: Since the previous root method that worked in ICS has been blocked in Jelly Bean. I've decided to create this simple guide (loosely based on this thread ) that will allow you to root, flash a custom recovery of your choosing, and unlock the bootloader on your Verizon Galaxy S III device if you just received the official Jelly Bean OTA ().
