Hi guys, I'm a french speaking swiss personn ^^
I'm using the SGS2 since aboutly 4 months now and I get it rooted in early june...
But I'm experimenting random reboot, a few, not often, but sometimes... usually when getting superuser autorisation and often when starting and analysing SD card !!!
I don't know if that are know issues, but I thing an update would be anyway really good for my phone.
BUT !!!
But there is a problem : I don't want to loose anything I already have on it... I bought a few apps, installed a lots of things... Some of which aren't in the market anymore (!!)
And I sync a lot, really a lot, email adresses, gmail account, etc. ^^'
I have 14 Gmail accounts, 4 email adresses and some things like skype, ebbudy, facebook and I really don't want to have to re-sync everything, re-type my passwords, etc.
So, what should I do ???
I have for the moment :
GT-I91000
2.3.3
I91000XXKDJ
2.6.35.7-I9100XWKE2-CL187606
[email protected] #2
GINGERBREAD.XWKE2
Is it really outdated ???
I have to say that I really love Touchwiz, so I absolutely want to continue using it, and I don't want any data loss... Contacts, bookmarks, etc. ^^'
Is it possible to update or upgrade to some new kernel/rom/android version ???
I don't care about using Odin, I know it, played a lot around with it and my Adam Tab
What is really brand new ? I'm really not up to date with android news, so I don't even know if 2.3.4 is already out or what ever, maybe there is Touchwiz 5 also ? ^^'
So I come here hoping there will be some generous person wanting to share its knowledge with me
Oh, and obviously I need to have root (Titanium backup, Chainfire 3D pro, etc.)
And it has to be in French (I mean the OS).
So, anybody ???
Ho, and btw : how could I make a full backup of my phone, so that if anything goes wrong I would be able to come back to the state it is now, with all SMS, all whatsapp, all email all aps, all settings saved ???
BTW 2 : I though a little about that whole : is there any easy way to get my apps, my save, etc. and to put it in a new rom after a full wipe, etc
And with the less data-loss as possible ???
I mean, it's ok if I loose some small things, but all the apps I have and my email/gmail account are the only really important things... I could accept to loose my SMS, my angry bird savegame, etc. It's no vital matter
PS : I know I could work this out myself, but it would involve hours of reading, blogs, news, etc. And then I should search the whole forum to find the really relevant topics and only then I could maybe update my phone... I know it's like that, because I did it once in june to root my phone, there wasn't lots of methods but there was loads of topics saying somebody did maybe see something that looks like a one click root and then another topic claiming there isn't any one click root for the moment but that this method was fine, etc etc etc !!! Eventually I used the chainfire methods... I hope it won't cause any problem...
So, I'm having no time to get through the floods of informations there are out there on the net, that's why I dare ask such a thing
Uh, really nobody as any clue to give?

If you want to keep touchwiz, I would definitely suggest Cognition Rom. It gives much better speed and battery life and also gives great new features.
http://forum.xda-developers.com/showthread.php?t=1124396
However to install it you need to wipe your phone.
If you sync all your contacts, calendar etc. with Google and backup up all of your apps and app data with Titanium Backup you will not lose anything.
If you ever feel like moving away from touchwiz, try MIUI.
It has speed, better battery life and nicer aesthetics.
Wow...long post.
So, to recap:
-You're getting random reboots.
-You want to flash a new ROM that has TouchWiz and Android 2.3.4
-You don't want to lose data
1. Nobody can tell you which ROM to use. Go to the dev section and pick one based on the description and your needs.
2. You need Titanium Backup Pro. This will backup all your data.
On a side note, I would suggest that you only restore your user apps and not your system data. If you restore you system data, there's a chance that you'll simply recreate your reboot problem on your new ROM. But doing so means you have to type in your login details for all your stuff again. But I suppose that's the price you need to pay. No free lunch in this world.
And what about lighting rom ?
Has it touchwiz ?
uh and I don't want especially android 2.3.4, I just want the latest one, so if 2.3.6 is out I would like to get it ;D
But it certainly not the case.
Why do you prefer custom rom to stock rom from samsung?
Where could I find a real review of those custom rom ??? with explanation, what did change from the stock rom, how good the battery life it's improved, etc... ?
I have two days battery life if I don't play games... And I manage to get up to 3 days 20h once, without plane mode ! Will it be really better?
Thanks
PS : sorry for the length of my previous post, I'm not good at shortening stories ^^'
PPS : I remember something called CWM came with the root, is that usefull, or not in my case ? I think it's a backup utility, isn't it ?

