T-Mobile subscribers started receiving a notification for a new Android 4.3 Jelly Bean update with the build number of 10.4.C.0.814 rolling out. Since many of you are up and running on the software, some of you want to find root access. We are here to offer that help today.

The steps here are specifically for those running the aforementioned firmware build number. Do not try to install the update on any other device other than the model number C6606 and running the firmware number in the title.

The method we are using today is the Towel Root. You don’t need to be an advanced Android user to use the guide. However, some guidance from those with experience is advised. Customizing your device and unlocking the system internal always comes a ta risk. The warranty is void after the steps.

4.3 Jelly Bean

Details of Note

  • Download and install applications available from the Google Play Store such as Helium to aid you with backing up the data. Rooting generally wipes the data from the ROM. However, you can back up the phone contacts, videos, pictures, EFS folder and all other data you want to keep to the devices internal storage memory. The memory does not get wiped. You can use the external SD card if you prefer but it’s not necessary. Those with the internal system unchained from the default factory restrictions already will prefer taking a Nandroid backup and using apps such as titanium. You can use other such as SMS backup+ to help you make copies of the text messages you wish to keep.
  • The antivirus, spyware protection and malware protection can interfere with proceedings. That’s why we recommend you temporarily disable them until you start browsing the web again. there is no virus inside any of the files we are presenting in this guide.
  • Make sure you enable USB Debugging mode. Some devices running Android 4.2 have this menu hidden and it requires you to tap on the build number seven times. However, since we know you are running 4.3, the menu isn’t hidden. You can anytime access is from the settings menu. Click the Developer Options menu and enable USB Debugging mode inside.
  • Use the guide only if you have the Sony Xperia Z handset. Don’t attempt to install the files on any other device, as you will soft-brick or hard-brick the mobile. Moreover, make sure you have the latest USB Drivers installed. Transferring from the computer to the smartphone SD card or internal memory is the safest way to use files. You must have the drivers to connect to the PC. Most of you have them already. If you are connecting to the computer and can get access to the data from the phone, you know it’s working.
