New to Galaxy S2 rooting, few questions. - Galaxy S II Q&A, Help & Troubleshooting

Hey guys well I am coming from a Desire HD which was pretty simple, you basicly have roms and kernels to install and I got the hang of it pretty quickly.
But I am upgrading to an S2 tomorrow and reading through the forums everything looks a lot more complicated, and I am reading about things like Modems (whats that) and so on.
Just wondering if any one could link me or give me a complete guide on everything to do with rooting, improving galaxy s2's?

Did you miss all the stickies and FAQ's?

Nope, I looked through most of them actually...

SGS2 flashing once you get root is as easy as it could be with any phone, just flash the ROM via CWM.
The "new" part if you come from Desire is the use of Odin to first enable root on the phone, but you can see good tutorials/guides here in the stickies.

[Q] Root Samsung Fascinate

I am new to the forum and I am looking for the easiest way to root my fascinate sch-i500 phone. It has Froyo 2.2.1 currently. Any help is appreciated.
No worries. Use Z4 root, its a one click method which will do what you want rather easily. I posted a link below to a thread which includes the apk file and instructions on how to use it.

If you just want to root, find a one click root app. If you want to flash roms :
One tip: Read the stickies in the Development section. Your better off knowing what your doing instead of blindly following our advice. Sorry if this comes as a bit of a downer, but its for your own good.

^ Yup, he's right...The z4 root apk I posted does work 99.9% of the time without a hitch but sometimes things don't always go as planned and you may end up having to Odin because of it. Like TheSonicEmerald recommended read though the stickies and see what it will take to get your samsung fascinate back up and running again if something were to go wrong. It will save you a lot of time when it does happen, and believe me, if your going to be flashing roms and such things WILL go wrong. This isn't to scare you or anything, it is to assure you if anything goes wrong the forum is here to help. I've learned this one word of advice over my time here and thats, "YOU CAN NEVER BRICK AN ANDROID PHONE."I hope this helped you out a little. Happy modding.
I'm not new to rooting at all, I have rooted several devices. A friend of mine just got a Fascinate and all the info I'm finding seems old and depricated. Will this z4root still work? Is it simple enough for a newb to do? She really just wants root for the wifi tether for root users.
I couldn't agree more. I read a ton of stickies and it paid off big time

New to I9100, couple of questions.

Hi everyone, I bought a galaxy s 2 I9100 from somebody Nd the phone is great. It is already rooted however it doesn't have clockworkmod recovery installed. How do I install it on my phone? And when I do can I install any I9100 rom or does it have to match my kernel version XWKDD? Thanks sorry I'm a noobie to this phone
The easiest way to get it is to flash Chainfire's CF-Root kernel.
But, just a word of advice: don't flash anything until you read and understand the basic procedures for flashing a ROM or kernel, etc., because it's NOT that difficult to understand, but you can mess up your phone by doing dumb things, most of which are already covered here. So, give yourself some time to absorb the basics before jumping in and getting yourself in trouble.

Ah, well, then you should be fine. The basics are the same for all the S2 variants. Just know not to flash any of the G series ROMs (and avoid Re-Partition in Odin) and you are all set.
Like I mentioned, it's not that complicated, as you apparently already know, but almost every time problems arise, it's from following advice from another forum, at least from what I've observed anyway. They'll say something about "I followed this guide...." and include a link to a four year old post in some other forum about the wrong model or something and act stunned when they brick their device because they followed the bad advice.

I'd suggest you start with a stock ROM, such as the latest KK5 and use the CF-Root kernel (as in my signature). You could always venture into custom ROM territory later, after you get a feel for it.
I tend to gravitate toward stock experience myself, and I love JKay's mod which works well with stock ROMs, but there are some terrific custom ROMs here to choose from, if you feel so inclined.

[Q] How to put roms on etc

hi all i just got my galaxy s2 today and have no idea where to start with putting a rom on ot anything. so any help would be great thanks
First you need to be rooted(your phone not you)and then go to the Development section and you will find a list of different ROMs.Its a matter of finding what you want in a ROM and downloading and trying each one.Usually the ROM page has the download and install instructions writen on it.You need to be rooted to have CWM.Ill leave a link to my ROM so you can see what I mean.Below the different ROM versions you will see install instructions.If your not sure what root is let me know
http://forum.xda-developers.com/showthread.php?t=1290468
Spend some time using your phone to get used to It before flashing. This will give you a better idea of what you like and don't like about it.
Armed with that info you can read up on each custom Rom to see if they offer what you want.
Read read and when you think you are ready to flash read some more.