Start by reading the rom description Touchwiz is standard unless otherwise stated

KH3 latest 2.3.4

By reading the rom posts or by trying the roms .

No thats very good battery life

And I still have some questions :
to which extent will I keep the apps I installed, and the data I have on my phone when flashing a new one ??
Titanium Backup will backup what ?
And where is the global backup option ? There isn't any I think...
Do I have to clique on each apps and then click on "save !" etc. for every of them ?
And then flash the new rom, etc. and won't loose any apps ?
And how could I do a full backup of every think on my phone to my computer ???
I have only a few space left on my phone... 1GB aboutly... Well, lot of it is just files I put on it, music, videos, etc. But I guess some of it are coming from my apps...
Do a full wipe and flash new rom won't delete of those any data ???
And then with my new rom, I just have to install Titanium Backup pro and it will see every saves I did and I will be able to restore them ??
I guess I'm quite a noob with that, because I played a lot around with my Adam, but I never care about keeping any data in it...
That the first time I worry about data loss and ROM and android
PS : thanks a lot for that link, I don't know how I was able to miss this huide ^^' But it doesn't answer all my questions ^^''

Keep all if its a no wipe keep none if its a wipe .

APPS

TITANIUM PRO its batch

Not possible ?

Yes if its a wipe it may so backup your files and data .

Yes but wise to backup your Titanium backup folder to PC as a safe copy .

Okay...
Well, for titanium backup... I still have a problem : how could I use this "batch" you mentioned... ??? I know batch as being files you use on the computer to run some scripts... from killing process and starting others to connecting to network or printer or whatever you want...
But I don't know how to use Batch with android...
So, I just read about Nandroid backup... Can I do one with my phone ?
I have the CWM Manager v1.80 on it, from my root... What is this "backup" function it has ? Nandroid backup ? Do I need lot of space on my SD card to do it ???
And then could you advise me about all those ROM there are out there ???
My questions about them :
-If I want a stock ROM from samsung but the latest one, what should I install ?
-If I want Touchwiz (the latest), gmail, email, calender, sms from samsung, but that I would like to have something more optimised, what should I look for ?
I would actually like to get a samsung Rom, with the latest update but deodexed, "zipaligned", well optimised in a word... Camera hack would be nice, but not necessary, I can do it myself, as I already did...
In a word I want something efficient : simple, fast and functional...
If it has cool features like the lock screen personalisation, etc. I don't say no, but if it's not smoother, faster, "better" than the samsung stock rom with the Chainfire CF-Root Kernel, then it doesn't interest me ^^'''
Thanks for your patience, I know I ask lot of stupid questions.

Again you got to read the custom rom posts and make up your own mind .
Root wont make a rom faster .
Personally you should stick to stock until you know what you want and find the rom with your needs .Their is not the room to improve SGS2 as with SGS1 .

WIPE WIPE WIPE !
+ Cognition Rom
Ok ok...
What are the main differences between Cognition and Lighting ???
There really aren't review so it's quite hard to find out ^^'
I would like to get something who looks quite like the stock rom... with touchwiz...
And what about the CF-Root ??? Does the kernel of Chainfire work with Lighting ? or with Cognition ??

Plenty of roms to choose from, I've tried the majority of them but prefer the stock like ones such as VillainRom or Modaco Custom Rom. Both are very good. Leos rom is also good with his kitchen. Just read through the threads and you'll get an idea of what they are like.

