Hi all,
I'm new android user. I want to root my phone, but not sure about what to do before rooting (I already have some basic idea about how to root). Do I have to back my current firmware? Is it possible to Unroot my phone? (to make it is in the same way as it is now). Sorry for my bad English.
New Android user.
firstly make sure that your phone have full power，that is very important.

You need an advanced recovery
What is your phone? Try to check in Google 1 click root method
State your phone? Rooting is easy, you usually need your phone, the root file, a computer, USB cable and a software called Odin. And yes once you get a recovery, you can backup your firmware and reflash a stock ROM to remove the root.

You're assuming that they have a Samsung phone for some reason...? Odin only works on Samsung devices.
OP:
You need to know the phone model as well as the build version of the software - not just the Android version - as different updates typically have different methods. You should backup all of your important data to Google and/or your PC. There are a variety of different ways to do this including many apps in the Play Store that can help. It would be advised to save your pictures, music, etc from your internal storage or sd card to the PC for safe keeping as well. You should also make sure that you can find the original full firmware and guide to reinstall for your phone in case you do want to unroot or if the phone does not work properly due to an error or bad luck.

I have just gotten myself a SG2, my first Android device.
I probably wouldn't want to root, at least so early, if it weren't for Root Call Blocker Pro which I want/need to install.
So I wanted to ask a couple of related questions:
1. Is there a way of rooting without losing all the apps + settings? If not, can you recommend a could backup app?
2. Could someone please point me to the EASIEST step-by-step guide on how to root a SG2? I have found a couple of threads but am not sure if they are the most up-to-date/best/most appropriate for a novice.
3. Will I be able to apply the official SG2 updates from Samsung after rooting? (OK, so that was three questions....)
Thanks!

Now THAT is detailed!
A follow up question though:
Exactly how does this rooting work under the hood? Why do we need to look for a compatible file that we then use to replace.... what?

Rooting using CF-root replaces the phones kernel (core of the OS) with a modified one, with clockworkmod recovery (nandroid backup, etc), it also includes insecure adb (adb that can run as root not just standard user) and copy's the superuser apk to the system dir and sets permissions.
This is all done via a special initramfs attached to an otherwise stock kernel.
why would you want to root and then use OTA stock roms?
If you find you can't get OTA stock updates after a root (i.e. if Samsung decide to utilise some mad kernel reset counter ban hammer) then simply check XDA where I guarantee the OTA stcks will appear pretty quickly!
Things to consider:
1. Rooting is very very good for numerous reasons that can be found everywhere on XDA - and google.
2. You can replace the kernel for root but continue to use stock rom (and use a jig to replace the reset counters) for pretty much stock functionality.
3. If you root and don't like what you get (i.e. you're mental) then it is just as easy to replace all factory rom/kernel information (which are always available in the original development thread) but you should invest in a jig (from ebay) so you can reset the counters (you can do this via software but I find a jig far simpler).
What JJEgan said.
Rooting won't lose your apps. Titanium Backup Pro is the best way to go.
Install Kies, exit Kies, open Odin, phone in download mode + plug it in, don't touch any of the Odin settings, load "PDA" with chainfire's kernel -> go!
It's really straightforward, but it can be a little nerve wracking the first time.
Thanks a lot guys!
I just rooted, and it "only" took me about 15 min including the downloading of the various files (still way more though than the 30 sec. it should take according to the Chainfire post!! ).
@m4rshall's summary made it clear that the steps are really very few and simple, because when you read the other posts, it seems like a much more complex process due to their size, though they are absolutely necessary to get all the details.
Some follow up questions:
1. What would I need to do if I wanted to the original, factory state?
Not that I'm planning to, but in case I notice some issue that makes me decide to go back (I read in that loooong thread that some people noticed slower connections after rooting??)?
2. From what I've gathered, the yellow exclamation mark at boot is purely "cosmetic" and does not effect in any way at all the performance of the device. Correct?
3. The USB jig: exactly what does it do?? How does it do its magic?? How is it different from a normal cable? Are they only used for Android rooting?
Thanks again!

