SGS2 - Root / Kernel / ROM? - Galaxy S II Q&A, Help & Troubleshooting

Hi All.
I last rooted a HTC Desire well over a year (or 2) ago and I am now looking into rooting my Samsung Galaxy S2 - I9100, from Optus in Australia.
Although well versed, I am finding myself in noob land trying to read and firgure out what is the correct way to alter my phone.
Firstly I apologise for posting something that I am sure is answered out here. So please just point me to the right place and close this thread if so.
I can see that the standard boot loader (hope I refer to that correctly) appears to allow you to install another OS (ROM).
This appears to be called ODIN.
Am I able to load new ROMs by using the default ODIN on the phone, or do I need to load something like ClockworkMod?
I am intending to download and install the generic stock ROM (non-carrier) version before looking into other variants.
I am assuming to load other ROMs, like say Cyanogen 9, I would have to go through the root process.
Aside from rooting, I am reading posts that refer to updating the kernel. What is the kernel and why do I need to change it?
Thanks in advance for any assistance.

[Q] Custom ROM vs stock ROM

Hi people,
I've been reading up on flashing custom ROMs and might be interested to start using those on my rooted X10.
Question is though, can I easily go back to stock ROM in case I need to claim warranty?
I'm guessing by updating through PC Companion or SEUS, but I want to be sure first.
I couldn't find the answer in the forums, although I read quite intensively through the first pages of the dev & hacking forum.
Don't flame me, I've got my Android several months now but still consider myself a newbie, coming from WinMo...
Its easy to flash back to the original firmware with the flash tool. So if you wanna install a custom rom go right ahead.
Do I need to have the stock ROM at my disposal? Cause I can't find it for my carrier...
Yup. It's very easy to get back to stock firmware if you got an unlocked model.
However, if you are on a branded X10, you gotta find your exact branded version.
You can probably used the search button to find it though.

[Q] Country Specific Stock ROM

Hi,
I'm new to rooting the Galaxy Tab 10.1. I've done a ton of reading on this forum & was able to successfully root my GT-P7510 using bugs9477's stickied guide.
At the time I had a problem completing the root due to the scrolling screen with the CWM-based Recovery tool. As advised I unrooted my device using the P7510XABKMP_P7510UEKMP_HOME.tar.md5 stock ROM as per the guide.
I purchased an Australian Galaxy Tab 10.1. Now my device is using a United States stock ROM. It seems from my reading people aren't concerned about using other country stock or modified ROM's. I'm not worried about voiding the warranty using another stock ROM. But is there any concerns software specific pro’s or con’s I should be aware of when using another country specific stock ROM?
I searched for a stock ROM on sammobile.com. I could not find an Australian specific ROM. I did find an Open Asia ROM - P7510DXKG4. Did I not find an Australian ROM because it just doesn't exist & all Australian devices just use the Open Asia ROM?
At the moment I’m only interested in having a rooted device using a stock ROM. I’m asking all these questions because I’m thinking I might unroot back to a country specific stock ROM & then go through the rooting procedure. But if there isn't any real good reason to do so I won't bother hence the reason for my question.
I'm sorry if this question has been asked many times. I just couldn't find anything specific to my particular question.
Thanks in advance. This forum is fantastic & has helped me so much.
Cheers
Can someone please respond to my thread. Cheers.
No worries - thanks. I'm already happly rooted & used my first custom ROM yesterday being scrosler's CleanROM 1.4. Very happy with my experience so far.
I was only just wanting some answers regarding a stock ROM for my region. I'm not going to get to hung-up on the whole thing. I just wanted to know if for any reason I wanted to unroot & go back to stock for my region.

[Q] Need help with 10 questions... Getting started...

Hello All,
After 5 years of programming, hacking, and cracking iOS and iPhones i decided it was time to quit and start fresh, I got myself the Samsung Galaxy S3 4g i9305 / Telstra
I am new to this entire Android scene, therefore I have several question to ask... your help will be greatly appreciated.
1) I would like to try and remove the preinstalled carrier (Telstra - AUS) ROM and install a stock 4.1.1 Jelly Bean ROM (without any adds or added crap) – How can I go about doing this?
2) Can I back up my current factory ROM so I can restore it if something goes wrong or I change ROMS?
3) How can I root and unroot the device?
4) Are there any precautions I need to take? Are there any irreversible changes that can occur? The main question is; can I always return to factory stock ROM (from the factory), settings ect if something goes wrong?
5) What are Android equivalent to Cydia or Installous?
6) Benefits of rooting the device?
7) Similar Apps to ‘Get Apk’?
8) Best sources for themes, apps, hacks, ect? Maybe a usenet thread?
9) Any interesting tips, guides, sites to help me get a full grasp of the entire Android system?
10) Best ROM available for the s3 4g?
I am sure some of these questions might have been previously covered elsewhere, I have searched for answers but I am still uncertain on several aspects.
thanks you, and I look forward to your feedback.