Alright, I messed up my phone trying to backup it '^^
So now I've installed Lighting 6.1 ... But I find it less reactiv as what I had before... Is that strange or not ?
Also : what do you mean with "stock ones like VillainRom or Modaco Custom Rom" ???
You mean it's just like stock from samsung ? But there are certainly differencies, aren't there ? Where are those diff ??
And still a question : for smoothness, reactivness and confort of use, what will be most important : a good ROM or a good Kernel ??
Because there are lots of kernel also, is that a better idea to get a stock rom, a firmware from samsung, then to wipe everything and to install it and then flash another kernel ?
I just want a little better perf and battery life, I don't care about features or whatever : the samsung touchwiz feature are fine for me...
I just want root also. (for some apps)

VR and MCR are like stock roms with tweaks to make them perform better. Other roms add like camera mods, themes, and other type of tweaks to them as one package. The 2 mentioned VR you have VR tweaks to customize as you like, and MCR has an online kitchen to customize as you like, as well as Leomars rom has a kitchen to install additional tweaks. I prefer these so I can tweak as I like.
Kernels you have to try them all and find the best combination. I like speedmod and ninpos kernel,both are great. Both are fast and smooth as well.

And what about Touch-X I just saw the topic about it a few moment ago ?
About kitchen : how does it work ? is that on the phone directly or on the computer ? It's kind of an app ??
try leomar 2.6--best rom and support ever
Guys
Can someone point me out to a stable and fully functional MIUI rom for galaxy s2 ? . I could not find any info regarding the rom on MIUIs website as well
I use Galnet Miui (galnetmiui.co.uk) 2.11.26 and have had minimal problems.
Now...
Just because it works well for me does not mean you will have the same experience with this rom. Your phone will have been built ever so slightly differently to mine so far as the "quality" of the components go, you will have different apps installed on your phone and you will have different usage patterns to me.
So what I'm saying is by all means try it out, but also try out other roms & see how they work for you.
I find it impossible to believe you went to Miui.com, clicked on the english site & couldn't find the downloads. That tells me you didn't try hard enough, so I suggest you go back there and have a proper look. Also, you can have a look at Miui US, their rom is a different take on Miui again.
If you're not the sort of person who's prepared to do a bit of searching and experimenting with your phone, and you want a rom that's always stable , I suggest you leave your phone on stock firmware & just enjoy a fantastic phone (the phone is brilliant just running stock).
Thanks mate for the detailed reply . I did find the download section ! , however i did not find any help on its forums regarding the quality of the ROM ( what is working and whats not ) . And i still cannot find it
And i can search and experiment . Running CheckRom V4 for a while now and its pretty nice !
"Quality" is a subjective thing. It gets back to what I was saying about different people having different experiences with different roms.
So far as what works & what doesn't, there should be a changelog with every version of the rom, I know there is for Galnet's roms and I'd be very surprised if there's not for Miui's roms (which means I'm not going to do the searching for you).
I installed the miui.us rom . Apparently everything is working . Just the video in 720 or 1080 is not working !
is that working in the Galnet`s rom ? you can atleast tell me that

Miui.us? May i know which version you installed?
Rom : MIUI ICS XGT 'EXTENDED'
Kernel : Xcell-69X
Modem : XXKP8
Sent from Galaxy SII
It was 1.12.30
But i am back to CheckRom . Was having a few problems with the Rom
* SMS app was giving constant FC ( even after trying the fix )
* Camera app was closing randomly without any errors etc
* Phone was running too Hot
* Quadrant score went down from 3600 to 2800 ( not bothered that much with that )
Just for you (because I've come to like you somewhat during the time this thread has been in existence), I tested 1080HD video just now and it works quite fine.

Do you mean that all roms here are not always stable?
Yep that's exactly what I mean. It's pretty rare to run a custom rom and not have any issues (mostly minor issues tho, mind you) at all. So many different apps, some of which work perfectly with some roms/kernels yet are nothing but trouble with others.
Stock has had the absolute living crap tested out of it by Samsung and if you want (almost) absolute stability with almost no problems whatsoever, then stock is what you want to run on your phone. On the other hand, if you're spending time on a site like this chances are stock just isn't your thing and you're more than prepared to put up with little issues that come up occasionally running a custom rom/kernel.
I know I am. I can't see any reason why I'd ever go back to stock, I can't think of a "gamechanger" or feature Samsung could put in a stock rom that couldn't be made to work in a custom rom by the *really* talented devs who post here that would make me go back to stock.

