I just rooted, I've got ROM Manager and I'm about to use it to install the ClockworkMod recovery.
If I ever decide I don't want it, can I restore the phone's factory recovery console? If so, how? And will the method vary as kernels, firmwares etc do?
Thank you.
As much as I know, ROM Manager does not work on SGS2. Please search for the "CWM" thread in the "original development" forum.

Then I wonder how I am to perform the same kinds of activities ROM Manager supports, like installing and backing up ROMs. Is there a GUI-based alternative?
Im also some what new at thia stuff.
First you should get your hands on the program called ODIN and also the cf root that matchs your current phones verison.
Thay way when you flash your phone tou get clockwork mod and then back it up.
I am sure others can get into more detail but as i said.... I am also new at using ROMS

First stop posting your questions in the dev sections, second you don't need rom manager to do all that, you simply need a to flash a kernel that has cwm recovery built in, that's what rom manager boots into anyway.

Just moved from iPhone to i777, wanted to get ICS, but eneded up bricking my first phone by installing something meant for i9000. At that time I didn’t know Galaxy S2 has variants, just searched for S2 and got burned. My fault…..should have understood better.
I want to do it right this time so I have been reading about i777, ROMs, kernels, CWM.
I want to put SHOStock or CM9 ROM.
I know where these ROMs are and how to flash them using CWM.
But that’s where my confusion starts, that there are just too many sources and options and I don’t know which one is right.
So please advise.
How do I root?
Using this? It has multiple options
http://forum.xda-developers.com/showthread.php?p=18576627#post18576627
or this ?

Which kernel to use
The one mentioned in SHOStock thread #3 post the Cherry Picker Kernel for i777 or Entorpy? Siayh
How do I get CWM on these, isn’t recovery part of the kernel or do I flash It separately or may be use ROM Manager, once rooted.
Modem? What does it do? Is it for phone or wi-fi and how do I know which one to use.
My phone’s data
SGH-i777
Android 2.3.6
Baseband I777UCKK6
Kernel 2.6.35.7

GINGERBREAD.UCKK6
Here's what you need to do:
1. Use Odin to flash stock UCKH7 with Root, available here. Be aware that doing this will require a full wipe, so do what you can to back up your sms/mms/contacts and other data. READ EVERY STEP CAREFULLY. Do not flash a kernel with Odin.
2. Now that you have root access, download Mobile Odin from the Play Store. Use it to flash either Entropy's DD or Siyah. This will install CWM Recovery.
3. Boot into CWM Recovery and make a nandroid backup.
4. Use CWM to flash SHOStock or CM9.
First of all thanks for responding.......
Is there a relation between which ROM will work with which Kernel, I may be wrong but I got the impression, depending on which ROM you are putting, you should have a kernel that supports it.
Also it seems like, ShoStock has its own variation of entropy, named cherry picker.
Thanks.......

Sometimes there is, but it seems like most of the ICS kernels are interchangeable. Just try out each kernel for a few days...once you have CWM, switching kernels is no big deal. When switching kernels, though, it's always wise to flash jivy's Kernel Cleaning Script just before flashing a new kernel.
Can you use CWM to flash kernels as well ? I thought they always have to be done using ODIN.
May be I underestimated CWM, I thought it was for ROMs and zips only.

u can use mobile odin or cwm but its just a matter of preference you just had to use mobile odin at first to acquire a cwm enabled kernel but pretty much you can flash everything in cwm as long as its specified to be cwm flashable zip kernels roms and modems and such
edit: the free mobile odin only lets you flash kernels btw its the premium version that lets you do everything without going to recovery
hope to help

