Install /e/OS on a OnePlus Nord N200 - “dre”

The instructions in this guide will assist you to install /e/OS on your dre. 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.

Downloads for dre

To understand the difference between /e/OS builds check this guide

  • Before following these instructions please ensure that the device is on the latest Android 12 firmware.

  • If your device is currently using a newer or older version than the required version, please upgrade or downgrade to the required version before proceeding with your /e/OS installation.

  • The required version is Android 12 , which may be lower than the /e/OS version you are about to install - this is not an error! If there are multiple updates of that version (e.g. security updates), make sure to use the latest!

  • If you need to upgrade or downgrade your device, please search online for guides. We are unable to provide specific instructions here and on our support platforms.

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.

  1. Enable OEM unlock in the Developer options under device Settings, if present.

  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 Up + Volume Down + Power.
  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. Now type the following command to unlock the bootloader:

     fastboot oem unlock

  6. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.

  7. Since the device resets completely, you will need to re-enable USB debugging to continue.

Flashing additional partitions

Warning: This platform requires additional partitions to be flashed for recovery to work properly.The steps to flash the partitions are given below
Tip: In case the partition files are not available in the /e/OS recovery zip, users can try and download them from the LineageOS wiki install page specific to this device and OS build.
  1. First unzip the /e/OS Recovery file linked in the section marked Downloads for dre . The following files would show up in the location where you unzipped the contents of the eRecovery zip file
    • dtbo.img
    • vbmeta.img
    • vendor_boot.img
  2. Next we manually reboot into bootloader or download mode
    • With the device powered off
    • hold Volume Up + Volume Down + Power.
  3. Flash the downloaded image files to your device by typing (replace <...> with the actual filenames): 
    fastboot flash dtbo <dtbo>.img
fastboot flash vbmeta <vbmeta>.img
fastboot flash vendor_boot <vendor_boot>.img

Temporarily Booting a custom recovery using fastboot

  1. Connect your 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
  3. Once the device is in fastboot mode, verify your PC finds it by typing: 
     fastboot devices
  4. Flash a recovery image onto your device 
     fastboot flash boot recoveryfilename.img

    Replace the recoveryfilename with the name of the recovery image you downloaded in the previous section

  5. Manually reboot into recovery mode
  • With the device powered off
  • hold Volume Down + Power
Tip: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.

Ensuring all firmware partitions are consistent

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

In some cases, the inactive slot can be unpopulated or contain much older firmware than the active slot, leading to various issues including a potential hard-brick. We can ensure none of that will happen by copying the contents of the active slot to the inactive slot.

To do this, sideload the copy-partitions-20220613-signed.zip package by doing the following:

  1. Download the copy-partitions-20220613-signed.zip file from here. It should have a MD5 sum of 79f2f860830f023b7030c29bfbea7737 or a SHA-256 sum of 92f03b54dc029e9ca2d68858c14b649974838d73fdb006f9a07a503f2eddd2cd.

  2. Sideload the copy-partitions-20220613-signed.zip package: * On the device, select Apply Update, then Apply from ADB to begin sideload. * On the host machine, sideload the package using: adb sideload copy-partitions-20220613-signed.zip

  3. Now reboot to recovery by tapping Advanced, then Reboot to recovery.