Hello everyone.
It has been a long time since I was here looking at things.
I'd like to say that there is great progress and Kutos to those who are doing the work.
-------------------------------------------
Anyone have any good/bad experiences using the kernel I listed below?
And, I do not really want to overclock at the moment, Is there a way to edit the kernel to remove the changed CPU and battery management?
I tried to find a custom kernel that, without all these extra changes, allows a custom ROM, but I have had no luck yet...
(I do not want to shorten the life of my device in any way); unless it is safe?
------------------------------------------
I was thinking of using this kernel (which I want to put the unnecessary changes back to stock):
[KERNEL][CWM][Player 5.0][USA]Entropy's Daily Driver, 3/5/2012 (1.2 GHz OC)
-------------------------------------------
And I'm still deciding between these two roms:
1) [ROM] Eryigit-GB-2.3.6 G70ZCKPA Galaxy Player 5.0 For USA and INT (Rls:3.5) {UPDATED}
2) [ROM] Eryigit-GB-2.3.6 G70XXKPH Galaxy Player 5.0 For USA and INTERNATIONAL (Rls:1.5)
My problem is I do not really understand the differences between these rom versions other than the display.
Is that all that is different? the themes?
And I'm having trouble finding if this ROM can actually work the cameras, flash, Bluetooth, etc. or are things not working?
I tried looking for a "bugs" category, but I haven't seen one.
----------------------------------------------
Thank you for posting your experiences and such.
I'd jump right in and try the kernel and roms, but I really do not want to risk breaking anything, I kinda just want to do it right the first time and leave it.
--------------------------------------------
I mainly been looking because I read that Samsung is not planning any updates for my device and I figure I'd modify it now since I wont get the latest android for it.
My device:
Samsung Galaxy Player 5.0 Wifi USA version, WITHOUT mechanical home button...
You cant edit the kernel and off course its safe,everybodu is using them..but if you want you can down clock with some app but don't see why..on roms you mentioned everything works...difference is first has more futures like 14 button power menu etc..and second is basicy stock rom.
Alright bro. Entropy Kernel: You wont notice anything different in your Player if you flash it. It will only make it faster, but no UI changes. And the ROM you listed, use 3.5, Everything works. Again, more tweaks will make it faster. The ROM probably has some things changed in the UI but thats for the better. No bugs in that ROM. If you need help don't hesitate to PM me