You don't seem to have a firm grasp on all this. Maybe you should do some more reading before going further...
Anyway, here's a brief explanation:
A kernel is the underlying core of the operating system; it is how the OS interacts with the hardware.
A rom (the proper term is actually firmware, but nobody uses it) is basically the whole user interface; it's the part of the OS you see. When you flash a rom, you're flashing everything, including a kernel.
Like I said before, you never want to flash a custom kernel using Odin. Doing so will trip the phone's flash counter, and this will show up if you ever have to take the phone in for warranty stuff.
The reason it's ok to use Odin to flash the stock with root package is that it comes with the stock kernel, not a custom one. Basically, once you're rooted, you shouldn't touch Odin again unless its to recover from a brick. Basically everything else can be done in CWM.
Yes I am still reading & trying to get a grip on it.
So first I will root it, then flash kernel using Mobil Odin
Then get in CWM mode ad flash ROM, which will come with the kernel i.e. cherrypicker kernel and modem I need.
Yes one part I have understood very well is that use CWM as much as one can to avoid committing mistakes by flashing something that doesn't belong.
Sorry for asking so many qs., I wish I could understand this faster.....
Thanks again........

You don't need any more of a guide than that. Don't worry about breaking wifi, that isn't a problem on any of the popular roms.
If you want a Samsung based ICS rom that works really well, I suggest ShoStock2. If you want an AOSP based rom, most people suggest AOKP. I haven't tried it personally.

Full root box AOKP? I'm not sure what that is...just flash the entire AOKP ROM. It will flash over the i9100 Fluxii, then you can download and flash the correct version.
I downloaded the root box aokp rom which is what I thought was the i777 version. I'll re-download this version when I get back home.
Sent from my SGH-I897 using XDA
Are you talking about Task's AOKP? http://forum.xda-developers.com/showthread.php?t=1574718 If so, just reflash it in recovery. Reflashing AOKP uses Task's CM9 kernel and it'll overwrite the i9100 version of Fluxii you installed.
reflashed aokp rom. now im getting numerous process errors. android keyboard has stopped working, rom control has stopped, process.android.phone has stopped. have went into CWM recovery and re-installed zip and wiped davlik data, partition data. only other thing i havent done is factory reset. i even unrooted and re-rooted to get it back. now im getting the i-9100 boot logo with the yellow triangle.
Yikes. Did you happen to make a Nandroid before flashing? If not, you may have to return to stock. You also might want to get on IRC and try to get someone to help you real-time.
i just connected it to my computer, removed the other roms that i had and some other unneeded files, like the i9100 files, did a factory reset, re-installed the rom from recovery, reinstalled gapps. so far i havent gotten any process errors. still have the i9100 boot icon but i can fix that with the triangle away from the market. sucks that rootbox isnt going to be made for i777, i checked the thread and bajee confirmed he's only doing it for the i9100 or the s3. so im s.o.l on that. is there a way to get the fluxi kernel though? or is it stuck with whatever rom ur using?

Um, how about going to the fluxi thread, downloading it, and flashing it? If you don't know this stuff, you shouldn't be flashing anything at all.

You did ask a very simple question. And the very simple answer to your very simple question is readily available in the forum stickies.
If you think flashing kernels an flashing roms are completely separate processes, you don't understand as much as you think you do. Did you know that every time you flash a rom, you flash a kernel too?
And no, I don't know everything. But having knowledge isn't the key...the key is knowing how to acquire the knowledge you need.

You have to have a rooted phone to flash kernels. The Cubed kernel is a modified kernel for root users that gives you the ability to overclock your phone, better battery life and such. It is not the one that came with the DNA, the DNA is the stock kernel from the factory. Don't go by the numbers you see because they are 2 totally different kernels for totally different reasons...

This is the stock kernel but just modified to be able to write to the system while booted. It basically is the stock kernel and will work exactly like the stock kernel does. To switch kernels, just do what you did before when you installed the kernel you're on now. Just make sure you flash the correct module zip in recovery after you flash it.

I would try a fresh install of the ROM you're currently on, including a fresh install of all your apps. See if the problems persist and report back if they do.
I'd also check the development thread for whatever ROM you're on and see if any other users have experienced issues such as yours.
