Install LineageOS on otus

Basic requirements

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

Unlocking the bootloader

1. Connect the device to your PC via USB.

2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

    adb reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Down + Power. On the next screen use Volume Down to scroll and then press Volume Up to select.

3. Once the device is in fastboot mode, verify your PC finds it by typing:

    fastboot devices
   

   Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.

4. Now type the following command to get the bootloader status:

    fastboot oem device-info
   

5. Follow the instructions at Motorola Support to unlock your bootloader.

   Note: If your device is not supported by the Motorola Bootloader Unlock website, you will need to use an alternative bootloader unlock method like SunShine.
6. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

1. Download a custom recovery - you can download TWRP.

2. Connect your device to your PC via USB.

3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:

    adb reboot bootloader
   

   You can also boot into fastboot mode via a key combination:

   • With the device powered off, hold Volume Down + Power. On the next screen use Volume Down to scroll and then press Volume Up to select.

4. Once the device is in fastboot mode, verify your PC finds it by typing:

    fastboot devices
   

   Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.

5. Flash recovery onto your device:

    fastboot flash recovery twrp-x.x.x-x-otus.img
   

   Tip: The file may not be named identically to what stands in this command, so adjust accordingly.
6. Now reboot into recovery to verify the installation:
   • With the device powered off, hold Volume Down + Power. On the next screen use Volume Down to scroll to recovery and then press Volume Up to select.

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 such as Google Apps (use the arm architecture)
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, reboot into recovery:
   • With the device powered off, hold Volume Down + Power. On the next screen use Volume Down to scroll to recovery and then press Volume Up to select.
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.
    Note: If you want any Google Apps on your device, you must follow this step before the first reboot!
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.
