Basic requirements

  1. Make sure your computer has working adb. Setup instructions can be found here.
  2. Enable USB debugging on your device.

Rooting your device

  1. Download TowelRoot from here.
    1. Click the large lambda symbol to download the apk.
    2. Install and run the apk to achieve root.

Installing a custom recovery using dd

  1. Download a custom recovery - you can download TWRP, simply search for your device on that page and download the corresponding recovery file, named something like twrp-3.0.0-v410.img.
  2. Place the recovery image file on the root of /sdcard:
    • Using adb: adb push twrp-3.0.0-v410.img /sdcard/twrp-v410.img
    • You can use any method you are comfortable with. adb is universal across all devices, and works both in Android and recovery mode, providing USB debugging is enabled.
  3. Now, open an adb shell from a command prompt or terminal window. In that shell, type the following commands:

     su
     dd if=/sdcard/twrp-v410.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
    
  4. Manually reboot into recovery:

Installing LineageOS from recovery

  1. Download the LineageOS install package that you’d like to install or build the package yourself.

    • Optionally, download 3rd party application packages like Google Apps
  2. Place the LineageOS .zip package, as well as any other .zip packages on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    • You can use any method you are comfortable with. adb is universal across all devices, and works both in Android and recovery mode, providing USB debugging is enabled.
  3. If you aren’t already in recovery, boot into recovery:
  4. (Optional, but recommended): Select the Backup button to create a backup.
  5. Select Wipe and then Advanced Wipe.
  6. Select Cache, System and Data partitions to be wiped and then Swipe to Wipe.
  7. Go back to return to main menu, then select Install.
  8. Navigate to /sdcard, and select the LineageOS .zip package.
  9. Follow the on-screen prompts to install the package.
  10. (Optional): Install any additional packages using the same method.
  11. (Optional): Root the device by installing the LineageOS su add-on (use the arm package) or using any other method you prefer.
  12. Once installation has finished, return to the main menu, select Reboot, and then System.
