Hi All,
I am new to this forum and also to this Smartphone world
I am planning to buy Galaxy S2 , but want to use ICS Stock UI ( I can wait for official ICS update or use some ICS ROM ) , but what I want to know is that how can I use default ICS Stock UI on my Galaxy S2.
And another question when we use unofficial ROM on our Android phone , what are the risks we should consider in terms of our personal data security and also the stability of our phone ?
Thanks,
Maverick

If you do some reading around the SGS2 forum, you'll find all of the information you seek. Or you could try google...either way, the powers that be here at XDA aren't very friendly to those who don't bother trying to research, read, or use the search function. I'm trying to be a bit more personable.
At the moment, ICS is in either the Alpha or Beta stage...meaning that it's still buggy and doesn't really function as a daily driver yet.
To get ICS right now, you have to flash a ROM...which involves root access. The risks are pretty high. You have the risk of bricking your phone, if you don't read the instructions and follow them exactly, which isn't always easy because you're not very likely to find exact instructions for your specific phone (the hardware specs will match, but the ROM/Radio/Modem numbers may be different which can lead to confusion). You also run the risk of voiding your warranty, which is a pretty significant one.
I flashed an ICS build yesterday, and then my S2 wouldn't charge. I eventually flashed back (thank God I had made a backup yesterday, and 2 days ago as the one from yesterday didn't work!)
As far as security goes, nothing really to worry about. Dev's don't build in Carrier IQ and don't really want your personal data. But the flip side is, that they don't get paid for what they do...so if you have a problem or 'eff something up, you're pretty much on your own. You can ask for help, but again, sometimes the dev's don't want to be bothered with a question if it's already been answered or if you could've found the answer by searching for it. This is where it gets rude, sometimes.
That's the long answer. The short answer is READ, READ, READ...everything about your phone and flashing ROM's. Start at the beginning of the forum, as that's where the 'stickies' are and work your way thru. ICS will be released officially and stably later.
Hope that helps.
Thanks ,
I have googled it and read some threads on this forum and on others as well... thats how I came to know that you can root your phone with unofficial ICS ROM... but wasn't sure that in that case , will I get ICS with TouchWiz or Stock UI...
And 2nd thing that if I screwed up what will happen to my personal data...
anyhow thanks for replying my (dumb ? ) question
Hi Guys as my title Says..
i need Help very Badly.
First of all MODS and USERS i'm sorry i didn't knew where to post this thread so if its in in-appropriate section please move it to correct section. THanks
OK my problem is this.
i recently (less than a week ago ) bought a Samsung Galaxy S2 its by Bell Canada and its i9100M. i bought it online since my service provider is Rogers.
i guess this phone is already rooted to unlock it and i can see CWM and SU icon there.
Well i'm a Hardcore Blackberry Fan and have been using Blackberries from last 6 years. I loved the new samsung because of it looks and its screen.
I Had Lot of Problem with it like setting up my yahoo as push email, setting the Ringtone Profile, setting up the Custom Ringtones for Text Messages..
Having wrong time stamps on Recieved TEXT Message.. well i fixed all those by installing apps from market and forwarding my yahoo to my gmail...
i Hated doing all that but infront of the beauty of this phone i had to compromise but today it took 3 hours to find my gps location and day by day im using it i'm hating it .....
SO OK I DID MY RESEARCH AND FOUND OUT ALOT... the more i'm researching the more i'm getting confused...
first of all what is the difference between custom ROM and KERNEL.
i know custom rom could be like operating system but customized by unofficial person.
what the h is KERNEL..
to install rom's or kernel do i really have to root.
To unlock do i have to root or is there a paying method.
also i want to know if i'll go back to stock rom can i still unlock it.and recieve all the updates from samsung or google specially when ICS will be launched.
after unlocking and installing custom root. can i unroot it
and lastly which is best custom kernel and which is the best rom availble.
since been a blackberry user i have very basic needs. i don't play any games or download much apps and if an app is paid..i'll pay for it.. i don't want to jailbreak anything .
all i need is better battery life, gps and network coverage.
Thanks for taking time to read and reply.
Hi there.
