Install CM for jflteatt

From CyanogenMod
Jump to: navigation, search


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.


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 on build I337UCUAMDB or I337UCUAMDL 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.

Root your Samsung Galaxy S4 (ATT)

If you have the latest version (JDQ39.I337UCUAMF3), follow this guide, but DO NOT try to flash a recovery image. Otherwise, follow the steps below:

  1. Download motochopper (credit to djrbliss).
    md5: a2a361dc1a1122b9034d4be4ba355a46
  2. Extract all files in the zip.
    • Windows only: install the latest Samsung USB drivers.
  3. Enable USB debugging on the device and connect device to PC.
    • Windows: run the run.bat file.
    • Linux/OSX: ./
  4. You now have root, proceed to next section.

Prepare and flash your recovery image

  1. Download TWRP Recovery

  2. Rename to: recovery.img
  3. Using Heimdall, run heimdall flash --RECOVERY recovery.img
  4. Reboot into recovery and proceed to next section.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build 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 /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.
    • Vol 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 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.
