any that presumes you have tried them all .
In recovery format sdcard system data cache boot to download mode flash stock rom or boot to recovery and flash your custom rom .
Really you should start by reading the faqs and guides first .
Hi,
Sorry for being so brief.
I have formatted sd card through mounts and storage and cache
Done a clean ROM wipe also.
Still no custom rom appears to boot - all stock roms flash fine through Odin. Restores of stock ROM are also working fine..
Then you are doing something wrong .
Start with a stock cwm rom .
