Enabling Engineer Mode on a OnePlus smartphone via ADB Shell requires a few steps, but it is a more advanced method that can be used if the previous method does not work. Here is a guide to enable Engineer Mode on a OnePlus smartphone via ADB Shell:

  1. Connect your OnePlus smartphone to a computer via a USB cable.
  2. Open a command prompt or terminal on your computer.
  3. Type “adb devices” to ensure that your device is recognized and connected to the computer.
  4. Next, type “adb shell” to enter the device’s shell.
  5. Now, you will receive a pop-up to grant the USB Debugging on your phone.

  2. Once your device is rooted, download a root file manager app, such as ES File Explorer or Root Explorer.
  3. Open the root file manager app and navigate to the System folder
  4. You have to grant SuperUser permission to access the system files.
  5. Now go to the location given below.
    /mnt/vendor/persist/engineermode/
  6. Now inside this folder, look for file name engineermode_config.
  7. Once you find it, open the file in text format.
  8. Scroll down and look for the content
    encrypt_app=true
    encrypt_adb=true
    rc4_key=**********************
    imei=*******************
    last_download_time=***********
    encrypt_log=true
  9. Change that above line with the below-given value
    encrypt_app=false
    encrypt_adb=false
    rc4_key=********************************
    imei=*******************
    last_download_time=*******************
    encrypt_log=true
  10. Save the changes to the file and exit the text editor.
  11. Reboot your device.
  12. After rebooting, open the dialer app and dial *#808#. This will open the Engineer Mode on your OnePlus device.
  13. You can access various advanced settings and features in the Engineer Mode menu, such as Function Switch, Debugging Tools, and Fingerprint Calibration.

It is important to note that enabling Engineer Mode on your OnePlus device via Root requires root access, which can potentially void your device’s warranty. Additionally, modifying system files and settings may cause your device to malfunction or become unstable if done incorrectly. Therefore, it is recommended that you proceed with caution and only attempt this method if you have sufficient knowledge and experience in rooting and customizing Android devices.
