A number of Samsung fans were unsatisfied by the fact that all variants of the Samsung Galaxy S3 come with unlocked bootloaders, except the one provided by Verizon. Although it might have been a condition laid down by the network operator, fans started blaming Samsung.
But this is about to change as the root is now achievable on the Verizon Galaxy Nexus despite the locked bootloader. You will find some rather simple steps below if you know how to hack into a device. Otherwise, go ahead at your own risk.
Note: Do not attempt this hack if you've disabled apps. Re-enable them first or use the stock ruu from here before attempting this. You'll also need some files that will basically flash a custom system.img.ext4 which your su binary has. When you’ve done that, boot up and flash cwm.
Here are the steps (You will find all the required download links below)
Step 1: Boot into Odin mode on the phone. Do this by powering off and then holding vol down, home and power to power on. Then press vol up to accept the disclaimer. Plug into your computer.
Step 2: Fire up Odin (Heimdeil may work in linux but it hasn’t been tested as yet) and choose the PDA section and browse to wherever you downloaded rooted.system.img.tar, and then click flash. This make take a bit of time so be patient.
Step 3: Now it will auto reboot. It should boot up and thing should act mostly normal except that you'll be able to adb in and use su to take root
(If you don't want a custom recovery, you may stop here. You are rooted. You can continue following the steps to get CWM on your device)
Step 4: You'll need adb installed and working for this. If you don't know how,open a command prompt and follow these commands –
Code: adb push recovery.img /sdcard/
adb shell
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18
reboot recovery
Step 5: Lastly, Flash this in CWM (It’s a stock Samsung Boot animation). It should be done by now.
