Warning: The provided instructions are for LineageOS 14.1. These will only work if you follow every section and step precisely.
Do not continue after something fails!

Basic requirements

Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
Boot your device with the stock OS at least once and check every functionality.
LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Installing a custom recovery using `edl`

Download a custom recovery - you can download one here.
Connect your device to your PC via USB.
On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
adb reboot edl
```
You can also boot into edl mode via a key combination:
- With the device powered off, hold Volume Up + Volume Down + Power.
Flash recovery onto your device by following this guide.

Installing LineageOS from recovery

Build a LineageOS installation package.
- (Optionally): If you want to install an application package add-on such as Google Apps (use the arm64 architecture), please read and follow the instructions on Google Apps page
If you are not in recovery, reboot into recovery:
- With the device powered off, hold Volume Up + Power.
Now tap Wipe.
Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions and then Swipe to Wipe.
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 sideload filename.zip.
  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

Note: If you don’t want to install any add-on (such as Google Apps), you can skip this whole section!

Warning: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!

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 reboot.

Note: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance.

Warning: Depending on which recovery you use, you may be prompted to install additional apps and services. We strongly advise you to opt out of installing these, as they may cause your device to bootloop, as well as attempt to access or corrupt your data.

Get assistance

After you’ve double checked that you followed the steps precisely, didn’t skip any and still have questions or got stuck, feel free to ask on our subreddit or in #LineageOS on Libera.Chat.