Sorry I have been away for a while. College takes up all my time...lol
Thank you both for posting that. It verified everything I needed to know about the ROM and Kernel.
(I just want this to last if I overclock it with with the custom things, I do not feel like replacing a battery within the next couple years...lol).
Later on I will go find an odin or something along those lines and backup what I can from my device so I can hopefully go back to stock later if I ever needed to...
Hopefully I will be able to do it before the world ends in about 3 months. I will post here when I get to it.
I just recently bought a 32 GB MicroSD card for it. Its really nice as I can store everything in my phone now and its essentially my slate PC but its a phone, so I will need a time when I wont need to use it for school/work/navigation things for a while so I know its stable.
Hi,
I am a new Galaxy S II (i9100) owner. I have a couple of questions, if some of the experienced users could please assist me I would greatly appreciate it. My questions are listed by priority:
EDIT: I am rephrasing my questions and putting the answers that I feel are best suited so that people who are interested can see the answers in one clean post
1) I understand that CM Mod is based on AOSP and is used as a base on a lot of ROMS but could someone please explain to me how a ROM could be an AOKP ROM and "Based on CM10". Are they taking certain modules from CM10 and certain things from an AOKP Build and putting it together?
ROMS usually take the best of CM and AOKP and combine to produce a more stable base.
2) I know what CWM is but once you use ODIN to flash CWM onto your phone where does it go? By this I mean, does it sit on the ROM or somewhere on your Internal SD card (or both, maybe it puts settings on your SD card). I would like to know if I format my Internal memory will it remove or cause CWM to bug out?
CWM will get removed from your phone if you flash a Kernal that doesn't have CWM on it. It will also get removed from your phone if you "format" the internal SD as that is where it is stored. CWM will NOT be removed if you flash a update to your phone that doesn't require you to "wipe"
3) I am not a fan of the Stock Samsung ROMS because of the bloatware that it contains. However, is it all possible that these Stock Samsung ROMS have built in optimization code or something that works better for my specific device? I ask this because the best battery life I've managed to get was on Stock Samsung ICS where as my battery life dies on any of the JB Roms (Even SlimBean)
AFAIK Stock Roms are optimized for basic / standard features. Custom ROM's can be optimized for the way you use your phone. A Stock ROM is a "One Size Fits all ROM" a Custom ROM can be "Tailored" to fit your needs.
4) I understand how I/O Schedulers / Governors etc work but what advantage does using a non stock Kernel have? As far as I understand these can be changed on any rooted Kernel or am I incorrect?
I/O Schedulers / Governors can be changed on rooted or non rooted Kernels. Rooted Kernels have access to their own custom schedulers and governors.
5) When I download an app from Play store is there no way for me to not install it and just download the APK? So that I don't have to backup all my apps (I don't like using Titanium very much) and so that I can just reinstall the APK files from my internal Memory?
No There is no way to get around this. Install APK files from the Web. Use Titanium Backup to backup applications installed from the Play Store.
6) I've followed the guide to enable or disable Fast Dormancy (I'm still learning about this) however when I type the code in my phone (*#9900#) or (*#0011#) nothing happens. Is this because I'm running JB and these codes only work on ICS?
These codes only work on Stock ROMS
7) When I have a look at my battery usage (currently on CM10) screen says "52%" even though my brightness is set to like 25%. I am trying to figure out why my battery is dying so fast. Is this normal?
There is no "Normal". Too many factors involved. Have a look at the BBS Thread http://forum.xda-developers.com/show....php?t=1179809. You may post your BBS dump/log in this thread and ask the experts to analyze it for you.
8) What is the main difference between AOSP and AOKP? I understand that AOKP will open up a lot of other customizations to me but what are these customizations? I assumed it was things like setting the governor and the I/O Scheduler etc but I've installed ROMS based on AOSP that allows me to do that.
Busy Formulating an answer
9) Galaxy S2 Modems I keep flashing different modems on my phone but I see no change in signal whatsoever is there an application or anything that can help me get an accurate benchmark so that I know which modem is "best" for me?
This is usually done by trial and error. Have a look at the Modem / RILS thread to ensure that your Baseband and RIL version match. Alternatively you can use an app called GETRIL which will get the correct RIL file for your modem
10) Please don't mistake this as a "What's the best ROM??" question. I've tried many different ROMs and I still haven't got a favorite I am looking for someone who has an idea of which ROM will mostly fulfill my requirements which are:
(BTW I'm leaning towards SlimBean here)
1) JB (I love JB keyboard)
2) Battery life (I think I'm looking for something that uses the conservative governor)
3) I mainly use my phone for WhatsApp (I use this ALOT) and browsing (barely for games)
4) Lightweight (I don't want Samsung Apps, I don't want a ROM that has 3 launchers etc.)
5) I don't mind charging my phone once every 16-18 hours.
6) Preferably AOKP so I can mess around and experiment and perhaps give back to the community
This is my personal opinion but I think that SlimBean will best fit my requirements