X2 read alot, play with the phone, figure things out. There is so much to learn so you don't turn your phone into a brick. Rooting means you become a superuser, you take ownership so you can customize your phone.

Please don't even think about flashing a custom rom or rooting your phone until you're comfortable/confident enough to do it without making posts like this.
I have seen so many people in your situation on here stuff their phone up over the last few weeks because they were in too much of a hurry to mess with their phone.
AceOfClubs (and others) has given you good advice, heed it :-|
Read the CFRoot thread until you are so confident with rooting the phone that you could do it in your sleep, and then root your phone with the CFRoot kernel that corresponds to your current stock kernel. Not before.
From there, read the various development threads about different roms/kernels, get to know the various features/advantages of each (and ask questions if necessary...about the rom/kernel itself, not the process of flashing same) and then when you've settled on a rom or kernel and you're completely confident about the flashing process, flash it.
Doing this will mean you'll get it right the first time. This will result in:-
A) You not posting yet another "OMG mah fone is teh brikked helpz !" thread.
B) You not having to do without using your phone for x days (weeks) should you mess it up.
Clear ? Good

Root is changing the kernel in your phone to give you super user access which is needed to flash ROMs and firmwares.Also along with flashing there are other things to read up on like an EFS/IMEI file backups which are vital,also nandroid and Titanium backups.As you can see there are alot of good people here willing to help with good advice and all are correct in saying that you shouldnt rush into things.Take your time,read up and dont be afraid to ask questions.Play with your phone and when you know it well enough and have seen enough threads on what and what not to do then you can take the first step and root.First read up on rooting then EFS/IMEI backups and why they are needed.The rest will come in time.Id rather see you here asking questions and not in another thread saying "Help I just bricked my phone!!"

How to root and 'best' ROM

I'm a noob who needs to learn how to root their sgs2. First Android phone but I'm looking to open up and get more from my phone.
Also there seems to be so many roms and people taking of bricking. If anyone could explain the 'best' rom and what to do once my phone is rooted I would appreciate it thanks

If you don't know what you want root for, I'd suggest not rooting.
The best ROM is <insert name of ROM here>.
My advice: stick to stock.
Man, people need to use the search button nowadays :/
As well as Google.
If you're an Android noob and you start rooting, there is a high chance of failing to root HENCE a brick would occur. Most bricks you hear or see that people get are from careless actions or they don't know what in god's name they are doing.
Do not make that mistake.
Research before attempting because I assume no matter what, you want your device rooted.
Make sure you have an GT-I9100 device, check by turning on and off your device.
The best ROMs I have used, and maybe you should stick to for a while, is either CriskeloROM, SensatioN Rom, CheckROM or Lite'ning ROM, found here: http://forum.xda-developers.com/showthread.php?t=1253665
Use Odin to flash a custom kernel, for example Ninphetamine: http://forum.xda-developers.com/showthread.php?t=1179814
Follow guides on ROM pages to install their ROMs, installing a ROM automatically roots your device.
Good advice from previous poster.First read up on rooting and what it brings to your phone as it doesnt just bring flashing rights.As for bricking,its easy to brick your phone if your not carefull and dont read the instructions well and put the wrong kernel in Odin.Its an easy proccess but some people just dont follow the guides.Bricking in some cases is self caused.The ROM thing is a hard one cos there is no perfect ROM when everyone has different needs so its a case of read each ROM thread and choose what you like.If you dont like it try another.No one here on this site who knows what they are doing,Im quite sure,has only ever flashed one ROM in there time here.Best thing to do right now is stay stock until you read up on some important facts about flashing
1.Rooting,how why and what it brings.
2.nandroid backup
3.EFS/IMEI backup and restore-super impotant cos if you loose this info your screwed
4.the difference between each one and what each Dev brings to his/her ROM
5.Flashing.Some are done via recovery and some via odin.Also bootloops and how to get out of them
if i were you i'd first read all bout roms/kernels till your eyes bleed
then once you know how to do it, well pick a kernel and a rom which suits your needs
learn from people mistakes, i usually read couple pages on how people messed up while flashing so i dont fall in the same, and in case you brick your phone also have a way to recover it prepared
Maxwell0;2109742
Also there seems to be so many roms and people taking of bricking. If anyone could explain the 'best' rom and what to do once my phone is rooted I would appreciate it thanks :)
As asked if you know nothing and that knowledge is so limited you have to ask the banned question what is best rom then stick with stock until you understand .
Likewise why root if you dont know why .