Clockworkmod recovery is a replacement recovery, it allows you to preform full device snapshot backups, to allow you to restore your phone to any point in time.
Allows you to flash CWM compatible zips.
Mount your SD to a computer while in recovery to copy things to it.
Well it's regarding rooting.
I heard it opens up a world of opportunity with your smartphone, and some apps I really want are only available vain rooted phones. I have the Samsung galaxy s3 international version. It was originally from Australia if that matters at all. It is on 4.0.4. Anyways, being a noob to android more or less, and being a bit apprehensive (because I have no warranty and I cannot obtain another phone easily) I was wondering basically how risky it is to brick your phone in a) the process of rooting your phone. Is it common? If it does get bricked is it reversable by a restore or simply gone? Also after rooting, is there any upkeep or management I need to do to make sure my rooted phone does not screw up? And lastly. What is the safest and easiest way to root the international quad core gs3 on ics. Thank you to everyone for your time

Well, most you could pick up be reading a bit, everything is already explained around here but since i was in your shoes very recently:
- there's always a risk. You need to be aware of that. That said, most cases that actually go wrong it's usually user's fault who failed to follow instructions closely. So read them. And read some more. And then read again just to make sure. And then i'd read again.
I used this very recent method from chainfire (salute and donate to the man if you like and can, he deserves it) to root my 4.0.4 international GT-I9300 S3:
http://forum.xda-developers.com/showthread.php?t=1957273
Triangled away next and everything worked like a charm. This preserves everything as stock as possible just adding root to your phone.
- from what i can tell, as long as you don't do anything that messes with the bootloader, you can always recover from a procedure gone wrong. Just disconnect, remove battery, insert and try again. Rebooting the computer or changing usb ports usually helps too (on odin).
- after rooting successfully, the very first thing you should do is backup your /efs folder. This is easy, just pick up root explorer or some other file manager that allows exploring you root (/), go up in your folders until you get to / look for the efs folder and just copy it (NOT MOVE) elsewhere (sd card, external sd, your computer preferably, whatever, just have that safe). This will come in handy in case you lose your imei at some point. Just restore this folder's contents and you're good to go. If that happens and you don't have a backup, it's a f'ing pain you can do well without.
- anything else root related is just common sense. Since you have the potential to screw up your entire phone with root permissions (this is why you don't have them in the first place), if an app pops up asking for root permissions, be sure what it is before allowing. If you're not sure, you can always deny first and allow later in the superuser app.
- you can also look into backing up with nandroid. You can think of this as an image of your entire phone. With this you can restore your phone to the same state it was when you did it. Useful when something went wrong and your phone doesn't boot anymore or you just wanted to try new roms with the option of coming back to what you had before. Not sure how you do it on the S3 still, but it usually requires a modified recovery like CWM. The method to root above doesn't install one though, it preserves what you had. Check this instead if you're interested:

Thankyou very much to everyone who has read and replied to this. 3 more minor questions. Is there a way to first update my phone to jellybean 4.1 via Odin or something like that? Or is this possible after root, because I don't want to stay on ics. Also what exactly happens if I update while rooted. Does it wipe or unroot my phone or the like? Also should my phone be in use debugging, and lastly what does it mean to unlock my bootloaders? That was more than 3 questions sorry thanks again

