How to make long messages be sent as concatenated SMS on the Fx0

With the original Japanese firmware on the Fx0, messages with more than 160 characters are sent as MMS. See instructions below concerning how to make long messages be sent as concatenated SMS.

  1. Stop SMS app on device.

  2. Create backup of app:

    $ adb root
    restarting adbd as root
    $ adb shell
    root@madai:/ # mount -o remount,rw /system
    root@madai:/ # cd /system/b2g/webapps/
    root@madai:/ # cp
    root@madai:/ # exit
  3. Download app:

    $ mkdir
    $ cd
    $ adb pull /system/b2g/webapps/
    $ unzip
  4. Change maxConcatenatedMessages from 1 to 10 in:

  5. Upload updated app:

    $ zip -f gaia_build_defer_index.js js/settings.js
    $ adb push /system/b2g/webapps/

    Find the updated in this repository.

  6. Start app on device and send a sufficiently long message as a test.

Credits go to cutol for discovering that “JP also has maxConcatenated msgs set at 1, where in stock its 10.”