Ha ha, next time, please don't post so many questions in one post.
Then you will get more answers IMO.
I can't answer every question, but I'll try my best:
1) As I am using stock / Sammy ROMs only, I can give no clue to that. Please search and read a bit in ROM threads.
2) In SGS2 firmware, recovery (CWM is a special, enhanced recovery) is included in the kernel. If you format your internal memory (sd card), it will be removed, and will have to flash a new firmware (whole ROM including a new kernel with recovery) to your phone.
3) I like stock / Sammy ROMs, but custom ROMs may include same or similar device-specific drivers/etc. AFAIK.
4) Most custom kernels support different I/O Schedulers and CPU Governors. So you can switch to the one you like/prefer.
5) Apps from Play store will be automatically installed on your phone. That's why so many users are using Titanium Backup.
6) There is an app from gokhanmoral to switch Fast Dormancy on/off. I don't have the link, so you have to search for it here on xda. The USSD codes won't work on some ROMsm such as non-stock or JB.
7) Have a look at BBS thread => http://forum.xda-developers.com/showthread.php?t=1179809. You may post your BBS dump/log in this thread and ask the experts to analyze it for you.
8) Have already google it, or look at wikipeadia. I have no better answer ... sorry.
9) Have a look at the modem thread here => http://forum.xda-developers.com/showthread.php?t=1131950, and here for modem/RIL files => http://forum.xda-developers.com/showthread.php?t=1881304
10) No "What's the best ROM??" question?! Sounds like that to me You have to check different ROMs yourself and decide yourself what's best for you and your needs.
Good luck !

Hi,
I am a new Galaxy S II (i9100) owner. I have a couple of questions, if some of the experienced users could please assist me I would greatly appreciate it. My questions are listed by priority:
1) I understand that CM Mod is based on AOSP and is used as a base on a lot of ROMS but could someone please explain to me how a ROM could be an AOKP ROM and "Based on CM10". Are they taking certain modules from CM10 and certain things from an AOKP Build and putting it together?
2) I know what CWM is but once you use ODIN to flash CWM onto your phone where does it go? By this I mean, does it sit on the ROM or somewhere on your Internal SD card (or both, maybe it puts settings on your SD card). I would like to know if I format my Internal memory will it remove or cause CWM to bug out?
3) I am not a fan of the Stock Samsung ROMS because of the bloatware that it contains. However, is it all possible that these Stock Samsung ROMS have built in optimization code or something that works better for my specific device? I ask this because the best battery life I've managed to get was on Stock Samsung ICS where as my battery life dies on any of the JB Roms (Even SlimBean)
4) I understand how I/O Schedulers / Governors etc work but what advantage does using a non stock Kernel have? As far as I understand these can be changed on any rooted Kernel or am I incorrect?
5) When I download an app from Play store is there no way for me to not install it and just download the APK? So that I don't have to backup all my apps (I don't like using Titanium very much) and so that I can just reinstall the APK files from my internal Memory?
6) I've followed the guide to enable or disable Fast Dormancy (I'm still learning about this) however when I type the code in my phone (*#9900#) or (*#0011#) nothing happens. Is this because I'm running JB and these codes only work on ICS?
7) When I have a look at my battery usage (currently on CM10) screen says "52%" even though my brightness is set to like 25%. I am trying to figure out why my battery is dying so fast. Is this normal?
8) What is the main difference between AOSP and AOKP? I understand that AOKP will open up a lot of other customizations to me but what are these customizations? I assumed it was things like setting the governor and the I/O Scheduler etc but I've installed ROMS based on AOSP that allows me to do that.
9) Galaxy S2 Modems I keep flashing different modems on my phone but I see no change in signal whatsoever is there an application or anything that can help me get an accurate benchmark so that I know which modem is "best" for me?
10) Please don't mistake this as a "What's the best ROM??" question. I've tried many different ROMs and I still haven't got a favorite I am looking for someone who has an idea of which ROM will mostly fulfill my requirements which are:
(BTW I'm leaning towards SlimBean here)
1) JB (I love JB keyboard)
2) Battery life (I think I'm looking for something that uses the conservative governor)
3) I mainly use my phone for WhatsApp (I use this ALOT) and browsing (barely for games)
4) Lightweight (I don't want Samsung Apps, I don't want a ROM that has 3 launchers etc.)
5) I don't mind charging my phone once every 16-18 hours.
6) Preferably AOKP so I can mess around and experiment and perhaps give back to the community

