[Q] Root and custom roms - Galaxy S III Q&A, Help & Troubleshooting

This might be the most noobish question of all noob questions but i have to ask since i can not find real information about it somehow. I have been doubting to ask it but will do anyway. So here it goes:
I want to root my telephone and been reading into it. Everywhere i find guides on how to root and flash custom roms. But (here it comes) : Is it needed to install a custom rom or is it possible to just root without installing said custom roms? I just want to take use of for example titanium back up apps.
I would be very greatfull for the answer on this question as it has been bugging me over the last week during my research on the topic.

If you haven't been able to find your answers it's mean that you haven't done your research properly.
Yes, you can just root your phone. Custom ROM or Recovery is an addition.

You can just root without installing a custom rom. Same goes with the custom recovery.

As Cool said above, you can Root and install a custom recovery if you wish, without installing a custom ROM. I Rooted mine within minutes of getting it home, but waited for about 2 weeks before I installed any custom ROMs on it. Sometimes it is better to get the feel first and then take the leap.
Moved to Q&A

Thanks for the answers. It is just all a little much information to understand it all at once. I'm sorry i posted in the wrong section, i thouht i posted right but sausage fingers. Going to give it a go today!

Maybe to you it's easy but i can't seem to find the answer that gives me the certain things to do/use.
Hopefully someone will give me the helpful/right answer (as i did in some posts) because when you take the time to reply it might as well be usefull.

Read post #4 of that thread. It has a WORKING link to the "[04/Jan][ROOTING/UNROOTING] DooMLoRD's Easy Rooting Toolkit [v4.0](zergRush Exploit)
" thread. (I say working because post #1 has NONworking link to the same page. Thread author didn't link it properly)
If you can't understand this and think it's not helpful, I would suggest you not root your phone. No offense.
Thnx i've got it.
I'm not a noob but there is so much info and it's sometimes difficult to read the correct things because of the language.

I think he's fine. He's in the Netherlands, according to his profile, so T-Mobile Europe, not T-Mobile USA... so he SHOULD have an I9100(and does, going by the screen shot of his "About Phone" screen in post #1), not an SGH-T989.
Im fine indeed
Now trying to find out what the Possibility's are now it's rooted.
FE: now it's possible to flash a custom rom?
What are the essential things i have to do now that it's rooted?

You could have flashed a custom ROM withOUT rooting. Indeed, there are several custom ROMs that come already rooted.
EDIT: Sorry, ignore the above sentence. I'm mistaken. You need root. My bad.
Sorry, but in my opinion, you went backwards on this. You rooted for the sake of rooting, then wondered "what can I do now that I have root?", instead of rooting because you needed to do something that required root. But I digress, and I'll get off my soapbox now.
That said, several apps that require root that I like are DroidWall (control what apps can access the internet via 3g and/or wifi), SixAxis Controller (use a ps3 controller on your phone - great for emulators), AdAway (ad blocker), Chainfire 3D (for Tegra only compatible games), Root Explorer (essential for tweaking files in system folders), Startup manager (control what apps are allowed to start when the phone boots), Titanium Backup (backup/restore applications and their data, freeze apps), and SetCPU (undervolt/overclock/change governors/etc).
First of all i rooted for the apps that need rooting like titanium and some other apps.
Second, indeed for flashing because i always thought it was essential. (saw your edit)
Third, i read some things about security issues (dataleaks fe.)and thought i had to root to solve them.
Maybe i'm totally wrong but as i said before there is so much info that its hard to pick the right things out of the topics.
Thanx for your help. Learning more everyday

Flashing roms two methods ODIN or CWM and now MOBILE ODIN .
If you want to flash a custom rom you read that roms install instructions no more and no less .
Most but not all custom roms are flashed via CWM
CWM requires root and CWM install .
Root + CWM .

OK getting further and further every minute
Now know that with the actual root i can't flash.
Do i need to unroot this root before Root CWM?
So i read this thread http://forum.xda-developers.com/showthread.php?t=1103399 and took Odin.
Now wondering wich CF Root to take.
My kernelversion says: [email protected]#2
Wich kernel i need to take:
this one: CF-Root-SGS2_XW_XEF_KJ2-v4.4-CWM4.zip
or this one: CF-Root-SGS2_XW_XEF_KJ2-v5.0-CWM5.zip
Or am i reading it wrong?
KJ2 might as well take v5 CWM
jje
And what about the unroot part? Do i need to unroot first and then CF-root?

I cant find my original Kernel version for removing the Triangle. Is it possible to find it on my device and move or extract it?

Helppp pleaseeeee!!!!!

ok...am not new to androids, infact i do a bit o' developing. now, a friend of mine sold me his x10 (white, unlocked, international version).
i have had LG's and Samsung's before, but never have had the pain as such. rooting and installing CWM and then installing a ROM was effortlessly simple.
am thinking of
1. unlocking the bootloader
2. installing an OC kernel
3. then testing out the awesome ROMs u all have....AND
4. port the superawesome PRADA ROM to the x10.
so, if any of you might kindly consider showing me the way round here, i shall be grateful.
P.S. - i tried to follow the tutorials on the general section, but i feeel am gonna mess it all up (and i frankly don't have much time getting it back again and start over from scratch). so please....

voila
I guess what you mean is how to start right?
maybe:
1. download the rom you'd like to go for and copy it to SD card
2. download the kernel flash using Flashtool
3. install the rom using Recovery
whether OC or not depends on the kernel, so watch out and pick up the right one.

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.

[Q] Root and data loss

Hello everybody,
I am sorry to bother you with a probably simple question. However, I could not find an answer on any of the forums.
I am using a I9300 for almost a year now. My plan is to install a custom ROM.
The brief question is, if I root the phone, do I loose any data?
Do/can I do a nandroid back up of my phone before I root it?
I have a the files and instructions to root/backup/install custom ROM. Just have this question before I start installing.
Thanks so much,
Y.

Hi guys I normally will search for the questions I have but im short on time and would like to know, 1. Is there a stock kittkatt rom that's flashable once rooted? Is rooting quick and easy with this phone? Thanks for allowing me this 1 time lazy Q and A.
Rooting is easy and fast and getting a recovery on it as well. Now to ur stock KitKat question. NO. But there are many custom Roms u can choose from.
