Mobile Device Management (MDM)

NitroPhones can be centrally managed by using open source Headwind MDM.

Depending on whether you are using the paid or gratis license, some features might be available or not.

Install MDM on NitroPhone

Important

We recommand to backup your data before installing MDM.

Your NitroPhone needs to be connected to the internet during the configuration and you also need a PC.

To grant special permissions you need to use ADB (Android Debug Bridge). You can use ADB directly from your Browser with WebADB (easier, recommended), or you can install the CLI tool on your computer (alternative). WebADB is currently only compatible with Chromium-based browsers (e.g. Chrome, Microsoft Edge, Opera).

Installation With WebADB

  1. Download locally on your PC the latest HMDM Android app (launcher). It is important that this version matches your HMDM server configuration. You can also download the desired version here: https://h-mdm.com/files/hmdm-<version>-master.apk

  2. On your NitroPhone, enable the developer options: Settings -> About Phone -> Press 6 times on “Build number”.

  3. Enable USB debugging: Settings -> System -> Developer Options -> USB debugging.

  4. Connect the smartphone to the PC and change the charging connection to “File transfer”.

  5. On your PC go to WebADB.

  6. At the top left of the page click on “Add” select your NitroPhone and click on “Connect” and click again on “Connect” next to “Add”

  7. On your NitroPhone allow the connection.

  8. In the WebADB menu choose “Install APK” and click on “Open” and choose the previously downloaded APK.

  9. Once completed, in the WebADB menu choose “Interactive Shell”. If you have this error: “Application error: a client-side exeption has occurred” refresh the page or click to “File Manager” and go back to “Interactive Shell”. If you see <your android version name>:/ $ then you are properly connected.

  10. In the shell type:

    dpm set-device-owner com.hmdm.launcher/.AdminReceiver

    If it was successful it says:

    Success: Device owner set to package com.hmdm.launcher/.AdminReceiver
Active admin set to component com.hmdm.launcher/.AdminReceiver

  11. Now you can open “MDM agent” on your NitroPhone. If any permissions are asked, allow them.

Your HMDM app is ready to use. Refer to “Register NitroPhone on HMDM Server” at the end of this page.

Installation With ADB

  3. Enable USB debugging: Settings -> System -> Developer Options -> USB debugging.

  4. On your PC, download ADB.

  5. Unzip the downloaded archive and open a terminal in this folder.

  6. Connect the NitroPhone to the PC and change the charging connection to “File transfer”.

  7. Test if adb can find your NitroPhone:

    ./adb devices

    You need to see your device listed in the output.

  8. Install the HMDM app via:

    ./adb install <name of your downloaded file>.apk

    When the MDM installation was sucessful, the output of adb is “Success”.

  9. Now give the app device owner rights:

    ./adb shell dpm set-device-owner com.hmdm.launcher/.AdminReceiver

    If it was successful it says:

    Success: Device owner set to package com.hmdm.launcher/.AdminReceiver
Active admin set to component com.hmdm.launcher/.AdminReceiver

  10. Now you can open “MDM agent” on your NitroPhone. If any permissions are asked, allow them.