1) You don't need to root to update to JB.
Just download any ROM you want from http://samsung-updates.com/device/?id=GT-I9300 (I recommend the UK unbranded ROM, BTU) then use Odin3 to flash it to your devices. Search the forums for specific instructions on this procedure. I'll just tell that it takes no more than 2-3 minutes.
2) If you're going to root, I suggest you do it beforehand, by flashing a kernel like Siyah (in ICS), and then proceed to flashing the stock JB ROM, HOWEVER, instead of using Odin3, you will use MobileOdion (available from Play Store), because that way you'll have a fully rooted and stock device.
3) Using step 2 above, it will not wipe not unroot your phone. It is safe and retains all your settings. That is the beauty of MobileOdin. There is a free version.
If you root and THEN install via Odin (PC), then you'll lose root, but not your settings.
In either case, you only wipe the device IF YOU WANT TO.
So, the best option is to:
a) Install SiyahKernel using Odin3 (PC)
b) Download the JB BTU ROM from http://samsung-updates.com/device/?id=GT-I9300
c) Extract the .md5 from the ZIP file and move it to the device's ext. sd card
d) Install MobileOdin in the device
e) Use MobileOdin to flash the .md5 you moved to it in step (c)
f) install TriangleAway (download from XDA) and run it to reset binary counter (which got incremented in step [a] )
Results: rooted, JB, stock, all settins retained, no binary counter increment
Simonetti2011 I have been searching the internet here in New Zealand and that has been the best answer I have found so far!
I do have a slight question thought. I live in New Zealand and have the GT-I9300T model of the GS3 and I'm wanting to install the international unbranded rom for that I can get updates faster (here in NZ it takes months and months to get updates)
I downloaded the International UK unbranded firmware 4.0.4 and was going to flash that rom onto my phone then upgrade to jelly bean via kies but have since relised I should just download the jellybean UK firmware straight away. Do you by any chance havea link to the firmware that I would need, I noticed there were a few different versions.
Also about the CSC, would I need to do any changes?
Many many thanks in advance, Sorry for hijacking this thread, just figured I was on the same pages as the OP

Thanks!
The 9300T and the 9300 are NOT the same device, therefore they use different firmware (ROM). The ROMs for the 9300T are here: http://samsung-updates.com/device/?id=GT-I9300T
I don't think there is a 9300T ROM for the UK, since the model released there is the 9300 (non-T).
It seems that either Samsung-updates hasn't indexed any ROMs for your model or they haven't been released.
About CSC: just don't worry about it... download and flash any ROM you want for your specific model and don't worry. If you don't like it, just download and flash another one.
Thanks heaps for that!
I actually just tried the UK unbranded rom that was for the i9300 on my i9300T and suprisingly everything seems to work ok so far (phone calls, txting, 3g etc)
Thankyou to everyone!
Thank you for your responses to my post regarding rooting my s3. They were very helpful. i succesfully rooted via chainfire cf auto root for the I9300 model without problem. Just one last question, I have been searching around a bit and some people are saying that flashing the jellybean firmware via odin, is not a perfect copy.. i mean some say they have been experiencing very minor problems here and there. So, if i update to the uk firmware on jelly bean via odin or mobile odin, and i experience some problems, can i still get the official ota update or jellybean 4.1 via kies when it is released? Thanks again for your help. Im pretty new to this android stuff
Ok. I have at&t Samsung galaxy note i717. Earlier today I manually updated the software to jelly bean 4.1 and also unlocked it by following a YouTube video. Now. I have downloaded a few things, such as SU, CWM, titanium backup, twrp, and I think that's it. I barely know what any of these things do. I have already deleted all bloatware from my phone. I went to TWRP and I backed up my current settings to my sd card. I guess that's out of the way.
I am asking if anyone can please explain in detail and retard terms, what precautions should I take before I figure out how to flash new roms and kernels, and if i backed up my phone correctly so if I screw up, I can restore my phone.
I need someone to explain to me what process I should take in order to keep my phone safe and secure, how to get a rom for saving battery... Do you need to connect to a computer to do this? Someone please explain to me how to use all of these apps and roms safely! Thank you

My opinion. Dont mess with it. If its battery life you're looking for go to amazon and buy an extended battery.
Flashing roms and kernels without having some sort of idea what you're doing could completely brick(ruin) your phone.

I want to continue to research and learn about it so I don't hard brick my phone. I was hoping someone could at least explain the apps that I have downloaded. What each do. How to back up my phone settings to my sd card. Do I need each app that I downloaded, and when do I need to connect to a computer? When I go online and find a new rom and flash it over with Odin?

