Yesterday, I’ve created a post that helped you install the ClockworkMod Recovery on your T-Mobile Galaxy S3 smartphone, function that now can be used to flash the root files on the same device. Read the entire tutorial and if you are an advanced Android user then you shouldn’t have any problem in rooting your T-Mobile Samsung Galaxy S3.
If you decide to root the Galaxy S3 on T-Mobile, then you will lose its warranty and if you ever wish to restore it then you will have to return to its stock firmware, which will eventually revoke root access. However, if you still wish to root the device then you should read the entire post and make sure that you do not skip any of the steps listed below.
Rooting your device will bring access to your phone’s sub system and this means that you will gain control over all ROM firmware settings. Also, root access along with CWM Recovery brings you support for installing new custom ROMs, that will eventually improve the performances of your Galaxy S3 and offer you the possibility to fully customize the Android OS and make it look just like you want it. Now you should move to the preparation guide and learn what you should do before starting to flash the root files:
- apply the root files only on Samsung Galaxy S3 T-Mobile edition. Do not attempt to root any other SGS3 model as you might brick it.
- install CWM Recovery before rooting the device because this feature is the one that we will use to root your phone.
- optionally, you can choose to backup some important files so that in case these will be corrupted then you will be able to restore them from your PC. Alternatively you can move these files on your device’s internal or external sdcard as these won’t be affected by the rooting process.
- do not attempt to apply the changes in the tutorial if you’re a beginner when it comes to work with Android sub system functions.
- rooting your device will void the warranty of your T-Mobile Galaxy S3. To revoke root access and restore the warranty of your Galaxy S3 you will have to flash the stock firmware. We should host such guide in the near future.
- Enable USB Debugging.
- Charge the phone’s battery until it reaches 60% power level.
Now that you know all the above, I think that you should be ready and move to the next step and learn how to properly apply the root on your smartphone. Please note that you’re rooting the device at your own risk and we cannot be held responsible in case you damage it. Remember to read all the instructions above and make sure not to skip any of the steps listed in the tutorial. If you cannot complete the root then you I strongly advise you to ask for our help in comments.
How to root T-Mobile Samsung Galaxy S2 using CWM Recovery:
- If your device has the CWM Recovery installed, then you should now download the root zip file from HERE (Do not attempt to root your device if custom recovery image isn’t installed). The zip is named CWM_SuperUser_v3.0.7, save it on your PC and after this connect your smartphone to it.
- Transfer the root zip file on the phone’ internal sd card. Leave the zip file unchanged and do not attempt to extract its contents, simply copy it on your phone’s internal sd card root location.
- After the files have been copied you should power OFF the T-Mobile Galaxy S3 and after that boot into CWM Recovery. It can be done by pressing ‘volume up’ + ‘home’ + ‘Power’ buttons. Wait for the Clockworkmod recovery to load and after that move to the next step. Use the volume buttons to control the custom recovery menu.
- Now, select the option that says ‘install zip from sdcard’ and from the new menu select ‘choose zip from sdcard’. Navigate and point recovery selection to the CWM_SuperUser zip file; the one downloaded at step 1 and moved on your device’s internal sdcard at step 2.
- Confirm that you wish to flash the root file and wait until the process completes.
- When the root is complete you will have to go back to the first CWM Recovery screen. Select ‘reboot system now’ and then wait for the phone to boot into its normal mode.
- Now, open the Play Store and install the BusyBox application on your phone.
- Launch BusyBox application on your T-Mobile Galaxy S3 device.
- Confirm that you wish to offer root access for BusyBox. Click the X to close the pop-up screen.
- Confirm the BusyBox scan of your device.
- Press the Install for Busybox to install all the files it needs in order to run correctly.
- When that installation is complete you are free to close BusyBox and that should be the last step you had to take in order to correctly root your Galaxy S3 on T-Mobile.
I hope that you found this guide helpful and that you’ve managed to successfully root and install BusyBox on your phone. In case you didn’t manage to root the device, then you should repeat the entire tutorial guide once again and this time you have to make sure that you apply all the steps I’ve listed above. Also, feel free to ask for our help by posting in our comments section.
Do not attempt to install the root on any other Galaxy S3 variant, as it will work only with the T-Mobile model. Remember that now that your phone is rooted, its warranty is now void and if you wish to restore it, then you should flash the stock firmware.
