I am a little new to rooting, I rooted my galaxy 2 yesterday and I tried to install from manager and it's not compatible with my device. I was reading threads and saw that it is better to boor into recovery mode and flash a rom. I am hesitant to do it because I don't know how. I read but still cautious. So can someone give me a little clarity on this subject. Also is there another app that I could install similar to mod recovery... and do I actually need it.... what apps are mandatory to have.. where can I learn recovery so I don't have to use mod recovery?

Hi, I have the I9100 from two weeks, and I had noticed that samsung phone architecture is slightly different from other android phones.
Before I9100, I had an HTC MAGIC, HTC HERO, NEXUS ONE, ZTE BLADE.. all of these phones are managed and structured in the same way: Bootloader, Recovery, and ROM.
When I get the root, I can flash the recovery, and then I'm sure that if I flash a buggy rom (with a buggy kernel) I can always start the recovery and flash another one.
In samsung is different and I can't find a technical guide on how this phone works.
It seems that the recovery is INSIDE the kernel. Then if I flash a buggy kernel I loose the recovery!
Another strange thing... why do I need to use odin? And why some of the roms (also here in xda) must be installed trough it and others trough recovery?
Why some people have flashed a buggy kernel and can't flash trough odin?
What's the download mode is used for?
Is download mode is a state of the phone that is loaded before and without the kernel?
Why I can't use rom manager (installed trough the market) to flash my recovery and I need to use the CWM that is hardcoded inside the kernel?
I need some answers because I don't wanna follow the guide without knowing what I am do.
Can someone help me?
... no one answered me yet?
Are my questions, silly questions?
I looked into the guides I found here and I didn't found any answer for me..
Well I Don't own a s2 but samsung androids are different
There is no separate recovery partition so it needs to be in the kernel/rom
So its obvious an other method is needed to flash roms if something bad happens with the current rom/kernel so odin and download mode exist
Very Interesting... but.. is download mode loaded before (ad instead) kernel?
If this it is a restore operation should be loaded always.. also from a complete wipe of everything right?
But.. I read somewhere that some buggy kernel does not allow odin to find the phone..
Then.. If I lose the recovery and odin does not recognize my phone... Am I in a 'deadlock' situation?
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
To root your T-mobile SGS2, watch this video

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.
Ok guys heres the deal....i recently got a samsung fascinate from my sister cause I couldnt mod my inc any more. ok so....i got the phone rooted. i have su perm. i downloaded rom manager and installed it. now heres my problem. i can preform a backup no problem, but when i go to restore that backup it boots into clockwordmod and begins and then get an error about erasing boot img. or something like that. can tell exactly if i get some help from this. also cant install custom roms like i can with my incredible. i know it can be done cause i see roms and all for this phone. can someone please please help me.
Thats because cwm3 will not perform nandroid restores on stock roms. You need to flash cwm 2.5.1.x red recovery. Its the best recovery imo for any bml(touchwiz) rom. Go over to my guide in general section and you cand find cwm 2.5 in section 2&5. Oh and ditch rom manager...manually install cwm via odin!
If you're coming from an incredible, also keep in mind you don't have to be rooted to flash roms either, you just have to have a custom recovery. There aren't really any modifications like rooting procedures, S-OFF, etc, required for rom flashing, just odin a recovery and flash your selected rom.
Hello dear community
This is my very first thread I am making on this website, so please pardon me if I am on the wrong page of this website.
Anyways, I'm more or less desperate. I saw a youtube tutorial on how to install Android 4.4 Kit Kat on a Samsung Galaxy Note N7000 and I heard I'd need root AND a custom recovery.
Because I'm a total newbie to this kind of stuff, I tried the very first thing I saw that had something to do with custom recovery, because I already had my phone rooted. So, I looked up a tutorial on youtube on how to install CWM custom recovery and ended up with installing it successfully, but now my phone is stuck in a bootloop. As I already mentioned, I am a newbie and therefore I am very desperate at the moment, you know.
The only thing I can do is go to Recovery Mode, but if I try to turn the phone on it gets stuck in a bootloop (It actually doesn't loop at all, it just freezes at the moment when the Samsung Galaxy Note logo appears and doesnt do anything after that.).
I think my problem is that I actually threw a new Kernel on my phone, because the video title says "How to install Kernel with CWM [...]"
I would be very very very very very grateful if anyone was kind enough to help me get out of this!
I really need help!
Thanks!
PS.
If this helps you help me:
This happened when I had Android 4.1.2 installed.
There's going to be 2 ways to get out of this:
1) Reinstall the stock firmware via Odin.
2) Install a custom rom via recovery.
Personally, I'd go with number 2 because a) you wanted to update anyway and b) if you have the right recovery and rom, it'll be easier as you can just put the files you need on an external SD card and install via the custom recovery. Now, not all recoveries are able to flash any file. Many times you need specific ones to install the newer android versions. So, if you are wanting to install something 4.4 based, then using a recovery that was made, say, last year, probably will not work well if at all.
Another thing to try first, is to wipe the cache and dalvik cache in recovery since you said you tried to install a kernel. It is always recommended to wipe these when installing (assuming you did pick a compatible kernel with what you were trying to install).
Hi i want just install cwm on my s3, and be with stock firmware , i dont wanna install Custom Roms or same like that, just be with CWM and stock rom. so still root required when CWM INSTALLED FROM ODIN? SORRY FOR DUMP QUESTION
No need to root before installing a custom recovery with Odin.
I recommend TWRP over CWM as CWM has not been updated for a very long time.

Neither has the s3 and twrp is known for borking your nand, so much so that they have a section on it on twrp website.
My opinion, use the last official cwmr for your device.
@shivadow, I didn't know that twrp affected the s3. The last version I recall using on the last few sgh-i747m phones I had was 2.87.
Do you have a link to the twrp section regarding this issue? Might be good to have it stickied?
Thank you.
Twrp buggers all devices in the end, not just the s3. It's like there's a bug that can't be solved.