Sgs2 ics 4.0.4 help!!

Hey,
So I upgraded my Samsung Galaxy S II I9100 to ICS 4.0.4 before 1-2 months. The new graphics and extra features looked really great at first, but 2 hours after using it on normal applications (Facebook, YouTube, Twitter.) It froze and did nothing, like literally just freezes at the screen it lagged on. This has been happening continuously for the past 2 months and I'm really sick of it, I upgraded my phone and my dad's one (both SGS2I9100) using Samsung Kies, ever since that, it just keeps freezing like 4 times a day and I have to take off my battery and re-put it so it can reset since nothing will do this.. The old the firmware I had was the really amazingly going well and never lagged even once (I can't remember which firmware though). I'm a total noob, I didn't and don't have my phone rooted or some stuff like that, expect downloading APKs off the internet lol.
I really want someone to help me in this, I know there must be a solution since I don't think I'm the only one who has been annoyed by this, specially when it happens on a daily routine. I searched over the forums and found nothing. I know there must be something talking about the issue but I'm too nooby to understand the article titles which might be a solution of my problem.
Please help me in my problem it really bothers me and xda is my last hope...
Thank you all.
Note: please use simple terms because I really won't understand, and if you do, please teach me them lol.
Well, first of all your up for some reading.
While you go from thread to thread you'll run into the world of ROMs and flashing.
The first thing you have to know is that your device comes with 4 things:
1) Hardware (dah)
2) Kernel (link between Hardware & OS)
3) ROM (OS)
4) Modem (Baseband for your country / Region)
You are actually on 4.0.4, It's Kernel is known to suffer the brick bug issue.
Flashing is used to get the best from your device, in relation to your personal user experience. You got plenty of options like Stock Roms and Custom Roms, as well as Stock Kernels and custom kernels.
When flashing stock roms you get the chance to get rid of your carrier stuff (bloatware and animation boot) by getting an unbranded ROM (samsung official stock rom), you can either go down to previous versions (Gingerbread, ICS 4.0.3) or even go up (Jelly bean leaked ROM). Carrier branded or not, it's just a matter of choice.
When flashing custom roms you get a whole lot of roms to choose from. The most common are CyanogenMod (CM), RR (revolution remix), Omega and etcetera. These roms take the best of the stock roms and leave the worst, so you'll get a more personalized experience.
When Flashing custom kernels your trying to get the best performance for your ROM, this means you can use a stock ROM with a custom kernel.
Modems are basebands that let your carrier network function in your region / country, so if you flash a modem, your network might not work, so you'll have to flash another modem and so on.
Check all that out and if you decide to go on flashing, we are here to help you on the easiest / safest way to do it.
rembember to read and re-read all first.
you did notice this is now your official post right?
Okay I kinda get it, can you kindly please send me links that will help my problem? I'd rather downgrade with Stock ROM than a costum one.
Another thing, will it affect anything that has to do with my Carier? and does my phone have to be rooted in order this to work? If so how can I?
Many thanks.
Sent from my GT-I9100 using xda app-developers app
try sammobile.com
they have plenty of stock roms.
I'd personally advice you to get 4.0.3 stock ROM. What's you carrier? I could look it up for you while you learn about flashing/downgrade.
That's what I was thinking of too, and it's Orange IL (Israel)
I need you you to tell me how do it too please

When the guy doesn't read it was a good advice to start doing it, because it's not really allowed to ask everything that is allready asked so many times.
When he actually does read, but doesn't understand (which I don't think because he's asking basic question about steps he must take) then it's maybe better to rethink if he's really going to flash something because he doesn't know what he's doing

Why don't you just flash a stock rom through Odin? No offence but I'm serious, the lack of knowledge you show here by asking about Recovery to me seems to be a sign you shouldn't root it at all, and learn a whole lot more about flashing and more if you want to.
