Which is the best way to root and unroot a Samsung Galaxy S3 I9300?

I have a Samsung Galaxy S3 I9300. I am considering rooting it as I have heard it has some benefits, some of which would be of use to me. My question is what is the best and easiest way possible to root and unroot this phone?

I have read a guide at AndroidForums and it seems pretty good. I have also seen the XDA method, which I didn’t quite get. And then there is the Unlock Root software mentioned right here on MUO which does support my I9300XXBLFB build.

I am confused as I really don’t want to brick the phone and I don’t want to install a custom ROM as of now. Also the AndroidForums method shows that I have to flash it with stock firmware to unroot it. Is that really necessary and will I lose data if I do that? Also do I need to install the CWM recovery? What is it for?

I know it is lots of questions but I’m just an Android beginner! Thanks for your advice.

    Rooting voids your warranty, and also, if you perform some of the actions that give you the advantages of rooting, you could end up damaging your OS. Rooting also has advantages, such as being able to remove bloatware from your system partition.
    Also, in case you wish to install a custom rom (os version different than the one released by samsung for your device), then you will also need to unlock the bootloader, if it is not already unlocked.
    xda developers have a nice tutorial for the same, available at this link:

    I personally own a Xperia play, and use super one click to root it, and also, this application has unroot function as well. SuperOneClick is also available on the XDA forum if you care to search for a bit.

    I think the CF-Root method with Odin seems to be the best.
    Thanks for the response guys.

    Clock Work Mod isn't necessary if you want to risk bricking your device when altering your phone's OS. It helps you to get out of tough situations where if you don't have it may cause your phone to be completely unusable. You don't have to flash a stock OS to root your phone, but using Odin to root your phone is Perry much the norm now. Super One Click works wonderfully, but not on all devices, and I have yet to see a device brick from using it. That might be what you want to try first, but Odin works well, just scary to use at first. XDA lists several different ways to root the SIII, just read up on the forums for things to look out for and any possible fixes before trying any. Plus, it voids your warranty by rooting, until you unroot your device, so that isn't something to worry about. I trust XDA the most, but other sites like Android Central are just as trustworthy because many of the things there come from XDA or the developers there. Extra advice: if it doesn't work the first time, try again as it might take 2 or more times (4 for me) to get it to kick in and finish properly. If by the 5th time it still doesn't work, try another method.

      CWM allows you to install ROMs, software packages, backup your phone (basically imaging your phone so you can get your phone back to a previous state while keeping all settings and apps the way they were in case you want or need to go back no matter what happens) and much more. It makes life much easier to modify your phone with very little risk. It isn't a necessity, but most will call it a must have for a fail safe.