I'll try and get through your questions as simply as possible,
Imagine your phone is like a car
A kernel is like the engine of a car - it's the low level machinery that keeps it going.
The Rom is like the body of the car around the engine. Roms can be official (or Stock Roms), or they can be customised by other people.
So, when you install a stock rom - you're installing the kernel, but you're also installing the radio (called a modem or baseband) and the registration (or the CSC which is location specific information) as well as the unique 'body' of the car for that rom - tweaks, default software, etc.
You don't have to have rooted your phone to install a Rom. When you update your phone via Kies, you are, literally, installing an stock rom. You can even install stock roms from elsewhere without rooting your phone. Because stock roms are released in different regions at different times, lots of people update their phones to the latest official roms via this method - no root required.
However, to install a custom, unofficial rom, you will need to root your phone as they will require access to the 'root level directory' of your phone's file system - which is what root really means.
You can find everything you need to know about that, how to root and also lots of stock roms you can install without rooting here:
Some shops will root you phone for you if you want to go down that path and don't want to risk it. But it's easier than you think and the galaxy s2 is very hard to break. There's lots of help available on XDA - just remember to search before you ask so you don't ask a common question the millionth time.
If you have installed a custom rom you can easily re-install a stock rom over it that will still work with Kies and thus be updateable when ICS turns up.
There is no 'best' Rom or kernel. Some Roms go 'as is' and some are customisable to the nth degree if you like fiddling with your phone non-stop. I personally use CheckRom because I like the kitchen app that lets you swap kernels, modems and mods with ease - but check out the Original Android Development threads and see which other roms you like the sound of.
Depending on what you are currently running, a new rom - even a stock one if you're running a very old one - could easily help with battery and range issues. For GPS - try installing FasterFix from the market and see if reassigning your GPS fix to a closer location helps.
Best of luck - it's a great phone once you open up its possibilities
Thanks a lot for the reply
well your reply did help me a lot...
my phone is been already rooted by someone else already from the person i bought it....
as for searching i did a lot.. and its been confusing me more and more ..well thanks for your answer
also as u said S2 is hard to break..i guess u mean is that the JIG thing on EBAY
and as for flashing the stuff i've played with other stuff just not android thing ive replaced the os on BB and jailbreaked iphones and installed macintosh on HP PC and also worked on most of the languages 10 years ago... and i believe nothing is impossible so going to someone else is never an option for me
just want to know as much as stuff i can before going further
well i have few more questions
how can i find which rom or kernel is already installed...
i mean is it possible to tell if its stock or its customized and its customized by which group.
and one last thing.. u know the words u used modem and baseband...
i read about it before...
but my question is ...
IS THE BASEBAND ANYTHING LIKE IPHONE BASEBAND???
u know in iPhones when baseband is updated u r screwed sometimes its hard to jailbreak and definately hard to unlock and reverting changes to baseband....
is it the samething in Galaxy S2 as well...
Thanks a lot for replying...i really appreciate all the time you took to reply.
Thanks once again.
Yeah baseband is the code that handles the phone part of your smartphone. Talking to your wireless provider, 3G, texts all these things are done by baseband.
Flashing a different baseband won't screw your root, and you'd still be rooted. Samsung doesn't make it hard to root as Apple does to jailbreaking. Even if something goes wrong with a new version, you can always revert back to old one using Odin(Samsung ROM flashing tool) and you are good to go.
Thanks a lot... about that quick reply...
i'm gonna collect more information and hopefully i'll be flashing it on weekend...
but how can i find which rom or kernel is already installed...
i mean is it possible to tell if its stock or its customized and its customized by which group
Everything you need to know can be found here. Most of it, anyway.
Backup your device with cwm when rooted ... So you can always restore to previous state. ;-)
Good luck there. But reading is a must.

also you can go settings - about phone - then look at the bottom fields to see kernel, baseband and build. Quote those and we should be able to tell what you have.

Hi everyone,
I am new to the android world having just bought a galaxy s2, so please be gentle. I'm a previous iphone owner and always hated the restrictions apple put on their phones and dictated the way I could use my handset! I've since moved over to android and my first impressions are OMFG, how confusing is all of this!! I'm not techphobic by any means but I am struggling to piece together how the world of android works and I have spent a lot of time reading various things about ROMs, rooting, flashing, kernels etc... but I am getting more and more confused!
