Update SymphoTouch app on e:touch devices without internet

Introduction:

Normally, the e:touch does not have internet access; therefore, it is not possible to download from the Google Play Store. The product is designed to be connected to a network out of the box via PoE. It is necessary to connect the e:touch to the internet and log into the Google account to download latest update of the SymphoTouch app. This process is not always possible, as internet is not available everywhere. (It is necessary to disable “ethernet“ internet connection if Wi-Fi is used, ask Traxon | ecue support for Password to open settings)

Install SymphoTouch.apk without Google Play Store

If the SymphoTouch app needs to be installed without internet access, there is also the option of using ADB over USB-C with a Windows machine.
Download the latest SymphoTouch .apk or ask Traxon | ecue support for the latest SymphoTouch.apk file.

  1. Connect the android device to the Windows machine with a USB-C cable

  2. Press the “Set” button on the top of the e:touch with a needle and enter the password to open the settings

  3. Open the Device info setting and tap the build number 7 times to unlock the developer options and check if "USB debugging" is active

  4. Install Android Debug Bridge (ADB or Minimal Fastboot and ADB)

  5. Open a command prompt in the ADB installation folder

  6. Enter the following command to test whether the tablet is recognized as an ADB device via USB-C:
     adb devices 
    You should see an ID and "device"

  7. Run the following command in the command prompt:
    adb install "SymphoTouch.apk" 

  8. The prompt should show “Success” and the SymphoTouch app on the Android tablet should be closed.

  9. Reopen SymphoTouch on the Android tablet and check the version number under “About SYMPHOTOUCH” 

  10. Done!

Install SymphoTouch.xapk without Google Play Store

If an SymphoTouch.xapk is available, it is relatively easy to install via ADB:

  1. Connect the android device to the Windows machine with a USB-C cable

  2. Press the “Set” button on the top of the e:touch with a needle and enter the password to open the settings

  3. Open the Device info setting and tap the build number 7 times to unlock the developer options and check if "USB debugging" is active

  4. Install Android Debug Bridge (ADB or Minimal Fastboot and ADB)

  5. Open a command prompt in the ADB installation folder

  6. Enter the following command to test whether the tablet is recognized as an ADB device via USB-C:
     adb devices 
    You should see an ID and "device"

  7. Rename your .xapk file to .zip and unzip the file to the ADB installation folder.

  8. You will see a few .apk files, and sometimes also a folder Android which includes a .obb file (you can ignore the following files: icon.png and manifast.json).

  9. Run the following command in the command prompt:
    adb install-multiple "com.osram.SymphoTouch.apk" "config.arm64_v8a.apk" "config.en.apk" "config.fr.apk" "config.mdpi.apk" 

  10. If your XAPK file contains a .obb file (you should see a folder named Android), then run also the following:
    adb push Android\obb\com.osram.SymphoTouch /storage/emulated/0/Android/obb/

  11. The prompt should show “Success” and the SymphoTouch app on the Android tablet should be closed.

  12. Reopen SymphoTouch on the Android tablet and check the version number under “About SYMPHOTOUCH” 

  13. Done!