1. Yes the best of cm and AOKP where combined to produce a more stable base.
2. CWM or clockworkmode is a phone based recovery that allows you to make changes without powering and rebooting the phone in recovery mode. It is added to rooted kernel and will disappear if you flash a wiped or standard kernal over it.
It will not disappear if you flash an non wipe update to your phone.
3. jb roms are getting better with the battery as new optimizations are being intergrated. Stock roms were designed around the battery with minimal features implemented, when you add apps your battery will start get worse.
4. yes they can be changed on rooted kernals or non rooted kernals. On rooted kernals it gives you more control over the functions of the phone.
5. unfortnately play store automatically installs the apks automatically. you need to back them up with a program similiar to titanium back up. They are a few different versions in play store just find one you like. Only non play store apps download the apk for you to install yourself. One of the functions of CWM is to allow you to install APKS. I System Tuner Pro myself.
6. Correct, those codes only work with the stock keyboard and ics roms as JB Have very little stock apps included.
7. How fast the batttery discharges depends on a number of factors like what apps are running, If you leave wi fi on and if you have wake locks. BBs which is a battery recording app can found on this forum. Make a log of a day and post it and experenced members will review it and advise what to do to get better battery life.
8. You need to ask a developer what the differences are. But I think AOKP is an upgrade of AOSP.
9. No trial and error is the only method. Your baseband and ril must match to get the most efficiency
out of your modem. There is a small program called GETRIL which will update the ril for you.
10. unfortunately everybody's preferences are different so it is another case of trying roms till you find on you are happy with.
I hope that these answers of some help.
@It_ler @Cosmic Blue
Thanks for the replies... I have a better understanding already. I've read up on GETRIL and will give that a try.
2) In SGS2 firmware, recovery (CWM is a special, enhanced recovery) is included in the kernel. If you format your internal memory (sd card), it will be removed, and will have to flash a new firmware (whole ROM including a new kernel with recovery) to your phone.

I understand. But is the internal memory partitioned? If I use X-plore I have a 11gig SD Memory and then I have a "/Root" folder which is 2gigs
Structure looks like this: /sdcard 11gb (10.9gbfree)
/root 2gb (1.7gb free)
Does CWM and Kernel not sit in /root? and is "/root" not a separate partition?
So...Instead of doing your own research & getting full/accurate answers to your questions (and learning a lot in the process), you'd rather sit here & wait for 'users' to give you mostly vague-ish answers to them ?
(Hint: By & large, developers do not read Q&A. They have better things to do.)
Edit - List of SGS2 partitions

MistahBungle this is a Q&A thread if you don't have any A's then rather don't post. I've had the Galaxy for 3 days. In 3 days I've read a lot and done a lot of research. You reply makes no sense that's like saying: "So Instead of failing many times and then getting it right you'd rather Google and get it right the first time?". I posted here because I know 90% of the people here are experts and will give me the answers I'm looking for. Also, I'm not posting questions like "OMG Lulz teach me how to root my phone" you can see that I've tried and these are questions that I have after trying out different ROMS.
Thanks to those that are willing to help, this is what builds a good community.
So that link I posted is an illusion, huh ?

OMW Oops :/. I'm so sorry I didn't even see that link I thought it was a signature. Thanks for the link you posted it is very helpful I'm reading it right now.
Before you start getting hostile please realise nobody on this site is obliged to help you and anyone who does reply to your thread does so in their own time and off their own volition. Beggers can't be choosers.
But otherwise your post isn't too bad. The differences between CM and AOKP are mainly cosmetic and to do with feature. There is no "AOSP" as everything is at its core based off AOSP. I always image AOKP as just a more streamlined, feature inclusive CM but recently they have started to add their own tweaks etc. Honestly, it doesn't matter anymore because with Siyah kernel (and kernels like it) being able to work on multiple platforms you can have ROMs with CM base and AOKP+Paranoid features.
The "features" I'm talking about are stuff like integrated weather, quick flashlight toggle, change the battery/signal display, etc etc.

I do agree that I should've responded in a better way, and that people are not obliged to help me. That's why I thank the people that do help. However, commenting on a thread and telling the OP to do his research doesn't seem constructive to me whatsoever (I've seen many threads like this). Posting a link is a quick CTRL+V and is way more constructive IMO.
Thanks for clearing up the differences for me. It makes a lot of sense. Everything is based on AOSP since that is the most "pure" release. AOKP is modified AOSP and CM is also Modified AOSP. So essentially most AOKP Roms take the best from AOKP builds and CM builds.