*******DON`T install KIES. If your Rooting and flashing your phone, you won`t need it, and it could potentially get in your way******
The simplest way to get you started is to .....
1. Install Samsung USB Drivers on your PC - http://www.samsung.com/uk/support/model/GT-I9100RWAXEU-downloads# (works on all Samsung Devices)
2. Download ODIN (http://forum.xda-developers.com/attachment.php?attachmentid=1432843&d=1351270936 - self contained Executable, run it "as is")
Download this (Unbranded UK Official Stock ROM - should work OK) (http://www.hotfile.com/dl/177306141/248b29e/I9300XXDLJ4_I9300OXADLJ4_BTU.zip.html)
Go to this page http://forum.xda-developers.com/showthread.php?t=1671969 For an excellent guide how to flash your ROM using ODIN
Now go here http://forum.xda-developers.com/showthread.php?t=1957273 - Excellent Clockworkmod (CWM) recovery flashing guide
You should now have a rooted phone, with The latest official 4.1.1 JB, and a custom recovery flashed. Hope this helps..
If my phone has carrier specific rom, in my case Telstra, do i have to find another telstra? there is another guide here that uses the Optus rom (another Australian carrier) in this case Optus, can i use that one?
[GT-I9305] Australian Samsung Galaxy SIII 4G Root Guide - NOT for other variants
Is the process to unroot the device difficult? will something changeonce it is rooted?
I also noticed that once i get the phone into download mode, the seccond i press the continue button it goes straight into Downloading... Do not turn off target, and i cannot do anything other than hold the power button to reset...
Last issue i am facing, i have read many threads about this same issue, (it may be specific to Australian updates only) i cannot change,move, add, or remove any of the home screen (not lock) dock icons.. and yes i have tried every method but it may be very well something to do with the australian models as others have reported this problem and yet there is no fix for it... - so if i flash the rom will that fix the issue?

Please be aware that 9305 can have a different network circuit that the normal i9300 - read carefully the subforum for 9305!
Also you really need to start looking around - there is no magic tutorial, there are just a HUGE amount of separate posts (and with 9305 you need to be extra careful since there ARE small differences).

[Q] Custom Recovery and Rom Question

I'm sure this has been asked but I just wanted to verify I had my information correct, I have rooted and put custom roms on a gs3 in the past so I have little experience but don't want to brick my gs4 and it seems it may be a slightly difference process.
Essentially I want to get CM10 on my Verizon GS4
I found these root directions here http://forum.xda-developers.com/showthread.php?t=2290798
They seem pretty straight forward. I would assume I follow these directions and install TWRP or clockwork mod after its rooted then just flash my roms, however I saw something about Loki on another thread and getting around the bootloader. Do I have to do anything special involving that or once I am rooted can I just install the custom recovery from the app store and start installing roms...
Also how do I check if I have the update that just came out that prevents flashing roms.
Sorry if this was asked but I didn't see my specific question anywhere and I would really appreciate the help.
Also would you recommend going with the google edition or CM10?
Questions and Help issues go in Q&A and Help section

Im fairly certain TWRP is pre-loki'd now, so you wont have to worry about it.
In about phone, look under baseband version, If it doesn't say i545VRUAMDK then you have the new update that isnt rootable yet.
And for your last question, i havent tried either of them yet (I'm on hyperdrive).

[Q] The newest info on rooting/flashing i9300

Hello guys! I have an international variant of the S3, the i9300 since Jan 2013. Never flashed nor rooted the device, but the will to do that has been growing on me for a few months.
I've flashed only stock firmwares (the case where the newest firm wasn't available to my CSC) via ODIN, never rooted, never flashed anything else.
My question is: where should I look for the newest info on rooting/flashing the S3?
I remember there was a stock firmware released that changed the EFS folder, but I suppose that every customROM out there now takes that into consideration, right?
For the last year, I've been reading kernel this, TWRP that but never looked into the in depth definitions before but been reading into the matter since yesterday.
Also, flashing a customROM will make me lose videocall or the camera best definitions due to drivers or is it just a hoax/thing of the past?
Thanks in advance guys :good:
Go read the sticky thread in general forum, nothing has changed on rooting.
Custom rom is a personal choice, try them for yourself, those based on stock use the hardware better.