SU is superuser. its for rooted andriods. basically when you try to go into an app that requires root superuser is what will grant that app permission to do what it wants to do.
a rooted android must have su or it wont have root access.
cwm,titanium backup, twrp- The only one of these i use is cwm. clockwork mod is simple. a stock phone has its own recovery. power on while holding up/down vol's and it boots into recovery. cwm is a modded recovery that allows you to do more. you open it the same way as the stock one but from there you can backup your entire phone, -roms and all. the way to put it on your phone is to download the appropraite one for your android version and also download odin. when odins open click pda, find the file, start phone in download mode (vol down and pwr) and click start. now there are a ton of tutorials but thats the gist of it. now after its back up you can try to flash roms, kernels, etc. most of them will be flashed via odin some you will drag onto your sd card and flash them via cwm(the install zip from sd card option).
When it comes to flashing stuff on your phone nothing is 100% safe and a backup isnt always going to fix a problem you may cause. dont flash anything you havent done research on. read the entire forum to see what problems people had and how they fixed them.
Most downloads youll find have step by step instructions, follow them.
Good luck
Hi, I just got an i9300 used at a great price, but after some reading I'm overwhelmed at the amount of guides for it and information. Right now it's on the official stock ROM (latest firmware). I want to restore it to factory settings (it still has some of the previous owner's customizations), and root it so I can remove the useless apps like ChatON.
If I'm using Kies and Odin, would I need to back up the EFS data? Also, if I root, I would have to flash again via Odin? Is there any possibility of devices becoming bricked due to using Odin?
I just want to use the stock ROM with root.
I'm upgrading from an Xperia U, but this phone seems a lot more complicated. With the U I could use flashtool without a care.
I appreciate any help I can get.

(1) ALWAYS backup EFS, doesn't matter what rom or tool you use to root
(2) There is always a chance of bricking a phone, nothing is 100%
(3) Read this and this
(4) After rading, you should be able to answer your questions by yourself, if not dont root or flash.

Thank you, I understand it a lot better now. I've been reading repetitively. I used kTool to back up the EFS which saved it in two formats (IMG and TAR), I suppose this is good enough or should I use the other tools? I went with kTool because it seemed to be the easiest.
I've rooted and removed bloatware, and I understand when Samsung releases new updates, I would need to flash via Odin and re-root, right?

I have to upgrade my My Samsung Galaxy S-II from Gingerbread to Jellybean
my but mobile does not connect with PC as USB connector is broken.
So, up-gradation with Odin or Kii does not support.
Alternatively, I have to update over OTA but mobile says that the latest updates have already been installed.
So i found an option in Boot Menu which says "Update from SD Card"
Now my question is that:
If I place official jellybean file in Phone Memory or Memory Card
Will it be update from there?
if Yes, kindly guide me.
If not then kindly also guide me how to update my Galaxy-S2.
Regards.
The very first thing you have to do is get the USB port fixed.
Modifying the software on a phone will *ALWAYS* carry an element of risk......
Sometimes, if things go wrong, the only way to put them right is to flash a firmware with odin.......
How do you use odin?
You install it on your PC and connect your phone to your PC via a cable and the USB port.....If your USB port is broken, you have a device you can't fix.
I personally would advise you NOT to modify your device until you have the port repaired.....
If you want to try it yourself, I wrote a guide which explains exactly how to do it.....

Will it be updated ?
Afaik it won't work.......
I think you use the stock recovery to flash only zip files.......
Firmwares come as .tar files which recovery can't deal with......

You can try using mobile ODIN: http://forum.xda-developers.com/showthread.php?t=1347899
I think you are not receiving OTA updates because probably your phone carrier stopped shipping updates ages ago.
Of course you will need a rooted phone to do this. You will need to download the latest firmware onto your phone (you can download from sammobile.com), unzip it with es file explorer or alternative file manager, then select the files according to the corresponding categories.
Alternatively (and I think this is a much safer option, but can be tedious for new users), root your phone with a custom gingerbread kernel or cf-auto-root, install a jellybean compatible recovery or jelly bean kernel such as apolo kernel, then install a stock based rom such as neatrom (I will give instructions if you decide to do this way). This way, you still have a newer version of android minus all of the bloatware from samsung.
In other words, without root and OTA updates from phone carrier, you pretty much left with no option but to fix the usb port on your phone.
