Install LineageOS on
LG K10

Basic requirements

1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
2. Make sure your computer has adb. Setup instructions can be found here.
3. Enable USB debugging on your device.
4. Make sure that your model number is one of the following (exact match required!):
   • K420N
   • K420DS
5. Boot your device with the stock OS at least once and check every functionality.
6. LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Rooting your device

1. Root your device by following this guide.

Installing a custom recovery using dd

1. Download a custom recovery - you can download TWRP. Simply download the latest recovery file, named something like twrp-x.x.x-x-m216.img.
2. Place the recovery image file on the root of /sdcard:
   • Using adb: adb -d push <recovery_filename>.img /sdcard/<recovery_filename>.img
   check

   Tip: The file may not be named identically to what stands in this command, so adjust accordingly.
   • 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 -d shell from a command prompt (on Windows) or terminal (on Linux or macOS) window. In that shell, type the following commands:

   su
   dd if=/sdcard/<recovery_filename>.img of=/dev/block/bootdevice/by-name/recovery
   

4. Reboot into recovery.
   • From the same shell, type the following command:

     reboot recovery
     

Installing LineageOS from recovery

1. Build a LineageOS installation package.
2. If you are not in recovery, reboot into recovery:

   • With the device powered off, hold Volume Down + Power until the LG logo appears, then release Power for a second and hold it again until the recovery comes up.

     Note: Accept the factory reset prompt using the hardware buttons. If you have done everything correctly, this will not actually reset your device but instead will boot the custom recovery.
3. Now tap Wipe.
4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
5. Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions and then Swipe to Wipe.
6. Sideload the LineageOS .zip package:
   • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
   • On the host machine, sideload the package using: adb -d sideload filename.zip.
     check

     Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

Installing Add-Ons

1. Repeat the sideload steps above for all desired packages in sequence.

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

• Run adb -d reboot.
