Rooting the Samsung Galaxy S3….

Ok, firstly this post is only applicable to UK users of the S3, with a model number S3 I9300. Please, if you’re in the US with a T-Mobile, AT&T, VERIZON, or SPRINT VERSION of the Galaxy S III this post isn’t suitable for your handset and you’ll encounter problems should you attempt to root it and possibly brick the handset. There are other posts I’ve seen suited to these devices. A simple Google search should yield some resources.

Six or so months ago, I got the Samsung Galaxy S3 on a 2 year contract with the UK provider, Three network. It’s great I love it and I was happy with the current user privileges as most users are until more recently having read the benefits or performing a root on the device (namely ridding my handset of Bloatware and the after root use of removable storage through USB which doesn’t require an app). I’d often wondered if rooting would present me personally with a better handset and under the belief it would and after doing some homework undertook the task. I’ve since wondered if my Nexus 7 was a worthy endeavour but that’ll likely come later. Having done the reading, mostly which highlighted the pros and cons, I decided to take the plunge and root my device. At this point I’ll stress I’ve only rooted it – I haven’t flashed the ROM!. It remains a stock ROM, shipped with the handset I got out of the box. I may decide to do that next step later depending on how things go and moreso if i decide to overclock it as opening up more potential is appealing to me, yet I also like the idea of further measures to lengthen battery life that some custom ROM provide. I’m yet to do some more research first into what particular ROM I’d use. I think if I did do it based on what I’ve read so far, I’d most likely go with the ClockworkMod as it yields the most benefits and is the most popular amongst reviews.

Anyway, rooting the device itself isn’t really that difficult, yet it’s not without a potential risk of Bricking the handset as I’ve already warned. I had no immediate problems and after reading some forums and taking a step by step guide, highlighted below in a simple walk through, things went successfully. Please, if you decide to undertake the root don’t blame me if the wheels fall off!. Like most worthwhile things in life it’s not without risk but as mentioned does provides user benefits unachieveable with the standard user access.

Step by step guide

A couple of initial important points firstly.

Before you get underway, as I said there’s downsides, namely the warranty of the phone will be voided aside from bricking if the root goes badly – you can unroot it if you need to return the device on warranty should a normal issue arise. In order to get things back, you’ll apply stock firmware and unroot. If you’re very unlucky you’ll brick the device and that in itself is a world of pain and anguish!.

Again, US users, please DO NOT USE THIS ON YOUR T-MOBILE, AT&T, VERIZON, OR SPRINT VERSION OF THE GALAXY S III. This post is tailored solely to UK and European S3 users.

Downloading Required Files

  • Goes without saying, make sure you back up all your important data firstly. There are apps to accomplish this in Google Play
  • Make sure you’ve ample battery – 80% is required – I’ll assume as the process requires a PC, you’ll use that as a charging source if you’ve insufficent battery as I did.
  • Enable the USB debugging mode in Settings. Simply, that’s Home screen>Settings>Developer Options>USB Debugging
  • Download the complete Rooting Package from here to your computers Desktop and extract the zip file.
  • Download the Odin tool from here and for ease also place that on the Desktop.

The process itself

  • Launch the Odin as Administrator by right clicking on: Odin3 v1.85.exe file.
  • If the phone is connected properly, one of the ID:COM boxes will turn yellow with the COM port number.
  • Turn OFF your Galaxy S3.
  • Boot your phone into the download mode. You can do so by pressing and holding Volume Down+Home+Power keys simultaneously. Funnily enough, my S3 requires the Volume button to be pressed upwards.
  • When the phone is in download mode, connect it to your PC using the USB cable.
  • Now, from the Odin tool, click on PDA button and select the CF-Insecure-SGS3_XX_NEE_ALE8-v1.2.tar file which you extracted from the rooting package archive saved earlier to your Desktop.
  • Click the Start button and it will begin the process to root your phone.
  • Once the rooting is done, head over to Google Play and download the Superuser app. Once you run that afterwards and grant access it’ll inform you as to whether the rooting process was a success

Nexus 7 root

I’ve also just rooted (Not flashed the ROM) my Nexus 7 and have a OTG lead in the post which will be useful (adding extra memory will be a bonus via USB). Here’s a good video to walk/talk you through that root process also, again step by step. It’s very straightforward, aptly entitled, ‘The Idiots Guide’.

Phew, you’re done and I’m hoping successfully!. You should now be a Super User and you also should have access to the system files of the phone so you’ll now have the ability to rid it of some pesky Bloatware should you wish to.

I hope this has been of some use. Please comment below with your thoughts and experiences. I’m always happy to hear of other users views.
