Method 1: Via ADB Shell

Out of the two non-root methods, this is a slightly technical one and requires a PC, but still, it should be your go-to choice as it doesn’t ask for your device’s IMEI number.

  1. To begin with, download and extract Android SDK Platform Tools on your PC.install adb platform tools windows
  2. Then enable USB Debugging on your device and connect it to the PC via USB cable.Enable Engineer Mode oneplus

  4. Then go to the below location:
    /mnt/vendor/persist/engineermode/
  5. There you should find the engineermode_config file, open it via the text editor.
  6. It will have the following contents:
    encrypt_app=true
    encrypt_adb=true
    rc4_key=**********************
    imei=*******************
    last_download_time=***********
    encrypt_log=true
  7. Change the value of encrypt_app and encrypt_adb to False, i.e.
    encrypt_app=false
    encrypt_adb=false
    rc4_key=********************************