I recently bought a Galaxy S2 which is running a custom ICS ROM on it (resurrection remix 1.0) and also has CWM on it. Having looked at the forums i can see that another version in out (1.3 i believe) but i'm very hesitant to try a flash as i dont want to screw my phone.
The way I see it i've got two choices, either try and reset the phone to stock so that warranty etc... remains uneffected and then update to ics through kies when its available or try and install a later version of one the ics ROM's that are availabe. I was wondering to that end if you lovely people coudl give me some guidance.
If I were to reset my phone to stock how do i do this bearing in mind i am confused about
a) what kernels are in the first place and
b) which one i woudl need for my phone and will I need a usb jig for this?
c) -i need to unroot my phone to return it to stock and if so how do i do this
also:
-what is the difference between an insecure and secure kernal
-if i flash my phone to a newer version of ics can i revert back to 1.0 as at the mo apart from the odd app crashing here and there I'm not having any probs with it.
I'm reading about GAPPS and APKs and dont know what the hell these are either but they keep popping up every so often.....basically i'm confused and on the verge of a breakdown!!
Please could somebody help mw with this and massive apologies if i've posted where i shoudnt have.
Thanks in advance
Saf
If you had taken the same time took for typing here to search and read you would have learnt almost everything...
go through these stiky threads
also see my links in singnature.......read as much as possible....no other substitute for reading and learning, nobody will answer you in essays like you typed
http://forum.xda-developers.com/showthread.php?t=1544657
Appreciate what you're saying mate and thank you for taking the time to reply. I have been reading various threads over the last day or so but the problem is when something like this which is quite techinical is completely new territory you dont know where to start. Google throws up page after page of stuff that doesnt make much sense and i've searched on the forums here and read up on quite a bit but again am not sure if i've grasped it.
problem is I didnt install the custom ROM on the phone, i bought it like this and to do anything further with it i dont know if i need to go back to the original owner with more questions or can i just go ahead and start tinkering with it without knowing what software was originally on the phone? (bearing in mind that various posts state that you need certain software which is as close to the original one as possible)
Thanks anyway
Saf
this is the stage which passed by all the noobs including me, dont worry
Your strating treble will only be over when you start flashing a ROM,
cool.
ima go ahead and try and install version 1.3 of resurrestion remix! Wish me luck hehe!!
Good luck,
dont forget to follow the steps mentioned the ROM thread atleast...
Hi All,
Please excuse the particular noob nature of this post. I have been doing a lot of digging and I just want to make sure I know what I'm doing before I launch into this amazing world of custom software and updates.
I very luckily won myself a Galaxy Tab 10.1 3g wifi (no idea exact model until it comes, as it appears there are a few....)
I have a galaxy nexus, but I've not mucked around with it at all really. A free galaxy tab though, is too much of a temptation not to.
So, in what order should I be doing stuff? From what I can gather it would be:
Root
Download ROM Manager
Install Clockworkmod Recovery
Make a NANDROID backup
From here, I'd like to use an AOKP rom, so I guess I flash that next, then install GAPP's.
Can you change kernel's when you like, or do they have to be done before the custom ROM, or after? Do they effect the custom ROM much?
Once both are on, make another NANDROID if stable?
There's a lot of guides on each step which I'm reading through at the moment, but the overall order isn't discussed that much. Hopefully I have a good jist of whats going on, and I apologise for bringing up such a basic issue yet again.
If it saves me bricking my new toy though, hopefully it will have been worth it.
I also currently use Widgetlocker and ADW launcher on my nexus. Will these work on ROMs? Are they needed? I notice that people post themes up so is there a seperate way of theming when on custom roms?
There's a lot of questions there, so I apologise for spamming. As long as I have the right order of doing things to start with, I'm sure I'll pick up ther rest on the way.
Thanks all.
If i were you . I follow this guide http://galaxytabhacks.com/galaxy-tab-10-1-hacks/how-to-root-galaxy-tab-10-1-the-easy-way/
once you have the Clockworkmod Recovery. Make a backup and install any custom rom you like. Yes, you can change kernel's after installing custom rom. Good Luck
Awesome. Thanks for the reply.
