Note: DISCLAIMER

Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

WARNING:

This guide is for advanced users and does not come with support. It is provided as a means to install CyanogenMod. A working adb connection as well as adb being in your PATH is required for this guide and users should not proceed without this. Additionally, you must be a 4.2.2 or older build or this will not work. In fact, if you try to use this method on a newer revision, you will almost certainly brick your device. Seriously don't try it. Downgrading won't work either. If you've updated, a qfuse is already tripped and any attempt to downgrade will also result in a brick.

Flash alternate bootloader and custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

In order to use CyanogenMod on the Verizon variant of the Galaxy S3 you need to load an older bootloader.

  1. Download the following files:
  2. Download the Heimdall Suite:
    • Heimdall Suite Download
    • NOTE: The windows version of Heimdall Suite requires the Microsoft Visual C++ 2012 Redistributable Package to be installed on the computer, which can be downloaded here.
    • Building From Source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README provided on Github.
  3. Boot to download mode on the Galaxy S3 (Verizon) by holding Volume Down, Home, & Power. Connect device via USB.
    • Optional: Once in download mode, verify Heimdall can detect the device and read its PIT file:
      • heimdall detect
      • heimdall print-pit
  4. Flash the aboot.mbn file from VRALEC.bootloader.tar.md5 with Heimdall:
    • heimdall flash --ABOOT aboot.mbn
  5. Flash the older kernel from VRALF2.boot.tar.md5 with Heimdall:
    • heimdall flash --BOOT boot.img
  6. You should now be able to download and flash recovery:
    • TWRP Recovery: download
      • md5sum:cfe85d27700b9ea564402d06aa43aaa9
    • heimdall flash --RECOVERY your_recovery_image.img
  7. Unplug USB cable. Boot to recovery mode on the Galaxy S3 (Verizon) by holding Volume Up, Home, & Power.
    • Flash the VRALE6.bootloader.zip in recovery
      • Install zip from sdcard
      • Choose zip from external sdcard
      • Select VRALE6.bootloader.zip
      • Confirm installation
      • Reboot

The device is now ready to flash CyanogenMod.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod package for your device that you'd like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Volume Up, Home, & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod the first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.
