Install /e/OS on a OnePlus Nord - “avicii”

The instructions in this guide will assist you to install /e/OS on your avicii. Please read through the instructions at least once before actually following them, so as to avoid any problems later.

It is advisable to flash your device only if you know what you are doing and are ok taking the associated risk. All /e/OS builds are provided as best effort, without any guarantee. The /e/OS project and its project members deny any and all responsibility about the consequences of using /e/OS software and or /e/OS services.

Requirements

If required take a backup of all important data from your phone on an external storage device before proceeding.
Do not take a backup on the same device as some of these actions will format the device and delete the backup.
Ensure your phone is charged more than 50%
Check that adb and fastboot are enabled on your PC. If not you can find the setup instructions here
Download all the files and images mentioned in the download section below before starting the installation
Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.
Enable USB debugging on your device. You can find the instructions here
Make sure that your model is listed in the Smartphone Selector. Check the model supported. Where available, information on the model supported should show as a pop-up when you hover the cursor on the Device name. The model number supported should be the exact same.
Boot your device with the stock OS at least once and check every functionality.

Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it will not work on /e/OS as well. Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.

Unlocking the bootloader

Tip: The steps given below only need to be run once per device.

Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or an online drive

Warning: Some vendors/manufacturers prevent the bootloader from being unlocked. Depending on where your device was acquired you may or may not be able to unlock the bootloader. To verify if your device is compatible please check the devices list.

Enable OEM unlock in the Developer options under device Settings, if present.
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 bootloader
```
You can also boot into fastboot mode via a key combination:
- With the device powered off
- hold Volume Up + Volume Down + Power.
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.
Now type the following command to unlock the bootloader:
```
 fastboot oem unlock
```
If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.