Can't wait to start mucking around with it.
Hi,
Ive had my Galaxy S3 for about 4 months now, and being in Australia waiting for the Jelly Bean update is driving me crazy, So i wanted to know how hard it would be to root my S3, I would have done it as soon as i got the phone however, My first galaxy stopped working after putting a new rom on the phone and my galaxy s2's screen turned blue and then died, although this could have been because i dropped it the day before, not sure both of these have kind of put me off rooting, however ive had a xoom and optimus 3d that are still fine on custom roms.
Also, If i wanted to return to stock, and unroot the phone, would that restore my warranty?
I have the International Galaxy S3, I think With Optus in Australia,
I would have searched how to root by myself, but i really dont want to brick the phone.
So if someone could link me to a stable rom and some instructions on how to root it would be fantastic
Thanks for reading
4 months..... I couldn't even wait for a day after received my S3
Even with custom ICS ROM you ll see huge difference
Hehhe I don't really care about warranty anymore after I chose to root
As long I enjoy the phone... But there's a way to do that...
I can't help you to find the link for rooting and apply CWM since I haven't been to any threads
If I were you, go search root by CF....
Good luck

Hi, Thanks for the reply,
I am going to follow this guide, Its from another website so my apologies if i am not allowed to post links to external sites, Although i found the link on an XDA thread so i figured it would be okay
http://www.androidrootz.com/2012/09/how-to-root-any-samsung-galaxy-s3.html
And im just looking at ROM's now, Just out of curiosity which ROM are you using androbot?
Thanks
I would always root my phone Just because you can use AD Block
Haha yeah i will look forward to that , Just Root'd phone then Tested with Titanium backup and works fine Just wondering if any of you could recommend a good ROM, or the ROM your currently using that your really happy with? Thanks
I'm using crDroid 6.3 at the moment...
I like ROM doesn't get stripped but still performs fast and fluid too...
Each user has their own taste....
The ROM is around 9xx mb...
It's got AROMA installer too....
After you root and install CWM, crDroid ROM requires touch recovery to avoid any problem...so you need to flash touch recovery recommended ...

I gave stock a try for a while.... Lasted 3 days. Samsung managed to create something that can't run on a quad core phone.... That's almost something to be proud of, I shouldn't experience lag and homescreen redraws on a $500+ phone. Installing a custom rom is a must for me, I don't understand why OEM version of Android are so horrible but they are. Rooting only will give you a few benefits and extra things you can tweak as well as ad blocking and making the GPS faster. But if you really want a change, custom roms are the way to go.
Hey guys new to android based phones, ive had the s3 for a few months and have read the forum for a while, i want to flash a custom rom and read about imei backup which i just did but i want to know is it common for the imei to delete when flashing?
I lasted about 3 weeks on stock.. now dual booting CM10 & UltraROM. You won't regret it :good:
Should I root??
Sorry for posting here but it's the closest I have found to what my question is. I have an AT&T S3. I would like to root to get rid of my bloatware but I'm a chicken. I rooted my HTC Inspire over a year ago and I didn't really know how to remove to AT&T apps and the stock rom was not as snappy as it was prior to rooting. I planned on staying on ICS until an official JB OTA was available, as I've never flashed custom roms before. What I'm most concerned about I guess is whether rooting will mess up my 4gLTE and wifi. I rely heavily on wifi since sadly, AT&T is lame, expensive, and doesn't offer unlimited data. So I want to make sure I don't screw up wifi if I do this. Can anyone provide insight or point me to a good resource that can help?? Thanks a bunch in advance and sorry for the noob questions.

Using Odin to flash CF-Root is super-easy, so don't be afraid. Rooting will not affect your phone's smoothness, but if you use it to remove apps with Titanium Backup without making sure they are not useless, you may end up having performance issues or worse. Of course, I'm not saying you shouldn't root, just that after rooting, take care with what you remove via TB.
CF-Root can be found in the Original Android Development forum, follow the instructions and you'll be ok.
