Rooting an Android device has many privileges. Having rooted your phone once, you are able to use third-party custom ROMs and mods that require a custom recovery to be installed. Besides, there are hundreds,or say thousands, of app that are capable of doing wondrous things and enhance your phones performance and usability. But this humble eulogy of rooting cannot undermine the hazards associated with it.

Rooting a Samsung Galaxy device is much easier than rooting any device manufactured by other OEMs but when it comes to rooting a Samsung phone from Verizon, things get a little more complicated and rounded. However, complicated it might be, it cannot stop our great Devs to crack the nut. All props and credit for the method described here goes to XDA member open1your1eyes0.

Disclaimer:

Please note that the procedure of unlocking the bootloader, rooting and installing a custom recovery on your Verizon Galaxy S3 SCH-I535 is considered risky. Moreover, it will also void the warranty of your phone. Proceed only when you are sure what you are going to do and understand the  seriousness of things. More than anything, be careful while following the steps.

Prerequisites:

  • Charge your phone to have at least 60% of battery juice.
  • Rooting does not wipe any data from your phone but we would strongly recommend that you backup all your contacts, messages, call-log, apps, etc. Here are some good free apps to help you with backing up your data.
  • Put your device in USB Debugging mode from Settings> Developer Options>
