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.
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.
- 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>
Method 1 (VRBLK3, MB1 & MD3 Builds)
Since this tutorial is for Galaxy S3 I535 on Android 4.1.1 and 4.1.2 both, download the files accordingly- only different being the stock bootchain file. For the sake of convenience put all the downloaded files in one folder.
These are important but mandatory files. If you have them, just skip:
- Download the Odin tool and extract the zip on your desktop: Odin3-v3.07.zip — Mirror
- Download Samsung USB Drivers and install on your computer. Skip if you already have it: Download
These two files are meant to be downloaded by all:
- Download the custom Bootchain file: VRALEC.bootchain.tar.md5 — Mirror
- Download CWM Recovery: CWM6023TouchVZW.tar.md5 — Mirror
Download one of the following files depending on what you want:
- Download SuperSU file (for Root Only): CWM-SuperSU-v0.99.zip
- Download SuperUser file to (Root and Unlock Bootloader both): SuperSU_Bootloader_FIXED.zip — Mirror
Download one of the following bootchain files depending on firmware version of your Galaxy S3 SCH-I535:
Make sure you download the correct file. Go to Settings> About, check firmware version and download the matching file.
- Bootchain file for VRBLK3 (Android 4.1.1 JB): VRBLK3_Bootchain.tar.md5 — Mirror
- Bootchain file for VRBMB1 (Android 4.1.2 JB): VRBMB1_Bootchain.tar.md5 — Mirror
- Bootchain file for VRBMD3 (Android 4.1.2 JB): VRBMD3_Bootchain.tar.md5 — Mirror
If you have recently updated your Galaxy S3 with official VRBLMD3 OTA update, you should choose VRBMD3_Bootchain.tar.md5 from above.
And if you have updated your device with the recently released VRBMF1 update, use Method 3 to root your phone.

- Now pull out the back cover of the phone and remove the battery. Place the battery to its place after about 30 seconds.
- Then boot the phone into ClockworkMod recovery mode. To do this, hold the Volume Up + Home + Power buttons simultaneously. Keep the 3 keys pressed till your phone vibrates and when it does, release the Power button but keep the other 2 keys pressed till you see a gray/black background with blue text the Clockworkmod Recovery written on the top of the screen.
- Since it’s touch recovery, you can either select options by tapping, or using the volume and power keys.
- Okay, now go to “install zip from sdcard> choose zip from sdcard” and select the “SuperSU_Bootloader_FIXED.zip” file.
- Confirm your choice by selecting “yes” and let the installation finish.
- When it’s done, go back and select “reboot system now”. But before your phone boots, pull out the battery and place it back after a few seconds.

- Relaunch Odin, connect the phone to PC, click on PDA button and select the stock bootchain file (either VRBLK3 orVRBMB1 or VRBMD3) depending on what file you have downloaded.
- Click the Start button to initiate the installation. When it is finished, you will see PASS!/RESET! message followed by an automatic reboot of your Galaxy S3. You can disconnect the cable now.
